Environmental toxicology is a branch of science that studies how various chemicals affect the environment, specifically wildlife and ecosystems. Toxicology, in general, studies how foreign chemicals affect the human body, this particular branch (environmental toxicology) has researchers studying the adverse effects of pollution to the overall state of ecosystems, fauna, flora, and human health as well.
Toxicologists in the environmental field usually take soil, air, and water samples for study just as much as an ordinary toxicologist performs biopsies to ascertain the effect of a certain chemical on a sample body organ or tissue. The results of their analysis help them identify pollutants and predict danger levels in the ecosystem where they took the sample.
Specialists can also opt to focus their research on one ecosystem in particular. For instance, he may study the effects of factory smoke on the health and behavior of animals in nearby forests, or the effects of an oil spill on marine life, and many more.
Perhaps one of the most common uses of the findings of an environmental toxicologist is for government analysis and enactment of legislation that seeks to protect Mother Nature. Furthermore, environmental lawyers consider the findings of these experts as evidence for litigating companies and individuals who violate the environmental laws.
