“…This supports our conclusions based on PAH diagnostic ratios. Additionally, in agreement with our observations, biomass-burning emissions were found to be characteristic of the spring samples [39]. Specific markers of coal combustion were not detected in either of the studies.…”

“…Those data points closer to the cold-season cluster mainly correspond to spring samples, possibly indicating an influence of open biomass burning due to agricultural activities. Recently, positive matrix factorization (PMF) analysis has been applied to the same set of filter samples [39]. Six main sources of PM pollution were identified, including traffic emissions that were relatively constant throughout the year and the cold-season biomass-burning source, which was linked with individual heating devices.…”

“…Based on the obtained results, seasonal variation of thirteen PAHs and three NPAHs is presented for an urban environment in Central Europe. The measured concentrations were among others correlated with black carbon (BC) emissions that have been apportioned to traffic and biomass-burning sources in our recent work [ 39 ] to assess the contribution of distinct primary combustion sources to particulate PAHs and NPAHs in the atmosphere. We further combined those correlations with diagnostic ratios between specific PAHs and confirmed the attribution of major PM sources from our previous study [ 39 ].…”

Airborne particulate matter (PM) is a vector of many toxic pollutants, including polyaromatic hydrocarbons (PAHs) and their derivatives. Especially harmful is the fine fraction (PM2.5), which penetrates deep into the lungs during inhalation and causes various diseases. Amongst PM2.5 components with toxic potential are nitrated PAHs (NPAHs), knowledge of which is still rudimentary. Three of the measured NPAHs (1-nitropyrene (1-nP), 9-nitroanthracene (9-nA), and 6-nitrochrysene (6-nC)) were detected in ambient PM2.5 from Ljubljana, Slovenia, along with thirteen non-nitrated PAHs. The highest concentrations of pollutants, which are closely linked with incomplete combustion, were observed in the cold part of the year, whereas the concentrations of NPAHs were roughly an order of magnitude lower than those of PAHs throughout the year. Further on, we have evaluated the toxicity of four NPAHs, including 6-nitrobenzo[a]pyrene (6-nBaP), to the human kidney cell line, HEK293T. The most potent was 1-nP (IC50 = 28.7 µM), followed by the other three NPAHs, whose IC50 was above 400 or 800 µM. According to our cytotoxicity assessment, atmospheric 1-nP is the most harmful NPAH among the investigated ones. Despite low airborne concentrations of NPAHs in ambient air, they are generally considered harmful to human health. Therefore, systematic toxicological assessment of NPAHs at different trophic levels, starting with cytotoxicity testing, is necessary in order to accurately evaluate their threat and adopt appropriate abatement strategies.
