[edit] Dear

Dear Editor,

I want to propose a new definition of "Xenobiotics" as the definitions available are not complete.

Xenobiotics are compound that are resistant to biodegradation. They may be synthetic eg. plastics and pesticides or naturally occurring eg. Poly Aromatic Hydrocarbons (PAHs) and some fractions of crude oil and coal. It is believed that there are undiscovered microorganisms that can bioremediate the different complex and resistant xenobiotics found on the earth.

Not all xenobiotics are resistant to degradation. Substances such as chlorodinitrobenzene decay very rapidly, as do epoxy compounds. These are reactive xenobiotics. TimVickers 22:09, 9 March 2007 (UTC)
