The incidence of malignant mesothelioma is (still) not decreasing in Slovenia or elsewhere in the world. Given the long latent period of the disease, it is likely to increase in Slovenia, especially among the elderly. Amon youngsters we expect to decline. We have not yet removed all asbestos products from the work and living environment, so the risk factor for this disease still exists, not only for workers who work professionally with asbestos products and waste, but also for others.

In Slovenia, 98.7% of surface water bodies are in good chemical condition. The two water bodies are in poor chemical condition due to the excess of metals. In general, Slovenian surface waters are not loaded with priority substances in the water, but they are loaded with too high concentrations of mercury and brominated diphenylethers in fish. These are ubiquitous pollutants that are excessively present in biota both in Slovenia and in Europe.

Water protection areas cover 3532 km² or 17,4% of Slovenia’s land surface in 2021. This is a slight increase, compared to 2017, but the goal of protecting the areas of all water sources for public water supply with a regulation on national level, has not been reached yet.

In Slovenia, nutrient overloading is still the basic problem concerning lakes and reservoirs, and from 2006 to 2019, no improvement is observed. In the assessment period 2016–2019, only 4 out of 11 lake water bodies were determined to be in good or very good trophic status. Overloading of lakes with phosphorus is usually a result of inadequate wastewater drainage and intensive agriculture in the watershed area.

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