One of the most harmful air pollutants are volatile organic compounds (VOCs), which can be evaporated and transport to atmosphere at ambient conditions. Such materials have been making many

Layers, Photodissociation, Abstract Photolysis of oxygenated volatile organic compounds (OVOCs) produces a primary source of free radicals, including OH and inorganic and organic peroxy radicals (HO 2 and RO 2 ), consequently increasing photochemical ozone production.

2022/6/24 · Plants emit a broad number of Biogenic Volatile Organic Compounds (BVOCs) that can impact urban ozone (O3) production. Conversely, the O3 is a phytotoxic pollutant that causes unknown alterations in BVOC emissions from native plants. In this sense, here, we characterized the constitutive and O3-induced BVOCs for two (2dO3) and four (4dO3) days of

In China, emissions of ozone (O3)-producing pollutants have been targeted for mitigation to reduce O3 pollution. However, the observed O3 decrease is slower than/opposite to expectations affecting the health of millions of people. For a better understanding of this failure and its connection with anthropogenic emissions, we quantify the summer O3 trends that would have occurred had the weather

2022/6/30 · Volatile organic compounds (VOCs) emissions have become a key environmental concern due to adverse effects on health and environment 1,2,3,4.Extended human exposure to VOCs emissions (e.g

Wakamatsu, S.; et al. Vertical distribution of ozone and VOCs in the low boundary layer of Mexico City. Atmos. Chem. Phys volatile organic compounds and their applications within the

Ambient volatile organic compounds (VOCs) were continuously measured from February to October at an urban site in Wuhan. The characteristics and sources of VOCs and their effect on ozone (O3) formation were studied for the first time. The total VOC levels in Wuhan were relatively low, and

1/15 · Ambient volatile organic compounds (VOCs) were continuously measured from February to October at an urban site in Wuhan. The characteristics and sources of VOCs and their effect on ozone (O3) formation were studied for the first time. The total VOC levels in Wuhan were relatively low, and

In our present study we tested the health effects among women of controlled exposures to volatile organic compounds (VOCs), with and without ozone (O3), and psychological stress. Each subject was exposed to the following three conditions at 1-week intervals (within-subject factor): VOCs (26 mg/m3), VOCs + O3 (26 mg/m3 + 40 ppb), and ambient air with a 1-min

Assessing the role of volatile organic compounds (VOCs) in production of ozone and secondary organic aerosol (SOA) is especially important in light of ongoing policy goals. Here, we estimated the ozone formation potential (OFP) and SOA formation potential (SOAP) of anthropogenic and biogenic VOC emissions to evaluate (1) anthropogenic VOCs and

Effect of Volatile Organic compounds (VOCs) such as benzene, toluene, ethylbenzene, xylene and other hazardous volatile organic materials on the ozone layer by studying the advantages and disadvantages of this material upon the production of ozone by NOx gases. The rate of reaction, selectivity and optimum concentration of VOCs which can be used to protect the ozone layer and maximize the
