概括

巴西亚马逊地区的鱼类积累了 (Cr) 和 (Hg) 的含量,超过了人类消费的安全限值,并带来毒理风险. 应控制野生捕捞鱼的消费,并建议持续监测.

科学领域:

环境科学环境科学
毒理学毒理学毒理学
公共卫生公共卫生

背景情况:

鱼是亚马逊人群的主要蛋白质来源.
人类对亚马逊鱼类微量元素积累和相关的人类健康风险的影响还未得到充分研究.
了解鱼类中的金属污染对于区域食品安全至关重要.

研究的目的:

为了评估亚马逊鱼类中的微量元素和金属含量.
研究鱼类起源,食习惯和金属积累之间的关系.
评估鱼类消费对亚马逊人口的毒理和致癌风险.

主要方法:

在56个来自11个物种的鱼样中分析了10种微量元素和金属 (Cr, Mn, Fe, Ni, Cu, Zn, As, Cd, Pb, Hg).
取样地点,食习惯和元素度之间的相关性分析.
基于估计的每日摄入量和参考剂量对人类健康的风险评估.

主要成果:

采样地点和元素含量之间没有显著的相关性.
基于鱼的食物位置,金属积累的显著差异.
(Cr) 和 (Hg) 度超过了巴西鱼类消费安全限值.
估计每天摄入的Hg, (As) 和Cr超过了口服参考剂量,这表明有毒性问题.

Types of Toxins

Types of Toxins

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

Minerals

Minerals

Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.
