PESTAB. Analyses of water soluble heavy metal ions, lead and mercury, were performed on water samples collected from the North Mississippi River. Results indicated that p,p'-DDT and aldrin were present in fairly high concentrations, especially in the L. Tallahatchie and Yazoo Rivers. In the 10 samples taken, the range of concentrations for aldrin ran from 0.01 to 0.49 ng/l, for heptachlor from non-detectable to 0.18 ng/l; for lindane from 0.02 to 0.16 ng/l, and for p,p'-DDT from 2.73 to 12.31 ng/l. These levels may be due to the extensive use of pesticides in this agricultural area for the protection of cotton, soybean, and corn crops.
