As of 2022, the Potentially Contaminated Sites (PCS) inventory in Slovenia includes 671 sites that are a potential source of pollution due to past or present activities. With the establishment of the first database, Slovenia has taken the first of six steps toward systematic management and monitoring of contaminated sites. An analysis of the degree of environmental sensitivity and threat to human health due to potential contamination revealed that priority treatment is urgent for 35 sites and very urgent for 196 sites.

Foodborne diseases remain an important public health challenge and they are an important cause of morbidity and mortality worldwide. During 2018–2022 Slovenia reported 1152 different outbreaks. The most common were the respiratory disease outbreaks (902), outbreaks with contact transmission (186), followed by and foodborne disease outbreaks (22).

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 – 2021 in Slovenia by 21 %, 29 % and 20 %. The main source of emissions of particulate matter are households, mainly due to use of biomass for domestic heating.

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.
