How can construction activities impact indoor air quality?

Construction activities significantly impact indoor air quality, primarily by introducing dust and pollutants into the environment. During construction, materials such as wood, drywall, and insulation are often cut and manipulated, which can release particulate matter into the air. This dust can contain harmful substances like silica, asbestos, or other volatile organic compounds (VOCs) from paints and adhesives used during the process.

Additionally, construction sites often involve the use of heavy machinery and tools that can emit gases and fumes, further deteriorating air quality. Dust and pollutants can irritate respiratory systems, exacerbate asthma and allergies, and pose long-term health risks to occupants and workers.

In contrast, while construction might temporarily enhance ventilation by creating openings, this exposure often does not outweigh the adverse effects of the pollutants introduced. The impacts can also include the alteration of indoor humidity levels, but the primary concern remains the introduction and accumulation of harmful airborne particulates during the construction phase.

Overall, understanding how construction activities can introduce dust and pollutants is crucial for developing appropriate mitigation strategies to protect indoor air quality during and after construction.
