AB  - Introduction and study objectives: Lindane is a generic name for γ-hexachlorocyclohexane, one of the isomers from the group of Hexachlorocyclohexanes (HCH) [1]. Due to its neurotoxic activity, it had a very wide application, from agricultural to non-agricultural purposes. As a result of its lipophility, lindane can easily pass through the blood-brain barrier. The reason of his neurotoxicity is that it can interact with GABAA receptors and obstruct GABA neurotransmitter signaling in nervous system. People who have been exposed to lindane for a long time can experience serious health problems, such as: poor liver function, cardiac arrhythmias, and irregular menstruation. Due to its adverse health effect, lindane is classified as a “pregnancy category C” chemical [2]. It is also one of the Persistent Organic Pollutants (POPs) that were listed under the Annex A (elimination) of the Stockholm Convention with a specific exemption for use as a human health pharmaceutical [3]. The aim of this paper was the assessment of the immobilized titanium dioxide photocalytic properties in lindane degradation. Methodology: Spray pyrolysis method was used for a synthesis of thin titanium oxide films on the foils of the stainless steel [4]. The lindane solution was incubated with TiO2 and exposed to UV/VIS light. Aliquots were taken from the reaction mixture after 0, 2, 4, 6, 8, 10 and 12 hours. Lindane was extracted according to the EPA method 505 [5], and analyzed using an Agilent 7890A gas chromatograph (GC) connected to an electron capture detector (ECD). The GC was equipped with a Thermo Scientific™ TraceGOLD™ TG-5MT capillary column (60 m × 0.25 mm ID × 0.25 μm). The temperature program used for gas chromatography was: Initial heating temperature: 50 °C for 3 minutes, then heating at a rate of 30 °C/min to 210 °C for 20 minutes. Hydrogen with a flow rate of 60 mL/min was used as the carrier gas. Results and conclusions: Photoactivity of immobilized titanium dioxide in the degradation of lindane was measured as a percentage of lindane’s degradation compared to its initial concentration. The obtained results demonstrated that after two hours 45.32 % of lindane was degraded, while after twelve hours the percentage of degradation increased to 98.20 %. In this study we proved that the immobilized titanium dioxide can be used as a productive and fast photocatalyst for lindane photodegradation.

AB  - Environmental pollution with petroleum and petrochemical products has attracted much attention in recent years. The present study is focused on the investigation of urban soil pollution in the area of thermal plant New Belgrade with more than 200000 residents. Thermal Power Plant New Belgrade is located on the left bank of the Sava, about 1 km from the Sava’s confluence with the Danube. The Thermal Power Plant complex consists of storage tanks for crude oil and oil products and it was contaminated due to break-down of the mazut reservoirs (2009, during a gas crisis) and NATO bombing of the reservoirs (1999). A total of 45 soil samples were collected in May, 2015, and in total 8 geochemical parameters were determined by using official or recommended methods [1]. Statistical data processing includes application of multivariate statistical methods to previously systematized data on geochemical parameters in soil samples from Belgrade city. Two multivariate statistical methods have been applied – hierarchical cluster analysis (HCA) and factor analysis – analysis of the main components (PCA). From the output of the hierarchical cluster analysis, a total of three clusters of the soil samples were recognized according to the level of clustering. Cluster A and B are linked at a shorter distance and are together linked to Cluster C at a longer distance. Component 1 of the PCA dominated in group A. Samples of group A contained the maximum amounts of total aliphatic hydrocarbon (TPH) (71.85±17.9), and Unresolved/Resolved complex mixture (U/R) (3.02±1.8) higher than the other groups. The results of the soil analyses indicated that most samples classified as C1 may reflect anthropogenic contamination of the urban environment. The results showed that the top soil contained high concentration of TPH (90.65 mg kg−1). This may be a result was caused by crude oil spills and leaks which continuously occured for long periods of time. According to the “Regulation on the program of systematic monitoring of land quality, indicators for According to the “Regulation on the program of systematic monitoring of land quality, indicators for assessment of the risk of land degradation and the methodology for making remediation programs “(Official Gazette of RS, No. 88/2010-Annex 13) are not higher than” values that may indicate significant contamination “-remediation values, but are higher than ”limit values“, which means that this area must be programs “(Official Gazette of RS, No. 88/2010-Annex 13)) are not higher than” values that may indicate significant contamination “-remediation values, but are higher than” limit values “, which means that this area must be under permanently monitoring.

The distribution of Pr/n-C17, and Ph/n-C18 ratios for almost all samples are small than 1, indicate biogenic contribution, except of some samples are around 1, points to petroleum contamination source in urban area of Belgrade city.
