湖北地区市售白酒中邻苯二甲酸酯类物质的监测结果及分析

Monitoring results and analysis of phthalates contamination in marketed liquors of Hubei province

目的对湖北地区市售白酒中邻苯二甲酸脂类物质的污染水平进行分析。方法按照《国家食品污染和有害因素风险工作手册》对湖北地区9个地市销售的89份白酒样品中的邻苯二甲酸二丁酯(dibutyl phthalate,DBP)、邻苯二甲酸二(2-乙基)己酯(di 2-ethyl hexyl phthalate,DEHP)、邻苯二甲酸二异壬酯(diisononyl phthalate,DINP)等17种邻苯二甲酸酯类化合物进行监控和风险评估。结果检测的89份白酒样品中,DBP超标率为29.2%;最高浓度高达23.48 mg/kg,超出国家标准限量值(0.3 mg/kg)78倍,DEHP的浓度均未超过国家标准限量值(1.5 mg/kg),DINP均未检出,其余14种邻苯二甲酸酯类物质部分有检出。结论湖北省市售白酒中存在一定程度的邻苯二甲酸酯类物质污染,需引起重视并进行连续监测。

Objective To investigate the phthalates contamination in liquors collected from Hubei province.Methods According to the Standard Operation Procedure of National Food Contamination and Harmful Factors Risk Workbook, 17 types of phthalates, including dibutyl phthalate（DBP）, di 2-ethyl hexyl phthalate（DEHP） and diisononyl phthalate（DINP）, etc. were determined in 89 liquor samples collected from 9 cities in Hubei province.Results In the 89 liquor samples, the exceeding rates of maximum residue limits（MRLs） was 29.2%, with the highest concentration of 23.48 mg/kg which was 78 times over the regulation（0.3 mg/kg）. The concentration of DEHP was below the MRLs（1.5 mg/kg）. DINP was not detected in all samples. The other 14 types of phthalates were detected in part of samples. Conclusion Phthalates contamination was found in liquors collected from Hubei province to some extent, so the monitoring and supervision should be strengthened.
