Dietary intake is the major route for the exposure of residents to short-chain chlorinated paraffins (SCCPs). SCCPs are classified as persistent organic pollutants (POPs) by the Stockholm Convention since May 2017. This study assessed the general population's dietary exposure to SCCPs through supermarket products. Five food categories, which included 40 food species, were collected from five supermarkets in April 2019. The SCCP concentrations in all food matrices varied between 58.6 and 1977 ng g−1 dry weight (dw), with the average and standard deviation (SD) value of 301 ± 379 ng g−1 dw. Generally, the SCCP concentrations in animal-origin food matrices were higher than those in plant-origin food matrices. The C10Cl7 congeners were predominant among the congener groups of SCCPs. The proportion of C10 congeners in the animal-origin food samples (29.8%) was lower than that in the plant-origin food samples (39.7%), and the C13 congeners showed a contrasting result. The estimated daily intake (EDI) of SCCPs through dietary intake for the residents was 3109 ng kg−1 day−1, which is much lower than the standards of European Food Safety Authority (10 mg kg−1 day−1) for SCCPs. Risk assessment based on the supermarket foods indicated that SCCP exposure through dietary intake does not cause adverse effects to human health according to the margin of exposure (MOE).
