Vehicle emissions, particularly from diesel engines, are a major contributor to air pollution in urban areas due to the release of particulate matter, nitrogen oxides, and hydrocarbons.

Sulfur dioxide, released during the combustion of fossil fuels, is a major contributor to acid rain as it reacts with water vapor in the atmosphere to form sulfuric acid.

Air purification refers to the process of removing contaminants and pollutants from the air, typically using various technologies such as filtration, absorption, and chemical reactions.

Ozone, formed through the reaction of sunlight with nitrogen oxides and volatile organic compounds, is a major component of smog and is associated with respiratory issues and environmental damage.

Emission reduction refers to the strategies and measures taken to minimize the release of pollutants into the atmosphere, aiming to improve air quality and reduce environmental impacts.

Carbon dioxide, released during the combustion of fossil fuels and various industrial processes, is the primary greenhouse gas responsible for trapping heat in the atmosphere and contributing to global warming.

Air quality standards are legally enforceable limits set by regulatory agencies to ensure that the concentration of pollutants in the air does not exceed levels that pose a risk to human health and the environment.

Chlorofluorocarbons (CFCs), once widely used in refrigeration, aerosols, and foam blowing agents, are potent ozone-depleting substances that contribute to the destruction of the stratospheric ozone layer.

Air quality monitoring involves the collection and analysis of data on air pollutants to assess the levels and trends of air pollution, identify sources, and evaluate the effectiveness of air quality management strategies.

Photochemical smog is formed through the reaction of nitrogen oxides and volatile organic compounds (VOCs) in the presence of sunlight, leading to the production of ozone and other secondary pollutants.

Air quality management involves the development and implementation of strategies, policies, and measures to improve air quality, reduce air pollution, and protect public health and the environment.

Particulate matter, especially fine and ultrafine particles, can penetrate deep into the lungs and cause respiratory issues such as asthma, bronchitis, and other health problems.
