Detection of chlorates and perchlorates in wines from the eastern Helan mountain region and dietary exposure assessment
To assess the unclear contamination status of chlorates and perchlorates in wines in eastern Helan mountain,Ningxia,a total of 331 wine samples were collected for pollution risk assessment. A method for simultaneous determination of chlorates and perchlorates using solid phase dispersive extraction-UPLC-MS/MS was established and optimized. Dietary exposure risk assessment was conducted using point estimation and hazard quotient (HQ) methods. The results showed that chlorate was detected in 51.1％ of samples and the content was ranged from 0 to 8.10 μg/kg,with an average of 1.16 μg/kg and median value of 0.132 μg/kg,perchlorate was found in 98％ of samples and content was from 0 to 0.53 mg/kg,with an average of 0.136 μg/kg and median of 0.103 μg/kg. Dietary exposure assessment revealed average daily intakes of 0～0.0068 μg/kg·d for chlorate and 0～0.39 μg/kg·d for perchlorate,with perchlorate levels exceed European Food Safety Authority (EFSA) established acceptable daily intake of 0.3 μg/kg·d. All samples had an HQ for chlorates less than 1,whereas 98.2％ of samples had an HQ for perchlorates below 1. The remaining 1.8％ of samples posed a potential health risk to humans regarding perchlorate consumption,while the health risk from chlorates was minimal.
