Summary of total chlordane, total DDT, dieldrin, heptachlor epoxide, DDD, DDE, and total PCB concentrations in fish tissue (carp or white suckers) and bed sediment from the Lower Illinois River Basin, June-Oct. 1996-97. DDD and DDE are breakdown products of DDT

[mg/kg, micrograms per kilogram (equivalent to parts per billion); na, not applicable]
