Live Pollution Monitor

Data from a pollution monitor located on Warrender Park Road near the High School, measuring particulate pollution (PM10, PM2.5). Particulate pollution is commonly caused by Diesel engines, woodburning stoves, and motor vehicle brake- and tyre- wear dust.

Currently, the World Health Organisation identifies safe levels of PM10s (particulates measuring under ten micrometres) as under 15µg/m³ (micrograms per cubic metre) annual average and no more than 45µg/m³ averaged over 24 hours.

For PM2.5s (particulates measuring under 2.5 micrometres) there are no safe levels, the recommendation is no more than 5µg/m³ annual average and no more than 15µg/m³ averaged over 24 hours.

PM10s are implicated in causing asthma and PM2.5s can even enter the bloodstream via the lungs due to their small size.

    BBC Article:

    Air pollution is even more dangerous than previously thought, the World Health Organization (WHO) has warned

    New guidelines, released in September 2021, halve the recommended maximum for exposure to tiny particles called PM2.5s.

    It is also cutting the recommended limit for another class of microparticles, known as PM10s, by 25%

    Herald Article:

    There is no safe amount of tiny particles called PM2.5s that are pumped into the atmosphere by traffic and industry.

    An analysis identified several new causes of hospital admissions linked to small increases in particulate matter, such as sepsis and kidney failure. Others included urinary tract and skin infections.

    This was on top of established ones such as heart and lung conditions, Parkinson’s disease and diabetes.

    Evening News article:

    More than one in 29 deaths are caused by air pollution here [in Edinburgh], with 157 deaths being directly linked to the pollutant PM2.5.

    These terrifying figures make it clear that we must be taking fast and direct action to tackle pollution in our city. The council’s City Mobility Plan includes a number of initiatives to reduce the need for private car use.
