What kinds of pollutants can construction activities produce?

• A. Dust, noise, and chemicals harmful to the environment and health
• B. Glow, fragrance
• C. Light pollution only
• D. None of the above

Answer: (A)

Construction activities produce a mix of pollutants that affect air, water, and health. Dust from earthmoving, cutting, and grinding includes fine particles like silica that can irritate lungs; noise from equipment and machinery can impact human health and wildlife; and chemicals such as fuels, solvents, paints, sealants, and asphalt emulsions can be toxic if released. Taken together, these pollutants capture the typical environmental threats associated with construction work. The other options don’t fit because glow and fragrance aren’t standard construction pollutants, light pollution is only one narrow aspect and incomplete, and “none of the above” ignores real pollutant types produced by construction.
