Air Pollution and Risk
* Select the correct answer into all dropdown fields. You need to answer all questions before clicking verify button.
Studies have found that to air pollution is linked to a greater risk of depression and suicide. While the effects on the body from breathing dirty air are well-established, an emerging body of research has suggested pollution may also affect mental health. Isobel Braithwaite at University College London and her colleagues looked in at 25 studies published up to late 2017, for a meta-analysis on the links between the two. They found that someone living for at least six months in an area with twice the World Health Organization’s recommended limit for fine particulate matter, PM2.5, would have roughly a 10 percent risk of developing depression as a person living in an area that met the limit. The WHO’s guideline is that PM2.5s shouldn’t 10 micrograms per cubic metre of air (μg/m3) on average over a year. This is the average level in the UK. In London the average figure is higher at 13.3μg/m3, and in Delhi it is around 133μg/m3.
