Toxic nitrophenols from the liquid phaase initroation of phenols

摘要

Aromatics with polar substituents such as phenol,benzoic acid,nitrophenols,nitrocresls and others have been found in concentratios in the ug L~-1 range in th Rhein-Ruhr area in western Germany and in urban Los Angeles rain (Hansen et al., 1991).Aqueous phase nitrotion of aromatics may lead to the production of harmful products.Several reports are available related to the toxicity of nitrophenols to orgnaisms.While there is ocnsiderable evidence for the occcurrenge of aromatic and nitroaromatic ocmpounds in clud and rainwater,different possibilities exist with regard to the origin of the later compounds.
