摘要

The AOX, EOX, dioxins and furans content obtained during five years monitoring program of Nueva Aldea Cellulose Industrial Complex, carried out to verify the operation of a submarine discharge in the coastal platform off Itata river mouth is presented. Sampling results every three months since May 2006 through November 2010, shows a seawater AOX average concentration between 0.015and 0.220 and ND (not detected) to 0.180 mg L-1 for subtidal and intertidal environments, respectively. The average seawater dioxins and furans content varies between ND to 0.0099 ng TEQ L-1 and ND to 0.0030 ng TEQ L-1, for subtidal and intertidal environments, respectively, dominated mainly by OCDD, OCDF, HpCDD y HpCDF congeners. The average sediment AOX content varies between 55.5 to 247.5 and 47.5 to 250.5 mg kg-1 for subtidal and intertidal environments, respectively. The evaluated organisms presented an average AOX content between ND to 116.0; 0.00 to 186.8;0.73 to 127.9 and ND to 424.4 mg kg-1 and an EOX average content between ND to 7.3; 0.00 to 10.2; ND to 19.6 and ND to 2.2 mg kg-1 for gastropods, crustaceans, fishes and bivalves mollusks, respectively. The average dioxins and furans concentration for gastropods, crustaceans, fishes varies between ND to 0.0001; ND to 0.0044 and ND to 0.0062 ng TEQ g-1, respectively, dominated mainly by OCDD, OCDF, HpCDD y HpCDF congeners. It is concluded that the analyzed COP's does not present any seasonal or spatial pattern allowing identification of any localized sources, instead, theses result strongly suggest that the presented values correspond to local background levels.
