THE MEASUREMENT OF ATMOSPHERIC CONCENTRATIONS AND DEPOSITION OF SEMIVOLATILE ORGANIC-COMPOUNDS

A physical description of semi-volatile organic compounds (SVOCs) is g iven, both in terms of their characteristic nature in the atmosphere a nd 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 associa ted problems have also been reviewed for measurements of atmospheric d eposition. A summary has been given of the requirements necessary for a full assessment of atmospheric SVOCs and their deposition.
