Sediments are depositories of toxic substances such as organochlorine pesticides and there is a global need for their removal in contaminated environments. Studies that combine contaminated sediments and phytoremediation are relatively recent and their number has been increasing. This work aimed to investigate whether salt marsh plants (sea club-rush Scirpus maritimus, sea rush Juncus maritimus and...
Data on levels of persistent organochlorine pesticides (OCPs) that exhibit potentially harmful effects to the environment all over the Portuguese coastal sediments were scarce. Therefore, in 2007–2008 12 OCPs were surveyed in surface sediments from 11 coastal sites (estuarine or lagoonal) covering north, centre and south areas of Portugal. Analyzes were performed using a previously validated method,...
Determination of organochlorine pesticides (OCPs) in sediments implicates extraction of these compounds from the matrix, which is difficult owing to strong interaction among OCPs and different constituents of the sediments, particularly organic content. The method here described is a combination of microwave assisted extraction (MAE), headspace solid-phase microextraction (HS-SPME) and gas chromatography–mass...
