One type of construction pollution that can be reduced by prevention activities is airborne dust generation.
Airborne dust can be generated by various construction activities, such as excavation, demolition, grading, hauling, and vehicle traffic. Airborne dust can have negative impacts on the air quality, human health, and climate. Airborne dust can contribute to respiratory problems, allergies, asthma, and eye irritation for workersand nearby residents. Airborne dust can also reduce the visibility, increase the risk of accidents, and damage the equipment and materials. Airborne dust can also affect the climate by absorbing or reflecting solar radiation, altering the cloud formation and precipitation patterns, and influencing the carbon cycle1.
Some of the prevention activities that can reduce airborne dust generation during construction are12:
* Covering or wetting the exposed soil and stockpiles
* Using water sprays or misters to suppress the dust
* Installing wind fences or barriers around the site
* Applying mulch, straw, or vegetation to stabilize the soil
* Sweeping or vacuuming the paved areas and roads
* Limiting the speed and frequency of vehicles
* Using low-emission or electric vehicles and equipment
* Implementing a dust control plan and monitoring the dust levels
