Air pollutants

In 2019, PM₁₀pollution was just slightly lower than in 2018. The reason was changeable weather with periods of participations and high temperature, especially in November and December when no temperature inversions occured. Exceedences of the daily limit values occur especially in the cold part of the year due to heating and meteorological conditions which are extremely unfavourable in winter. In 2019, at two measuring sites PM₁₀ concentration were above the allowed annual number of 35 while annual limit value for PM₁₀ and PM_2,5 was not exceeded.

In Nova Gorica, PM2.5 measurements were established in 2018. In Ljubljana, the PM2.5 mesasurement location changed from Ljubljana Biotechnical Faculty to Ljubljana Bežigrad. From 2018 onward, PM2.5 measurements at the Maribor Center are no longer available.

Goals

EU ambient air quality limit values set by Directive 2008/50/EC for the protection of human health

A limit value for PM_2.5 of 25 µg/m³ as an annual average; in force since 1 January 2015.
A limit value for PM₁₀ of 50 µg/m³ as a daily average, not to be exceeded more than 35 times in a calendar year; in force since 1 January 2005.
An additional limit value for PM₁₀ of 40 µg/m³ as an annual average; in force since 1 January 2005.

WHO Air Quality Guidelines

Annual mean of PM_2.5: 10 µg/m³.
Twenty-four-hour mean of PM_2.5 (99th percentile of the annual daily series (3 days per year)): 25 µg/m³.
Annual mean of PM₁₀: 20 µg/m³.
Twenty-four-hour mean of PM₁₀ (99th percentile of the annual daily series (3 days per year)): 50 µg/m³.
