Abstract |
"Physico-chemical speciation" is presented as a concept to describe the environmental chemistry of organic compounds in aquatic systems, using polycyclic aromatic hydrocarbons as an example. Survey data and experimental results are reported which demonstrate the presence of different physico-chemical species of PAH in the Tamar Estuary, UK. The degree, and hence chemistry of binding of PAH to particulates in the Tamar is shown to be incompatible with current sorption modeling techniques. This finding has extensive repercussions on prediction of the aquatic chemistry of PAH, including availibility of the compounds for fates such as photo-oxidation and biological uptake/toxicity. |
