Residues, Soils, and Plants
Since the mîd-1940's there has been a renewed and heightened interest in questions involving residues of agricultural chemicals in soil. This has occurred because agriculture has been recently supplied with a number of entirely new synthetic compounds for pest control, of largely unknown stability and toxicity to plants when present in the soil. During the Second World War, when DDT first came ...
متن کاملSummary of well water sampling in California to detect pesticide residues resulting from nonpoint-source applications.
This report summarizes well sampling protocols, data collection procedures, and analytical results for the presence of pesticides in ground water developed by the California Department of Pesticide Regulation (DPR). Specific well sampling protocols were developed to meet regulatory mandates of the Pesticide Contamination Prevention Act (PCPA) of 1986 and to provide further understanding of the ...
