Abstract
WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Short-chain chlorinated paraffins (SCCPs) are persistent organic pollutants that are toxic to organisms. Medium-chain chlorinated paraffins (MCCPs) have similar properties. Chlorinated paraffins (CPs) may be biomagnified through the food chain, thereby threatening human health. WHAT IS ADDED BY THIS REPORT? The concentrations of SCCP and MCCP in each food sample were 5-265 and 4-306 ng/g, respectively. The estimated dietary exposure to CPs was relatively lower than the threshold set in the current guidelines. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? The production and use of SCCP and MCCP have not been prohibited in China yet. Further studies are needed to assess the health risks through dietary exposure to CPs.
