| 摘 要： | 为探讨南黄海苏北浅滩浒苔在农药方面的食用风险,本文以位于南黄海苏北浅滩的如东、大丰和吕四等地所采集的浒苔为研究对象,采用气相色谱质谱法(GC-MS,Agilent 7890A/5975C)分析8种有机氯(OCPs)、4种菊酯(PEs)和9种有机磷农药(OPPs)的残留浓度及食用风险评价。结果表明:浒苔体内OCPs、PEs和OPPs的浓度范围分别为15.86~56.93 ng·g~(-1)、42.03~133.49ng·g~(-1)和9.42~13.36 ng·g~(-1);浒苔对PEs的富集能力最强,其次是OCPs,富集能力最弱的是OPPs;浒苔体内的8种OCPs、4种PEs和9种OPPs农药的食用风险评估中单一风险(ave THQ)值和总风险指数(HI)值均远小于1;从长期和短期摄入量可得出,浒苔体内农药的风险商值均小于1。研究表明,南黄海苏北浅滩的浒苔由三类农药造成的风险在可控范围内,本文研究结果为日后南黄海苏北浅滩浒苔的大规模食用提供了科学依据。

| Abstract: | Turning Enteromorpha into a commercial seaweed product can not only solve the related algal bloom problem but also supply consumers with essential nutrients. In order to evaluate the health risks to the consumers posed by pollutants such as pesticides that might be enriched in Enteromorpha, in this study, the levels of organochlorine pesticides(OCPs), pyrethroids(PEs), and organophosphorus pesticides(OPPs) in Enteromorpha were analyzed using a GC-MS Agilent 7890A/5975C and the health risks from these pollutants were estimated. The concentrations were in the ranges of 15.86~56.93 ng·g-1, 42.03~133.49 ng·g-1, and 9.42~13.36 ng·g-1 for OCPs, PEs, and OPPs, respectively. Followed by OCPs and OPPs, PEs showed the greatest bioaccumulation in Enteromorpha. The individual and total health risk(HI) index values of eight OCPs, four PEs, and nine OPPs were all calculated to be far below 1, and the risk entropy values were all calculated as less than 1 with short-term and long-term consumption, indicating no significant dietary risk would be present if people consume Enteromorpha from the Subei Shoal as food. This study provides a scientific basis for the large-scale utilization of Enteromorpha in the Southern Yellow Sea. |
