AB  - Polycyclic aromatic hydrocarbons (PAHs) are among the most toxic compounds known
to man. Several PAHs are proven to be carcinogenic, mutagenic and teratogenic. Due to their wide
distribution in the environment and their toxicity, it is considered important to monitor the levels of
these compounds in foodstuff. PAHs have been detected in many foods including plant-based such
as vegetable oils, cereal grains, herbs, spices, teas and supplements. As the awareness for the
healthy lifestyle has increased globally, the intake of medicinal herbs as tea and spices has also
grown immensely. Therefore, even stronger emphasis must be made to monitor the toxic levels of
PAHs in herbs. The legislations of the maximum concentrations of certain contaminants in food of
the Republic of Serbia included PAHs values in dry herbs only by the end of 2019 (Official Gazette
RS, No. 81/2019) in comparison to European Commission Regulation dating from 2011. Therefore,
herein we focused on analytical method development for PAHs determination in medicinal herbs.

AB  - One of the most BTEX (benzene, toluene, ethyl benzene and a mixture of o-, m- and pxylenes) compounds are prominent environmental pollutants commonly found in discharges and
petroleum products. These volatile aromatic compounds (VOCs) are severely toxic to living
organisms if contact is maintained. They originate from incomplete combustion of organic matter,
and their major sources to the urban environment include vehicular emissions (mobile source),
gasoline evaporation, coal burning and residential heating, and waste incineration (stationary
sources). Water sediments are not well known as a source of BTEX. However, it is crucial to consider
that they can act as a source, as well as sink, of organic compounds, especially in a water body
located in an urban city exposed excessively to the above-mentioned sources of BTEX. In this study,
we aimed to identify and quantitatively analyze VOCs compounds in sediment by using purge-andtrap (P&T) gas Chromatography-Mass Spectrometry (GC-MS).

AB  - Urban lakes sediments unfortunately have received a large amount of
wastewater containing various contaminants such as heavy metals (HMs). Heavy
metals in urban lake sediments mainly originate from industrial discharge, heating
sources, traffic emissions and waste from municipal activities. The human health
and the whole ecosystems are threatened with potential harmful effects of following
metal pollutants As, Cd, Cr, Cu, Hg, Ni, Pb and Zn, due to their persistence, nondegradability, inherent toxicity, and bioaccumulation1. Therefore, the analysis of
lake sediments is a useful and important approach to characterize environmental pollution in aquatic ecosystems. Due to the diverse environmental conditions and
sources of HMs, different pollution indices are used to assess the anthropogenic
impact of PTEs in sediment samples2,3. In this study, ecological risk assessment of
the urban shallow lake sediments in Central Serbia by HMs was analyzed by
calculating single and multi- pollution indices and using multivariate techniques to
reveal the associated adverse effects of the investigated contaminants.
