概括

酸脱酶抑制剂 (SDHI) 杀菌剂在全球范围内污染水生环境. 二甲对生态构成高风险,需要限制SDHI的使用和进一步的"一健康"风险评估.

科学领域:

环境化学环境化学
生态毒理学生态毒理学
风险评估风险评估

背景情况:

酸脱酶抑制剂 (SDHI) 是全球检测到的流行真菌杀菌剂.
它们在水生环境中的广泛存在引发了对生态毒性的担忧.
关于SDHI污染和生态风险的数据是分散的,阻碍了全面的评估.

研究的目的:

整合来自不同水生环境的SDHI残留数据.
对SDHIs进行全球范围的水生生态风险评估.
确定构成最大生态风险的SDHI,并了解影响其毒性的因素.

主要方法:

从六大洲的194个水生环境到2024年6月编制的残留数据.
分析了20个SDHI,重点关注经常检测到的化合物,如博斯卡利德和弗拉图拉尼尔.
采用物种间相关性估计-物种敏感度分布 (ICE-SSD) 模型进行风险评估.
与SDHI物理化学性质相关的水生生态毒性 (log Kow,可溶性,pKa).

主要成果:

SDHI污染和度在各大陆和基质 (水,沉积物,生物) 上有很大的差异.
二二二烯表现出最低的LC50 (3.5μg/L),表明度高于0.035μg/L的高风险.
弗卢托利尼尔对8种水生生态系统构成高风险,对5种水生生态系统构成中等风险;博斯卡利德对1种水生生态系统构成中等风险.
SDHI生态毒性与它们的物理化学特性有显著的相关性.

结论:

SDHI污染对全球水生生态系统构成重大生态风险.
某些特定的SDHI,如二二皮尔 (benzovindiflupyr) 和弗拉图拉尼尔 (flutolanil),需要立即管理风险.
建议在"One Health"框架内限制SDHI的使用和综合风险评估.

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...
