概括

建筑材料在水中释放诸如uron之类的生物制剂,因此需要识别来源以符合监管要求. 制造商没有列出一些生物制剂,这突显了需要进行更广泛的调查的需要.

科学领域:

环境化学环境化学
材料科学材料科学材料科学
生态毒理学生态毒理学

背景情况:

建筑材料中的杀菌剂防止生物生长,但可以入水体.
准确识别生物制剂来源对于监管合规 (例如,欧洲生物制药条例) 至关重要.
降水可以从经过处理的表面调动生物制剂,导致环境污染.

研究的目的:

调查各种生物制剂和化学元素从常见建筑表面材料中的浸出情况.
为了确定从经过处理的材料中产生的生物污染的具体来源.
在标准化实验室条件下评估生物制剂的释放率.

主要方法:

实验室规模的浸实验使用15种不同的建筑材料 (例如,屋顶料,带,浸木材,油漆).
标准方法SIS-CEN/TS 16637-2:2015的应用.
在液体与表面面积比为22.5L/m2的情况下进行测试,采样时间为6h,18h和5天,并更新液.

主要成果:

在测试材料中,迪乌龙是最频繁检测到的生物杀伤剂,特别是在木漆中.
木制涂料显示出最多种类的杀菌剂,包括二和其降解产品 (DCPU,DCPMU),丁,碳胺和单.
在浸木材的液中始终发现铜;一些释放的生物制剂并未由制造商声明.

结论:

生物制剂从建筑材料中的浸出是环境释放的重要途径.
制造商的数据表可能不完全代表生物制剂含量,需要更广泛的分析方法.
由于生物制剂法规和产品开发的不断变化,持续监测和来源识别至关重要.

Bioremediation

Bioremediation

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.

Biological Methods for Microbial Control

Biological Methods for Microbial Control

Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...
