Short- and medium-chain chlorinated paraffins in biota from the European Arctic — differences in homologue group patterns

Short- and Medium-Chain Chlorinated Paraffins in Air and Soil of Subtropical Terrestrial Environment in the Pearl River Delta, South China: Distribution, Composition, Atmospheric Deposition Fluxes, and Environmental Fate

“…Congeners with more carbon and/or chlorine atoms (C 12−13 Cl 8−10 ) also exhibited higher concentrations in Dongguan (e.g., S19 and S20), compared to the rural areas in Huizhou (e.g., S58) for the relative lower volatility and less transport ability. 39 The SCCP homologue patterns in soils were different from those in the commercial CP mixtures; 23,35,40 however, there were also substantial spatial differences observed. Figure 3b showed that C 10 had accounted for 10− 40% and a similar variation was seen for C 13 .…”

Organohalogen pollutants in surface particulates from workshop floors of four major e-waste recycling sites in China and implications for emission lists

“…The most abundant SCCP in the particulate samples was the C 13 homologue (average contribution up to 45.4%), followed by the C 12 homologue (average contribution up to 33.6%) and C 11 homologue (average contribution up to 22.3%) (Fig. 2), unlike the commercial SCCP mixtures used in developed countries (dominant by C 11 homologues, 38-45%) (Reth et al, 2006) and China (dominant by C 10 homologues, 59-72%) (Gao et al, 2012). The vapor pressure and subcooled-liquid water solubility tend to decrease with increasing carbon chain length (Glüge et al, 2013).…”

Occurrence, bioaccumulation and long-range transport of short-chain chlorinated paraffins on the Fildes Peninsula at King George Island, Antarctica

“…The detection of SCCPs in the polar regions would provide direct evidence for their long-range transport, but SCCPs have been observed in polar regions in only a few studies. The concentrations of SCCPs were studied in the biota and sediment samples from Arctic and sub-Arctic environments (Reth et al, 2006;Strid et al, 2013;Tomy et al, 2000;Tomy et al, 1999). For Antarctica, the only data for SCCPs are from the air samples collected on the Fildes Peninsula (Ma et al, 2014c).…”
