| Abstract: | This study deals with the levels of aromatic and aliphatic hydrocarbon quantification in sediments and organisms in Cartagena Bay (Colombia), 1996-1997. Sediments (14 stations) and bivalves (2 stations) were monitored at different times of the year. Areas with high values were in the north with concentrations above 100 microg/g with a maximum of 1415 microg/g. Areas with low values were located toward the south, near the outlet of the Canal del Dique and Barú Island, with values below 10 microg/g. In other areas concentrations were between 50 and 100 microg/g. A decrease in sediment concentrations of hydrocarbons has occurred since 1983, but levels in some sectors are still similar to those in polluted areas. Organisms have relatively low values (8-30 microg/g for bivalves, and 10-40 microg/g for fish). |
