| Dichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichloroethylene (DDE), and dichlorodiphenyldichloroethane (DDD) are of environmental concern because their bioaccumulation and biomagnification through the food chain pose a risk to the ecosystem as well as human health. These chemicals are persistent in soils, where they are slowly broken down by microorganisms and/or taken up by plants. In this research, dominant plant species from four previously studied sites, where DDT, DDE, and DDD were commonly found, will be analyzed for their uptake capacity of such contaminants. Stir bar sorptive extraction (SBSE) will be used for sample preparation, and thermal desorption coupled with gas chromatography/mass spectroscopy (GC/MS) will be employed for chemical analysis. Results from this research will contribute to a better understanding of the mechanisms of plant uptake of organic pollutants. The quantification of plant uptake capacity will provide valuable information for phytoremediation of soils contaminated with DDT, DDE, DDD and other organic pollutants. |
