Exposure to air pollution has been associated with numerous health conditions including respiratory diseases, cardiovascular disease, and death. However, investigating the precise impact of air pollution exposure on health outcomes is challenging, particularly when taking historic pollution levels into account. Nonetheless the subject of air pollution, especially in the UK’s major cities, is still a cause of great concern for doctors, policy makers, and the wider population.
In one of the longest-running studies of its kind, researchers from Imperial College London have investigated the possible effects of long-term air pollution exposure over nearly 40 years on various health outcomes including mortality. Published in the journal Thorax, the researchers estimated air pollution levels in England and Wales in 1971, 1981, 1991, and 2001 in a longitudinal study involving nearly 400,000 participants. Due to the changing composition of emissions from industry and transport in the UK over the decades, the researchers measured the levels of several different particulates including black smoke, SO2, and PM10.
