Arsenic as the cause of CKDU

Arsenic issue, as usual, has taken a political direction. It cannot be helped as there is lot of politics around Arsenic. Politics in western Christian colonialism is bound with culture and the fight is not only against those who are responsible for the Chronic Kidney Disease unidentified etiology (CKDU) directly but against the cultural colonialists as well. The UNP, JVP and some three wheeler parties attempt to gain political mileage by accusing the government for not supplying the dialyzing machines and other equipment to the government hospitals in Padavi Sripura and other affected areas. However, western medicine that does not know the cause of the CKDU has no treatment for the disease. Dialyzing is not a cure and it is only a method of management of the disease. It is not bad idea to distribute filters but one should go to the root cause if one is interested in finding a lasting solution to the problem. We have found that Arsenic that comes from agrochemicals is the main cause of the disease and unless one stops agrochemical based agriculture the disease cannot be eliminated. Distribution of filters will maintain the filter producers and importers as well as Agrochemical firms. We have to find an alternative to agrochemical based agriculture meaning that we have to go back to Sinhala Govikama that did not kill pests and also to Sinhala Vedakama including Sinhala Nila Vedakama that has cure for the CKDu. Filters and dialyzing machines are only management of the disease and no better than “athisarate amuda geheema”. The CKDU has been in existence for more than two decades but neither the public, the so called intellectuals, the media nor the politicians paid any attention to it until we came out with the Arsenic issue, in connection with the CKDU. The irony is that the media in general, except for a very few newspapers and television channels, have forgotten the people who were responsible for informing that Arsenic is the cause of the CKDU.

Let us start at the very beginning. My attention to the CKDU was drawn by Dr. Channa Jayasumana, a probationary lecturer in the Department of Pharmacology at the Rajarata University. I have known Dr. Jayasumana from his student days at the University of Peradeniya and he had been interested in the subject of theory of knowledge (epistemology) for some time. When Dr. Jayasumana informed me of the plight of the patients in Rajarata I was naturally disturbed, and I thought of a way to help these innocent people who supply the food including the so called staple food. By this time I had been cured of several diseases by what may be called divine medicine through Mrs. Priyantha Senanayake who can communicate with a few whom she calls “deivaru” . Among them Natha Deviyan and Vipassaka Deviyan are the foremost in the sense that they are the most knowledgeable and also most spiritually advanced. I had no hesitation in directing Dr. Jayasumana to Mrs. Senanayake.

I am a Sinhala Buddhist and I am proud to be so, even though the Sinhala Buddhists at present are very imitative and hypocrite. The Sinhala Buddhists have a proud record of protecting Theravada Buddhism and building a rich culture that enabled the people to live in harmony with nature. The Sinhala Buddhists have acquired knowledge from the devas (Gods), like the ancient Greeks, Bharats and specially the Jews who have been in communication with their God who is known as Jehovah. The Greeks have obtained knowledge from their Gods such as Apollo, Jupiter and Goddesses such as Athena. In Bharat it is clear that they had had advice from Gods such as Krishna as in the case of Kuru Pandava “war”. The people either through meditation, yoga or some such method, reach high spiritual state and thus gain knowledge or become able to communicate with Gods from whom they acquire knowledge indirectly. The Sinhala Buddhists at least from the time of Arhant Mahinda Thero have recognized only “Prathyaksha” as a means of gaining knowledge, Buddha Prathyaksha being a very special kind of Prathyaksha. The Chullahaththipadopama Suththa the first Dhrama Deshana (For anybody’s sake not sermon) of Arhant Mahinda Thero to the Sinhala people was on “prathyaksha” as the only means of acquiring knowledge. I will come back to this aspect later, when discussing the so called scientific method. I had no doubt at all that Mrs. Senanayake obtained knowledge from whom she called Natha Deviyan and Vipassaka Deviyan as she did not know anything on Medicine, whether it is western, Ayurvedic, Sinhala or anything else. According to her the Medicine she practiced was “Sinhala Nila Vedacama” which she became “knowledgeable” of through the Devivaru.

When Dr. Jayasumana went to Mrs. Senanayake he was told by the Natha Deviyan and Vipassaka Deviyan that the main cause of the CKDU was Arsenic, the hard water and the particular soil called the “Kumburu Pasa” being the other two causes. What the Devivaru had told was that the “Kumburu Pasa” has a tendency to retain arsenic which finally mixes with the Calcium and Magnesium salts found in hard water. The arsenic gets into the Calcium and Magnesium salts in a peculiar way making it almost undetectable in hard water. The hard water or “kivul jalaya” contributes to the spread of the CKDU and people who consume water from “Vevas” that does not consist of much hard water are less likely to be victims of CKDU.

Now for mortals like us who have no direct experience with causative factors it is very difficult to identify the cause of something. Following Hume one may even say that there are no causes as such, as cause is not a direct experience. We only consider certain phenomena as causes of some others through induction and there is no way to “prove” that A is the cause of B. We after observing B following A on number of occasions come to the conclusion that A is the cause of B by induction, of course after having constructed the concept of cause. In any event in the case of CKDU the western medicine had not identified the cause of CKDU in Rajarata and other areas and thus called it Chronic Kidney Disease with unidentified etiology. I am told that Kidney diseases are caused of various factors Cadmium being one such causative factors. However western medicine had not identified CKDU as caused by Cadmium though Cadmium is the cause of one or several Kidney diseases. This meant that the symptoms of Kidney Diseases caused by Cadmium were not found among the patients of CKDU as if it was the case the western medicine practitioners at least from a western country could have come out with cadmium as the causative factor. As it is it did not happen, and the cause of CKDU in Rajrata and associated areas remained unidentified.

However, it must be said that a few years back a researcher from the Faculty of agriculture at Peradeniya, if I am not mistaken, had found that there was Cadmium in some fish in the Veavs of Rajarata and also in the lotus roots (nelum ala) and identified Cadmium with CKDU. It is true that some kidney diseases are caused by Cadmium and that Cadmium is found in Rajarata soil, fauna and flora. However, even if we do not go to the extent Hume went, from such data alone it is not possible to conclude that Cadmium is the cause of CKDU. As mentioned above the patients in Rajarata and associated areas did not show symptoms of Cadmium associated Kidney Diseases and the western medicine did not identify Cadmium as the cause of CKDU. Then some others had come out with fluoride as the cause of the CKDU but western medicine did not take much notice of these assumptions.

It was in this background that Mrs. Senanayake told us that Arsenic is the main cause of CKDU, with hard water and the particular soil known as “Kumburu Pasa” being the auxiliary causes. I presume that the devivaru did not have to go through what Hume had said on causative factors and they knew that Arsenic, Hard Water and the “Kumburu Pasa” are the causes of CKDU through some kind of “Prathyaksha”. Of course we did not have the means of showing that these were the causes of CKDU but we decided to test for Arsenic in soil, water and in the bodies of patients and also of those who had died of CKDU. Profs. Priyani Paranagama and Mala Amarasinghe of the Faculty of Science undertook to carry out the research associated with Arsenic with Dr. Jayasumana working as a postgraduate student. The latter registered for a postgraduate degree at the University of Kelaniya after all the relevant boards including the university senate approving his candidature for such degree. A special reference must be made on the commitment of and sacrifice made by Prof. Paranagama to see that the research was carried out successfully. Mainly due to her untiring effort the Kelaniya group was able to show that there was Arsenic in the samples of water, soil, flora and also in the body parts of patients. Instead of honouring Prof. Paranagama she was abused, intimidated, and threatened by people with vested interests. (To be continued)

Mathematics and Physics

I am afraid my senior colleague and friend Prof. Carlo Fonseka has not answered my question. The question I posed in my letter to the editor on 6th February 2012 was "why western mathematics ‘the subject in which we never know what we are talking about, nor whether what we are saying is true’ has been so effective in western physics" Without answering the question Prof. Fonseka make certain statements (The Island - 9th February 2012) , which are not that relevant. However, I will deal with them with pleasure.


Prof. Fonseka says to “seek comfort” he has “to understand what is happening” in his “environment in terms of cause and effect relationships i.e. gain knowledge about how nature works”. The comfort referred to by Prof. Fonseka may not be the same as what some others may mean by “comfort”. For example a Bodhsathva would have a different objective in life and there are many others who see “dukkha” in “comfort”. There are different attitudes to life in different cultures but unfortunately we are now dominated by western idea of “seeking comfort”. The knowledge systems created by people differ due to these differences among others, and it has to mentioned that Medieval Europe with attitudes based in Catholic culture was not able to create western science. It needed a revolution in Chinthanaya as I call it, in the sixteenth century.


Even if we forget these differences and go with Prof. Fonseka’s idea of “understanding” what is happening in the environment and gaining “knowledge about how nature works”, and assuming that western Physics tries to gain knowledge about how nature works, the question is how could it be done with Mathematics ‘the subject in which we never know what we are talking about, nor whether what we are saying is true’ in the words of Bertrand Russell. In Mathematics one is not bothered to “know” whether the axioms of the particular branch one studies is “true”, and all that one is interested is in obtaining some other propositions from those axioms using formal logic. My question is if western Physics tries to “gain knowledge about how nature works” how can it do the same with western Mathematics.


Prof. Fonseka says: “ I have gradually realised that the most reliable knowledge available to me has come from the collective experience of human beings living in the east or west, north or south who have observed aspects of the world with their five senses, used their reason to figure out causal explanations for their observations and then checking the validity of their explanations by putting them to the test of experience. Experience has shown humankind that in formulating causal explanations (hypotheses) the use of formal systems of reasoning has greatly contributed to the reliability and usefulness of the final outcomes. One such formal system is mathematics,” Now this is nothing but what was called scientific method before Popper and much water has flown under the Kelani Bridge as well as the Tower Bridge in London since then. As I am discussing these under my series of articles “on so called scientific knowledge I do not want to delve into it now. However I would like to ask how one knows that A = A as assumed in formal logic, in a world of “anicca”. With A = A there is no change (motion), and I have dealt with this problem in an article on “The logic of change”, published in “Kalyani” the journal of the University of Kelaniya.


Incidentally what Gödel proved was that any formal system that incorporates Arithmetic contains statements that are “Mathematically true” which cannot be deduced from its axioms. Prof. Fonseka may think that western Mathematics is “reliable” but then there were so many other systems that could be considered as reliable. It is true that I went to the UK many moons ago in an Air Ceylon airplane to write a thesis on “Relativistic gravitational effects in Astrophysics”. I had been interested in western Physics and Mathematics as a young person and situation demanded that I gain postgraduate qualifications to continue as a lecturer and I had to make that trip to the UK. However, I am much younger now and air travel is not a necessity at present. I seek no employment in any capacity nor any qualifications in western Science. In any event the motion of airplanes was based also on Newtonian Gravitation, which had been discarded as a “Theory of Gravitation” and shown that there was no gravitation as such by Einstein more than fifty years before I got into that airplane. However, the western scientists have still not discarded it and it is continued to be taught in schools and universities. So much for the “scientific method” and “reliable knowledge”.


People invent, construct instruments, concepts, theories etc., depending on their needs and it is needless to say that needs differ from culture to culture. After coming back from the UK to Sri Lanka then known as Ceylon in another Air Ceylon airplane (could have been the same airplane) I have realized that the westerners have imposed their needs on us through colonialism. I do not want to say there was the “dandumaonara” of Ravana constructed most probably due to some need of that society as an alternative to the airplane, but I can assure Prof. Fonseka who hold a very high position in an institution of the western medical profession, that there are hundreds of western medical doctors who have more faith in Sinhala Nila Vedakama than in western Medicine, probably because the former is more “reliable’, and moreover that some of them practise it.


Now since Prof. Fonseka has not answered my question I give my answer to the same. Western Mathematics is very abstract and western Physics is the most abstract among the western Sciences. Western Mathematics has not been very successful in western Physiology or western Biology for that matter, and the main reason for the effectiveness of western Mathematics in western Physics is this abstractness. Of course there is another reason for the effectiveness. Even in western Physics “we never know what we are talking about, nor whether what we are saying is true”, gravitation on which I worked for my thesis being the best example. However, that does not imply that “we know what we are talking about, and what we are saying is true” in other western sciences or for that matter in any “knowledge constructed by human beings due to Avidya.

Wave-particle duality of nature challenged at Kelaniya University

In 1807, Thomas Young demonstrated that light had wave properties by using a simple experiment now famously known as the Young’s double slit experiment. Young showed that the pattern of bright and dark fringes that forms on a screen when light passes through two narrow slits can be explained using the wave theory. Since Young’s revelations, the wave theory of light (of electromagnetic radiation in general) took firm root and dominated the physics world for nearly a century. Until Max Plank, in 1901, showed that the energy of the radiation emitted by heated objects was discretized as if light was actually composed of particles! Since the wave nature of light as demonstrated in the Young’s experiment could not be discarded, scientists reconciled that light had both wave-like and particle-like properties. As it turned out just as light possess particle like properties, particles such as electrons, neutrons and even large molecules like fullerenes possess wave like properties. In 1989 experiments conducted by Tonomura demonstrated that a beam of electrons passing through a double slit, as in Young’s experiment, actually forms a dark and bright fringe pattern on a screen next to it. It is believed that these interference patterns, as they are called, arise because of the wave nature of electrons.
Young’s double slit experiment is still an active research topic among physicists as they have not fully embraced the strange behavior of nature implied by it. Physicists have been particularly bothered by the fact that when a single electron, instead of a beam of electron is sent through the double slit what is observed on the screen is not a faint interference pattern but a single dot on the screen depicting an electron striking the screen. If an electron represented a physical wave of some sort then one would expect a series of bright and dark fringes, however faint it might be on the screen but not a single dot. This unexplained phenomenon is the focus of recent theoretical and experimental work conducted by Dr. Nalin de Silva and his student Suraj Chandana at University of Kelaniya.
Dr. de Silva rejects the wave nature of particles. According to him what gives rise to a bright and dark fringe pattern in the Young’s double slit experiment is not the so called wave nature but the particle nature itself though not necessarily those of ordinary classical particles. Dr. de Silva theorizes that each particle that hit the screen on a double slit experiment appears at both the slits simultaneously prior to reaching the screen. This view contrasts with what physicists believe to date. They believe that particles come thorough one of the slits in the Young’s experiment but not both. But particles coming through individual slits cannot explain the bright and dark fringe pattern forming on the screen. Therefore to account for the fringe pattern they theorize that particles behave like waves. However this so called wave property cannot be inferred when only a single particle is fired through the double slit, which results in a single dot on the screen and not a fringe pattern.
In the case of the double-slit experiment, quantum physics dictates that at the level of the slits, a particle is in a superposition of states corresponding to the position of the two slits. The particle is in this superposition as long as it is not disturbed. Placing a screen causes to collapse the superposition into one single state (position). Dr. de Silva interprets the superposition of positional states to mean that the particle actually exists at multiple positions prior to striking the screen. Using the super-positional states quantum physics can predict the probability of finding the particle at the screen or anywhere else between the screen and the double slits. The fringe pattern merely corresponds to the probability of finding the particle at various points of the screen. Dark fringes are where there is a zero probability of finding the particle and bright fringes are where there is higher probability of finding the particle. According to this interpretation, there is no interference of sort taking place as there are no waves to be considered. Why there is only a dot on the screen when a single electron is fired through the double slit is simply because the superposition of positional states collapses into one single position at the screen.
To prove that quantum particles do not have wave properties, Dr. de Silva designed an ingenious yet a simple experiment using a laser beam and double slit apparatus. Here, a series of aluminum sheets are placed along the zero probability positions as predicted by quantum physics, between the slits and the screen. Since light cannot penetrate aluminum sheets, no interference pattern should form on the screen if light behaved like a wave. On the other hand if light behaved as quantum particles, placing aluminum sheets at zero probability positions should not affect the fringe pattern since there is no particle present at those positions to interact with the sheet. The experiment was carefully set up by his student, Suraj Chandana. When the laser was turned on, the fringe pattern appeared on the screen as they had expected confirming the hypothesis that light consists of particles that did not have wave properties.
Physicists had to artificially attach a wave property to quantum particles to explain the fringe pattern in the Young’s experiment because they did not think that the superposition of positional states meant particles were at both the slits at the same time. According to the Copenhagen interpretation of quantum mechanics formulated by Niels Bohr and others, nothing can be said about the superposition of positional states before a measurement is made; it is the act of measurement that creates the knowledge of the position of the particle. According to Dr. de Silva’s interpretation or Vidyalankara interpretation as he prefers to call it, a particle actually exist at number of positions in superposition until the superposition is disturbed by an observer. Western physicists could not have considered this possibility since according to the Aristotelian logic a particle is either here or not here. But for people of many eastern cultures it is not a problem to believe that a particle can be at multiple locations at the same time, as they can relate to certain deities and supernatural beings that can manifest at different places at the same time. Today, the existence of such superposition of states is not just a legend but is supported by experiments. In 1996 Monroe and his colleagues had demonstrated the simultaneous existence of two spin states of Beryllium cation. Since then similar experiments have been carried out by others to prove the existence of superposition of states.
The Vidyalankara interpretation also resolves other paradoxes in quantum physics such as the Schrödinger's cat, the results of “which way” experiment and the Wheeler’s delayed choice experiment. For long physicists have been forced to understand quantum physics using particle and wave properties which are essentially classical ideas. Dr. de Silva expels these and introduces a nature that is more akin to quantum physics. He has created a paradigm shift in the knowledge of quantum nature.

Devivaru, Arsenic and Science

The ITI that first refused to test for Arsenic in samples of water from Rajarata wells supplied by the University of Kelaniya has apparently carried out tests to find out whether Arsenic is present in samples of pesticides either collected by them or provided by some other government authority. According to the tests supposed to have been carried out at the ITI, Arsenic is present in two brands of pesticides out of about ten brands. These figures may be wrong as I have no direct access to the data revealed at a press conference held on Monday the thirteenth at the Ministry of Agriculture. The Minister of Agriculture has also said at the same press conference that Arsenic is found in small quantities in these two brands of pesticides, nevertheless he had taken action to stop distribution of the same. We thank the Minister for his prompt action and also the ITI for apparently carrying out the tests without giving in flimsy excuses. However it is said that later the Minister had stated that there was a conspiracy against cultivation of rice in this country, and appears to have implied that our group is discouraging the farmer by claiming that arsenic is present in pesticides. In this connection he could consult his cabinet colleague Mr. Wimal Weerasinghe whose associates are spearheading a campaign against what they call “paan thrusthavadya” (bread terrorism), on whose side our group is in this campaign.

The Minister of Agriculture should refrain from making these insinuations without finding out facts. We are not a group against cultivation of rice in this country and the Minister has to be reminded that some students and teachers of the Faculty of Science of the University of Kelaniya have already cultivated a paddy field in Kirimetiyagara close to Kadawatha, without using any agrochemicals. It is now in the fourth “kanna” and we invite the Minister to visit our “kumbura” with his officials in order to learn a few things about “hela govikama”. It has to be emphasized that what we practice is not carbonic farming or green farming or anything that we have copied from the west, but “govikama” we had had in this country before the westerners, especially the English ruined it and then introduced so called scientific farming. Even in “govikama” we were guided by “samyak drshtika devivaru” who instructed on various aspects of “hela govikama”.

The group at Kelaniya is happy and feel vindicated as at least two brands of pesticides have been tested positive for Arsenic. If not for the experiments carried out at the University of Kelaniya, nobody would have suspected of Arsenic in pesticides, and the particular brands of pesticides would have been still available in the market. It was the group at Kelaniya that investigates into the Rajarata Chronic Kidney Disease first came out with the fact that Arsenic is present in at least in the samples of pesticides, and the samples of water from Rajarata areas collected by them. Prior to that no Chemist in Sri Lanka to my knowledge had claimed that Arsenic was present in at least some of the pesticides used in Sri Lanka in amounts exceeding what may be called the “safe limits”.

The merit (pina) in this regard should go to the “samyak drshtika devivaru” who first told that Arsenic is present in Rajarata drinking water and later revealed to us that Arsenic which is not found naturally in Sri Lanka has found its way to the wells and the wewas in Rajarata through Agrochemicals. It was this information that led us to test for Arsenic in pesticides, and it has to be mentioned that all the samples we had collected from various areas were contaminated with Arsenic.

In this connection I must mention again that though we obtained our knowledge of Arsenic in pesticides and drinking water in Rajarata from the “samyak drshtika devivaru” we never wanted the others to believe us simply on that information. We got the idea from the “samyak drshtika devivaru” but in order to convince those who had been trained in the western tradition we tested for Arsenic in water, soil, agrochemicals etc., in the laboratories of the Faculty of Science at the University of Kelaniya, using standard procedures in western Chemistry. In this regard I must again bring to the notice of the general public that when we were without a method in standard western chemistry to test for Arsenic in hard water (kivula) it was again the “samyak drshtika devivaru” who helped us indicating a method. The test was carried out in the laboratories with success.

The question may be asked as to the differences in the results we had obtained and that of ITI and other government “recognized” or accredited laboratories. While we had tested positive for Arsenic an all our samples, including those provided by Sri Lankan Customs, the government institutes have apparently found Arsenic only in two samples of pesticides. Now I do not claim to be a Chemist western or otherwise, even in my wildest dreams having failed in Chemistry at the University Entrance Examination as well as the GSQ (first year qualifying) examination at the University of Ceylon. I have only a pass in Chemistry at the GCE (OL) examination and even that “knowledge” is more than fifty years old. However, I am told by learned Chemists at the University that it is difficult to test for Arsenic in the laboratories at least for two reasons.

Firstly the Arsenic contaminated material has to be “digested” to get rid of various organic substances found in the sample, as otherwise the Atomic Absorption Spectrophotometer would not indicate the presence of Arsenic. Thus “digesting” has to be carried out taking extra precautions before the sample is tested. The second factor is that Arsenic is very sensitive to heat and the temperatures have to be controlled in the process of “digesting”. Arsenic apparently has a boiling point lower than the melting point and sublimation takes place and arsenic would vanish into air unless the correct temperatures are maintained. Our western Chemists have been very careful in taking all the precautions in carrying out the tests for Arsenic.

These may be the reasons rather than conspiracies that have led us to find Arsenic in our samples when the others have not been successful. We are prepared to open our laboratories for the Minister of Agriculture and the other concerned officials and invite them to be present when we test for Arsenic and we would invite the customs to provide the samples. On the other hand we would request the Minister to give us an opportunity to be present in the laboratories of the government institutions that carry out tests for Arsenic. While our people are dying in Rajarata we should not get involved in a game of conspiracies and counter conspiracies, and get together to help the Rajarata farmers as well as others to live a healthy life.
