Pollution status and health risk assessment of cadmium and inorganic arsenic in shrimps
Objective To monitor the contents of heavy metals cadmium and inorganic arsenic in dried shrimps sold in Hainan Province and carry out health risk assessment.Methods From May to July 2021,a total of 60 shrimp samples were collected from farmers'markets in six cities and counties of Hainan Province(Danzhou City,Lingao County,Ledong County,Wenchang City,Sanya City,Qionghai City).The samples were analyzed by inductively coupled plasma mass spectrometry,liquid chromatography atomic fluorescence spectrometry,and evaluated by national limit standard method,single factor pollution index method,Nemero pollution index method,and health risk index.Results The detection rate of cadmium and arsenic in 60 samples of dried shrimps was 100％,of which the over standard rate of cadmium was 93.3％,and no inorganic arsenic was detected.Conclusions Through the sampling inspection of shrimps from farmers'markets in six cities and counties in Hainan Province,it is found that cadmium pollution content in shrimps is high,which is harmful to human health,and should be paid great attention to.It is suggested that relevant departments should update the limit standards of relevant polluting elements in time to ensure the safety of seafood food.
