In Slovenia, in 2020, children (0-14 years old) in larger cities were exposed to concentrations of 21-30 µg PM₁₀/m³. In Europe, most children live in an environment where PM₁₀ concentrations are below 26 µg/m³. It is a worrying fact that in Slovenia in 2018 about 2% of children were exposed to concentrations between 31 and 40 PM₁₀/m³, and in 2019 as much as 53%, fortunately, concentrations decreased in 2020, so children were not exposed to concentrations above 30 µg PM10 / m3 that year.

In 2019, 93% of the Slovenian population used drinking water from the drinking water supply systems. This includes 858 supply zones with regular monitoring of drinking water quality at the user tap. In 2019, regular monitoring of the drinking water did not include 7% of the Slovenian population. This is because regular monitoring is not obliged for the supply systems with less than 50 people (own drinking water supply, self-sufficiency). Generally, all residents of Slovenia living in cities used regulary monitored drinking water.

In recent years, cadmium and lead concentrations in the kidneys and livers of roe deer has decreased below the level of toxic concentrations that could have a direct adverse effect on the health of the individuals of this species. Nevertheless, cadmium concentrations in the internal organs of roe deer exceed the admissible concentration determined by law in many areas of Slovenia (taking into consideration the suitability for human consumption).

Higher levels of heavy metals and nitrogen are observed around the urbanized areas, industrial regions and around thermal power plants. The reason for elevated levels at the western part of Slovenia is transboundary transport of air pollutants from the Po Valley in Italy, however at the eastern part might be transit traffic and agricultural activity. A decrease of heavy metals and nitrogen in mosses is observed in Slovenia since 1995.
