Concentrations of sulphur dioxide in ambient air are no longer harmful for human health. Also, the critical annual value for the protection of vegetation is no longer exceeded. The improvement of the situation in the last decade is a result of the use of low-sulphur fuels in industry and the operation of desulphurisation facilities in thermal power plants.

Concentrations of nitrogen dioxide and total nitrogen oxides in ambient air do not exceed the prescribed limit values. Consequently, they are not harmful for human health and vegetation.

In recent years, ambient concentrations of ozone in urban and suburban areas has been above target value for human health protection. Long-term targets have been exceeded at almost all measuring sites. Due to fewer hot sunny summer seasons, the information threshold levels have been exceeded only in the Primorska region and in some places at higher altitudes - Otlica. However, also some exceedances have been recorded at measuring sites that are not directly exposed to traffic.

Air pollution with PM10 was the lowest in 2021 since we have been carrying out measurements. For the first time, at no monitoring site did the sum of exceeding the daily limit value for PM10 (50 µg/m3) exceed the number of 35, which is allowed for the whole year. Even the annual limit value for PM10 in 2021 was not exceeded at any monitoring site.

In Slovenia, total emissions of the pollutants that contribute to acidification and eutrophication have decreased by 81 % between 1990 and 2021. Emissions of SOx have decreased by 98 %, NOx by 66 % and NH3 by 22 %. The emissions of sulphur oxides, nitrogen oxides and ammonia were in 2021 below the prescribed target values. Slovenia also met its emission reduction commitments compared to the year 2005.

Emissions of total ozone precursors in Slovenia decreased by 62 % in the period 1990 to 2021. Emissions of nitrogen oxides decreased by 66 %, carbon monoxide by 70 %, non-methane volatile organic compounds by 54 % and methane by 26 %. The reason is mainly the introduction of more stringent emission standards for motor vehicles. This measure contributed to a significant reduction in emissions of nitrogen oxides and carbon dioxide from road transport which is the main source of ozone precursors.

Heavy metal emissions in Slovenia significantly decreased between 1990 and 2020. This can be largely attributed to the implementation of the EU legislation, improved surveillance and use of the best available technology.

In Slovenia, emissions of persistent organic pollutants (polychlorinated biphenyl, polycyclic aromatic hydrocarbons, hexachlorobenzene, dioxins and furans) decreased between 1990-2021, primarily due to targeted legislation, improved control and use of best available technologies.

Projections show a reduction in SO2, NOx, NMVOC, NH3 and PM 2.5 emissions by 2030, mainly due to more strict legislation and implementing a number of sectoral policy measures. Reduction is inline with set targets for 2020 and 2030. For PM2.5, NMVOC and SO2 emissions in 2030 are only slightly lower than according to targets, so there is a possibility that targets will not be met. To avoid that, it is of great importance that trends are regularly monitored and if necessary additional measures are prepared.
