Accumulation of polycyclic aromatic hydrocarbons and heavy metals in the tree foliage of Eucalyptus rostrata, Pinus radiata and Populus hybridus in the vicinity of a large aluminium smelter in Argentina

PAHs accumulation on leaves of six evergreen urban shrubs: A field experiment

“…For example, the range of BbF concentrations in the leaves of our species was 1.47e33 mg kg À1 DW vs. 3.7e42.5 mg kg À1 DW in Lodovici et al (1998); BkF concentrations in our case were 2.53e22 mg kg À1 DW vs. 0.5e13.3 in Lodovici et al (1998). Our data are not far from those recently reported by Rodriguez et al (2010Rodriguez et al ( , 2012, although their work is referred to different species (T. capillaris and Lolium multiflorum).…”

“…In leaves of L. nobilis collected in smaller towns Lodovici et al (1998) recorded 0.2e13.1 mg kg À1 DW of BaP. Rodriguez et al (2012) in the vicinity of a large aluminum production plant recorded 2.34e705, 0.25e38.2 and As explained, the purpose of our work was not to study the dynamics of the 16 PAHs but rather to study the differences in their accumulation by the species, to select the more suitable one for environmental biomonitoring. The selected species are frequently used for urban landscaping and to grow green barriers to diminish the pollutant impact in specific sites, i.e.…”

“…In the first, pre-existing plants growing in urban and periurban areas, along roadsides, public parks or private gardens were sampled (Lodovici et al, 1998(Lodovici et al, , 2003Howsam et al, 2000;Lehndorff and Schwark, 2004;Singh and Verma, 2007;Wang et al, 2008;Lehndorff and Schwark, 2009;De Nicola et al, 2011b;Papa et al, 2012;Noth et al, 2013;Terzaghi et al, 2013). In the second scenario, the plants were sampled in the surroundings of disused or still working industrial sites (Sharma and Tripathi, 2009;Rodriguez et al, 2010Rodriguez et al, , 2012Wang et al, 2012). So, in both cases plants were exposed to air pollution for a long time, whereas we studied PAHs accumulation in evergreen shrubs transplanted to the experimental sites a couple of months before starting the sampling.…”

Temporal variation in the arsenic and metal accumulation in the maritime pine tree grown on contaminated soils

“…During the last two decades, there has been an increase in the study of tree leaves as bioaccumulators of trace elements in the vicinity of industrial plants (e.g., Dmuchowski et al 2011;Oliva and Mingorance 2006;Rodriguez et al 2012) and in urban environments (e.g., Baycu et al 2006;Guéguen et al 2012;Kord et al 2010;Liu et al 2007;Sawidis et al 2011). In addition, although not as numerous, there have also been studies of tree leaves as bioaccumulators in rural and background areas (e.g., Chiarenzelli et al 2001;Coşkun 2006).…”

The occurrence and source evaluation of polycyclic aromatic hydrocarbons in urban atmosphere using moss as biomonitor and GC-MS analysis

“…The most harmful PAHs are generated during the incomplete combustion of organic material, predominantly due to anthropogenic activities [3]. In highly populated and heavily urbanized or industrialized areas, the most significant emission sources are residential heating, coal gasification, asphalt production, and motor vehicle exhaust [4].…”
