Agricultural Chemicals in Surface Runoff, Ground Water, and Soil: I. Endrin1

Endrin (1,2,3,4,10,10-hexachloro-6,7-epoxy-1,4, 4a,5,6,7,8,8aoctahydro-1,4-endo, endo-5,8-dimethanonapthalene) was surface applied at a rate of 0.337 kg/ha to sugarcane (Saccharum officinarum L.) plots instrumented to sample surface runoff and ground water. Runoff, ground water, and soil sampleswere collected over a 2-year period and analyzed for endrin. Only small amounts of endrin were lost annually in runoff (less than 0.2% of that applied), and little endrin accumulated in soil. Trace amounts of endrin appeared to move through soil in the plots but not through soil columns. A delay of 72 hours between application and rainfall decreased the amount of endrin in runoff, ground water, and soil.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
