The most common non-toxic organic compounds include materials of plant and animal origin such as proteins, amino acids, sugars, fats; compounds containing N, P. Toxic organic compounds include compounds of alkyl phenols, chloro-benzenes. Metals such as: Zn, Pb, Cu, Cd, Ni, Cr, Hg, As. Some of these compounds can be toxic to humans and animals.
