Ozone
Ozone Ozone (O₃) is a gas formed in the atmosphere through chemical reactions between volatile organic compounds (VOCs) and nitrogen oxides (NOₓ) in the presence of sunlight. It plays a dual role in the environment: in the stratosphere, ozone forms the ozone layer, which protects life on Earth by absorbing harmful ultraviolet radiation. However, at…

Fine Particulate Matter
Fine Particulate Matter Fine particulate matter are microscopic particles suspended in the air, known as aerosols. PM10 includes particles smaller than 10 micrometers, and PM2.5 refers to those under 2.5 micrometers. These particles originate from human activities (e.g., industry, transport, agriculture) and natural sources (e.g., wildfires, volcanic eruptions) or form through chemical reactions in the…

Volatile Organic Compounds
Volatile Organic Compounds Volatile Organic Compounds (VOCs) are organic chemicals that easily vaporize into the air at room temperature, contributing significantly to air pollution. VOCs include such compounds as methane, benzene, xylene, propane and butane. VOCs are emitted by various sources, including industrial processes, transportation, and agriculture (ruminants and cultivation). They play a major role…

Sulfur oxides
Sulfur oxides Sulfur oxides (SOx), primarily sulfur dioxide (SO₂), are gases produced mainly by burning fossil fuels and certain industrial processes. They contribute to air pollution, acid rain, and respiratory issues when released into the atmosphere and can react with water vapor to form sulfuric acid, damaging ecosystems and infrastructure.
