A study conducted by the Centre for Science and Environment found 'very high' levels of pesticide residues in human blood samples that were taken from Punjab villagers.
Blood samples collected from four villages in Punjab showed 15 to 605 times higher residues of certain persistent organochlorine pesticides as compared to samples of people in the United States.
The 'cocktail' contained six to 13 pesticides in the samples, the study said.
The average levels of monocrotophos in the blood samples (0.095 ppm) were found to be four times higher than the short-term exposure limit for humans set by the World Health Organisation and the Food and Agricultural Organisation, the report, released in Chandigarh, said on Tuesday.
The CSE study calls for urgent action to regulate pesticides use. It calls for action to monitor human bodies -- a biomonitoring programme -- to ensure that this chemical invasion is stopped.
The study tested 20 randomly selected blood samples from four villages -- Mahi Nangal, Jajjal and Balloh in Bhatinda district and Dher in Ropar district. Each sample was tested using an internationally accepted methodology, the report said.
The samples were compared with those collected from people in the US and were tested by the United States Centre for Disease Control and Prevention. The results were published in its report of 2003, it said.
