Abstract
- Chlorinated paraffins (CPs) are produced in large amounts and used worldwide. Dietary intake is the primary pathway for the exposure of pets to CPs, but limited information is available concerning the potential contamination of pet food by CPs. In the present study, the concentrations and congener group profiles of short-chain CPs (SCCPs) and medium-chain CPs (MCCPs) were assessed in 35 imported commercial dry cat and dog foods collected in China, and the estimated daily intakes of SCCPs and MCCPs for cats and dogs through the consumption of such foods was calculated. The concentrations of SCCPs and MCCPs in the cat and dog foods were determined to be in the ranges of 108–45,300 ng/g (median: 1340 ng/g) and 3.8–52,700 ng/g (median: 11 ng/g), respectively. The predominant congener groups were C10Cl6 for SCCPs and C14Cl7-8 for MCCPs. The high levels of CPs found in certain pet foods suggest the potential for adverse health effects.
