Abstract

Atrazine is a chemical used to kill plants. It runs off agricultural fields into water systems and may have an effect on aquatic life. This study looked at periphyton – a group of very small organisms that aquatic snails eat. The researchers used test ponds to see how differ-ent concentrations of atrazine would affect the snails and their food source. They found that atrazine did not reduce or increase growth of periphyton. Without changes in periphyton, there were no changes in snail populations caused by atrazine.
