Dr. Padeniya just tell me any drug that has no side effect. So is the solution to stop taking all drugs.
If your argument that even trace quantities of a substance that is not good for health should not be allowed just explain these two
1. Why do we have Afolotoxin percentage in all our coconut oils
2. Potable water (drinking water) of sri lanka Standard contains Ca and Mg quantities(these cause stones our bodies. and this creates hardness to water)
If you want I can give some more.
Kelaniya Uni did a research to prove fertilizer added Arsenic in North Central Province , (this is famous Lord Natha's dream reserch by Dr. Nalin (not a soil or chemistry exepert) with Pof Channa Jayasumana) This hypothesis could not be proved though research. You can ask him as he is state Minister of Health now!
Dr. Padeniya is a Medical Doctor who had specialized Neurologist and talk nonsense about Soil , chemistry , FTA, KDU, MCC etc
Next issue is do not rely on research which were not peer reviewed.
