Introduction. To perform mass studies of the indoors air environment of the ammonium content the actual issues are the shortening of the sampling time and material costs for their implementation, reduction of adverse effects of ammonium with keeping of the objectivity of results. Aim. The elaboration of the method of short-term air sampling for indoors ammonium and comparative assessment ofdifferent methods of sampling in the course of modeling and field tests. Materials and Methods. Air sampling for ammonium was carried out according to the developed program and standard method, under the average daily 4-fold taking according to State Standards (GOST) 17.2.3.01-86 andRD 52.04.186-89. The evaluation of the significance of deviations of analysis results was carried out in accordance with GOST R ISO 5725-6-2002 and Recommendations of the Interstate Standardization RMG - 61-2003. Results. There were executed model and field tests of air sampling for ammonium according to the standard method and the program of short-term sampling. There were obtained significantly comparable results of ammonium content in the indoor air in the course of model and field tests. Conclusions. Sampling according to the developed program has a number of advantages, including: the shortening of sampling time, material costs, increasing in productivity in the analysis of indoor airfor the ammonium content. The execution oftest sampling according to the developed program allows to reduce the time of ammonium exposure to personnel carrying out the test sampling.

The aim of the first port of this study was to select the optimal technique for the enumeration and identification of viable mould propagules in the indoor air of houses. A comparison was made between the results obtained with six commercially available air sampling devices in combination with four culture media. The optimal technique was defined as the technique with the best precision and the highest yield. The coefficients of variation were high (generally > 20%) for all combinations. Statistical analysis showed that the Slit sampler and the N6-Andersen sampler in combination with DG18 and MEA gave the best precision and the highest yield in terms of CFU/m3 and number of species isolated. In the second part of this study the presence of viable mould propagules in the indoor air of 46 houses in relation to the dampness of these houses was investigated, using the N6-Andersen sampler in combination with DG18. To assess the variability in time, the measurements were repeated after five weeks. Overall, between the two periods no difference was found between the average number of CFU/m3 in the investigated homes. However, the variation between homes was much smaller than the variation within homes. The mean number of CFU/m3 was somewhat higher in “damp” houses than in “dry” houses. However, this difference was not significant. Furthermore, there were no demonstrable differences in the presence of specific mould species in “damp” and “dry” houses.

Unknown Composition

Introduction. Lack of studies proving or denying passive smoker health risks caused by electronic cigarettes prevented from introducing restrictive measures and considering them to be tobacco products as early as in 2013. Indoor air pollution by consumed nicotine-containing products in extra-low concentrations which could be detected using high-tech lab mass-spectrometry techniques was the object of study. Material and methods. “Unknown composition” air sampling was carried out in the process of simulation tests. Three types of tobacco products were used in the tests: tobacco cigarettes, electronic nicotine-delivery system (ENDS), battery-powered heat-not-burn tobacco cigarettes (IQOS) with tobacco sticks. “Unknown composition” air samples were analyzed for volatile organic compounds, medium volatile organic compounds, polycyclic aromatic hydrocarbons (total and separately 16 priority PAHs, inorganic elements (Si, Pb, Cu, Cr, Ni). Sampling was carried out three times a day on separate days for each type of product and control, a total of 12 “unknown composition” air samples being collected. The study of “unknown composition” air samples was carried out at the accredited chemical-analytical center “Arbitrazh” of the D.I. Mendeleev Institute of Metrology (accreditation certificate РОСС RU.0001.510650).Results. A total number of 115 chemicals were determined, and among them, substances significant concentrations of which are most likely related to tobacco or nicotine consumption, as compared to control, and depend on the type of nicotine-containing product, were identified. Statistically significant concentration excess (р≤ 0.05), as compared to control, was seen for 27 chemicals in indoor air polluted by-products of consumed tobacco cigarettes; when using electronic nicotine-delivery system (ENDS) the excess (р≤ 0.05) was shown for 2 chemicals, i.e.: acenaphthylene and benz(a)perene, and when using heat-not-burn tobacco products (IQOS) the excess of studied chemical concentrations in comparison with control was not reported.Conclusion. Findings of comparative analysis of “unknown composition” air sampling give evidence that a much larger number of harmful chemicals at significantly exceeded concentrations (р≤ 0.05), including those causing human health risks, is released when smoking cigarettes, as compared to using ENDS or IQOS.
