Abstract

Arsenic (As) is naturally occurring and is found in different forms, some of which are considered toxic to human health and frequently present in fishery resources. The aim of this work was to determine the contribution of toxic As species to the total As in muscle of two commercial fish species (Micropogonias furnieri and Urophycis brasiliensis) and to assess the toxicological risk associated with their consumption, considering different exposed groups. The total As concentrations found exceeded local guideline recommendations (> 1 mg kg⁻¹ wet weight), but the concentrations of the toxic As species were below this threshold. The inorganic As levels do not exceed the international guideline recommendations (0.03–0.15 μg kg⁻¹ bw per day of iAs). Both interspecific and intraspecific differences in As concentrations were found. Non-carcinogenic and carcinogenic risk values indicated that the exposed groups would not experience health risks through consumption of either fish species. However, due to the lack of an established safe consumption limit for iAs or As species worldwide, there are currently no legal tools to ensure that these fish species are safe for human consumption.

西南大西洋沿海海域食用两种鱼类对健康风险的砷形态评价

砷是自然存在的，以不同的形式存在，其中一些被认为对人类健康有毒，经常存在于渔业资源中。这项工作的目的是确定两种商业鱼类（furnieri Micropogonias和Urophycis brasiliensis）肌肉中有毒As物种对总As的贡献，并在考虑不同暴露群体的情况下评估与它们的消费相关的毒理学风险。发现的总砷浓度超过了当地的指导建议（湿重1mg kg-1），但有毒砷种类的浓度低于这一阈值。无机砷含量未超过国际指导建议（每天0.03-0.15 μg kg-1 bw）。种间和种内砷浓度均存在差异。非致癌性和致癌性风险值表明，接触人群不会因食用任何一种鱼类而面临健康风险。然而，由于在世界范围内对iAs或iAs鱼种缺乏既定的安全消费限制，目前没有法律工具来确保这些鱼种可供人类安全食用。

期刊介绍： Archives of Environmental Contamination and Toxicology provides a place for the publication of timely, detailed, and definitive scientific studies pertaining to the source, transport, fate and / or effects of contaminants in the environment. The journal will consider submissions dealing with new analytical and toxicological techniques that advance our understanding of the source, transport, fate and / or effects of contaminants in the environment. AECT will now consider mini-reviews (where length including references is less than 5,000 words), which highlight case studies, a geographic topic of interest, or a timely subject of debate. AECT will also consider Special Issues on subjects of broad interest. The journal strongly encourages authors to ensure that their submission places a strong emphasis on ecosystem processes; submissions limited to technical aspects of such areas as toxicity testing for single chemicals, wastewater effluent characterization, human occupation exposure, or agricultural phytotoxicity are unlikely to be considered.
