JARAMILLO, BEATRIZ E; MARRUGO, MARÍA PATRICIA  and  DUARTE, EDISSON. MONITORING OF ORGANOCHLORINE PESTICIDES RESIDUES IN SHRIMP (Penaeus vannamei) FROM THE COASTAL AREA OF CARTAGENA BAY COLOMBIA. Rev.Bio.Agro [online]. 2010, vol.8, n.2, pp.66-71. ISSN 1692-3561.

The utilization of organochlorine pesticides for pest control chemical has been of great interest on residue contamination from biológical organisms in the environment. Shrimp (Penaeus vannamei) samples were monitored as bioindicators for assessment of the water quality in coastal waters along the Cartagena Bay. Twenty-seven samples were collected from 3 sample stations during january, june and november of 2008. The retention times of the extracts of Shrimp were compared with standard mix of 20 organochlorine pesticides. Gas chromatography equipped with an microelectron capture detector was used as instrumental technique. The aim of this paper was determinate the residual contamination for organochlorine pesticides in shrimp muscle obtained in Cartagena's Beaches. The limit of detection of all organochlorine pesticides compounds was at the range of O.1-13 ngg^-1. The concentration of organochlorine pesticides residues in shrimp was lower than the maximum residue limit for aquatic animals as recommended by the FAO.
