The causes of air pollution in urban areas include:
1. Vehicular emissions: Cars, trucks, and buses release harmful gases like CO, NOx, and particulate matter (PM).
2. Industrial activities: Factories, power plants, and construction sites emit pollutants like SO2, NOx, and PM.
3. Fossil fuel combustion: Burning of fossil fuels like coal, oil, and gas for energy and heating releases pollutants like PM, SO2, and NOx.
4. Waste disposal: Improper waste management, like open burning of trash, releases toxic chemicals into the air.
5. Construction and demolition: Building activities release dust and particulate matter into the air.
6. Agricultural activities: Urban farming and gardening can release pesticides, fertilizers, and other harmful chemicals into the air.
7. Population growth: Increased population density leads to higher energy consumption, vehicle usage, and waste generation, contributing to air pollution.
8. Poor urban planning: Inadequate green spaces, narrow streets, and high-rise buildings can trap pollutants in urban areas.
9. Climate change: Temperature increases and weather pattern changes can exacerbate air pollution in urban areas.
These causes of air pollution in urban areas can have harmful effects on human health and the environment, making it essential to implement effective mitigation strategies.
