Question to the Department of Health and Social Care:

To ask His Majesty's Government what assessment they have made of the research published by PSE Healthy Energy and Stanford University in Environmental Research Letters on 25 March on the harmfully high levels of benzene measured in UK homes emitted by gas cooktops.

The UK Health Security Agency (UKHSA) has noted the published research but has not made a full assessment of the study, which is based on a small number of stoves. Currently, there are limited studies that have investigated benzene concentrations in United Kingdom homes. Further research is needed to better understand exposure to indoor air pollutants and the effects on health.

Reducing emissions of pollutants and ensuring adequate ventilation within indoor environments are important. The UKHSA continues to consider and evaluate the evidence of exposure to indoor air pollutants and the potential health effects.
