The estimated average long-term dietary intake of metals (lead, cadmium, and mercury) for the adult population of Slovenia does not exceed the corresponding reference points (BMDL) or health-based guidance values (tolerable daily/weekly intakes). However, for children, the average intake of lead, cadmium and mercury (fish consumers) may be exceeded, a situation similar to that in the EU.

In Slovenia, in 2024, 29% of children (0-14 years old) in larger cities were exposed to concentrations of 0-20 µg PM₁₀/m³ and 71 % of children (0-14 years) in larger cities were exposed to concentrations of 20-30 µg PM₁₀/m³. In Europe, most children live in an environment where PM₁₀ concentrations are below 26 µg/m³.

Precipitation is highly variable in space and time, even more than temperature, and extreme precipitation events (storms with torrential rain, hail) and drought are of particular concern. In the last two decades, Slovenia  has been observing extreme droughts and abundant precipitation resulting in floods. Drought and floods can occur even within the same year. The maximum snow cover depth and the depth of fresh snow decreased in the period 1950–2022.

Temperature observations show increasing trend of maximum and minimum absolute temperature in between 1961 and 2022, reflecting a global warming. Number of hot days is increasing, including the frequency of extreme hot days with daily maximum temperature above 35 °C. In the summer of 2013, the highest temperature so far was measured in Slovenia, and local temperature records were observed at many meteorological stations. A record number of hot days was observed in 2022. Number of days with temperature below zero show a decline.

In 2023, around 182 million pieces of plastic carrier bags were placed on the Slovenian market, of which 99% were those with a wall thickness of less than 50 microns (light plastic carrier bags). In Slovenia, the consumption of lightweight plastic carrier bags amounted to 85 bags per capita in 2023 In the same year, 145.9 million pieces of single-use food containers made wholly or partly of plastic and 174.4 million pieces of single-use beverage cups made wholly or partly of plastic were placed on the Slovenian market.
