TL;DR: The seasonal changes in ambient mass concentrations and chemical composition of fine particulate matter (PM2.5) were investigated in three locations in Poland and it was found that the greatest hazard from PM2.3-related carbonaceous matter occurs in Katowice, southern Poland, in winter, when very high concentrations of PM 2.5 are maintained by poor natural ventilation in cities, weather conditions, and the highest level of industrialization in Poland.

TL;DR: Concentrations of all studied metals associated with PM10 increased at the roadside compared to the background about ten times (one order) while metals contained in PM2.5 showed two to three times elevated concentrations (except Fe—five times and Cr—no increase).

TL;DR: The carried out study indicates the necessity of reducing PAH emission from solid fuel combustion, which is reflected in PM2.5-bound PAHs concentrations and their diagnostic ratios.

TL;DR: Forty-nine components of ambient particulate matter (PM) in size-fractionated PM were investigated at an urban background site in Katowice in the non-heating season of 2012, finding that PM0.6 posed the greatest health hazard from the mixture of the 16 PAHs that it contained, PM1.6–40 was the next, and thehazard from thePM0.03–0.26-bound 16PAHs was the smallest.

TL;DR: The chemical composition of the two dust fractions and the element enrichment coefficients in the two seasons, referred to proper emission profiles, proved about 80% of PM2.5–10 mass coming from anthropogenic sources, mainly from fuel combustion and specific municipal emission shaping the winter emission of ambient dust in the area.
