The quantity of end-of-life tyres collected for recovery increased dramatically when producer liability was introduced. Arround 16,000 tonnes of end-of-life tyres is produced, which is about 8kg per capita. In 2015, 65% of end-of-life-tyres have been recovered through material recovery and 35% through energy recovery.

Measurements of particle number concentration of ultrafine particles in ambient air in Ljubljana in period May 2012 -April 2014 is comparable to concentrations in other four European cities. Exposure to ultra-fine particles in the indoor air is roughly comparable or even slightly higher than exposure to ultra-fine particles in ambient air.

Population exposure to allergens has been increasing not only in Slovenia but also worldwide. This phenomenon is influenced by the increase in average air temperature. Higher average air temperature results in a longer growing season and thus the longer presence of allergenic pollen in the air. Particularly noteworthy is to mention the pollen of alder, birch, grasses and ambrosia. The severity of exposure to the allergen pollen of alder, birch, grasses and ambrosia shows large annual fluctuations, with distinct differences between the continental Slovenia and the littoral area.

Concentrations of sulphur dioxide in ambient air are no longer harmful for human health. Also, the critical annual value for the protection of vegetation is no longer exceeded. The improvement of the situation in the last decade is a result of the use of low-sulphur fuels in industry and the operation of desulphurisation facilities in thermal power plants.

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.
