The paper deals with the design of quantitative evaluation resulting from the decomposition products of surface-treated wood in the combustion process. This proposal evaluation in addition to monitoring the quality characteristics of the surfactant treated wood will add information on fire protection and selected environmental characteristics (emission of volatile organic compounds).

An emissions barrier was used in premises with indoor air complaints due to emissions from the buildings in question. The emissions comprised chlorophenols/chloroanisoles and polycyclic aromatic hydrocarbons (PAH) from treated wood, and volatile organic compounds (VOC), mainly 2-ethylhexanol, from PVC flooring and the glue used to paste the flooring onto a concrete slab. Attaching the barrier at the surfaces from where the emissions were spread (floor, walls, ceiling) resulted in a fresh and odour-free indoor air. We conclude that using an emissions barrier in buildings made unhealthy by moisture is an efficient way of restoring a pleasant and healthy indoor air.

Abstract A new type of emissions barrier was used in premises with indoor air complaints due to emissions from the buildings in question. The emissions comprised chlorophenols/chloroanisoles and polycyclic aromatic hydrocarbons (PAH) from treated wood, and volatile organic compounds (VOC), mainly 2-ethylhexanol, from PVC flooring and the glue used to paste the flooring onto a concrete slab. Attaching the barrier at the surfaces from where the emissions were spread (floor, walls, ceiling) resulted in a fresh and odour-free indoor air. We conclude that using an emissions barrier in buildings made unhealthy by moisture is an efficient way of restoring a pleasant and healthy indoor air.

This paper refers to the study of biofuel as an alternative power source for turbine aviation engines. Blends of Jet A-1 fuel and synthesized hydrocarbons from Hydrotreated Esters and Fatty Acids (HEFA) technology at different proportions, such as 25%, 50% and 75%, were used for tests. All the test results were compared with the neat Jet A-1 fuel. A miniature GTM series turbojet engine was used in the test rig studies. During the tests conducted at a specific rotational speed, selected engine operating parameters as well as the emission of volatile organic compounds were measured. In terms of engine performance, no significant differences were found between the test fuels. The results of volatile organic compound emissions indicate that among the most toxic compounds the highest concentrations were obtained for benzene. The addition of the HEFA synthetic component and increasing its proportion in the blend resulted in the obtained concentration values for benzene showing a decreasing trend. The plotted utility profile indicates that the most optimal blend, i.e., the least toxic, is the blend with the share (v/v) of 62.5% of Jet A-1 fuel and 37.5% of HEFA component.

Chemical vapour deposition (CVD) is an important technique that uses volatile precursors to produce thin film deposits on an exposed substrate, having the capability to generate different types of nanostructures (e.g. nanoparticles, nanotubes, nanofibers or nanocomposites) as catalytic materials. The environmental hazard of volatile organic compounds (VOCs) requires efficient methods to reduce their emission into the atmosphere, due to their high potential to cause severe health issues, along with their extended spread in the environment. Catalytic combustion proves to be one of the most effective means for the abatement of VOCs, employing different catalysts, such as noble metals or non-noble metal oxides, to facilitate the oxidation process of the pollutants. These catalysts can be prepared through various methods as multiple steps wet processes or CVD techniques, indicating the superiority of the CVD-prepared catalysts compared to those prepared using the former type of process, due to the ability to achieve high dispersion of the active material, together with enhanced textural and morphological properties. This paper aims to present the various CVD techniques employed in the fabrication of different catalysts with the possibility of generating materials at nano-scale for use in numerous reactions, mostly in combustion process for VOCs decomposition.
