    This study examines the direct and indirect effects of atrazine on two grazer species— Physa acuta and Ancylus fluviatilis —as assessed by changes in mortality rates, biomass, searching behaviour and histological properties. No direct effects were observed in the acute toxicity test (48 h) with , , 2, 10 and 20 mg l−1 of atrazine. A chronic toxicity test (18 days) performed in six.

Concentrations of chlorophenoxy acid (CPH) and s-triazine herbicides were determined in the sediments of five salt marsh sites on the Essex coast (UK).The degree of contamination, in the ng g −1 range, was related to herbicide usage in the adjacent catchment, the duration between herbicide application and sampling and the mobility and persistence of individual herbicides.

Results were less conclusive in the field but the trend was toward a lower level of similarity. Based on the least effect level of atrazine to diatoms, the maximum safe level for atrazine in the salt marsh is 10 ppb.

Furthermore, atrazine must be leaving this region in the top layer by some diffusion-like mechanism. To achieve steady state, atrazine concentrations in the outflow surface water need to be µg/L, but there is no evidence that supports this estimate.
