A practical and long-term usable air-cleaner based on the synergy of photocatalysis and plasma treatments has been developed. A field test of the air-cleaner was carried out in an office smoking room. The results were compared to previously reported laboratory test results. Even after a treatment of 12,000 cigarettes-worth of tobacco smoke, the air-cleaner maintained high-level air-purification...

Thirty five Slovak households were selected for an investigation of indoor environmental quality. Measuring of indoor air physical and chemical factors and a questionnaire survey was performed during May 2017. The range of permissible operative temperature was not met in 11% of objects. Relative humidity met the legislative requirements in all monitored homes. Concentrations of total volatile o...

Hydrocarbons emissions were measured from an aeration tank of a municipal wastewater treatment pilot plant. The collected off-gas samples were characterised for C2–C7 hydrocarbons using GC-FID analytical technique while the total volatile organic compounds (TVOC) were measured using a continuous hydrocarbon gas analyser. Approximately, the estimated emission rates for 1 m3 of wastewater from th...

Infants spend most of their time sleeping and are likely to be exposed to elevated concentrations of chemicals released from their crib mattresses. Small-scale chamber experiments were conducted to determine the area-specific emission rates (SERs) of volatile organic compounds (VOCs) in a collection of twenty new and used crib mattresses. All mattress samples were found to emit VOCs and the mea...

Atmospheric emissions from a pilot wastewater treatment plant performing aerobic and anoxic processes were investigated. The experiment was performed by sealing the whole aeration tank with an airtight cover of polyethylene in order to obtain a de"ned #ow rate of the o!-gas. By measuring concentrations in the known #ux of the o!-gas emission rates were determined. Due to the dimensions of the p...

Translation validation (TV) is the process of proving that the execution of a translator has generated an output that is a correct translation of the input. When applied to optimizing compilers, TV is used to prove that the generated target code is a correct translation of the source program being compiled. This is in contrast to verifying a compiler, i.e. ensuring that the compiler will genera...

Interior decoration with man-made board is a kind of common porous material, which is solid skeleton and the fluid inside the complex mixture. The establishment of the interior decoration of multiphase multidimensional model of mass transfer of volatile organic compounds released by artificial board, and based on the geometrical characteristic of wood-based panel thickness is thin, the artifici...

Sydney Metro is the biggest project of Australia’s public transport, which was designed to provide passengers with more trains and faster services. This first implemented in 2017 planned be completed 2024. As presented, currently construction stage located on ground stations Trains Bankstown line (T3). Based this stage, several activities will generate air pollutants, affect quality around area...
