Salvia officinalis L. (Dalmatian sage) is used traditionally in medicine as herbal tea and as a tonic, antiseptic and for inflammations and infections in the mouth. Also, sage is widely used as food flavouring, either as dried leaves or as the essential oil or oleoresin. Thus, any heavy metal accumulation by this plant would increase the possibility of heavy metal toxicity to consumers. In Montenegro, sage and some other aromatic herbs grow wild in close proximity to major roads. This study aims to establish the impact of pollution on the composition of sage leaves and this first investigation acts as a platform from which further work will follow. The total contents of Pb, Cd, Cu and Zn in Salvia officinalis leaves and in essential oil, solvent extract, tea brew and tea infusion at selected distances from a heavy metal pollution source was examined. Generally, it was found that the concentration of heavy metals decreases at 50 m, i.e. 100 m from the edge of a major road. Therefore the impact of road traffic through the pollution of aromatic herbs was noted. The concentration of hazardous heavy metals Pb and Cd in all investigated sage extracts was bellow detection limits of the analytical technique used while the solubility of heavy metals Zn and Cu was the highest in tea infusion extract.

Phenological traits, yield, and fruit characteristics of 14 plum cultivars of late maturation period were studied in the region of Belgrade in the five-year period (2013–2017). The control cultivar for comparison was ‘Stanley’. The average time of flowering was in the first half of April, and of fruit maturation in the second half of August and the beginning of September. Yield per tree was lowest in the cultivar ‘Pozna Plava’ (10.2 kg) and highest in the cultivar ‘Topking’ (23.6 kg). Compared to the control, significantly lower yield was achieved in three cultivars: ‘Pozna Plava’, ‘Vengerka Pozdnyaya’, and ‘Narach’. Fruit weight ranged from 26.1 g in the cultivar ‘Elena’ to 57.0 g in the cultivar ‘Empress’. Compared to the control, it was significantly higher in three cultivars (‘Empress’, ‘Vengerka Pozdnyaya’, and ‘Tophit’). All studied cultivars had high soluble solids content, ranging from 17.1% to 21.6%. The best rated cultivar for fruit appearance was ‘Empress’, while cultivars ‘Nada’ and ‘Pozna Plava’ were best scored for taste.
