Effect of soil pollution with PAHs on the amount of maize biomass and accumulation of cadmium and lead
AbstractKrakow is a city where, due to mostly so-called low-stack emissions and intensified traffic, air dustiness continues to increase and often, especially in winter, the threshold values of dustiness are exceeded. Air dustiness increases the number of airborne microorganisms, as they are associated with particles of dust to form bioaerosols. Actinomycetes are one of the most significant components of bioaerosol. Their presence in bioaerosol is dangerous to human health, since even very low concentrations of these microorganisms can cause allergic reactions. The aim of this study was to verify the relationship between the concentration of actinomycetes in the air of Krakow depending on spatial variation of thermal conditions and the degree of air dustiness. The study was conducted using a cascade impactor for bioaerosol particle separation, including the respirable fraction. Moreover, the measurements of air dustiness were performed simultaneously, separating 4 dust fractions. The research was conducted over 12 months (full calendar year) and the measurements were performed once per month, within one day, at 16 research sites. The lowest average numbers of actinomycetes were recorded in places characterized by little urban green space (eg Main Square or crossroads). On the other hand, the highest numbers were found in green areas (eg Blonia Park meadows, green area at the Krakow University of Technology). Based on the normative classification of air quality (Polish Standard PN-89/Z-04111/02) the number of actinomycetes in 75 % measurements showed that the air was polluted, including heavily polluted air in 16 % measurements. The most common actinomycetes belonged to the genus Streptomyces (St. albus, St. badius, St. globisporus).
