| 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. |
