The level of air pollution with ozone has exceeded the target value for protecting human health in recent years at some urban background monitoring stations (Koper, Nova Gorica Grčna) and at the higher-altitude monitoring station Otlica. The long-term health protection goals have been exceeded at all monitoring stations. The warning value has also been exceeded in recent years only in the Primorska region and at higher altitudes, such as Otlica.

In 2022, 75% of energy supply in Slovenia was available to end-users, marking the highest level observed in the period. This percentage is largely influenced by the efficiency of electricity and heat production. In thermoelectric power plants and combined heat and power plants, almost half of the input energy was lost in 2022. Compared to the EU-27 countries, Slovenia ranked in the lower third. Electricity production from combined heat and power plants accounted for just over 6% of total production in Slovenia in 2021, with this share declining in recent years.

The average concentrations of dioxins and dl-PCBs in fish and seafood are the highest among all foods, followed by other animal-derived foods. Long-term average exposure of the Slovenian population to dioxins due to fish consumption does not exceed the Tolerable Weekly Intake (TWI), except for infants and toddlers, indicating a higher health risk for the most vulnerable groups. When considering only fish consumers, exposure to dioxins and PCBs exceeds the TWI in all age groups.

Lyme borreliosis (LB) and tick-borne encephalitis (TBE) are the most common vector-borne diseases transmitted by ticks. Between 2014 and 2023, Slovenia reported annually slightly less than 3,000 to over 7,000 cases of LB and an average of 105 TBE cases (the highest in 2020 - 187 cases, the lowest in 2015 and 2021 - 62 cases). Due to climate change, which influences the expansion of tick habitats and extends their activity season, the risk of infection may increase in the future. Increased awareness and individual prevention are key factors in reducing the burden of both diseases.

In Slovenia, in 2022, drinking water monitoring (quality monitoring) was conducted for 93.8% of the population at the point of use (user's tap) across drinking water supply systems or within 863 supply zones that served 50 or more inhabitants. This also included 26 smaller supply areas that provided water to public facilities and facilities involved in the production and distribution of foodstuffs.
