Air pollution is rife in all Scottish cities, with rates breaching key World Health Organisation pollution limits, threatening countless lives.
This news is thanks to an interactive map created by Central Office of Public Interest (COPI), which has exposed the terrible poor air quality faced in the nation's seven cities.
The COPI's charity website addresspollution.org lets the UK public check pollution levels at their postcode and compare it with other parts of the country.
And it is bleak news for the people of Aberdeen, which has been revealed as Scotland's most polluted city, the Scottish Daily Express reports.
The website provides every UK address with air pollution data taken from a national 20m/sq resolution model created by Imperial College London.
Concentrations of PM2.5 (fine particles with a diameter of 2.5 microns or less), PM10 (particles with a diameter of 10 microns or less) and NO2 (Nitrogen Dioxide) are recorded.
According to COPI , PM2.5 can cause asthma, respiratory inflammation and jeopardize lung functions.
PM10 can cause wheezing, bronchitis and reduce lung development while prolonged exposure to NO2 of more than 40mcg can leads to an 11% increased risk of disease related mortality.
It is part of a push to have air pollution levels disclosed to people buying or renting properties.
Aberdeen's Union Street is among the most polluted streets in the whole of the UK, with the map placing it in the 71st out of 99 percentiles across the country.
It is breaching the 10mcg/m3 NO2 limit by over four times with a recorded amount of 42.91mcg/m3. It is also above the 5mcg/m3 limit with a recording of 6.96mcg/m3 and is close to breaching the PM10 limit but falls just under it.
Edinburgh 's Prince's Street records "significant" pollution according to the data. It records a NO2 reading of 31.55 and also exceeds the PM2.5 limits.
Those standing at the 'four corners' junction in Glasgow city centre can expect to experience dangerous levels of PM2.5 and NO2 with the area given a "medium" grading.
Although pollution is considered to be low in Dundee, Stirling, Perth and Inverness, all four breach PM2.5 and NO2 limits.
COPI wants people to use the information provided to "demand action and ask that estate agents and property websites put people before profits by disclosing air pollution levels to renters and buyers at the earliest opportunity".
In 2020, a coroner in England ruled that air pollution had contributed to the death of a nine-year-old girl in London in 2013.
Speaking to the Daily Mail, Professor Sir Stephen Holgate, special advisor on air quality to the Royal College of Physicians, said: "Air pollution is an invisible killer, and because you can't see it it's easy for people to forget and ignore."
"It's essential that the public are given air pollution data for where they are thinking of buying or renting."
