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.
