The ability of the environment to absorb and break down pollutants without significant harm.

Any substance or energy introduced into the environment that has undesired effects, adversely affecting the usefulness of a resource.

A substance that directly enters the environment from a specific identifiable source, like a factory.

Pollution from multiple, diffuse sources, like agricultural runoff or vehicle emissions.

The contamination of air by harmful substances, like gases, particulate matter, and chemicals.

The contamination of water sources by pollutants, making it unsafe or unsuitable for drinking, agriculture, or aquatic life.

The contamination of soil by pollutants, making it less productive and potentially harmful to human health.

The pollution caused by excessive noise levels, which can harm human health and disrupt wildlife.

The introduction of harmful substances into the atmosphere, impacting health, ecosystems and climate.

Substances that directly enter the air from natural events or human activities, like burning fossil fuels or traffic exhaust.

Substances formed when primary pollutants react in the atmosphere, such as smog or acid rain.

Pollutants like carbon monoxide, nitrogen oxides, sulfur oxides, volatile organic compounds, and particulate matter, account for approximately 90% of global air pollution.

Damage to the lungs, heart problems, early death, and developmental issues in children.

Destruction of ecosystems, acidification of rain, and global warming.

Increased healthcare costs, reduced productivity, and damage to buildings.

Contamination of water bodies with substances that harm aquatic life and make the water unsafe for human use.

The maximum amount of pollutants that can be absorbed by an environment without causing harm.

Guidelines set by the Central Pollution Control Board for air quality in India.

The ability of an environment to absorb pollutants through processes like dilution, dispersion, and removal.

Using the assimilative capacity to guide resource allocation, minimizing environmental impact.

The process of setting limits on pollutant concentrations in the air.

Measures to prevent air pollution before it happens, like using cleaner fuels or shifting industries away from cities.

Actions taken to improve air quality after pollution has already occurred, like improving public transport or using renewable energy.
