Abstract

Aquatic products are a significant source of arsenic exposure, with inorganic arsenic (iAs) posing a significant risk to humans. This study assessed iAs levels in 1191 aquatic products from Shenzhen, China (2018–2024), and estimated health risks. Shellfish had lower mean iAs levels (0.01 mg/kg ∼ 0.07 mg/kg), while crab, fish, and shrimp had higher levels (0.04 mg/kg ∼ 0.06 mg/kg). The iAs levels in shellfish were stable from 2018 to 2024. Health risk assessments showed estimated daily intake values ranging from 0.01 μg/kg·bw/day to 0.39 μg/kg·bw/day, with children having the highest exposure. The target hazard quotient exceeded 1 for fish and shrimp in high-consumption scenarios for children, indicating potential non-carcinogenic risks. Cancer risk estimates surpassed acceptable thresholds, especially for children and adolescents, suggesting an increased cancer risk with high consumption. Authorities should strengthen surveillance of iAs in aquatic products, especially shellfish and shrimp, and enhance environmental monitoring in Shenzhen.

水产品是砷暴露的重要来源，其中无机砷（iAs）对人类构成重大风险。本研究评估了中国深圳 1191 种水产品中的 iAs 含量（2018-2024 年），并估算了健康风险。贝类的iAs平均含量较低（0.01 mg/kg ∼ 0.07 mg/kg），而蟹、鱼和虾的iAs含量较高（0.04 mg/kg ∼ 0.06 mg/kg）。贝类中的 iAs 含量在 2018 年至 2024 年期间保持稳定。健康风险评估显示，估计日摄入量值从0.01微克/千克体重/天到0.39微克/千克体重/天不等，其中儿童的摄入量最高。在儿童高摄入量情况下，鱼和虾的目标危害商超过 1，表明存在潜在的非致癌风险。癌症风险估计值超过了可接受的阈值，尤其是儿童和青少年，这表明高摄入量会增加癌症风险。有关当局应加强对水产品，特别是贝类和虾类中 iAs 的监测，并加强深圳的环境监测。

期刊介绍： Food and Chemical Toxicology (FCT), an internationally renowned journal, that publishes original research articles and reviews on toxic effects, in animals and humans, of natural or synthetic chemicals occurring in the human environment with particular emphasis on food, drugs, and chemicals, including agricultural and industrial safety, and consumer product safety. Areas such as safety evaluation of novel foods and ingredients, biotechnologically-derived products, and nanomaterials are included in the scope of the journal. FCT also encourages submission of papers on inter-relationships between nutrition and toxicology and on in vitro techniques, particularly those fostering the 3 Rs. The principal aim of the journal is to publish high impact, scholarly work and to serve as a multidisciplinary forum for research in toxicology. Papers submitted will be judged on the basis of scientific originality and contribution to the field, quality and subject matter. Studies should address at least one of the following: -Adverse physiological/biochemical, or pathological changes induced by specific defined substances -New techniques for assessing potential toxicity, including molecular biology -Mechanisms underlying toxic phenomena -Toxicological examinations of specific chemicals or consumer products, both those showing adverse effects and those demonstrating safety, that meet current standards of scientific acceptability. Authors must clearly and briefly identify what novel toxic effect (s) or toxic mechanism (s) of the chemical are being reported and what their significance is in the abstract. Furthermore, sufficient doses should be included in order to provide information on NOAEL/LOAEL values.
