Understanding Environmental Toxicology

Classified under the broad wing of environmental science, environmental toxicology is a discipline studying the direct and indirect effects of ecological pollution to human life, particularly health. It primarily deals with five sub-fields.


The atmosphere. For the past 40 years, environmental toxicology has focused a huge part of its efforts into studying the interaction of man-made pollutants with the atmosphere, and how such interactions can provoke an torrent of disadvantages to the Earth’s inhabitants.

Water sources. Continuous research was also conducted to determine the possible negative effects of excess, runoff nutrients to water sources throughout the world. Valuable nutrients, while highly beneficial in small amounts, are dangerous when concentrated highly than normal and can even damage an entire aquatic system.

Heavy metals. The Industrial Revolution has spewed out a significant amount of chemical pollution onto the Earth, including toxic metals that may find its way into food and potable water supplies.

DNA mutations. The effect of environmental toxins on living DNA is also examined, in order to determine if mutations can occur upon exposure.

The Big C. The study of the relation between the developments of cancers like leukemia, lung cancer, melanoma, and lymphomas are also covered by environmental toxicology. Environmental toxicologists investigate these incidences and how intensely exposed an individual/groups of cancer patients are to several substances.
