“…Decreased levels of rev/m 3 were detected mainly in the rainy months (December 2010 to February 2011 -period II). Rain cleanses some particles from the atmosphere, but this does not mean that there is no further risk of exposure to contaminants associated with the particles that remain in the environment [2,41,42].…”

Respirable particles (PM2.5) can become associated with organic matter containing several compounds such as polycyclic aromatic hydrocarbons (PAHs). Many PAHs have been identified as cancer-inducing chemicals. The mutagenicity of airborne particles is generally associated with PAHs, but recent reviews show that PAHs may not be the predominant mutagens in atmospheric pollution, and that nitroaromatic compounds, aromatic amines and aromatic ketones, often found in moderately polar or highly polar organic fractions, are potent mutagens. Nitro-polycyclicaromatics (nitro-PAHs) are persistent environmental mutagens and can be found in airborne suspended particles from direct sources such as diesel and gasoline exhausts, or may be products of atmospheric reactions in the presence of NO 2 and NO 3 radicals. In the present work we compared PAH levels and mutagenicity using gas chromatography spectrometry and the Salmonella/microsome assay on organic extracts of PM2.5 for Salmonella typhimurium strain TA98. The samples were collected in two periods: (I) July to October 2010 and (II) November 2010 to May 2011 at three sites in Rio de Janeiro -(1) low urban traffic at the University campus; (2) heavy . Mutagenic frameshift responses in the absence of metabolic activation were detected at all the sites in periods I and II. In the presence of metabolic activation this response was observed for all three sites in period I, but only for site 3 in period II. Nitroarenes and dinitroarenes were detected at all three sites in period I. In period II, the presence of nitroarenes was also detected at all sites, but dinitroarenes were only detected at sites 2 and 3. The information generated in this study shows that different levels of PAHs and nitroderivatives, influenced by seasonal variations in climatic conditions, probably contribute to the detected airborne mutagenicity.

“…[Klumpp et al, 2009] or Taraxacum officinale Weber [Kleckerová and Dočekalová, 2014]). In addition to trace elements, the efficacy of trees for biomonitoring cesium radionuclides (Cosma et al, 2016), platinum‐group metals (Bonanno and Pavone, 2015), and polycyclic aromatic hydrocarbons (PAHs) (Rinaldi et al, 2012) has been proven. EuroBionet, a European network for the assessment of urban air quality, has developed standard methods to monitor trace elements and PAHs using ryegrass ( Lolium multiflorum ) and curly kale ( Brassica oleracea L. var.…”

This study evaluates the results of the characterization of air pollution in urban green areas using edible plants. To this purpose, we examined the effect of location (i.e., three different levels of pollution), substrate (peat moss and vermiculite), and plant species (oilseed rape [Brassica napus L.] and kale [Brassica oleracea L.]) on the accumulation of trace elements on leaves. A total of 36 samples of unwashed leaves were digested with HNO 3 -H 2 O 2 and analyzed for 27 elements by inductively coupled plasma mass spectrometry. Considering the location, plants exposed next to the road showed higher contents of traffic-related elements, and additionally, outdoors samples were enriched in marine aerosol ions. Cadmium and Pb concentrations did not exceed the European legal maximum levels for vegetables, so their consumption would be safe for human health. Results support the hypothesis that edible plants such as kale and rapeseed could be used as bioindicators of atmospheric pollution.
