Heavy metals are one of the group of toxic pollutants in the soil. Over the past years, many researches have been conducted on the migration of heavy metals in soils and various models were developed in order to study the ...

Vertical Speed Control Measures are vertical elevated segments of roadway that require a vehicle to slow. Typical vertical speed control measures include speed humps, speed tables, raised sidewalks and raised intersections. ...

Due to high specific surface area, well-developed porous structure and surface functionality biochar has a potential for being used as low-cost adsorbent for adsorption of organic and inorganic contaminants from aqueous ...

With the number of vehicles increasing, the analysis of urban air pollution becomes expedient. This article deals with the integrated evaluation of road transport realised pollutant impact on the urban air. During research, ...

Wooden railway sleepers are impregnated with the chemicals that prevent the disassembling of the wood splitter. Such chemical wood impregnator as creosote or shale oil have been widely used to prolong the lifetime of wooden ...

Research studies on the adsorption kinetics are conducted in order to determine the absorption time of heavy metals on coffee grounds from liquid. The models of adsorption kinetics and adsorption diffusion are based on ...

The main objective of the surface water monitoring – periodically to conduct water quality testing, to find out the possible sources of pollution in time and to warn population. Water samples for analysis of surface water ...

Biogas is a fuel, which can be produced from a renewable energy source – biomass. Such a gas can be freely used in small farms or food industry to produce heat or electricity. Two main components of biogas – metahne CH4 ...

World Health Organization (WHO) defined health as being “a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity”. Physical factors (noise, vibration, electromagnetic ...

Air cleaning from VOC (volatile organic compunds) group of contaminants could be done by using different types of methods: adsoption, absorption, chemical or thermal oxidation. However, the most promising method is bio ...
