The aim of the present work was to study exposure to PM in the indoor and outdoor microenvironment of a typical residence in the center of Athens. Simultaneous indoor and outdoor measurements of PM10 and PM2.5 were conducted, by the use of gravimetric and continuous samples, during October and...

Heterogeneous photocatalysis is an advanced oxidation process (AOP) which has been widely studied by numerous researchers in the world and is used to degrade or remove a wide range of pollutants in water and air. The photocatalytic oxidation and mineralization of phenol in aqueous catalyst...

In the present study, the wet oxidation of zinc and copper cyanide complexes (cyanide concentration of 1,000 mg dm-3) was conducted in a hydrothermal reactor, under oxygen atmosphere of which the pressure was set to 1 MPa. The pH of the reaction solution was kept in the range of 11 to 12 and the...

A field study on the impact of fireplace on the indoor air quality was carried out between 2004 and 2006, where two main contaminants, CO and particulate matters, were investigated in twenty seven randomly selected Irish houses. The results show that while the physical environment has been improved...

Agrochemicals, geochemical structure and industrial wastes create a potential source of heavy metal pollution in the aquatic environment. The porpuse of this study was to investigate the seasonal variations in five heavy metals (Cu, Zn, Cd, Pb and Cr) in the surface water of the Keritis river, one...

To achieve recycling of waste gypsum boards (CaSO4), production of calcium sulfide by reductive decomposition of CaSO4 was investigated and the decomposition product of CaS was used as a sulfuration agent in the treatment of nickel-containing simulated wastewater. At the end of the experiment...

A chemical vapour sensor working with a monochromatic light source and based on optical fibre coated with a thin siloxane polymer film has been developed for in situ monitoring of volatile organic compounds, such as ethylbenzene, xylene (o-xylene), heptane, octane, chloroform, carbon tetrachloride...

Two novel materials have been developed and tested in initial studies for the in-situ generation of sorption and reactive barriers for subsurface water treatment at low cost by introducing sorbents or reagents via injection wells. Both materials are based on finely-ground activated carbon with a...

Heterogeneous Catalysis and Electrocatalysis can be used very effectively on air pollution control. Air emissions coming either from mobile sources or from stationary sources, including volatile organic emissions, nitrogen oxides, hydrocarbons and carbon monoxide could be well converted to harmless...

The present paper aims at a treatment technique designed for special industrial wastewaters contaminated with only traces of halogenated organic compounds (HOCs) – concentrations which are nevertheless large enough to make a discharge into municipal sewage works impossible. Our research follows the...
