A Baltic mystery
2014 (English)Other (Refereed)
HNPs are produced by macroalgae (seaweeds), phytoplankton, worms, sponges and other marine organisms. HNPs in the Baltic comprise halocarbons, bromophenols and their transformation products, and other compounds with diverse chemical structures. The HNPs derived from bromophenols are widespread in Baltic algae, fi sh and mussels, and include bromoanisoles, hydroxylated and methoxylated bromodiphenyl ethers (OH- and MeO-BDEs) and polybrominated dibenzo-p-dioxins (PBDDs). Some of these also have anthropogenic origins; bromophenols are used as industrial compounds, while MeO-BDEs and OH-BDEs are metabolites and photolysis products of polybrominated diphenyl ether fl ame retardants. Nonetheless, radiocarbon-14 dating has shown that most of the OH-BDEs and MeO-BDEs found in marine mammals and sponges are natural. The bromophenolderived HNPs have toxic properties which add to the ‘soup’ of anthropogenic toxic chemicals present in the Baltic.
