Time Trends of Polybrominated Diphenyl Ethers (PBDEs) in Antarctic Biota.

For example, time trends of PBDEs in samples collected from Swedish mothers indicate a decreasing trend for most PBDEs, except for BDEs 153 and 209, from 1996 to 2010. 17 PBDEs also decreased in Baltic herring over the last decade. 18 Across the Great Lakes in North America, PBDEs in fish started to decline in 1999–2000. 19 So far, no consistent set of Antarctic samples has been available to document

Phytoplankton Trends Few significant correlations were detected between PBDE phytoplankton concentrations and δ 15 N values except for the 2010/2011 season, where almost all congeners detected showed a negative trend of decreasing concentration with increasing δ 15 N value.
