Air pollution is the greatest environmental risk to health and a major cause of disease and premature deaths in Europe. Pollution due to PM_2.5 causes respiratory, cardiovascular, neurological and metabolic diseases. Since 2005, the number of premature deaths due to PM_2.5 pollution has been decreasing in Slovenia and in EU countries. In 2019, there were 1,409 premature deaths due to PM_2.5 pollution in Slovenia, and 307,000 in the European Union.

The Green Key is an international label for the environment, which is awarded to tourist accommodations and catering establishments that strive for environmental responsibility and sustainable behavior in the tourism industry. In Slovenia, 143 siteswere certified in 2022. In 2021, 3,165 sites were certified in the European Union, and 3,165 around the world.

Concentrations of lead in blood, urine and breast milk in Slovenia are relatively low and comparable to data cited in foreign literature. However, due to the proven neurotoxic effects of lead at concentrations lower than 50 µg/L of blood, there is currently no established safe exposure limit. In order to establish and maintain the lowest practically achievable burden of lead exposure for the population, it is reasonable to implement measures in addition to regular monitoring, targeting vulnerable groups such as children and women of reproductive age.

Concentrations of total arsenic in blood, urine and breast milk in Slovenia are low and comparable to concentrations worldwide.

Long-term surveillance will be possible once regular national human biomonitoring is established.

In the last decade (2012–2021), on average around 135,000 tons of hazardous waste was generated annually in Slovenia. This waste accounted for 1% to 3% of all generated waste in Slovenia. Since they contain substances harmful to the environment and health, they must be collected, recovered or disposed of separately from other waste.

In the last decade (2012–2021) each resident of Slovenia annually discards on average around 3.5 kg of hazardous municipal waste, of which the majority in waste electrical and electronic equipment (63%).
