The emissions of pollutants into the atmosphere of Thessaloniki are due to the following factors: road transport is the main source of nitrogen oxides (NOx) and carbon monoxide (CO). What is the chief source of air pollution in Thessaloniki? Many factories and non-essential production units were also required to close which removed their emissions from the atmosphere. An improvement was seen in 2020 when the figure was 20.9 µg/m³, however, this reading may have been affected by the COVID-19 situation as many vehicles were no longer in daily use because the offices were closed, in an attempt to halt the spread of the virus. Records for air pollution were first held in 2019 when a figure of 23.3 µg/m³ was recorded. Out of these months, the best was May with a reading of 13 µg/m³, the worst was November with a reading of 29.4 µg/m³. The remaining ten months of the year saw figures from the “Moderate” category with readings between 12.1 and 35.4 µg/m³. The month of January saw figures from the “Unhealthy for sensitive groups” category with a figure of 40.1 µg/m³. Looking back at the figures for 2020, released by, it can be seen that the month with the best quality air was June with a figure of 11.8 µg/m³ which is classed as being “Good”. Does the level of air pollution vary throughout the year in Thessaloniki?Īir quality is very volatile as it is subject to many external influencing factors such as meteorological and atmospheric changes. For up-to-date information about air quality, there is an app available from AirVisual which is downloadable for all mobile devices. Those of a sensitive disposition should limit their time spent outside and should always wear a good quality face mask when doing so.

When the level of air pollution is classed as “Moderate”, the given advice would be to remain indoors as much as possible, closing all doors and windows to prevent the ingress of more polluted air. Although no amount of air pollution is considered to be safe. This level of PM2.5 is almost twice the recommended safe level of 10 µg/m³ as suggested by the World Health Organisation (WHO) as being an acceptable level. The only pollutant measured in Thessaloniki was PM2.5 which was 18.8 µg/m³. If data is unavailable for all 6 pollutants, a figure can still be calculated by using what figures there are. It can then be used as the metric when comparing air quality in other cities around the world. This United States Air Quality Index number is calculated using the levels of six of the most commonly occurring air pollutants, such as nitrogen dioxide, sulphur dioxide, ozone, carbon monoxide and both sizes of particulate matter, which are PM2.5 and PM10. Towards the end of 2021, Thessaloniki was experiencing a period of “Moderate” air quality with a US AQI reading of 65. It is Greece’s second major economic, industrial, commercial and political centre as well as a major transportation hub. According to a survey conducted in 2011, Thessaloniki had an estimated population of over 824,000 people in the urban area and over another million in the metropolitan area. Thessaloniki, also known as Thessalonica in English, Saloniki or Salonica is the second-largest city in Greece. But if you look at a long run of days, on which the Met Office said the probability of rain was 80%, you’d expect it to have rained on about 80% of them.What is the current level of air pollution in Thessaloniki? If it doesn’t rain in your garden tomorrow, then the 80% forecast wasn’t wrong, because it didn’t say rain was certain. ‘In weather forecasting, suppose the Met Office says that the probability of rain tomorrow in your region is 80%…wat they are saying is there is an 80% chance of rain occurring at any one place in the region, such as in your garden. The Met Office have gone into further detail on their website, explaining the probability of rain when viewed in a percentage form. ‘So if you’ve got the Met Office app, that’s one less thing to worry about mind unblown.’ There are different ways of expressing percentages and in the USA they do use the area one, but generally not here in the UK. ‘So 60 per cent means a 60 per cent chance of rain, 40 per cent chance of dry. That percentage doesn’t mean how much of your area can expect rain (Picture: .uk)
