Mr. Siri Pathirana,\u00a0 a Farmer from Malsiripura\u201d has responded (1st<\/sup> February,\u00a0\u00a0 Island\u201d) to my article\u00a0 (Island, 24 January).\u00a0 Mr. Pathirana\u00a0 recounts his memories about the poisoning of fish in a paddy field after the application of pesticides some 60 years ago (note that the word pesticide\u201d includes herbicides, insecticides, fungicides etc., as used by the WHO).<\/p>\n

Mr. Pathirana states that:<\/p>\n

This pathetic, inhuman scenario was created by multi-national pesticide companies almost sixty years ago. Most of the fauna gradually disappeared from the immediate vicinity of the paddy fields. If we use an alternative method instead of chemical pesticides, we would feel much healthier and happier as humans\u201d.<\/p>\n

It is possible that young Mr. Pathirana had\u00a0 observed the consequences of DDT that was enthusiastically introduced to Sri Lanka (and the rest of the world). It was successfully used to combat a Malaria epidemic that had brought the country to its knees. It was not a case of multinationals malevolently baiting the public. The government, the agricultural and health scientists, and the public welcomed these new pesticides as they were effective, cheap and virtually non-toxic to humans. Their long-term consequences were NOT known in the 1950s. For instance, three parts per trillion of DDT in the water can accumulate in higher organisms to, e.g.,\u00a0 0.5 parts per million in minnows, 2 ppm in cows,\u00a0 and even more in mother’s milk at the top of the food chain.<\/p>\n

Mother’s milk had 10-20 times more DDT than cow’s milk, resulting in the 1970s push for baby formulas instead of breast feeding.\u00a0 DDT was banned in 1974, but the WHO now regards it\u00a0 safe for domestic use against mosquitoes and other pests, but NOT for agriculture.\u00a0 In the 1960s, 2-3 kg of DDT per hectare were applied, compared to modern pesticides using only a mere 10g\/hectare. Modern pesticides are designed to quickly degrade and become harmless.<\/p>\n

However, DDT was\u00a0 in many ways BETTER and SAFER than the pesticides used prior to DDT. Salts of arsenic, fluorine or plant products such as nicotine, pyrethrum and rotenone were used in the plantation sector; fungicides used mercury, copper or sulphur; herbicides used petroleum oils,\u00a0 tar, sulphuric acid, some arsenites. These are truly dangerous to the environment, and toxic to humans. Dead fish were found even those days, after the application of such pre-War pesticides. But most small farmers did not use them as labour was cheap and\u00a0 land was available in plenty. Site rotation (e.g., in Chena cultivation) was available as an alternative for pest and soil fertility management. Farmers were happy with even a yield of one metric tonne of paddy per hectare. Some of these pesticides are still\u00a0 used\u00a0 in organic farming\u201d, in the mistaken belief that they are safer\u201d.<\/p>\n

During Mr. Pathirana’s\u00a0 childhood, and well into the 1980s, extremely toxic\u00a0 red lead (rathu kudu\u201d) was used in Sri Lanka in paints, added to cement for flooring, and used as an anti-rusting on railway bridges. Creosote was used on logs and railway sleepers. Ceylon Tobacco managers who sold a well-recognized cancer product were held in high esteem instead of being thrown in jail. Buses and cars belching fumes full of particulate matter, from partially burnt fuel adulterated with Kerosene engulfed the road system and houses. These toxins, present in abundance are ignored, and the parts per billion glyphosate is targeted by the Toxin-Free\u201d claimants. The bio-accumulation effect of glyphosate is negligible in comparison to DDT. Meanwhile politicians are planning to set up more and more coal plants (notorious for emitting pollutants) for power generation; Venerable Ratana has not voiced opposition to it.<\/p>\n

When Mr. Pathirana finds dead fish in the water from pesticide applications, we see a case of ACUTE toxicity\u201d due to misuse of excessive application of pesticides, or due to a chemical spill\u201d. However, what is relevant for the environment is CHRONIC toxicity. That is, toxicity arising from the ingestion of very small amounts of toxins for a long period, leading to\u00a0 Chronic diseases\u201d. Previously no globally accepted standards on the daily admissible intake (DAI) of various pesticides existed.<\/p>\n

Today, the DAI values are well established. The WHO-FAO Joint Meeting on Pesticide Residues (JMPR) regularly updates the DAI for\u00a0 approved pesticides.\u00a0 The claim that multinational agricultural companies work hard to sell their products is true, but the regulatory agencies have been more than vigilant. Even stricter maximum allowed limits (MALs) of pesticides\u00a0 are enforced as good farming practice. A recent scary news item in Sri Lankan newspapers claimed (falsely) that common herbs\u00a0 like Gotukola\u201d and Mukunuwenna\u201d are full of\u00a0 pesticide residues. The reporter had confused the MALs with the DAI values. An article that appeared in the Sri Lanka Medical Association Journal (August 2018) by Dr. Gunatilleke shows that even medical doctors may confuse MALs with DAIs and cry wolf\u201d, claiming that parts per billion amounts of glyphosate are dangerous.\u00a0 The toxin levels in Sri Lankan farm produce are well below danger levels. Eating\u00a0 several kilos of `Gotukola’ daily, for tens of\u00a0 years is needed to cause chronic toxicity on eating local vegetables (see Daily News. 11-Nov-2018,\u00a0 http:\/\/www.dailynews.lk\/2018\/11\/07\/features\/167704\/toxic-cocktail-myth-and-truth<\/a>).<\/p>\n

Long-term studies are needed to establish ADIs, to assess\u00a0 the cumulative effect of ingesting small amounts of the pesticides daily. Glyphosate inclusive of adjuvants\u00a0 was tested continuously for 23 years on a 90,000 sample of farmers, and the results were released in November 2017. This expensive giant health study was conducted by the US Health department and found no increase in the health risks of the sample compared to the health of non-farmers.<\/p>\n

Nevertheless, Mr. Pathirana says that \u00a0 farmers need to be saved <\/strong><\/u><\/p>\n

(a) From the ‘Scientists’ and ‘Professors’ who are paid by the pesticide companies\u201d<\/u><\/strong>.<\/u><\/p>\n

The US government conducted and funded the 23-year\u00a0 study for transparency. There are some corrupt scientists and corrupt professors, just as\u00a0 in every walk of life. In Sri Lanka, politically ambitious scientists claimed that the Kidney Disease known as CKDu found in the Rajarata is caused by glyphosate and arsenic from agrochemicals. Having no evidence, they claimed that God Natha had revealed all this.\u00a0 Meanwhile, a team of scientists and professors sponsored by the WHO and the government showed that the water, soil and the food in the Rajarata had NO significant amounts of glyphosate or arsenic. This was independently confirmed by other teams of scientists.<\/p>\n

The scientists who claimed that CKDu was caused by agrochemicals had their own agrochemicals to sell. They had their own companies, underwritten by SEMA, an organ created\u00a0 by politicians. Their agrochemicals had NOT been tested and proven safe.\u00a0 So, Mr. Pathirana’s concern (a) applies to the SEMA scientists and politicians, and not to the scientists who upheld the agriculture industry with a proven record of\u00a0 safety as well as delivering the food to a population that has tripled since\u00a0 Pathirana’s boyhood.<\/p>\n

(b) From the corrupt politicians who promote the use of pesticides despite the adverse effects visible in rural farming.<\/u><\/strong><\/p>\n

Mr. Pathirana alluded\u00a0 to his memories from 60 years ago as the adverse effect visible in rural farming. Is that the ONLY evidence he has ? We know that over use of phosphate fertilizers leads to algal blooms and such effects. But these pale\u00a0 in comparison with the diesel and petroleum toxins belched out on the roads everyday, compounded with plastic garbage burnt on every roadside.<\/p>\n

Mr. Pathirana thinks that our paddy fields are full of toxins. Large numbers of egrets (‘kokku’) and other birds\u00a0 collect to eat the earthworms and other bugs that get turned up by the farmer’s plough. If the soil is toxic, these organisms should be dead.\u00a0 In fact, the soil is rich in worms and micro-organisms, fertile, and yields\u00a0\u00a0 bountiful harvests. Sri Lankan rice or Sri Lankan Tea is not contaminated by toxins, as claimed by various anti-national organizations that are attempting to discredit the nation’s exports.<\/p>\n

We would all be happier if the tea plantations were pristine forest, even taking an economic loss.\u00a0 However, tea\u00a0 is our last defense against the conversion of the hills\u00a0 into housing and hotels enmeshed in asphalt and concrete\u00a0 if tea planting were made uneconomical by SEMA’s maverick agriculture.<\/p>\n

The banning of glyphosate destroyed the Maize plantations.\u00a0 Farmer resorted to smuggled glyphosate of Indian origin containing the worm. Now Ven. Ratana wants to kill the Senaa caterpillar using an\u00a0 untested\u00a0 Neem (Kohomba) pesticide. Such products will\u00a0 also kill the caterpillars of beneficial butterflies, moths, earthworms, and destroy bees\u00a0 essential to pollination.<\/p>\n

\"\"<\/p>\n

Kidney disease and Scientists investigating it.<\/u><\/p>\n

It should be emphasized that the kidney disease epidemic in the Rajarata has been politicized by Venerable Ratana and some political ambitious scientists who constitute a small fringe\u00a0 of the totality of scientists and Kidney specialists of Sri Lanka. Some among these fringe group of scientists have slandered the active researchers claiming that they are paid agents of multinationals, simply because they don’t accept the claim that the disease is caused by agrochemicals. Mr. Pathirana is also unfortunately repeating\u00a0 the cheap claim that our Sri Lankan scientists and professors, 95% of them, and the Members of the National Academy of Sciences, the Kidney specialists etc., are all shielding the agrochemical companies because they have been paid to keep mum.<\/p>\n

Studies of wells used by CKDu patients, as compared to wells in adjacent villages<\/p>\n

free of CKDu, show that endemic villages have fluoride and magnesium in the well<\/p>\n

water which is stagnant and unconnected with the water table of the lower lying agricultural water.<\/p>\n

Such stagnant well water from CKDu villages, when given to laboratory mice contract kidney injury similar to those of CKDu patients. All this research has been carried out by the Kidney Specialists of the Kandy hospital and various Peradeniya scientists working together as a research team known as “CERTKID”.<\/p>\n

These endemic villages are in areas which were never populated prior to the accelerated Mahaweli project. The Accelerated Mahaweli project\u00a0 settled people even in high-ground areas without much attention to the geology. People dug their household wells or tube wells\u00a0 for domestic water, and these were not tested for water quality.<\/p>\n

The domestic and farm animals in these endemic villages do not get CKDu because they do not drink well water, but drink from nearby water streams. If at all there were any agrochemical contamination, then it will be in such water streams.<\/p>\n

In general,\u00a0 ground water may be either too hard due to calcium and magnesium salts, or it may have various other problems with it, including contamination from human and geological sources.<\/p>\n

Mr. Pathirana as an individual is privileged to reject the Professors and Scientists\u00a0 regard them as crooks. He may embrace the monks he trusts, SEMA and the scientists in its pay, and also the occult God-Natha Media as his guides. But neither he, nor the government, should impose this on other farmers who have the right to be guided by the professionals of the department of agriculture and the crop research institutes, and by the medical scientists who have been conducting research on environmental diseases like CKDu.<\/p>\n
