historic air pollution exposure and long-term health and mortality risks

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. read more

historic air pollution exposure and long-term mortality risks

In one of the longest-running studies of its kind, researchers from Imperial College London have published in the journal Thorax their investigation into the possible effects of long-term air pollution exposure over nearly 40 years on various health outcomes including mortality. read more

expert reaction to study investigating traffic noise and midriff bulge

The relationship between noise generated by traffic and body mass index (BMI), waist circumference and waist–hip ratio was explored in a study published in the journal Occupational & Environmental Medicine. The authors reported that traffic noise was associated with an increase in waist circumference and waist-hip ratio but not BMI, and that combined exposure to more than one type of transport noise increased the risk further. read more
