概括
有机酸 (OPEs) 存在于建筑和拆除废物 (CDW) 垃圾填埋场. 改进CDW管理对于防止这些阻燃剂和增塑剂对环境造成污染至关重要.
科学领域:
- 环境化学环境化学
- 环境科学 环境科学
- 废物管理 废物管理
背景情况:
- 有机酸 (OPEs) 作为各种消费品和工业产品的阻燃剂和增塑剂被广泛使用.
- 建筑和拆除废弃物 (CDW) 的废弃物管理实践不足可能导致OPE的环境释放.
研究的目的:
- 调查来自巴西CDW垃圾填埋场的土壤样本中OPE的存在和度.
- 评估OPE在CDW对环境污染的影响.
主要方法:
- 从邻近CDW惰性垃圾填埋场的地区采集了土壤样本.
- 使用气体染色学与质谱学 (GC-MS) 结合,对OPE进行了分析.
主要成果:
- 在所有分析的土壤样本中,在可量化的度 (21251 ng g-1) 中检测到OPE.
- 确定的特定OPE化合物包括三烯酸盐,三二乙烯酸盐和其他物质.
- OPE的存在归因于CDW中危险材料的控制和选缺乏.
结论:
- 目前的法规不将OPE归类为受管制物质,导致它们在CDW中不受控制地存在.
- 需要加强CDW管理策略,包括采样和选,以减轻OPE环境污染.
- 显然需要改进废物管理协议,以尽量减少CDW的OPE对环境的影响.

Anticholinesterase Agents: Poisoning and Treatment
918
Anticholinesterases, also known as cholinesterase inhibitors, work by blocking the breakdown of acetylcholine, leading to its accumulation in the synaptic cleft. This accumulation indirectly enhances both muscarinic and nicotinic actions. These agents are classified as reversible or irreversible based on their mechanism of action.
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is...

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
