[ZR15] Emissions of particulate matter

19.10.2022

The emission of primary particles, smaller than 10 µm (PM₁₀), particles smaller than 2.5 µm (PM_2.5) and all total suspended particles (TSP) have decreased in the period 2000 – 2020 in Slovenia by 28 %, 30 % and 26 %. The main source of emissions of particulate matter are households, mainly due to use of biomass for domestic heating.

[ZR16] Sulphur content of fuels

A decrease in SO₂ emissions has been significantly influenced by the tightening of legislation concerning the concentration of sulphur in liquid fuels. The permitted concentrations of sulphur in fuels were not exceeded in 2012.

Concentrations of metals in the ambient air in Slovenia do not exceed the prescribed limits. The annual target value for benzo ( a) pyrene was exceeded at the sampling points in Ljubljana and Maribor, which are under the influence of emissions from transport.

[ZR18] Effects of ozone on vegetation

15.07.2016

In recent years, air pollution with ozone has been above the target value at all measurement sites representative for vegetation. Furthermore, the long-term target value has been exceeded to an even higher degree.

[ZR19] Health costs of air pollution in European cities and the linkage with transport

30.04.2021

Air pollution is the most important environmental risk factor for human health, affecting an average of 400,000 premature deaths in the EU and costing Europeans an average of more than € 166 billion a year. In the case of the cities of Ljubljana and Maribor, external costs amount to almost EUR 271 million annually. Estimation of external costs of air pollution from transport is slightly decreasing.

[ZR20] Investments in air pollution mitigation measures

22.04.2021

Plans to improve air quality in Slovenia include a number of measures. It is crucial that the state ensures the financing of measures and thus the implementation of measures, and consequently the improvement of ambient air quality. In 2019, as much as EUR 15.56 million more investments were paid out than in 2014. In the period from 2014 to 2019, most investments were in wood biomass boilers, followed by investments in heat pumps.

[PP09] Precipitation

17.02.2021

Trends in annual precipitation are not as obvious as temperature trends. Changes between years and regions are significant. According to the climate change projections, annual precipitation will slightly increase while changes in seasonal precipitation will be noticeable. The most worrying are summer conditions, because less precipitation and higher temperature might result in higher frequency of droughts. In winter, more precipitation may lead to an increase in flooding events.

[PP10] Extreme precipitation

17.02.2021

Precipitation is highly variable in space and time, even more than temperature (storms and hail). In the last two decades, Slovenia is observing catastrophic droughts and abundant precipitation resulting in floods, sometimes drought and floods occur even within the same year. The maximum snow cover depth and the depth of fresh snow decreased in the period 1961-2011

[ZD29] Population exposure to ozone

28.09.2022

In the period 2002-2021, the highest exposure to ozone concentrations were detected in the Primorska region in summer where air quality measuring stations in Koper and Nova Gorica detected highest ozone concentrations in ambient air. There are some differences from year to year in a level of ozone exposure due to meteorological conditions in the warm half of the year and other regional characteristics.
