Environmental indicators in Slovenia


Environmental indicators are based on graphs, maps and assessments and as such present environmental trends in Slovenia. The indicators represent one of the four pillars of our environmental reporting, and are prepared in accordance with the Environmental Protection Act. The Environmental Indicators in Slovenia website enables users to browse among 180 indicators. They are based on numerical data and they indicate the state, characteristics and trends of environmental development in Slovenia. They are prepared using a systematic approach based on data and monitoring, as shown in the information pyramid.

Good

In 2014, 21 out of 22 sections of surface waters met water quality limit values set for assessing the capability of water to support freshwater fish life.

Inapropriate water quality was detected in the cyprinid section of the Mura River between the road bridge in Petanjci and its confluence with the Ščavnica tributary (Mura Mota measurement site) due to excessive concentrations of ammonia, measured on 8 July 2014. The limit value for ammonia in cyprinid waters is 0.025 mg NH3/l, while the measured concentration was 0.043 mg NH3/l.

Neutral

Daily numbers of deaths increase during heat waves. Excess mortality during heat waves is greatest in the elderly and people with pre-existing illness. eight heat waves occurred in year 2019. The average number of deaths was 53 deaths per day during the period of heat waves and equal 53 deaths per day during the period of non-heat wave days. In 2019, no less or excess deaths than expected occurred during heat waves in total population.

Neutral

In Slovenia, emissions of persistent organic pollutants (polychlorinated biphenyl, polycyclic aromatic hydrocarbons, hexachlorobenzene, dioxins and furans) decreased between 1990-2019, primarily due to targeted legislation, improved control and use of best available technologies.

Neutral

In the last decades, major emissions of air pollutants from transport decreased. However, road transport remains one of the most significant sources of air pollution. In Slovenia in 2019 road transport contributed 44 % to the total emissions of nitrogen oxides. In the period 1990-2019 emissions of substances that cause acidification and emissions of ozone precursors in transport sector declined by 65 % and 72 %. In the period 2000-2019 emissions of particulate matter decreased by 44 %.

Neutral

The emission of primary particles, smaller than 10 µm (PM10), particles smaller than 2.5 µm (PM2.5) and all total suspended particles (TSP) have decreased in the period 2000 – 2019 in Slovenia by 25 %, 25 % and 26 %. The main source of emissions of particulate matter are households, mainly due to use of biomass for domestic heating.

Neutral

Heavy metal emissions in Slovenia significantly decreased between 1990 and 2019. This can be largely attributed to the implementation of the EU legislation, improved surveillance and use of the best available technologies.
