概括
空气中的三胺,游泳池消毒剂的副产品,在许多瑞典游泳池中超过了卫生指南. 度因池类型,白天时间和季节而异,突出显示需要不同的采样策略.
科学领域:
- 环境健康 环境健康
- 职业健康 职业健康 职业健康
- 室内空气质量 室内空气质量
背景情况:
- 三胺是化游泳池中常见的消毒副产品.
- 它可以蒸发到空气中,对游泳者和游泳池工作人员造成刺激.
- 了解空气中的三胺含量对于公共健康和安全至关重要.
研究的目的:
- 为了评估各种室内游泳池类型的空气中三胺度.
- 将这些度与已确定的公共卫生指南进行比较.
- 识别影响三胺水平的因素,如游泳池类型,一天的时间和季节.
主要方法:
- 在瑞典调查了72个室内游泳池,包括运动,教学,冒险和康复游泳池.
- 进行了167次采样,采集了434个空气样本,使用石英过器的活性采样.
- 测量是在游泳池边进行的,重复采样以考虑每天的变化.
主要成果:
- 运动池显示几何平均值 (GM) 为0.12 mg/m3,其中30%超过瑞典指南的0.2 mg/m3.
- 指导和冒险游泳池的GM分别为0.18 mg/m3和0.20 mg/m3.
- 康复池的转基因含量显著降低 (0.03 mg/m3). 在运动/教学游泳池的傍晚和在冷季的康复游泳池中观察到更高的水平.
结论:
- 空气中的三胺含量在不同室内游泳池类型和随着时间的推移而有显著差异.
- 目前的指导方针可能对所有池类型都不够,因为炼池的超标水平表明了这一点.
- 变性需要全面监测,包括重复采样和考虑日间时间和季节性影响,以准确评估暴露.

Chemical Agents for Microbial Control
Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...
Microbial Bioremediation of Pesticides
Pesticides often feature structurally complex chemical architectures, incorporating halogen groups and multiple aromatic rings. These characteristics confer high chemical stability, rendering many pesticides resistant to natural degradation processes. This resistance poses significant environmental concerns, as persistent pesticide residues can accumulate in ecosystems and affect non-target organisms.Despite the inherent stability of many pesticides, certain microorganisms possess the metabolic...
