Types of air pollution
Visit the UK Air website from the Department of Food and Rural Affairs (Defra) for comprehensive information on different types of air pollution, their causes and their effects. You can also view the national air quality forecast and monitoring network.
What are the county, district and borough councils doing about it?
District and borough councils are responsible for assessing and developing plans to address areas where air pollution exceeds national targets.
We've agreed an air quality strategy with the district and borough councils and provided funding to purchase particulate matter (PM 2.5) monitoring equipment across the county.
We're also investigating the feasibility of an air quality alert service for Hertfordshire residents.
