摘要
目的分析温州市市售海捕虾二氧化硫残留,评估居民食用海捕虾暴露二氧化硫的健康风险。方法于2015—2016年在温州市采集246份市售海捕虾并检测二氧化硫残留含量,结合2008年浙江省居民膳食调查中温州市居民消费量调查数据,采用点评估的方法评估温州市居民食用海捕虾暴露二氧化硫的风险。结果海捕虾全虾、虾肉中二氧化硫中位数分别为20.05和10.65 mg/kg,虾肉低于全虾(P<0.05);全虾、虾肉中二氧化硫超标率分别为19.11%和5.69%,虾肉低于全虾(P<0.05)。普通人群食用全虾、虾肉二氧化硫暴露量的点估计值分别为0.045 9和0.007 6 mg/kg体重;高消费人群(海捕虾消费量≥P97.5)食用全虾和虾肉二氧化硫暴露量的点估计值分别为0.114 2和0.018 9 mg/kg体重;女性食用海捕虾二氧化硫暴露量高于男性,但均低于食品添加剂专家委员会(JECFA)规定的二氧化硫每日允许摄入量上限(0.7 mg/kg体重)。结论居民食用温州市市售海捕虾暴露二氧化硫的健康风险较低。
Objective To assess the level of sulfur dioxide（SO_2） residues in sea shrimps on the market and to evaluate the health risk of the SO_2 exposure of Wenzhou population by eating sea shrimp.Method SO_2 residues in 246 sea shrimp samples collected from Wenzhou market from 2015 to 2016 were analyzed.The point assessment method was used to evaluate the risk of SO_2 exposure for consumers,using the data of residents＇ consumption survey in 2008 in Zhejiang Province.Results The median of SO_2 residual in the whole shrimp and the shrimp without shell were 20.05 mg/kg and10.65 mg/kg respectively（P0.05）.The over-standard rate of SO_2 for the whole shrimp and the shrimp without shell were 19.11% and 5.69%（P0.05） respectively.The average exposure of SO_2 in general population by eating the whole shrimp and the shrimp without shell were 0.045 9 mg/kg BW and 0.007 6 mg/kg BW respectively.However,the exposure of SO_2 in high-consuming population（P97.5） by eating the whole shrimp and the shrimp without shell were0.114 2 mg/kg BW and 0.018 9 mg/kg BW respectively.The exposure level of SO_2 in men were lower than in women.Conclusion The health risk of the SO_2 exposure by eating sea shrimp in general population and high-consuming population is in a low level in Wenzhou.
