Opis:: This paper constitutes the approach to correlate the results of gas purification properties performed with aid of photocatalysis with the cytotoxicity test results. The gas purification by means of photocatalysis is a subject well known a profusely described in literature. Easiness and continence of application causes the photocatalysis to be used in variety of industries, however this paper considers only automotive industry application. The effectiveness of photocatalysis have been proven experimentally by vast number of researchers. However, the literature contains only the information about the level of volatile organic compounds identification and reduction. The toxicity measure in terms of living cells was not yet fully tested and described in literature. Therefore, the standard chromatography test which enables quantitative identification of volatile organic compounds was confronted with a cytotoxicity tests revealing the virtual toxicity of gases before and after photocatalysis.

Opis:: Celem podjętego badania była analiza profilu związków lotnych czekolad naturalnych gorzkich i miazg kakaowych oraz określenie różnic między tymi profilami za pomocą techniki statystycznej PCA. Ekstrakcję związków lotnych materiału badawczego wykonano techniką HS-SPME, a następnie poddano analizie metodą chromatografii gazowej sprzężonej ze spektrometrią mas (GC/MS). Największe różnice w profilu związków lotnych wynikały z zawartości masy kakaowej w materiale badawczym. Ważną rolę w różnicowaniu czekolad odgrywała zawartość kwasu octowego oraz acetofenonu. Stwierdzono również, że w prawie wszystkich profilach frakcji lotnej pirazyny były obecne w zbliżonych ilościach i nie wpływały istotnie na przydzielanie próbek do grup. Tylko w czekoladach wysoko kakaowych (>70%) oraz miazgach wykryto estry kwasu octowego. Natomiast w przeciwieństwie do miazg, w czekoladach wysoko kakaowych wykryto wanilinę i etylowanilinę.
The main purpose of this study was profile analysis of volatile compounds of natural bitter chocolate and cocoa pulp and identify the differences between these profiles using the statistical technique of PCA. Therefore, a solid-phase microextraction of volatile fractions from headspace layer of research material was taken and then analyzed by gas chromatography coupled to mass spectrometry. The biggest differences in the profile of volatile compounds were resulted from the content of cocoa solids in the research material. Major role in differentiating played acetic acid and acetophenone content. It was also found that in almost all volatile fractions profiles pyrazines were present in similar quantities and they made no significant effect on the allocation of samples to groups. Only in high-cocoa chocolates (> 70%) and pulps were detected esters of acetic acid. However as opposed to the pulp, in high-cocoa chocolates vanillin and ethyl vanillin were detected.

Opis:: The paper presents a tentative solution to the problem of olfaction-based mobile robot navigation in the chemical plume. This type of navigation requires fast and reliable detection of small gradient of gas concentration in 3D space. The special sensor system designed to detect odour plume with significantly reduced inertia named ”chemical scanner” was proposed [5]. A special aƩention has been given to evaluate sensing system performance in stable and repeatable conditions. The ability to detect small gradient of gas concentration was examined on a special test bench. The real spatial distribution of tested gas in the air was estimated using CFD simulation. The results proved that the real-time detection of small (a few percent of measured value) difference in gas concentration on very short distance (a several centimetres range) is possible. The next stage of research will examine of the developed sensor system on the mobile plaƞorm for its navigation.

Opis:: This paper concerns the atmospheric-pressure microwave plasmas and their applications, mainly for gas processing. Several types of atmospheric-pressure microwave sources (MPSs), i.e. surface-wave-sustained MPS, nozzle-type MPSs, nozzleless MPSs, plasma-sheet MPSs and microwave microplasma sources - MmPSs (antenna- and coaxial-line- -based) as well as their performance are presented. The presented experimental results on the optimization of selected MPSs are confronted with results of the modelling of the electromagnetic field in them. The paper deals also with the applications of MPSs for the processing of gases. Two types of the plasma gas processing were experimentally tested: decomposition of volatile organic compounds (VOCs) and reforming of VOCs (mainly methane) into hydrogen. Results of the laboratory experiments on the plasma processing of several highly-concentrated (up to 100%) VOCs, including freon-type refrigerants, in the waveguide-supplied MPSs showed that the microwave discharge plasma is capable of fully decomposing the VOCs at relatively low energy cost. The use of waveguide-supplied coaxial-line-based and metal-cylinder-based nozzleless MPSs to methane reforming into hydrogen turned out to be energetically efficient. These selected results show MPSs to be an attractive tool for gas processing, including the harmful gas decomposition and production of useful gases.

Opis:: Constantly increasing amount of cars causes significant deterioration of air quality. Emission of harmful substances such as aromatic hydrocarbons or soot has negative influence for human health, especially for the respiratory system. Pollutants from engine vehicles are emitted at the people living height and, especially in cities, could cumulated because of weak ventilation among the street canyons made by buildings and infrastructure. Dynamic development of motorization and people lifestyle make the time spent inside the car is getting longer. Fumes and other air pollutants can get into the car cabin, what is extremely dangerous for driver and passengers. The pollutants inside the vehicle can also accumulate and if cabin is not well ventilated, the concentrations of them could be really high. It cause changing the microclimate inside the car cabin and has negative influence on the people staying inside the car, such as lowering of comfort and focus of driver and health effects. Previous studies have shown that the highest concentration of most of the pollutants in the vehicle cabin is located at the height of the driver's head. Of course, it depends on many factors like type (category) of vehicle or geometry of nozzles in the ventilation system. The study aim was to define concentration of volatile organic compounds in an E segment vehicle cabin by using computational fluid dynamic simulation.

Opis:: The inner atmosphere of a car vehicle became one of the most important environments of human life. Many elements inside of a car cabin are potential sources ofvolatile organic compounds (VOC's) which hazardous effect on human health is proved. To estimate quality of indoor air of a car the qualitative analysis of hydrocarbons is very important considering the fact that some substances (i.e. benzene, acetone and xylene isomers) despite low concentration level characterize toxic and carcinogenic properties. A significant impact on VOC's concentration has vehicle cabin eąuipment and quality of applied materials. The internal sources of the pollution are elements of cabin equipment (textiles, foams, plastic materials), solvents in glues, paints, lacąuers and car cosmetics. The external sources of the pollution are pollutants emitted to environment in gas phase by mobile or static sources. This paper presents the results of the research which aim was qualitative and quantitative analysis of VOC's concentration inside of various classes of car vehicle cabins. The research was done in Emission Research Laboratory of the Division of Motor vehicles and Internal Combustion Engines. The analysis was done according to European standard (EN ISO 16017-1: 2006) on gas chromatograph (Varian 450 GC) eąuipped in capillary column and flame-ionization detector (FID). Keywords: Volatile hydrocarbons, indoor measurements, car vehicle cabin.

Opis:: Styrax is a gorgeous species combined with high medicinal and ornamental values, however, in- formation about its floral scents is limited. This study aimed to reveal the floral scent compounds and the dynamic changes in the flowering process of Styrax japonicus, S. grandiflora and S. calvescens. Static headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry was adopted in the pres- ent study. The results showed that 24, 22 and 22 volatile compounds were present at three flowering stages, among which linalool, ocimene, α-pinene and germacrene D dominated in different species. Terpenes were the main floral scent compounds in all species, whereas there was considerable relative content of ketones in S. japonicus. Among the major terpenes, α-pinene, ocimene and myrcene were the common volatiles in these species, while β-elemene and allo-ocimene were the specific volatiles in S. japonicus and S. calvescens, respec- tively. The highest content of terpenes occurred at initial flowering stage in three species. The differences in the type and content of principal compounds contributed to the fragrance diversity among these species. A solid foundation for understanding the complexity of volatile emission could be obtained from our findings, meanwhile, effective utilization of abundant terpenes in flowers of Styrax species should be applied.

Opis:: The use of zeolites as sorbents has been investigated as a replacement for existing costly methods of removing organic contaminants from water solutions. Zeolites can be modified by inorganic salts, organic surfactants, metals or metal oxides in order to increase their adsorption capacity. The unique ion exchange and adsorption properties of zeolites make them very suitable for application in the removal of organic compounds such as volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), phenols and other complex petrochemicals. Many different studies have demonstrated their effectiveness in reducing the concentrations of organic contaminants as well as petroleum derivatives in water, which has been summarized in this paper.

Opis:: This study aims to identify the lignicolous basidiomycetes species that synthetize volatile organic compounds with potential applications in food industry, cosmetics, perfumery and agriculture. We have collected fruiting bodies from different woody plants and the lignicolous basidiomyctes species were identified by their macroscopic and microscopic characteristics. From the context of the fresh fruiting bodies small fragments of dikaryotic mycelium were extracted and inoculated on PDA and MEA media for isolation and pure cultures are kept in dark at a temperature of 25°C. 11 species of lignicolous basidiomycetes, belonging to 6 families and 5 orders were isolated in pure culture. The isolates were analyzed in vitro and the main characteristics that were observed are: the general aspect of the surface and the reverse of the colonies, the changing in colour and the growth rate of the mycelium and also the specific odour which indicates the presence of the organic volatile compounds. for the first time lignicolous fungi like Flavodon flavus (Klotz.) Ryv., Ganoderma lucidum(Curtis) P. Karst, Hexagonia apiaria (Pers.) Fr., Lenzites betulina (L.) Fr. Lenzites eximia Berk. & M.A. Curtis, Lenzites sterioides (Fr.) Ryv., Navisporus floccosus (Bres.) Ryv., Phellinus gilvus (Schwein.) Pat., and Trametes pini (Thore) Britzelm. were producing characteristic smell that indicates presence of Volatile organic compounds. For the first time from Gujarat, India the Volatile organic compound producing fungi were identified and their culture characters also described.
