Table 4. Organic compounds detected in fish-tissue samples, Yellowstone River Basin, 1998
[All concentrations in micrograms per kilograms wet weight, unless expressed otherwise; mm, millimeter; g, gram;
<, less than; E, estimated concentration. Concentrations of total chlordane and total DDT are calculated values, and are listed as zero,
if all of the respective compounds are less than the reporting limit. Total chlordane includes cis-chlordane, trans-chlordane, trans-nonachlor,
and oxychlordane. Total DDT includes o,p´-DDD, p,p´-DDD, p,p´-DDE, and p,p´-DDT.]
