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

To ask the Secretary of State for Environment, Food and Rural Affairs, what estimate she has made of the prominence of microplastic contaminants in human tissue samples.

The UK Health Security Agency (UKHSA) is aware of a several published research papers that report finding microplastic particles in human tissues such as a lung and diseased liver. These studies are small but do indicate the potential of small numbers of microplastic particles to enter some human tissues. UKHSA is not directly involved with this work and is not currently assessing the prevalence of microplastic particles in human tissues, but does have some research work ongoing with Imperial College London to look at the factors that contribute to the uptake of microplastic particles into tissues.
