According to WHO, over
1,000 pesticides have been used so far, with many different chemical compositions. In particular, organochlorines (OCPs) and polychlorinated
biphenyls (PCBs) has been attracting scientists in the world, due to their high
bio-accumulation and toxicity for human, wild-life species and adverse impacts
on eco-systems.
Owing to their high
stability, PCBs and OCPs compounds are accumulated in different marine
environments (sediments, waters, organisms, ...) and
they were mostly derived from continents. Therefore, investigation and
monitoring programs have been implemented by world-wide scientific institutes,
in order to evaluate the distribution and accumulation of these organic
compounds in sediments of coastal areas.
This article is aimed to set forth distribution chacacteristics of PCBs
and OCPs compounds in sediments of the Mỹ Thạnh estuarine areas,
then to suggest reasonable recommendations and solutions for preventing
environmental pollution and negative impacts on ecosystems. This is a part of
outcomes of the Project: “Survey and assessment of mineral resource potential
in coastal areas of
