The measurement of atmospheric concentrations and deposition of semi-volatile organic compounds.

A physical description of semi-volatile organic compounds (SVOCs) is given, both in terms of their characteristic nature in the atmosphere and the processes which control their deposition. The currently adopted methods used to measure the atmospheric concentrations of SVOCs have been summarised, along with their shortcomings. Techniques and associated problems have also been reviewed for measurements of atmospheric deposition. A summary has been given of the requirements necessary for a full assessment of atmospheric SVOCs and their deposition.
