Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what steps the Government is taking to (a) research and (b) mitigate the potential health risks posed by microplastic exposure to humans.

The UK Health Security Agency, in collaboration with Imperial College, is carrying out research and providing evidence to assist the understanding of the potential risks from exposure to micro and nano plastics through inhalational and oral routes. The potential impact of microplastic materials on human health has been assessed by the UK Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment (COT), who made a number of recommendations for further research. The most recent COT statement was published in 2024. The statements are available at the following link:

Under the 2022/23 UK REACH Work Programme, the Department for Environment Food and Rural Affairs initiated a research proposal to investigate the risks of intentionally added microplastics. The evidence project has reviewed their emissions, and the risks they pose both to human health and the environment. It also included a socio-economic assessment. It will advise on the most effective measures to address any risks and help identify wider evidence gaps that need to be addressed to support a more strategic approach to managing intentionally added microplastics. This project is expected to report in early 2025. The Department for Environment Food and Rural Affairs and the Welsh and Scottish administrations will consider its findings once complete.
