The average age of passenger cars in Slovenia increased from 6.8 years in 1992 to 10.6 years in 2021. The share of passenger cars by age has also changed – every decade from 2001 for around 50 %. On the other hand, the share of passenger cars aged less than three years is decreasing for around 30 % every decade. The shares of other types of vehicles showed more fluctuations during the last two decades and smaller changes in respective shares. However, there are now in general more vehicles older than 12 years and less vehicles aged less than three years.

Bad

In most aquifers in Slovenia, levels of plant protection products and their degradation products (metabolites) indicate a decreasing trend, which is mainly due to the decreased concentrations of atrazine and its metabolite desethylatrazine. The number of individual active substances and their degradation products exceeding the 0.1 µg/l threshold value for individual active substances is also decreasing.
