中文摘要:

      目的 了解江西省市售油茶籽油中3-氯丙醇酯（3- chloropropanol ester，3-MCPDE）、缩水甘油酯（glycidyl ester，GE）、邻苯二甲酸二正丁酯（dibutyl phthalate，DBP）及邻苯二甲酸二(2-乙基)己酯（bis(2-ethylhexyl) phthalate，DEHP）新型风险因子污染情况，并对其进行风险评估。方法 采用气相色谱-质谱联用仪测定29批次油茶籽油中3-MCPDE、GE、DBP及DEHP含量，并采用膳食暴露评估方法对其暴露风险进行分析。结果 油茶籽油中3-MCPDE含量范围为0.11~4.52 mg/kg，检出率为75.9%，问题率为10.3%；GE含量范围为0.13~11.76 mg/kg，检出率为72.4%，问题率为44.8%；DBP含量范围为0.43~12.9 mg/kg，问题率为34.5%；DEHP含量范围为0.57~9.69 mg/kg，检出率为55.2%，问题率为20.7%。居民通过食用油茶籽油摄入DBP、DEHP、3-MCPDE和GE的平均暴露量范围为0.56~0.75 μg/(kg ?BW)，DBP、DEHP及3-MCPDE暴露风险范围为1.12~37.37%，GE暴露风险MOE值男性为3948.94，女性为3347.52，MOE值均小于10000。结论 油茶籽油存在一定程度的3-MCPDE、GE、DBP及DEHP污染风险，居民通过油茶籽油摄入DBP、DEHP及3-MCPDE对人体造成危害的可能性很小，但对于GE暴露的健康风险需要更多的关注。

      Objective To understand the pollution situation of new risk factors such as 3- chloropropanol ester (3-MCPDE), glycidyl ester (GE), dibutyl phthalate (DBP）and bis(2-ethylhexyl) phthalate (DEHP) in camellia oleifera seed oil of Jiangxi province, and make risk assessment. Methods The contents of 3-MCPDE, GE, DBP and DEHP in 29 batches of camellia oleifera seed oil were determined by gas chromatography-mass spectrometry, and the exposure risk was analyzed by dietary exposure assessment method. Results The content of 3-MCPDE in camellia oleifera seed oil ranged from 0.11 to 4.52 mg/kg, the detection rate was 75.9%, and the problem rate was 10.3%. GE content ranged from 0.13 to 11.76 mg/kg, the detection rate was 72.4%, and the problem rate was 44.8%. The content of DBP ranged from 0.43 to 12.9 mg/kg, and the problem rate was 34.5%. The range of DEHP content is 0.57~9.69 mg/kg, the detection rate is 55.2%, and the problem rate is 20.7%. The average exposure of residents to DBP, DEHP, 3-MCPDE and GE through edible oil tea seed oil ranged from 0.56 to 0.75 μg/(kg ?BW), and the exposure risk of DBP, DEHP and 3-MCPDE ranged from 1.12 to 37.37%. The exposure risk of GE was 3,948.94 for men and 3,347.52 for women, and the MOE values were all less than that of others.
