Fig. 1. Relationship between the total endosulfan (sum concentration of - and ß-endosulfan plus endosulfan sulfate) and endosulfan sulfate in the overlying water column, with total endosulfan concentrations in the bottom sediment. Both regressions for total endosulfan and endosulfan sulfate were significant (P < 0.01, R² > 0.98) and violated no linear assumptions.
