ln experiments with mammals, it has been
found that various insecticides interact with
each other in biological tissue. For example,
when aldrin, dieldrin, endrin, heptachlor, or
chlordane are fed to animals in coniunction
with BDT, the amount of these insecticides
that is stored (mainly in the liver) is greatly reduced. A number of drugs, such as the barbituates, are also more quickly metabolized
(broken down and passed through the body)
when a‘dministered with DDT [9].
