The purpose of this study was to assess the application of several bioindication methods for the monitoring of environmental pollution from Pb and Cd. The study area centered on the town of Olkusz, Poland, which is one of the oldest centers for the metallurgical industry in Europe. The assessment of environmental pollution due to metals was performed using four frequently used bioindication methods: moss-bag (Sphagnum fallax), determination of metal accumulation in Pleurozium schreberi, silver birch foliage, and Scots pine needles. The region of Olkusz, and especially the area surrounding the mining and metallurgical Bolesław complex, was extremely contaminated with Pb and Cd. The results of the investigations are presented as contamination deposition maps. Despite the application of various methods and the resulting diversity of the specific exposure periods for different biomonitors, the spatial distribution of contamination shown on the maps was similar, as confirmed by the statistical analysis of the results.

    • "The use of a single monitor species is often common in local studies, but it becomes unusual when the scale of the research is regional or national and, thus, the difficulty of finding the aforementioned moss species at every sampling site increases (Galsomies et al., 2003). Many authors, being aware of this fact, have conducted research on both interspecies calibration and interspecies comparison with the purpose of (1) finding a calibration factor that allows for the use, simultaneous or interchangeable, of different moss species (Galsomies et al., 2003; Carballeira et al., 2008; Varela et al., 2013), and (2) testing new biomonitors that could yield the same conclusions as the ones validated in previous surveys (Coskun et al., 2009; Klos et al., 2011; Dmuchowski et al., 2011). Despite the attempts of these authors to define a standardized method to compare and to calibrate data when more than one moss species is included in a data set, nowadays there is not an accurate procedure for doing that.

    ABSTRACT: There is a significant lack of data in biomonitoring surveys from southern Europe and other Mediter-ranean biogeographic areas. This scarcity is mainly due to the impossibility of finding the commonlyrecommended species in a great portion of these dry environments. The present work was carried outwith the aim of assessing the validity of the moss Pleurochaete squarrosa (Brid.) Lindb. (PS) as a feasiblealternative in these regions. The study was developed in the Mediterranean area of Navarra, in northernSpain, where the response of PS to multiple atmospheric pollutants (N, Al, As, Cd, Cr, Cu, Fe, Hg, Mn, Ni,Pb, Sb, Ti and Zn) was compared to that of Hypnum cupressiforme Hedw. (HC), an accepted and widelyused species in biomonitoring surveys. Moreover, N isotopic signatures from both species were studiedto evaluate their effectiveness when identifying nitrogen emission sources. The enrichment factor (EF)approach was used to evaluate the heavy metal uptake, showing a similar behaviour for both species:low EF for Al, As, Cr and Fe; intermediate for Mn, Ni, Pb and Sb; and high for Cd, Cr, Hg and Zn. Equally,both species depicted the same N deposition patterns across the study area. However, regarding �15N,PS gave a more congruent picture with the location of the main sources of N emissions in the area. Thesedata suggest that PS may be a suitable biomonitor to fill the aforementioned gaps in Mediterraneanbiogeographic areas.

    • "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; Cos¸kun 2006). "

    ABSTRACT: The uptake of arsenic and other metals (iron, manganese, copper, zinc, lead, nickel and tungsten) by Pinus pinaster Aiton (the maritime pine tree) growing in soils and tailings around an abandoned mine (northern Portugal) was investigated. Aerial parts of Pinus pinaster trees were sampled from three substrate areas: a background area, in mine contaminated soils and in tailings. Vegetation material was separated into needles and stems and subdivided into tissues of different maturities (1-, 2-, 3- and 4-years-old). The sampling of the substrate in each area was also undertaken. In general, vegetation concentrations were strongly related to substrate concentrations. The results show that the contents of several elements depend as much on the plant organ as on the age of the tissue. For the researched elements, this species shows a great variability in behavior depending on the age of the organ. The data indicate that the older needles constitute the best samples for use in a conjunct biogeochemical analysis of these elements.
