Objective To investigate the pollution states of lead， cadmium， methyl mercury， inorganic arsenic and chromium for sold aquatic products in Zhuhai City， and to assess their exposure risk.Methods The total of 666 sold aquatic products samples in Zhuhai City were collected during 2018—2022. The level of lead， cadmium， methyl mercury， inorganic arsenic and chromium in samples were analyzed by inductively coupled plasma-mass spectrometry （ICP-MS） and liquid chromatograph inductively coupled plasma-mass spectrometry （LC-ICP-MS）， evaluated by the method of single-factor pollution index and Nemerow integrated pollution index， based on the dietary intake of residents in Zhuhai to assess its potential health hazard.Results Shellfish had the highest levels of lead， cadmium， inorganic arsenic， chromium and fish had the highest levels of methylmercury. The P_n of the four aquatic products was at safe levels， but the P_cadmium of shellfish and cephalopods was mildly contaminated. The average dietary exposures and high-end dietary exposures of lead， cadmium， methylmercury， inorganic arsenic， and chromium to health of resident were acceptable.Conclusion There has been the varying degrees of cadmium pollution of sold aquatic products in Zhuhai City， especially shellfish and cephalopod. It is necessary to strengthen the monitoring of dietary exposure risk of high-consumption groups in cadmium and methyl mercury， and to further carry out cumulative exposure risk assessment.
