Photochemical Smog

A type of air pollution formed from VOCs + O3 (Ozone), which irritates eyes and lungs.

Thermal Inversion

A meteorological phenomenon where warm air traps cooler air below, leading to pollution accumulation.

Indoor Air Pollutants

Common air pollutants found indoors, including CO, VOCs, Radon, and PM.

Reducing Air Pollutants

Methods include fossil fuel conservation and employing technology such as electrostatic precipitators, scrubbers, and catalytic converters.

Acid Rain

Rain that forms when NOx and SOx combine with water vapor in the atmosphere, harming ecosystems, plants, animals, statues.

Noise Pollution

Sound levels that induce stress and hearing loss, affecting wildlife behavior - mating, hunting, migration.

Catalytic Converter

Device in cars designed to reduce harmful pollutants like 2NO + 2CO } 1N2 N+2C
