The effect of exposure to certain pesticides "rivalled" that of smoking in increasing cancer risk in farmers, according to a US study that compiled 69 such chemicals, including four commonly used in India.
Researchers found that for three types of cancer -- non-Hodgkin's lymphoma, leukemia and bladder cancer -- the effects of pesticide exposure were "more pronounced" than those of smoking, widely acknowledged as a cancer risk factor.
"We present a list of major pesticide contributors for some specific cancers but we highlight strongly that it is the combination of all of them and not just a single one that matters," senior author Isain Zapata, an associate professor at the Rocky Vista University, US, said.
The list, compiled in the study published in the journal Frontiers in Cancer Control and Society, features 69 pesticides, including 2,4-D, Acephate, Metolachlor, Methomyl. These four are among many commonly used in India to combat various threats to crop yields, such as insects an
