Systematic research on soil pollution shows that soils in Slovenia, with some exceptions, are not heavily polluted. In 42% of top soil samples taken in the period from 1999 to 2019, no exceedances of the limit values of dangerous substances into the soil were detected. In 56% of the samples the limit values of inorganic pollutants were exceeded and in 5% the limit values of organic pollutants. The most polluted areas with inorganic pollutants were Jesenice, Idrija, the Celje Basin and the Upper Mežica Valley.

The value of agricultural output in Slovenia fluctuates in the period 1995–2020, which can be a consequence of fluctuation of changes in prices of agricultural products, changes in the volume of agricultural production or changes in both. In last couple of years, the key factor is the physical volume of production, which fluctuates markedly due to changing natural (weather) conditions. Similarly, the value of agricultural output, calculated per capita, fluctuates in the analyzed period, with long-term downward trend.

Air pollution is the most important environmental risk factor for human health, affecting an average of 400,000 premature deaths in the EU and costing Europeans an average of more than € 166 billion a year. In the case of the cities of Ljubljana and Maribor, external costs amount to almost EUR 271 million annually. Estimation of external costs of air pollution from transport is slightly decreasing.

Plans to improve air quality in Slovenia include a number of measures. It is crucial that the state ensures the financing of measures and thus the implementation of measures, and consequently the improvement of ambient air quality. In 2019, as much as EUR 15.56 million more investments were paid out than in 2014. In the period from 2014 to 2019, most investments were in wood biomass boilers, followed by investments in heat pumps.

The total renewable amount of groundwater in shallow aquifers in Slovenia in the hydrological year 2019 was below the average of the comparative hydrological water balance period 1981-2010.
