AB  - Heavy metals are naturally occurring elements, but they are regarded as significant environmental pollutants due to their high density and high toxicity even at low concentrations. The aim of this paper is the evaluation of the pollution level of heavy metals in the river and riverbank sediments, as well as the estimation of their origin and spatial differences along the course of the Vrbas River through Banja Luka. The concentrations of metals have been assessed using the Inductively coupled plasma – optical emission spectrometry and Advanced mercury analyzer for mercury determination. The anthropogenic impact on heavy metal concentration in sediments was estimated by the calculating of pollution indices: geoaccumulation index (Igeo ), contamination factor (Cf ), pollution load index (PLI) and potential ecological risk index (Er). Obtained results indicate that there is no statistically significant spatial difference in metal concentration, indicating that heavy metals in sediments have a constant source. The anthropogenic impact expressed by the values of pollution indices showed that sites are generally uncontaminated by Co, Cr and V and moderately contaminated by Zn, Cu and Ni. On the contrary, lead, mercury and cadmium pose the highest ecological risk. The anthropogenic source of Pb, Hg and Cd is industry, municipal waste and the combustion of fossil fuels. The obtained results demonstrate the high ecological risk and the need for environmental monitoring, with the aim to support an efficient strategy to reduce local pollution and contamination of the investigated system.
AB  - Тешки метали су елементи природног порекла, али се сматрају значајним полутантима животне средине због велике густине и токсичности, чак и при малим концентрацијама. Циљ овог рада је процена нивоа загађености речних и приобалних седимената тешким металима, као и процена њиховог порекла и просторне расподеле дуж тока реке Врбас кроз Бањалуку. Концентрације тешких метала одређиване су помоћу индуктивно спрегнуте плазме – оптичке емисионе спектрометрије и наменског живиног анализатора. Антропогени утицај на концентрацију тешких метала у седиментима процењен је израчунавањем различитих индекса загађења: индекса геоакумулације (Igeo),фактора контаминације (Cf), индекса оптерећења загађењем (PLI) и индекса потенцијалног еколошког ризика (Er). Добијени резултати указују да не постоје статистички значајне просторне разлике у концентрацији метала, што указује на то да тешки метали у испитиваним седиментима имају константан извор. Антропогени утицај изражен у вредностима индекса загађења показао је да су локације генерално незагађене кобалтом, хромом и ванадијумом, а умерено загађене цинком, бакром и никлом. С друге стране, кадмијум, жива и олово представљају највећи еколошки ризик. Антропогени извори ових метала су индустрија, комунални отпад и сагоревање фосилних горива. Добијени резултати показују висок еколошки ризик и потребу за мониторингом животне средине, подржавајући развој ефикасне стратегије за смањење локалног загађења и загађења испитиваног подручја.

AB  - PAHs are a group of ubiquitous persistent organic pollutants that cause sever global environmental 
concerns for ecosystems and human health due to their potential toxicity and carcinogenicity. PAHs are a group of organic pollutants strongly related to anthropogenic activities such as settlement, transport, and industrial development. Due to their lipophilicity and persistence, PAHs are readily adsorbed in the particulate matter once they enter the urban river system and are finally deposited in the sediment. [1] The aim of this work was to evaluate the distribution of PAHs in the sediments of Vrbas River, to assess their occurrence and to establish the origin 
 (pyrogenic/petrogenic) of pollution sources.This study focussed on investigation on the state of pollution and identification of potential sources of contamination of river sediments by polycyclic aromatic hydrocarbons along entire course of the Vrbas River (Bosnia and Herzegovina). 
Nineteen sampling points were selected covering the entire course of the Vrbas River (Bosnia and 
Herzegovina). The samples were extracted in a Soxhlet apparatus and fractionated using column 
chromatography. In the fraction of aromatic hydrocarbons, PAHs were analysed by gas chromatography - mass spectrometry (GC-MS) in a selected ion monitoring (SIM) mode. The ions 
monitored were: m/z = 128 (naphthalene), m/z = 152 (acenaphthylene), m/z = 154 acenaphthene), 
m/z = 166 (fluorene), m/z = 178 (phenanthrene andanthracene), m/z = 202 (fluoranthene and 
pyrene), m/z = 228 (benzo[a]anthracene and chrysene), m/z = 252 (benzo[b]fluoranthene, 
benzo[k]fluoranthene, benzo[j]fluoranthene, benzo[e]pyrene and benzo[a]pyrene), m/z = 276 
(indeno[1,2,3-c,d]pyrene and benzo[g,h,i]perylene), and m/z = 278 (dibenzo[a,h]anthracene) [2]. Thereafter numerous PAH diagnostic ratios were calculated and analysed. High molecular weight polycyclic aromatic hydrocarbons (4, 5 or 6 rings) are more prevalent in the observed samples. The analysis of different PAH diagnostic ratios indicate the pyrogenic PAHs origin. In most samples, according to calculated parameters, these are combustion products of coal, grass, and wood, while in some samples these parameters implicate the fuel combustion origin of PAHs. No regularity was observed in the distribution of PAHs in the samples, indicating the existence of multiple sources of these compounds in the investigated area. Thus, the conclusion is that 
this area was exposed to both point and diffuse sources of PAH contaminants.

AB  - The Vrbas River is an important river ecosystem in Bosnia and Herzegovina with a length of 250 km and catchment areas of 5900 km2 . Before reaching Banja Luka, the Vrbas River passes through a canyon and numerous gorges, which are from 1955 protected by the Law on the Protection of Natural Values. This river flows through many towns and villages along the entire course, but the main anthropogenic influence comes from Banja Luka, one of the largest cities in Bosnia and Herzegovina.The aim of this research was to characterise extractable organic matter of sediments from the Vrbas River in the city area of Banja Luka. Six samples were collected at locations which were selected based on the vicinity of potential sources of anthropogenic pollution: 1 and 3 – sites near bridge and frequent traffic, 2 – city’s promenade, 6 – site in the vicinity of the thermal power plant, 7 – site close to Banja Luka Brewery and the bridge on frequent road, and 8 – site close to the food industry “Vitaminka”. Extractable organic matter was isolated with dichloromethane/ methanol mixture using a Soxhlet apparatus. Hydrocarbons were isolated from the extracts using a column chromatography and analyzed by gas chromatography – mass spectrometry (GC-MS). Detailed analysis of n-alkanes (m/z 71), diterpanes (m/z 123), hopanes (m/z 191) and steranes (m/z 217) was done. The individual peaks were identified by comparison with literature data [1] and based on their mass spectra (library: NIST11). Among saturated hydrocarbons diterpane, 16α(H)phyllocladane is the most dominant component in almost all samples (Fig.1). The exception is a sample 7. This diterpane is followed by n-alkanes with a predominance of higher odd homologues.  It indicates predominately native organic matter of Vrbas river sediments, originated mostly from terrestrial plants. That was noticed the predominant presence of native organic material in noticed in samples 2, 3, 6, while the presence of oil type pollutants was confirmed in other samples (1, 7, 8), which are near the bridge and frequent traffic roads. Fig 1. Total ion current (TIC) of saturated fraction. The previous study regarding the contents distribution of heavy metals in these sediments showed that most contaminated samples are at sampling points 2 and 6 [2]. That is not the case with oil contamination pointing to probably different sources of anthropogenic pollution.
