To evaluate the health risks associated with the consumption of crayfish, nine types of heavy metals in both crayfish and abdominal muscles of crayfish were investigated. Crayfish samples were collected from rice-crayfish-based coculture breeding modes from different areas located in the middle and lower reaches of the Yangtze River. The average concentrations of heavy metals in the whole crayfish were much higher than the abdominal muscle of crayfish. The estimated daily intake (EDI) of heavy metals in the abdomen of crayfish was calculated to assess the noncarcinogenic risk and the overall noncarcinogenic risk including the target hazard quotient (THQ), the hazard index (HI) and carcinogenic risk (CR). The results of the present study showed that the consumption of crayfish may not present an obvious health risk to human associated with heavy metals. However, the THQ values of As in the abdominal muscles of crayfish for adults in EnShi (ES) and children in JiaYu (JY) should be of concern due to the higher contribution to the potential health risks of crayfish compared to other metals. Through X-ray photoelectron spectroscopy (XPS) detection of heavy metal As, it is found that As in crayfish culture environment mainly exists in the form of As3+.Therefore, the quality and quantity of crayfish consumption should be moderated to prevent the bioaccumulation of As. The results indicate that crayfish cultured in different areas may have similar pollution levels and\/or emissions from the same pollution sources.<\/jats:p>","DOI":"10.3390\/foods11030261","type":"journal-article","created":{"date-parts":[[2022,1,19]],"date-time":"2022-01-19T08:20:57Z","timestamp":1642580457000},"page":"261","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Investigation of Bioaccumulation and Human Health Risk Assessment of Heavy Metals in Crayfish (Procambarus clarkii) Farming with a Rice-Crayfish-Based Coculture Breeding Modes"],"prefix":"10.3390","volume":"11","author":[{"given":"Fangjun","family":"Peng","sequence":"first","affiliation":[{"name":"College of Food Science and Technology, Huazhong Agricultural University, Wuhan 430070, China"},{"name":"National R & D Branch Center for Conventional Freshwater Fish Processing, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiawen","family":"Li","sequence":"additional","affiliation":[{"name":"QianJiang Public Inspection and Testing Center, Qianjiang 433100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5788-5581","authenticated-orcid":false,"given":"Zhiyong","family":"Gong","sequence":"additional","affiliation":[{"name":"Key Laboratory for Deep Processing of Major Grain and Oil of Ministry of Education, Wuhan Polytechnic University, Wuhan 430023, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bing","family":"Yue","sequence":"additional","affiliation":[{"name":"Department of Scientific Education & International Cooperation, China National Center for Food Safety Risk Assessment, Beijing 100022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueli","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mathematics and Statistics, Beijing Technology and Business University, Beijing 100048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8257-0722","authenticated-orcid":false,"given":"Anne","family":"Manyande","sequence":"additional","affiliation":[{"name":"School of Human and Social Sciences, University of West London, Middlesex TW8 9GA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongying","family":"Du","sequence":"additional","affiliation":[{"name":"College of Food Science and Technology, Huazhong Agricultural University, Wuhan 430070, China"},{"name":"National R & D Branch Center for Conventional Freshwater Fish Processing, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2575","DOI":"10.1016\/j.envpol.2011.06.011","article-title":"Ecological risk assessment of heavy metals in sediment and human health risk assessment of heavy metals in fishes in the middle and lower reaches of the yangtze river basin","volume":"159","author":"Yi","year":"2011","journal-title":"Environ.
