Construction sites are often a sign of growth and development, but they can also be significant sources of air pollution. One of the most overlooked pollutants from these sites is construction dust, also known as particulate matter (PM). This dust, created by activities such as demolition, excavation, and the movement of materials, poses serious risks to both human health and the environment.
Why Is Construction Dust a Problem? Construction dust contains fine particles, including materials such as silica and heavy metals. These particles are small enough to be inhaled, potentially causing respiratory problems, heart disease, and long-term health issues, particularly for site workers and people living nearby. From an environmental perspective, uncontrolled dust emissions can lower air quality, damage plant life, and contribute to broader pollution problems. In built-up areas, dust can also lead to complaints, regulatory breaches, and costly delays for construction projects.
The Importance of Assessment and Control Assessing dust emissions early in the planning stage helps identify high-risk activities and areas. This allows project teams to design and implement effective dust control measures before work begins on site.
The Institute of Air Quality Management (IAQM) provides detailed guidance on how to carry out these assessments. The latest version, Guidance on the Assessment of Dust from Demolition and Construction – January 2024, outlines a step-by-step method to evaluate dust risks and determine appropriate mitigation measures.
Viridian Air applies this guidance to assess the dust emissions and develop appropriate dust management plans. More details at https://viridianair.co.uk/services/
Common control methods include:
- Damping down surfaces to reduce dust
- Using extraction systems and physical barriers
- Covering lorries when transporting materials
- Regular air quality monitoring in and around the site
These steps are not only best practice but are often required by local regulations to protect both workers and nearby communities.
