POLYBROMINATED DIOXINS AND DIBENZOFURANS: A GLOBAL CONCERN?
The PBDD/Fs were analyzed in mollusc and crustacean samples from the Baltic Sea, NE Atlantic, NW Atlantic, Mediterranean Sea, S Atlantic, N Pacific, S Pacific and Indian Ocean and were found in all samples. Thus, they are ubiquitous in the marine environments. There was an enormous spread in concentrations, which spread four orders of magnitudes between all of the samples and three orders of magnitude between samples from the same water (North East Atlantic). The highest levels were detected in the Baltic Sea (about 20,000 pg/g dry weight). Similar concentrations were found in opposite corners of the world, i.e. North East Atlantic and South Pacific. For the remaining bodies of water the number of samples was to low to allow any meaningful comparisons of concentrations, but these all fall within the range of the North East Atlantic and South Pacific samples. The ubiquity of the pollutants, high peak concentrations, and high variability indicate that the PBDD/Fs have to be considered in environmental and human risk assessments.
