Construction activities involve a combination of sources that contribute to air pollution, including exhaust emissions from heavy machinery, dust generated from demolition and excavation, and chemical emissions from paints and solvents used in finishing works.

Construction activities, particularly those involving excavation and demolition, generate significant amounts of particulate matter, which includes dust, smoke, and other small particles that can be harmful to human health when inhaled.

Air quality regulations in construction aim to minimize the release of harmful pollutants into the atmosphere, thereby protecting the health of workers, nearby communities, and the environment from the adverse effects of air pollution.

To effectively control dust emissions, construction sites often employ a combination of measures, including water spraying to suppress dust, wind screens to redirect airflow, and dust collectors to capture and filter particulate matter.

Abatement refers to the removal and proper disposal of hazardous materials, such as asbestos, lead, and mold, from a construction site to ensure the safety of workers and occupants.

The Environmental Protection Agency (EPA) is the primary federal agency responsible for developing and enforcing regulations to protect air quality, including those pertaining to construction activities.

An air quality assessment (AQA) is a study conducted to evaluate the potential air quality impacts of a proposed construction project, considering factors such as emissions from construction activities, nearby air pollution sources, and potential health risks.

Methane (CH4) is not typically emitted by construction equipment as a primary air pollutant. It is primarily associated with natural gas production and distribution, agriculture, and landfills.

Dust control measures in construction aim to minimize the generation and dispersion of dust particles, thereby protecting air quality and reducing the health risks associated with particulate matter inhalation.

Planting trees and vegetation is not a direct method for controlling air pollution from construction activities. While vegetation can contribute to air quality improvement in general, it is not a primary strategy for managing construction-related air pollution.

Air quality monitoring involves the continuous or periodic measurement of air pollutants on a construction site to assess compliance with regulations, evaluate the effectiveness of control measures, and protect the health of workers and the surrounding community.

Sulfur dioxide (SO2) is not typically emitted by paints and solvents used in construction. It is primarily associated with the burning of fossil fuels, particularly in power plants and industrial processes.

Pollution prevention in construction involves implementing measures to minimize or eliminate the generation of air pollutants at the source, rather than relying solely on end-of-pipe control technologies.

Ozone (O3) is not typically emitted directly by diesel-powered construction equipment. It is a secondary pollutant formed in the atmosphere through chemical reactions involving other pollutants, such as nitrogen oxides and volatile organic compounds.
