Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment she has made of the potential impact of microplastics in the air within (a) houses, (b) large cities, (c) hospitals and (d) health care environments.

The Environment Agency undertakes a range of ambient air quality monitoring on behalf of Defra including particulate matter monitoring. Particulate matter is a complex pollutant that could include some proportion of microplastics but this is not routinely assessed. Near real time data on particulate matter levels, as well as other pollutants, are made available on UK Air website.
