520 |a"Environment Canada, in co-operation with Agriculture Canada, is developing a pro-active or anticipatory programme to determine the environmental behaviour of pesticides and nitrates under Atlantic Canadian conditions. This approach is intended to provide interested parties with the needed protocols for evaluating the chemistry and fate of agrichemicals, particularly as they relate to the new guidelines for the registration of pesticides in Canada. Also, to determine under what agricultural practices particular pesticides and fertilizers can be applied without causing unacceptable contamination of groundwaters. Certain pesticides suspected of being soluble and persistent enough to contaminate groundwaters will be subjected to controlled field applications"--Executive Summary, page i.
