چکیده انگلیسی
Polydimethylsiloxane (PDMS) based passive water samplers deployed at Normanby Island, Great Barrier Reef (Australia) from 2007 to 2013 were analyzed for halogenated natural products (HNPs). Altogether, 38 samples, typically deployed for 30â¯days, were studied. Five HNPs (Q1, 2â²âMeO-BDE 68, BC-10, 2,4âdibromoanisole and 2,4,6âtribromoanisole) were detected in all samples. Most samples (>90%) featured 2,2â²âdiMeO-BB 80, 6âMeO-BDE 47, 2â²,6âdiMeO-BDE 68 and 2,4âdibromophenol. In addition, tetrabromoâNâmethylpyrrole (TBMP) was detected in ~80% and Cl6-DBP in ~30% of the samples. Estimated time weighted maximum water concentrations were >150â¯pg Q1 and 60â¯pg 2â²âMeO-BDE 68 per L seawater. Typically, the concentrations were varying from year to year. Moreover, time weighted average water concentration estimates did not reveal consistent maximum trend levels within a given year. Additional screening analysis via GC/MS indicated the presence of several polyhalogenated 1â²âmethylâ1,2â²âbipyrroles (PMBPs), 1,1â²âdimethylâ2,2â²âbipyrroles (PDBPs), and 1âmethylpyrroles (PMPs) along with four brominated Nâmethylindoles and several other polyhalogenated compounds at Normanby Island.
