Occurrence of Chlorinated Paraffins in Bavarian House Dust Samples

House dust samples from Bavaria were examined for chlorinated paraffins using gas chromatography-mass spectrometry in ECNI mode. Middle-chain chlorinated paraffins (MCCPs) were detected in all studied samples. The concentrations of MCCPs varied between 4.12 µg/g and 237.54 µg/g. Short-chain chlorinated paraffins (SCCPs) were detected in 9 out of 11 studied samples. As compared to MCCPs, concentrations of SCCPs were on average 29 fold lower.
