Committee on the Medical Effects of Air Pollutants

Committee on the Medical Effects of Air Pollutants (COMEAP) advises the government on all matters concerning the health effects of air pollutants.

Role of the group

COMEAP provides independent advice to government departments and agencies on how air pollution impacts on health. Its members come from a range of specialist fields such as air quality science, atmospheric chemistry, toxicology, physiology, epidemiology, statistics, paediatrics and cardiology. There is also a lay member, who helps ensure that the general public can access and understand the committee’s work.
