中文摘要:
      为全面了解我国东部近海海产品中有机氯农药(OCPs)和菊酯类农药(PYRs)的残留特征及健康风险,本研究以我国东部近海附近海域的典型海产品为研究对象,使用气相色谱-三重四极杆串联质谱仪(GC-MS/MS)对其体内两类农药的含量进行测定和相关分析。结果显示:东部近海海产品中,∑OCPs残留范围为2.2~1 864.7 ng·g-1( 均值为72.5 ng·g-1,以干质量计),∑PYRs浓度范围为 5.2~761.7 ng·g-1( 均值为 57.9 ng·g-1)。与软体动物类和甲壳类相比,∑OCPs 更容易蓄积在脂肪含量更高的鱼类中,而∑PYRs在3类生物中的残留量差异不显著;空间分布上,两类农药在海洋生物体内残留量的空间差异性均不显著(除烟台海域外);来源分析表明,OCPs污染主要源于历史残留,而PYRs可能与近海范围内陆域的城市卫生防护活动密切相关。研究表明,不同海产品中两类农药的总风险指数远小于1,健康风险处于安全水平。
英文摘要:
      To comprehensively understand the residual characteristics and food hazards of organochlorine(OCP)and pyrethroid(PYR) pesticides in marine products from the eastern China coastal seas, typical marine products from the target area were collected and analyzed using gas chromatography–tandem mass spectrometry. The ∑OCPs ranged from 2.2 ng·g-1 to 1 864.7 ng·g-1( calculated by dry matter), with a mean of 72.5 ng·g-1, and ∑PYRs ranged from 5.2 ng·g-1 to 761.7 ng·g-1, with a mean of 57.9 ng·g-1. ∑OCPs were more likely to accumulate in fish with higher fat content than in mollusks and crustaceans; however, the bodily residues of ∑PYRs showed no significant difference among the three types of organisms. In addition, the spatial differences of the two pesticides in marine organisms were not significant(except Yantai coastal water). OCPs mainly left over by history, while PYRs may be closely related to human activities in the land area near the offshore. The total risk index of two types of pesticides in seafood was much lower than 1, with no significant health risk.
