WebVolatile Organic Compounds, or VOCs, are organic chemicals that evaporate into the atmosphere at room temperature. Some VOCs can also dissolve into groundwater. They … WebPhotochemical smog, which can be found in cities, is a kind of air pollution caused by vehicle emissions and industrial gases. These pollutants react within the sunlight and in the atmospheres to the produce as secondary pollutants, which are mixed with primary emissions to create photochemical smog. When fuel is burned at high temperatures ...
WebFor example, VOCs react with nitrogen oxides to form ozone and ultra fine particles, a component of smog that affects human health, vegetation and climate (WMO, 2024). Measurements and global modelling show that surface ozone levels exceed recommended limits in many parts of the world, especially in Asia (Figure 1). WebPhotochemical smog is made up of various secondary pollutants like ozone, peroxyacyl nitrates (PANs), and nitric acid (seen in Figure 2). Different types of secondary pollutants include: [2] Ozone (O 3) Sulfuric acid and nitric …
WebVolatile organic compounds (VOCs) play an important role in atmospheric chemistry. Primary VOCs take part in chemical and photochemical reactions, contributing to ozone (O3) and secondary organic aerosol (SOA) formation, which may cause air pollution problems. High VOC concentrations might lead to dizziness, nausea, headaches, genotoxicity, … WebFeb 13, 2024 · Smog is a common bilden of ventilate pollution found mainly in urban areas and large population locations. The concepts refers to any type of atmospheric pollution—regardless a source, composition, or …
WebPhotochemical and chemical reactions involving ozone drive many of the chemical processes that occur in the troposphere by day and by night. At abnormally high concentrations (the largest source being emissions from combustion of fossil fuels), it is a pollutant, and a constituent of smog.
