||The distribution and persistence of DDE and lindane added to the epilimnion of a thermally stratified, ultra-oligotrophic flooded limestone quarry were studied. The quarry was treated with a single sub-lethal dose of each compound at a concentration of 200 pptr in the epilimnion or 50 pptr based on the entire water mass. An adjacent quarry was used as a control. Water, bottom sediments, limestone rock slabs, zooplankton, and fish were periodically analyzed. Dissolved oxygen and temperature profiles were also monitored. Results indicated that persistence of the pesticides may be primarily controlled by adsorption onto suspended particles.
