Distribución de plaguicidas organoclorados (OCPs) en sedimentos costeros de América Latina

Abstract

Organochlorine pesticides (OCPs) are compounds that have been forbidden in most of the World countries for been highly toxic and persistent. Due to their intrinsic characteristics, even today, they can be found in almost any environment. In this work it was aimed to analyze their distribution in Latin American coastal sediments, at Atlantic and Pacific oceans, through the analysis of thirty three scientific publications that characterized a total of fifty five sites. It was observed that general concentrations depended of the own characteristics of each site, being larger closer to big cities or intensive agricultural fields, as well as semi-closed environments with larger rates of water permanence and consequently larger influence from the continent. Likewise it was observed that the composed addition of OCPs was similar among sites located in the same country or region. Keywords: Organochlorine pesticides, sediments, coasts, Latin America, composition.
