概括
对挥发性有机化合物 (VOC) 的量级控制不足以管理环境和健康风险. 这项研究表明,臭氧形成潜力和毒性加权度是优先考虑电子制造中的VOC排放源的更好的指标.
科学领域:
- 环境化学环境化学
- 工业生态学 工业生态学
- 控制空气污染控制空气污染
背景情况:
- 传统的基于质量的指标不能充分反映与挥发性有机化合物 (VOC) 相关的环境和健康风险.
- 工业环境中的有效风险管理,特别是珍珠河三角洲 (PRD) 的电子制造,需要先进的评估工具.
- 现有的排放清单可能无法准确地反映VOCs的真实影响,因为光化学反应和毒性各不相同.
研究的目的:
- 调查总VOC (TVOC) 质量排放及其臭氧形成潜力 (OFP) 和毒性加权度 (TWC) 之间的关系.
- 评估OFP和TWC作为以来源为导向的指标的有效性,以根据反应性和毒性优先考虑VOC排放来源.
- 在电子制造业中为面向风险的VOC管理策略提供信息.
主要方法:
- 描述了来自东方人民共和国的12个电子制造工厂的26个后处理堆排放量.
- 对VOC物种的分析,然后对每个排放源计算OFP和TWC.
- 统计相关性分析,以评估TVOC质量,OFP和TWC之间的关系.
主要成果:
- 在不同的操作中观察到VOC来源配置文件的显著变化,具有不同的化学特征.
- OFP主要受到高反应性VOCs的一小部分的影响,而TWC显示出高变异性,微量有毒物种的贡献不成比例.
- 在TVOC质量,OFP (中等相关性,R2=0.46) 和TWC (没有显著相关性,R2<0.11) 之间发现了系统的脱.
结论:
- 基于大规模的VOC控制策略是有限的,可能无法有效解决环境和健康风险.
- OFP和TWC是识别高影响VOC排放源的关键指标,需要特定于操作的缓解方法.
- 该研究为完善排放库存和制定针对风险为基础的VOC管理的有针对性的监管策略提供了基础.

Effects of Chemicals: Overview
2.4K
Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...

Oxygen Requirements and Growth Patterns
2.1K
Microorganisms exhibit diverse oxygen requirements and growth patterns driven by their metabolic strategies and environmental adaptations. Oxygen, while essential for many organisms, can also be toxic under certain conditions, shaping how microorganisms grow and survive.Oxygen Requirements of MicroorganismsMicroorganisms are classified based on their ability to use or tolerate oxygen:● Obligate aerobes like Mycobacterium tuberculosis need oxygen for energy production, as it serves as the...

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...

Toxic Reactions: Overview
3.5K
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Chemical Factors Affecting Respiration Centers
2.7K
Chemical factors such as changing CO2, O2, and H+ levels in arterial blood play a critical role in influencing respiration depth and rates. These variations are detected by chemoreceptors—specialized sensors located in two primary body areas. Central chemoreceptors are found throughout the brain stem, including the ventrolateral medulla, while peripheral chemoreceptors are located in the aortic arch and carotid arteries.
