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

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

The modern CFC-free aerosols still emit the volatile organic compounds (VOCs), which still affect the ozone and the environment. The VOCs are the primary component of the asthma-inducing smog. Besides, the propellants in aerosol cans are highly flammable when in contact with fire and can cause explosions and start fires.

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

Ozone damages plants by entering leaf openings called stomata and oxidizing (burning) plant tissue during respiration. This damages the plant leaves and causes reduced survival. Many factors can increase the amount of ozone injury such as soil moisture, presence of other air pollutants, insects or diseases, and other environmental stresses.

10/19 · Photolysis of oxygenated volatile organic compounds (OVOCs) produces a primary source of free radicals, including OH and inorganic and organic peroxy radicals (HO₂ and RO₂), consequently increasing photochemical ozone production. The amplification of radical cycling through OVO

Some VOCs react slowly and changes in their emissions have limited effects on local or regional ozone pollution episodes. Those VOCs, determined to have low photochemical reactivity by approved test methods, may be excluded as VOC for regulatory purposes. These determinations are made by regulation and are commonly referred to as VOC Exemptions.

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

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 associated sectors that dominate OFP and SOAP and

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., ).
