To ask the Secretary of State for Health and Social Care, what assessment he has made of the potential risk of microplastic pollution to human health; and what practices he has in place to continuously evaluate the growing body of research on this topic.

The UK Health Security Agency is carrying out research to understand if there are potential health risks from exposure to micro and nano plastics through inhalational and oral routes, as part of the National Institute of Health and Care Research (NIHR) funded Health Protection Research Unit in Environmental Exposures and Health.

In addition, 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. The most recent statement was published in 2024 and is 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. This project is expected to report in early 2025. The Department for Environment Food and Rural Affairs and the Welsh and Scottish Governments will consider its findings once complete.
