This study aimed to evaluate the suitability of two bioaerosol generation systems(dry and wet generation) for the aerosolization of microorganisms isolated from the International Space Station, and to calibrate the produced bioaerosols to fulfill the requirements of computational fluid dynamics model(CFD) validation. Concentration, stability, size distribution, agglomeration of generated bioaerosol and deposition of bioaerosols were analyzed. In addition, the dispersion of non-viable particles in the air was studied.Experiments proved that wet generation from microbial suspensions could be used for the production of well-calibrated and stabile bioaerosols for model validation. For the simulation of the natural release of fungal spores, a dry generation method should be used. This study showed that the used CFD model simulated the spread of non-viable particles fairly well. The mathematical deposition model by Lai and Nazaroff could be used to estimate the deposition velocities of bioaerosols on surfaces, although it somewhat underestimated the measured deposition velocities. 相似文献

The communities of xylotrophic fungi were studied in the northern and middle taiga subzones of western Siberia, in forests growing in the region of oil and gas production and exposed to various anthropogenic factors (emissions of petroleum gas flares, oil pollution, spills of mineralized oil-field water, etc.). Structural and functional rearrangements in these communities were revealed, and the prevalence of rot in the tree stand was assessed. 相似文献

The effect of boric acid on the ability of herbaceous plants to absorb heavy metals has been studied. The results show that
at a low content of boron in sandy loam soil (0.0007 mg/kg dry matter), boric acid at doses of 0.1–3.0 kg/ha stimulates the
accumulation of certain heavy metals in the aboveground part of plants from the families Asteraceae (Taraxacum officinale Wigg.), Poaceae (Phleum pratense L.), and Fabaceae (Trifolium pratense L.). The most active accumulation is characteristic of dandelion (T. officinale) plants, which allows this species to be considered promising for phytoremediation of soils with a low boron content given
that boron is applied at specified doses. 相似文献
