概括

在国内种植的作物可以积累和多基基物质 (PFAS). 一年作物,特别是蔬菜, PFAS 含量较高,表明消费可能带来健康风险,即使远离工业来源.

科学领域:

环境化学环境化学
食品安全食品安全
毒理学毒理学毒理学

背景情况:

国内种植的作物是人体暴露在per-和多醇基物质 (PFAS) 的潜在来源.
有限的实地研究存在于各种作物中的PFAS积累以及土壤特征对生物可用性的影响.
评估PFAS风险是复杂的,因为各种化学品及其不同的特性.

研究的目的:

调查PFAS在各种本土作物和土壤中的积累情况.
检查土壤特性和接近化工厂对作物PFAS水平的影响.
为了评估人类暴露的风险和潜在的健康影响,消费污染的本土产品.

主要方法:

分析了29个遗留,前体和新出现的PFAS在88个花园的土壤形状,雨水和食用部分.
在不同距离化工厂的花园中比较PFAS度.
评估土壤和作物之间的关系,并使用土壤特征进行预测建模.
人类摄入量的估计和与可容忍的每周摄入量水平的比较.

主要成果:

在离化工厂更近的地方发现土壤PFAS度更高.
一年作物,特别是蔬菜,积累的PFAS含量高于多年作物.
土壤-作物 PFAS 关系较弱,表明其他因素影响生物可用性.
通过作物消费摄入PFAS带来了风险,水果和蔬菜的可容忍每周摄入量经常超过.

结论:

国内种植的作物,特别是一年菜,可以成为PFAS暴露的重要来源.
靠近工业来源和土壤特征对作物污染有复杂的影响.
消费受污染的本土产品可能会导致超过安全摄入量,造成潜在的健康风险.

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...
