... Polycyclic aromatic hydrocarbons (PAHs) and metals are toxic to animals, plants and microorganisms. Both these groups of contaminants coexist in the industrialized environments. Therefore, it is important to study the mixture toxicity of such pollutants on biological systems. In the present...

... in these sediments are expressed as parts per million (ppm) of Arochlor 1254. Values for selected congeners have also been determined. The development of these materials, as well as work underway on the development of a set of five sediment reference materials for polycyclic aromatic hydrocarbon (PAH) determination...

... A methodology has been developed for measurement of aerobic rates of microbial transformation of polycyclic aromatic hydrocarbons (PAH) in sediment samples. Individual 14 C-labeled PAH are added to sediment aliquots in sealed vials containing potassium hydroxide (KOH) traps. Vials containing...
