Groundwater is most polluted in aquifers with intergranular porosity in the northeastern part of Slovenia.

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.

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.

Foodborne diseases remain an important public health challenge and they are an important cause of morbidity and mortality worldwide. During 2014–2019 Slovenia reported 528 different outbreaks. The most common were the outbreaks with contact transmission where Norovirus was the most common identified agent (201 outbreaks), followed by respiratory disease outbreaks (147) and foodborne disease outbreaks (20). The multi-regional outbreak of monofasic S. Typhimurium was notified in 2019. The outbreak was not linked to any known sources.

In Europe 12.9 % infants die due to respiratory diseases. In 2018 and 2019 in Slovenia no newborns died due to respiratory diseases (NIJZ, 2020). Studies have shown a very complicated link between level of air pollution and infant mortality due to respiratory diseases, mainly due to various external factors (allergens, cigarette smoke, diet, lifestyle, etc.).
