“…Semiquantitative concentrations of BCPs and BCOs in dust samples (median concentrations of 5.4 and 0.18 μg/g, respectively) are comparable to CPs, and 1–2 orders of magnitude higher than those in the atmosphere and sediments at some sites . More than 70 kinds of sulfur-containing chlorinated paraffins (S-CPs) and 399 oxygen-containing CPs (CPO x s, including 285 congeners of chlorinated fatty acid methyl esters, CFAMEs) were detected in serum samples of Chinese general population and the levels of ∑CPO x s were 202.2 ± 324.7 ng/mL with a detection frequency of 100%, which were comparable to the concentration of ∑MCCPs (142.8 ± 144.6 ng/mL). , …”
