A skull and crossbones might be a suitable symbol for this major. (That鈥檚 one way to explain that tattoo . . . .) Toxicology basically tackles issues involved with various types of poisons. According to the University of Arizona, toxicology is 鈥渢he study of how chemical and physical agents adversely affect living organisms.鈥� If you choose to major in toxicology, you鈥檒l learn about these chemical and physical agents鈥攚here they lurk in the environment, how humans are exposed to them, and the problems they create in different arenas, like the clinical, industrial, and legal fields. This includes the study of how these agents enter the body, what happens to them once they鈥檙e inside, and how they can damage cells, tissues, and organs. You鈥檒l also learn how toxicants pose a threat to our animal friends, along with examining poisons found in plants and foods, such as pesticides, food additives, and waste from industry. You鈥檒l learn how to test food and water for unhealthy or dangerous levels of toxicants, and you鈥檒l gain the skills necessary to counteract their effects or eliminate them altogether.

Toxicology is an important field for obvious reasons, and advancements can be rapid. Your course work might involve studying what sorts of environmental agents lead to cancer, or the effects these agents have on the neurosystem. You might engage in a study of chemical genomics and examine how toxicants affect gene expression鈥攁 hot topic these days. Or you might immerse yourself in drug research and development.

Your studies will go beyond the toxic agents themselves, of course. You鈥檒l study safety procedures necessary to implement and adhere to during research, and you鈥檒l learn how to collect and analyze data from the experiments you perform. Legal aspects of chemical use by industries and individuals will also be hashed out. And you鈥檒l gain experience with research through laboratory work and, perhaps, an internship.
