[ZR05] Air pollution by sulphur dioxide

Good
12.01.2018

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.

[ZR06] Air pollution by nitrogen dioxide

Good
12.01.2018

The measured concentrations of nitrogen dioxide and total nitrogen oxides in outdoor air do not exceed the prescribed limit values, so these two pollutants are not harmful human health and vegetation.

[ZR07] Air pollution by ozone

Bad
12.01.2018

In recent years, the level of air pollution with ozone has been above the target value in most locations, including rural areas and higher altitudes, while (due to less sunny and cooler summers) the action value has been exceeded only in the Primorska region and in some places at higher altitudes. The highest ozone concentrations have been recorded in the Primorska region due to weather patterns that are favourable for ozone formation and the transport of ozone and its precursors from northern Italy.

[ZR08] Air pollution by particulate matter

Neutral
28.09.2018

In 2017 air pollution due to PM10 was comparable to years before. Exceedences of the daily limit PM10 concentration were above the allowed annual number of 35 in year 2017 at ten measuring sites in the interior of Slovenia: four in urban-traffic type of measuring site, three in urban background, two in rural-agricultural type and one in suburban background. All exceedances were recorded in the cold half of the year because individual heating is the major source of PM10 and the unfavourable meteorological conditions are present.

[ZR09] Emissions of substances that cause acidification and eutrophication

Good
21.08.2018

In Slovenia, total emissions of the pollutants that contribute to acidification and eutrophication have decreased by 78 % between 1990 and 2016. Emissions of SOx have decreased by 97 %, NOx by 48 % and NH3 by 17 %. The emissions of sulphur oxides, nitrogen oxides and ammonia were in 2016 below the prescribed target values.

[ZR10] Emissions of ozone precursors

Good
26.07.2017

In the period 1990–2015, emissions of total ozone precursors decreased by 54%. Emissions of nitrogen oxides decreased by 48%, carbon monoxide by 66%, non-methane volatile organic compounds by 55% and methane by 18%. The decrease is mainly a consequence of 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.

[ZR12] Emissions of heavy metals

Neutral
27.07.2017

Heavy metal emissions in Slovenia significantly decreased between 1990 and 2014. This can be largely attributed to the implementation of the EU legislation, improved surveillance and use of the best available technologies.

[ZR13] Persistent organic pollutants emissions

Neutral
27.07.2017

Emissions of persistent organic pollutants in Slovenia in the period 1990-2015 decreased primarily due to a combination of targeted legislation, improved control and use of best available technologies.

[ZR14] Air emission projections

Neutral
28.11.2018

Projections show a reduction in SO2, NOx, VOC, NH3 and PM 2.5 emissions by 2030, mainly due to more strict legislation and implementing a number of sectoral policy measures. Reduction is too slow for NOx in the light of the 2020 targets, with respect to the targets for 2030 for all pollutants except for NH3.
