Air Pollution: Health Hazards

Question for Department of Health and Social Care

UIN HL4695, tabled on 19 May 2020

To ask Her Majesty's Government what assessment they have made of the impact of human exposure to high levels of ultrafine particulate matter from air pollution on the expression of Angiotensin I converting enzyme 2.

Answered on

Public Health England (PHE) is aware of evidence linking exposure to particulates in the air to altered expression of Angiotensin I converting enzyme 2 (ACE2), and of emerging evidence that this is a potential mechanism by which air pollution exposure could theoretically increase the spread or severity of COVID-19.

PHE is continuously reviewing and considering the evidence on the health impacts of air pollution exposure, as well as potential associations between air pollution and the health impacts of COVID-19.
