High production rates of chlorinated paraffins (CPs) and their widespread use resulted in a global contamination. Since 2017, short-chain CPs (SCCPs, C-C) are listed as persistent organic pollutants (POPs) in the Stockholm Convention. Technical CP mixtures contain hundreds of homologues and side products such as chlorinated olefins (COs), diolefins (CdiOs) and triolefins (CtriOs).

- The study investigates human exposure to chlorinated paraffins (CPs) in sewage sludge from a Swiss wastewater treatment plant (WWTP) over several years, focusing on the regulation of short-chain CPs (SCCPs) since 2017 as persistent organic pollutants.
- Using advanced liquid chromatography mass spectrometry, researchers detected thousands of ions related to CPs and chlorinated olefins (COs), identifying a range of homologues and their distributions in the sludge.
- Results show a significant decrease in the levels of SCCPs (84%) and other chlorinated compounds from 1993 to 2020, indicating shifts in the presence of banned substances and suggesting that higher-chlorinated SCCPs have been replaced by
