PLANTS AND MAXIMUM PERMISSIBLE CONCENTRATIONS OF HEAVY METALS IN SOIL
The tentative permissible concentrations and the maximum permissible concentration of heavy metals do not always give a complete adequate assessment of the effect on plants. Plant growth inhibition can be at concentrations below the maximum permissible concentrations and tentative permissible concentrations. We studied the effect of copper, zinc, c...

DEICING REAGENTS IN URBAN ECOSYSTEMS, USING THE EXAMPLE OF MOSCOW
Deicing reagents have an impact on the environment. The composition of the deicing reagents used in Moscow has undergone certain changes. However, the main components of deicing reagents were chlorides, including calcium chloride and (or) sodium chloride. We also conducted research on the effects of sodium chloride and calcium chloride on some urba...

RECYCLING OF WASTE SLUDGE FROM WWTP “GORIĆ” VALJEVO USING THE PROCESS OF STABILIZATION AND SOLIDIFICATION
The efficiency of wastewater treatment is not only measured by the quality of treated wastewater, but also by the efficiency of treatment and permanent disposal of sludge that is separated. In addition to harmless, the sludge also contains hazardous substances that are released from wastewater during treatment. This work aims to obtain a neutral an...

COLUMN SORPTION OF TOXIC IONS IN VARIOUS QUARTZ SAND - PACKED COLUMNS
In this study the adsorption of As(V), Cu(II) and Zn(II) ions from multi-species model solution was tested in dynamic conditions in sand columns containing a thin layer of bentonite (B), iron-based sludge (IS) and synthetic magnetic particles (MP). Adsorption experiments were performed in order to evaluate the removal efficiency and selectivity of ...

APPLICATION OF NEW TECHNOLOGIES IN THE WATER SUPPLY SYSTEM
Freshwater water resources are not inexhaustible [1]. In recent decades, more and more facts point to this statement from the European Charter for Water. Uncontrolled drinking water interventions, losses in water supply and climate change indicate the problem of sufficient quantities of drinking water [2]. Looking at this problem, it is hard to bel...

CRACK RESISTANCE OF REINFORCED CONCRETED AND REINFORCED RUBBER CONCRETE BEAMS
The issue of the appearance and development of cracks, as well as an increase the cracking moment is of particular importance for bending elements operating under aggressive environmental conditions. In structures without cracks, steel reinforcement operates in fairly favorable conditions. However, when cracks appear in the sections of the structur...
