Determination and fate of organic pollutants in the environment.
Different sample preparation methodologies were evaluated for the determination
of pollutants in different matrices. The methods investigated were chosen on the merits of
decreased sample preparation time and low toxic solvent consumption with the aim to
provide viable alternatives to more laborious methods, such as, Soxhlet extraction.
Techniques were developed to extract and quantify organic pollutants from contaminated
soils and water.
The results from shake flask extraction of aged phenolic contaminated soils were
used in attempt to relate sorption to both the soil, and pollutant properties. This was to
help gain an understanding of the transport and fate of phenols in different environmental
situations. The partitioning (sorption/desorption) of radiolabelled phenols between
aqueous solution and soil was investigated using a modified shake flask technique. This
provides additional information which can be related to soil characteristics, hence
pertaining to the fate mechanisms involved for phenols in the environment. The results
from these investigations suggest that more than one factor contributes to the sorption of
phenols in soils.
