Heavy metal pollutant in urban street dust has become a growing concern in recent years. Street dust samples from urban and suburban areas were collected from the Sarajevo area, Bosnia and Herzegovina, during the spring season of 2013. Samples were collected from low and high density traffic roads, industrial zones, parks, parking places, hospitals and local health centres, school gardens. The levels of heavy metals of street dusts were determined by flame atomic absorption spectrometry (FAAS). Cadmium, chromium, copper, nickel, iron, manganese, lead and zinc levels in the dust samples were found in the range of 0.58–3.65, 3.42–60.82, 5.49– 388, 9.31–161, 647–2244, 6.10–13.32, 31.63-1760 and 40.29–378 μg/g, respectively. The highest metal concentrations were found in samples from industrial zone and in the streets with heavy traffic. The lowest levels of the metal concentrations were found in the samples from health centres and school gardens. The concentrations of the metals were, in most of cases, similar to the mean world-wide contents of the street dust samples. Correlations between heavy trace metal levels of the dust samples were also evaluated.

Aims: This study explores the total quantity of sulfur secondary metabolites in the plant organs of garlic and ramsons, the content of total phenol and their correlation to the antioxidant capacity (AOC). There are different reports about correlation of secondary

In most cases, agents on the basis of chlorinated phenols were used for wood preservation. These substances penetrate deeper into the wood and because of their chemical stability it remain for decades. This is an environmental problem since chlorinated phenols are among the most acute and chronic toxic contaminants. One of the promising methods to resolve this problem is biodegradation of chlorinated phenols by microorganisms and by fungi, lately. The toxicity of chlorinated phenols against ligninolytic fungi Hypoxylon fragiforme (Hf) and Coniophora puteana (Cp) has been investigated in this paper. Results showed that the maximum concentration of chlorinated phenols, that allows the growth of Hp and Cp fungi, is 2.5 mmol/L. Testing the impact of eight chlorinated phenols on the growth of fungi, it was determined that chlorinated phenols show less antifungal activity to Hp fungus. Antifungal activity to both fungi increases with the number of substituted chlorine atoms. Also, an important role in antifungal activity, have a physico-chemical properties of chlorinated phenols, primarily LogKow, pKa and the Henry constant. Position of chlorine atoms in the molecule also has a certain influence.
