Resumen:
Temporal and spatial distribution of organochlorine pesticides (OCPs) and the organophosphate pesticide chlorpyrifos,one of the main insecticides used in Argentina, was evaluated in two populations of the sea anemoneBunodosoma zamponii living under different anthropological stressors: Las Delicias (LD) adjacent to awastewaterplant, and Punta Cantera (PC) a reference site. Pesticides were analyzed throughout the year inwater, sedimentsand whole organisms. Chlorpyrifos represented 50% of the total pesticide found inwater samples during winter.HCHs and drinswere predominant in sediment samples, mainly in LD. Total pesticide concentration in anemonesfrom LD was higher than those from PC during winter (mainly associated with HCHs, endosulfans, DDTs andchlorpyrifos levels), coincidentwith the main period of effluent discharge to the coast after pesticide applicationsand also the rainiest season. Dissimilarities among anemones populations could stemfroma differential input ofpesticides in each site and/or a contrasting physiological status of the populations.
