Occurrence And Concentrations Of Polychlorinated Dibenzo-p-dioxins (pcdds) And Polychlorinated Dibenzofurans (pcdfs) In Coastal Marine Sediments In Kuwait

摘要

Since the discovery of oil in the Arabian Gulf region the number of heavy industries, especially oil-based industries, like refineries, have increased exponentially (Fowler, 2002). Most of these major industries, out of convenience, are located along the coastline. As a result a variety of chemicals including heavy metals, oil and petroleum-related compounds, nutrients, and halogenated organ-ics have been introduced into coastal marine sediments (Beg et al., 2003; Gevao et al., 2006a,b; Readman et al., 1992). Dioxins, like other anthropogenic compounds, enter the aquatic environment from a variety of sources including (i) direct deposition from the atmosphere, (ii) runoff from land, and (iii) directly from industrial and wastewater treatment plant discharges (Broman et al., 1992; Dunn and Stich, 1976).
