英文摘要: Halogenated natural products in biota of the Baltic Sea include bromoanisoles (BAs) and methoxylated bromodiphenyl ethers (MeO-BDEs). We identified biogenic 6-MeO-BDE47 and 2′-MeO-BDE68 in Baltic water and air for the first time using gas chromatography – high resolution mass spectrometry. Partial pressures in air were related to temperature by: log p/Pa = m / T(K) + b. We determined Henry's law constants (HLCs) of 2,4-dibromoanisole (2,4-DiBA) and 2,4,6-tribromoanisole (2,4,6-TriBA) from 5 to 30 °C and revised our assessment of gas exchange in the northern Baltic. The new water/air fugacity ratios (FRs) were lower, but still indicated net volatilization in May–June for 2,4-DiBA and May – September for 2,4,6-TriBA. The net flux (negative) of BAs from Bothnian Bay (38,000 km2) between May – September was revised from –1319 to − 532 kg. FRs of MeO-BDEs were > 1, suggesting volatilization, although this is tentative due to uncertainties in their HLCs and binding to dissolved organic carbon. © 2016 Citation statistics:
