Aggravated because of four developments: Increasing traffic, growing cities, rapid economic development, and industrialization contamination of air by the discharge of harmful substances.
1. Carbon monoxide (CO)
2. Carbon dioxide CO2
3. Chlorofluorocarbons (CFC)
4. Lead
6. Nitrogen oxide (Nox)
7. Suspended particulate matter (SPM)
8. Sulphur dioxide (SO2)
9. Smog
1. Volatile organic compounds
2. Formaldehyde
It is a gas that is emitted naturally by the soil. Due to modern houses having poor ventilation, it is confined inside the house and causes lung cancers.
Ash is produced whenever combustion of solid material takes place.
The use of microorganisms (bacteria and fungi) to degrade the environmental contaminants into less toxic forms. Phytoremediation is use of plants to remove contaminants from soil and water.
A water remediation technique that involves the uptake of contaminants by plant roots. Used to reduce contamination in natural wetlands and estuary areas.
Globalization
Thermal pollution refers to the alteration in the temperature of a natural aquatic environment, either an increase or decrease, induced by human activities. This has emerged as a growing and contemporary environmental concern, driven by the pervasive influence of globalization.
Thermal pollution occurs through practices such as discharging hot water from factories and power plants or clearing trees and vegetation that provide shade to streams, allowing sunlight to elevate water temperatures. Additionally, the release of cold water can have a cooling effect.
Similar to other types of water pollution, thermal pollution spreads, impacting numerous lakes, rivers, and water bodies across different regions of the world.
Power plants generating electricity from fossil fuels utilize water as a cooling agent in industrial facilities, contributing to shoreline deforestation and soil erosion.

Environmental Pollution
Acid rain refers to precipitation that has undergone acidification, resulting from the interaction of sulfur and nitrogen oxides with atmospheric moisture. With a pH below 5.6, acid rain harms ecosystems, particularly lakes, streams, and forests, impacting the flora and fauna residing in these environments.
Acid Rain
"Acid rain" is a comprehensive term encompassing a blend of wet and dry deposition from the atmosphere.
A. Wet Deposition
B. Dry Deposition

Six fundamental steps contribute to the formation of acid rain:
Infertile Soil
A. Soil
B. Vegetation
C. Microorganisms
D. Wildlife
WildlifeE. Humans
F. Acid rain damage on Materials
G. Socio-economic Impacts of Acid Rain: The detrimental effects of acid rain on agriculture and fishing contribute to the degradation of key life quality indicators, including Gross National Product (GNP) and per capita income. This impact is particularly pronounced in predominantly agricultural and developing nations such as India.
