Observation of volatile organic compounds (VOCs), NO 2 and O 3 with high temporal resolution was conducted in Chengdu to investigate the chemical processes and causes of high O 3 Characteristics of volatile organic compounds, NO 2 , and effects on ozone formation at a site with high ozone level in Chengdu

the major O3 precursors, volatile organic compounds (VOCs) could contribute to the formation of O3 through a series of photochemical reactions, including the hydroxyl radical (OH) initiated oxidation of VOCs, nitrogen cycling driven by peroxyl (RO2) and hydroperoxyl (HO2) oxidation and photolysis, and the combination of oxygen atom (O) with

2022/6/27 · Impact of Biogenic Volatile Organic Compounds Emission on Ozone Air Quality in the Sichuan Basin Previous studies have suggested that severe O 3 pollution over China in the year of is in large part due to protracted unfavorable meteorology (featured by hot and stagnant weather conditions) and climate-driven elevated BVOC emissions ( Wu et al., ).

2022/8/24 · Known as tropospheric or "ground-level" ozone, this gas is harmful to human heath and the environment. Since it forms from emissions of volatile organic compounds (VOCs)

2022/7/7 · The effects of ozone on individual plants can then have negative impacts on ecosystems, including: loss of species diversity (less variety of plants, animals, insects, and

3/15 · oxide gases (NOx) and volatile organic compounds (VOC) are released into the air. During the warm, sunny days of spring "Health and Environmental Effects of Ozone Layer Depletion

The impact of volatile organic compounds on ozone formation in the suburban area of Shanghai Kun Zhang a, b, Li Li a, b, *, Ling Huang a, b, Yangjun Wang a, b, Juntao Huo c,

VOCs are a group of carbon-based chemicals that easily evaporate at room temperature. Many common household materials and products, such as paints and cleaning products, give off VOCs. Common VOCs include acetone, benzene, ethylene glycol, formaldehyde, methylene chloride, perchloroethylene, toluene and xylene. Different VOCs have different health effects, and range

Chengdu is a megacity in the southwest of China with high ozone (O 3) mixing ratio.Observation of volatile organic compounds (VOCs), NO 2 and O 3 with high temporal resolution was conducted in Chengdu to investigate the chemical processes and causes of high O 3 levels. The hourly mixing ratios of VOCs, NO 2, and O 3 were monitored by an online system from 28 August to 7 October, 2016.
