Lyme borreliosis (LB) and tick-borne meningoencephalitis (TBE) are the most common vector-borne diseases transmitted by ticks. In Slovenia, from 3,000 to over 7,000 patients with LB were registered annually, and 133 TBE cases annually in the period from 2012 to 2021 (maximum in 2013 - 309 cases, the lowest number of cases was in 2015 and 2021 - 62 cases only). Living or working in the environments where there is a potential for infection is one of the most important factors for infection with LB and TBE.


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.
