Toxicology

Toxicology is the study of the impacts of chemicals (as drugs, food additives and environmental contaminants) on both humans and the environment.   The Industrial Revolution of the mid-19th century released many naturally-occurring chemicals into the environment in unprecedented amounts and resulted in the production of thousands of new substances. Results from toxicity studies support drug, food and industrial chemical regulation, remediation, and production.  Although past practices focused on exposures of high doses to single chemicals practitioners of the science have recognized the importance of evaluating the impacts of low doses, and chemical mixtures as more sensitive biochemical and genomic methods are incorporated into chemical evaluation and regulation.

Carbon monoxide Last Updated on 2014-01-16 09:44:12 Carbon monoxide (CO), also referred to as carbonous oxide, is a colorless, odorless, and tasteless gas that is slightly lighter than air. Exposure to high levels of carbon monoxide is extremely toxic to humans and animals.  Conversely, small amounts of carbon monoxide are produced in normal animal metabolism and it is thought to have some normal biological functions. Carbon monoxide consists of one carbon atom and one oxygen atom. It is the simplest member of the class of inorganic compounds known as oxocarbons which includes carbon dioxide (CO2), carbon suboxide (C3O2), mellitic anhydride (C12O9) and many others. When combined with a metal (i.e. an organometallic complex), the carbon monoxide is a ligand called carbonyl: for example, in nickel carbonyl with the formula Ni(CO)4. Carbon monoxide is produced by the partial combustion of carbon-containing substances. It is produced... More »
