概括

这项研究分析了来自印度的金枪鱼种中的14种金属,发现高摄入量超过安全限值,但其他金属对健康没有重大风险. 建议进行持续的海鲜监测.

科学领域:

环境科学环境科学
食品安全食品安全
海洋生物学海洋生物学

背景情况:

海洋鱼类中的微量和重金属积累对人类健康构成潜在风险.
鱼种类是蛋白质的重要来源,但可以从环境中生物积累金属.
了解商业重要鱼类中的金属度对于公共卫生评估至关重要.

研究的目的:

在两个金枪鱼物种中量化14种微量和重金属的度: Thunnus albacares和Katsuwonus pelamis.
根据金属积累,评估与这些金枪鱼种类的消费相关的潜在人类健康风险.
为了评估金属分布在不同的组织 (肌肉,肝脏,,皮肤) 的研究金枪鱼.

主要方法:

诱导合等离子体质谱法 (ICP-MS) 用于精确的金属量化.
分析包括Thunnus albacares和Katsuwonus pelamis的肌肉,肝脏,和皮肤组织.
估计每日摄入量 (EDI) 和目标危险系数 (THQ) 被计算出以评估健康风险.

主要成果:

在这两种金枪鱼中, (Se) 呈现出最高的估计日摄入量 (EDI),超过了暂时可容忍每周摄入量 (PTWI).
金属度模式因器官而异,Se,Al,Fe和Zn经常在更高水平上被检测到.
对有毒金属的目标危险系数 (THQ) 值在儿童和成人均低于1,这表明没有重大健康问题.

结论:

虽然这些金枪鱼种的摄入量超过了推限值,但其他有毒金属并没有对健康造成重大风险.
这些发现表明,从Tharuvaikulam海岸的金枪鱼的消费在毒性金属暴露方面通常是安全的.
建议继续监测来自该地区的海鲜中的微量金属含量,以确保持续的消费者安全.

The Periodic Table and Organismal Elements

The Periodic Table and Organismal Elements

Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally occurring, and only a few of them are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.

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.
Environmental pollutants like...
