Organochlorine pesticides show biological toxicity and their degradation typically takes
many years. Previous studies of agrochemical-contaminated areas have mainly focused on …

Persistent organic pollutants (POPs) present in water may be bioconcentrated in
phytoplankton and further transferred into higher trophic levels. In the present study …

Although organochlorine pesticides (OCPs) have been banned for more than three
decades, their concentrations have only decreased gradually. This may be largely …
