Abstract

The present study aimed to determine the mercury (Hg) levels and risk analysis of consumption of tambaqui Colossoma macropomum in fish farms in the Amazon region. In total 212 tambaqui muscle samples were collected from 10 fish farms in 5 states (Amazonas, Pará, Amapá, Roraima, and Rondônia). The Hg in tambaqui muscles in the Amazon region revealed that Amazonas and Amapá had the highest values. The monthly estimate of tambaqui consumption per month showed that children had the highest values compared to young people and adults. Meanwhile, in the states of Amazonas and Amapá, especially among children, the maximum monthly intake of tambaqui should be lower than in other localities. For the hazard quality, only tambaqui evaluated in fish farms in the states of Roraima, Rondônia and Pará presented safety levels. Therefore, routine biomonitoring of fish farms is crucial, especially tambaqui farms, as the main fish species farmed in Brazil.

来自亚马逊地区生产系统的亚马逊坦巴基鱼的汞评价和消费风险分析。

本研究旨在确定亚马孙地区养鱼场食用大斑鲷的汞（Hg）水平和风险分析。从5个州（亚马逊州、帕尔州、阿玛帕州、罗莱马州和Rondônia）的10个养鱼场共收集了212份坦巴基鱼肌肉样本。亚马逊地区tambaqui肌肉中汞含量以亚马逊和amapap地区最高。每月估计的坦巴吉消费量显示，与年轻人和成年人相比，儿童的消费量最高。同时，在亚马逊州和阿玛玛州，尤其是儿童，每月最大的坦巴基摄入量应该低于其他地区。在危险质量方面，只有在罗赖马州、Rondônia和paraima州的养鱼场评估的tambaqui达到了安全水平。因此，对养鱼场进行常规生物监测至关重要，尤其是作为巴西主要养殖鱼种的坦巴基养鱼场。

期刊介绍： Environmental Toxicology and Pharmacology publishes the results of studies concerning toxic and pharmacological effects of (human and veterinary) drugs and of environmental contaminants in animals and man. Areas of special interest are: molecular mechanisms of toxicity, biotransformation and toxicokinetics (including toxicokinetic modelling), molecular, biochemical and physiological mechanisms explaining differences in sensitivity between species and individuals, the characterisation of pathophysiological models and mechanisms involved in the development of effects and the identification of biological markers that can be used to study exposure and effects in man and animals. In addition to full length papers, short communications, full-length reviews and mini-reviews, Environmental Toxicology and Pharmacology will publish in depth assessments of special problem areas. The latter publications may exceed the length of a full length paper three to fourfold. A basic requirement is that the assessments are made under the auspices of international groups of leading experts in the fields concerned. The information examined may either consist of data that were already published, or of new data that were obtained within the framework of collaborative research programmes. Provision is also made for the acceptance of minireviews on (classes of) compounds, toxicities or mechanisms, debating recent advances in rapidly developing fields that fall within the scope of the journal.
