“…Magnetic properties of tree leaves as biocarriers of the deposited atmospheric dust have been investigated in relation to air pollution by many authors (Hofman et al, 2017;Jordanova et al, 2010b;Jordanova et al, 2003;Kardel et al, 2018;Kardel et al, 2011;Kardel et al, 2012;Maher et al, 2008;Matzka and Maher, 1999;Mitchell and Maher, 2009;Mitchell et al, 2010;Moreno et al, 2003;Rodriguez-Germade et al, 2014;Sagnotti et al, 2009;Zhang et al, 2006). There are also numerous studies on magnetic properties of tree needles (Jordanova et al, 2010;Lehndorff et al, 2006;Urbat et al, 2004), tree barks, rings or branches (Brignole et al, 2018;Chaparro et al, 2020;Vezzola et al, 2017;Wuyts et al, 2018;Zhang et al, 2009;Zhang et al, 2008), lichens, in situ or transplanted (Chaparro et al, 2013;Kodnik et al, 2017;Marie et al, 2016;Marie et al, 2018;Paoli et al, 2017;Salo et al, 2012;Winkler et al, 2019Winkler et al, , 2020, and moss and transplanted moss bags (Fabian et al, 2011;Limo et al, 2018;Salo et al, 2012Salo et al, , 2016aSalo et al, , 2016bMakinen, 2014, 2019;Vukovic et al, 2015a;…”
