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.

In Slovenia, final users have at their disposal only around 73% of primary energy. In 2015 the rate reached its highest level. The efficiency of electricity and heat production is largely influenced by this share in far.

Asbestos (six natural minerals with fibrous) becomes dangerous when the material is worn, damaged, or by removing. Asbestos was widely used in construction and industry until 2003, when Slovenia banned its production. In Slovenia 163,455 tons of waste containing asbestos was generated in the period from 2005 to 2015. The majority (99.5%) presents construction materials. Most of waste containing asbestos derives from households (82%).

The highest levels of dioxins and PCBs were found in fish liver in EU between 1995 and 2010. Between 2012 and 2014 in Slovenia the highest levels were found in fish meat, following meat and fat tissues of cattle and sheep. Food producers and competent authorities should proactively make efforts to reduce dioxins and PCBs in feed and food.
