Aquatic toxicology

Aquatic toxicology is the study of how chemicals in the environment can harm creatures that live in water, like fish and other animals. These chemicals can come from many sources including factories and agriculture. When chemicals get into the water, they can be toxic, which means they are harmful to the creatures that live there. The goal of aquatic toxicology is to figure out how to make sure that the creatures in the water stay healthy and safe.
