organic compound

In physics, a material that contains carbon and hydrogen and usually other elements such as nitrogen, sulfur and oxygen. Organic compounds can be found in nature or they can be synthesized in the laboratory. An organic substance is not the same as a "natural" substance. A natural material means that it is essentially the same as it was found in nature, but "organic" means that it is carbon based.

A printed circuit board is an example of an organic substrate because the laminate material is made of glass fibers in an epoxy, and epoxies are carbon based (see FR4). See organic chemistry.

Chemist Gordon Gribble, who studies natural halogenated compounds at Dartmouth College in Hanover, N.H., calls the study "wonderfully exciting." The same technique could be used to assign a natural or synthetic origin to other organic chemicals that accumulate in food chains, he says.
Predicting transfer of inorganic chemicals via breast milk presents unique challenges that were not previously encountered in working with organic chemicals. Although the levels of organic compounds passed into the milk are based primarily on partitioning, both ionic compounds and metals are usually transferred into the mammary tissue via some type of transport process.
