“…Airborne magnetite particles will be collected through deposition on the exposed outer 'A' bark of trees immediate to the PM source. This magnetite is then partially encapsulated into the inner bark ('B', 'C' and 'D' samples), probably as far in as the suber tissue, where it then undergoes reductive dissolution (Catinon et al 2008;Zhang et al 2008;Catinon et al 2009). Electron microprobe analyses support this hypothesis, showing that at least some of the magnetic particles are not just deposited on the bark external surface but are well integrated in it.…”

“…Sawidis et al 2011;Guéguen et al 2012). However, until now only a very limited number of studies have investigated the potential of measuring magnetic parameters of tree bark for monitoring air pollution (Flanders 1994;Kletetschka et al 2003;Zhang et al 2008;Kletetschka 2011). We are not aware of any previous biomonitoring studies conducted in this city, so we present the first results obtained through this approach for the selected study area.…”

“…Magnetometry is widely applied during the last decades as a fast, cheap and sensitive method for qualitative estimation of the degree of heavy metal, polycyclic aromatic hydrocarbons (PAH) and pesticides pollution of soils and sediments (Strzyszcz et al, 1996;Hay et al, 1997;Hanesch and Scholger, 2002;Chaparro et al, 2006;Jordanova et al, 2008;Kapiþka et al, 2008;Blundell et al, 2009). Vegetation, mainly needles and broad leaf trees is also studied, using one specific vegetation species in each study (Matzka and Maher, 1999;Hanesch et al, 2003;Moreno et al, 2003;Urbat et al, 2004;Gautam et al, 2005;Lehndorff et al, 2006;Davila et al, 2006;Zhang et al, 2008;Maher et al, 2008;Szonyi et al, 2008).

Detailed magnetic study on vegetation samples from several strongly polluted and clean sites inBulgaria is carried out in order to evaluate suitability of different species as passive dust collectors in magnetometry. From each location, available species among lichens, mosses, poplar leaves, dandelion, needles have been sampled. Magnetic susceptibility calculated on mass-specific basis shows wide variability between diamagnetic signal up to 846 u 10 8 m 3 /kg. Lichens and mosses are found to be the species, showing magnetic signals with the strongest contrast between clean and polluted environment. The main magnetic phase is magnetite-like according to the results from thermomagnetic analysis of susceptibility on magnetic extracts. Scanning electron microscopy (SEM) microphotographs reveal the presence of abundant particulate matter on vegetation surface both with anthropogenic (spherules) and lithogenic origin. Magnetic grain size deduced by the ratio of saturation remanent magnetization (SIRM) and mass-specific magnetic susceptibility (F) and coercivities (B c and B cr ) suggest that different species accumulate preferentially small SD-like grains from pollution emissions.Contrasting relationship of the ratio of anhysteretic remanent magnetization (ARM) and F for polluted vs clean sites deduced by needles and lichens may be related to transformation of the accumulated dust particles within lichens' tissue. This finding indicates that the exact species used as biological dust collector is of importance when studying spatial grain size distribution of magnetic dust particles. Pilot study on polycyclic aromatic hydrocarbons (PAH) content and its relation to magnetic parameters shows good correspondence between high levels of PAHs and high SIRM values for locations affected by non-ferrous industrial production.K e y w o r d s :

This study is a systematic analysis of the magnetic characteristics and heavy metal elements in soil samples collected from Lanzhou City, China. The 117 surface soil samples were measured to study the feasibility and effectiveness of environmental magnetism for evaluating heavy metal pollution in urban soils. Results of the study indicate that low-coercivity magnetite dominates the magnetic properties in the samples. The high values of the soil magnetic mineral concentration parameters and low values of magnetic particle size parameters are distributed throughout the northern area of Xigu District, the industrial zones of the eastern section of Chengguan District and the districts of the narrow sections connecting Chengguan District and the other three districts; these parameters are fundamentally consistent with the distribution of the high values of the Pollution Load Index and Nemerow Pollution Index. Semi-quantitative studies which use the environmental magnetic method to monitor pollution of heavy metals (such as As, Cr, Cu, Ni, Pb, Zn, and Fe) Chin Sci Bull, 2013, 58: 384395, doi: 10.1007 Anthropogenic activities, especially industrial processes, give rise to harmful emissions containing various magnetic minerals occurring in different amounts. These emissions are absorbed by the soil, sediments and plants through the atmosphere and runoff processes, and then change the circulation and existing conditions of the magnetic materials, therefore these special magnetic characteristics of the modern environment are all marked by human activities. The structure, type, concentration and particle size of these magnetic particles differ from those of the primary and secondary magnetic minerals occurring in the environment [1][2][3][4][5][6][7]. Moreover, magnetic particles are associated with elevated metal concentrations [8][9][10][11][12][13][14], especially Cu, Pb and Zn originating from paint, fuel additives, tyres and particulates from moving parts. Most researchers [15][16][17] consider that the heavy metals caused by combustion, such as copper, chromium, arsenic, zinc and lead, are always accompanied by iron oxide, and magnetic particles are strongly adsorbent and carriers of heavy metals, so the magnetic parameters may be an effective indicator of the content of certain pollutants. Environmental magnetism has become one of the main focuses of current research in pollution history reconstruction, monitoring the present environmental pollution, and tracing and separating the sources of pollution. The atmosphere [18][19][20][21], street dustfall [22][23][24][25], soil [1][2][3][4][5][6][7][8][9][10][11], sediment [12][13][14], leaves [26][27][28][29] and tree rings [30] are usually used as the research targets. Analysis is developed from a single Wang B, et al.
