Pagination or Media Count:
Samples of soil, plants, fish, and algae were collected from sites peripheral to, and within areas where termite and fire ant control insecticides were repeatedly applied. These samples were then analyzed for insecticide residues by electron capture and thin layer chromatographic methods. Aldrin and dieldrin residues were found in soils in areas where the insecticides were applied. Occasional low levels 0.05 to 0.28 ppm of aldrin and dieldrin were found in mud samples taken from two nearby creeks. Flounder caught in these creeks were free from detectable aldrin and dieldrin, but DDT, DDD, and DDE were found. Water from wells in the insecticde application area and from nearby creeks contained no detectable aldrin, dieldrin, or DDT.
