Xenobiotic compounds are man made chemicals that are present in the environment at higher concentration.

The literature review presents data on the effect of organic and inorganic compounds the so-called main xenobiotics lead mercury on children and adolescents. Xenobiotic is a term used to describe chemical substances that are foreign to animal life and thus includes such examples as plant constituents drugs pesticides cosmetics flavorings fragrances food additives industrial chemicals and environmental pollutants. A pharmacologically endocrinologically or toxicologically active substance not endogenously produced and therefore foreign to an organism.

Most pharmacological agents are lipophilic and their elimination from the body is facilitated by enzymatic modifications to render them more hydrophilic. Certain xenobiotics are very toxic eg cyanide and some xenobiotics are not so much toxic even sufficient amounts of these are administered. Before proceeding along these lines of thought it is important to point out that the.

Xenobiotics are foreign chemical substances reported in an organism which do not occur naturally or normally in that targeted organism. The toxic effects of xenobiotics cover the wide spectrum. The majority of metabolic activity within the cell necessitates the presence of energy cofactors and enzymes.

Xenobiotics are chemicals that an organism is exposed to that are not part of its regular metabolism. GC methods need compounds that are volatile or semi-volatile such as toluene xylene and. Xenobiotics in animals include substances produced by the organism as well as substances accumulated by the organism from its environment.

Xenobiotics can be natural substances occurring in plants other animals or the environment. Several differences in the biotrans formation of xenobiotics between animals and plants have been suggested. This discrimination is artificial however since it has become apparent that while endobiotic metabolizing enzymes can also metabolize drugs and other foreign compounds xenobiotic metabolizing enzyme systems play a role in normal endogenous metabolism.

Sahar Jamialahmadi Studied Biology 3 y. These are either not produced naturally or are. Chromatographic analysis of xenobiotics are used for separation and determination of compounds with similar chemical structures in the air ground in surface water sludge soil matrices food and food products and in human and veterinary health care.
