Hans Peter H Arp
Persistent and mobile organic substances are those with the highest propensity to be widely distributed in groundwater and thereby, when emitted at low-levels, to contaminate drinking water extraction points and freshwater environments. To ...
Elucidating the Role of O2 Uncoupling in the Oxidative Biodegradation of Organic Contaminants by Rieske Non-heme Iron Dioxygenases [0.03%]
揭秘Rieske非血红素铁氧还酶解降有机污染物过程中氧气解耦作用机制及其在氧化生物降解中的角色
Charlotte E Bopp,Nora M Bernet,Hans-Peter E Kohler et al.
Charlotte E Bopp et al.
Oxygenations of aromatic soil and water contaminants with molecular O2 catalyzed by Rieske dioxygenases are frequent initial steps of biodegradation in natural and engineered environments. Many of these non-heme ferrous iron enzymes are kno...
Plastic Burning Impacts on Atmospheric Fine Particulate Matter at Urban and Rural Sites in the USA and Bangladesh [0.03%]
美国和孟加拉国城市和农村地区塑料燃烧对大气细颗粒物的影响

Md Robiul Islam et al.
To better understand the impact of plastic burning on atmospheric fine particulate matter (PM2.5), we evaluated two methods for the quantification of 1,3,5-triphenylbenzene (TPB), a molecular tracer of plastic burning. Compared to tradition...
Financial Viability and Environmental Sustainability of Fecal Sludge Treatment with Pyrolysis Omni Processors [0.03%]
粪便污泥热解处理的 Omni 处理器的经济可行性和环境可持续性分析
Lewis Stetson Rowles,Victoria L Morgan,Yalin Li et al.
Lewis Stetson Rowles et al.
Omni Processors (OPs) are community-scale systems for non-sewered fecal sludge treatment. These systems have demonstrated their capacity to treat excreta from tens of thousands of people using thermal treatment processes (e.g., pyrolysis), ...
Changes in Ozone Chemical Sensitivity in the United States from 2007 to 2016 [0.03%]
2007至2016年美国地面臭氧化学敏感度变化

Shannon Koplitz et al.
Anthropogenic nitrogen oxide (NOx) and volatile organic compound (VOC) emissions in the U.S. have declined substantially over the last decade, altering the NOx-VOC chemistry and ozone (O3) production characteristics of many areas. In this w...
Electrospun Nanofibrous Membranes for Controlling Airborne Viruses: Present Status, Standardization of Aerosol Filtration Tests, and Future Development [0.03%]
静电纺纳米纤维膜控制空气传播病毒的研究现状、气溶胶过滤测试标准化及未来发展方向
Hongchen Shen,Minghao Han,Yun Shen et al.
Hongchen Shen et al.
The global COVID-19 pandemic has raised great public concern about the airborne transmission of viral pathogens. Virus-laden aerosols with small size could be suspended in the air for a long duration and remain infectious. Among a series of...
Effects of Acidity on Reactive Oxygen Species Formation from Secondary Organic Aerosols [0.03%]
酸度对二次有机气溶胶反应性氧氮物种形成的影响
