Biomagnetic monitoring of atmospheric pollution is a growing application in the field of environmental magnetism. Particulate matter (PM) in atmospheric pollution contains readily measurable concentrations of magnetic minerals. Biological surfaces, exposed to atmospheric pollution, accumulate magnetic particles over time, providing a record of location-specific, time-integrated air quality information. This review summarizes current knowledge of biological material ("sensors") used for biomagnetic monitoring purposes. Our work addresses the following: the range of magnetic properties reported for lichens, mosses, leaves, bark, trunk wood, insects, crustaceans, mammal and human tissues; their associations with atmospheric pollutant species (PM, NO, trace elements, PAHs); the pros and cons of biomagnetic monitoring of atmospheric pollution; current challenges for large-scale implementation of biomagnetic monitoring; and future perspectives. A summary table is presented, with the aim of aiding researchers and policy makers in selecting the most suitable biological sensor for their intended biomagnetic monitoring purpose.

“…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;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), 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;Vukovic et al, 2015b).

Background: Environmental magnetism, focusing on ferrimagnetic iron oxides, provides useful additional information on pollution of different environments. Magnetic methods have been applied to studies of atmospheric dust, namely PM10 (particulate matter smaller than 10 micrometers) in, e.g., industrial or urban areas. Until now, positive correlation was reported between concentration of iron oxides (expressed in terms of either magnetic susceptibility, saturation remanent or saturation induced magnetization) and concentration of PM10 or smaller. Purpose of this study was to verify the relationship between iron oxides and PM at monitoring site close to source of emissions rich in iron oxides during period of smoggy conditions. Results: We examined 24-hours PM10 and PM1 samples, collected during 10 days of smoggy winter period at a site close to steel plant, which represents a significant source of atmospheric emissions in industrial region of Northern Moravia (Czech Republic), known for generally high degree of air pollution. Magnetic hysteresis loops were measured in order to obtain parameters reflecting the concentration and grain-size distribution of iron oxides. Our data show unexpected negative correlation between saturation magnetization (concentration of ferrimagnetic iron oxides) and both PM1 and PM10 concentrations, to the best of our knowledge the trend not being reported yet. Conclusions: Our finding may seemingly disqualify magnetic methods as useful proxy in air pollution studies. However, we suggest that this is an exceptional case, specific to this region and monitoring site, as well as to synoptic conditions during the smoggy period. Although the significant dust emissions are presumably rich in iron oxides, the overall air quality at the monitoring site is determined by the general environment, controlled by many other sources of different character in the region, and by the specific climatic conditions. Thus, the nearby steel plant, presumably emitting dust rich in ferrimagnetic iron oxides, dominates the deposited dust at the nearby monitoring site only during very few days of suitable weather (namely wind speed and direction).

“…A number of authors [20, 22-24, 33, 34] have used the techniques of environmental magnetism and biomonitoring along with complementary techniques (SEM and chemical analyses) to characterize spatial variations in anthropogenic pollution using different species of lichen. In previous studies in Tandil (Argentina), magnetic biomonitoring was carried out using lichens and methodologies identified as: (1) native species collection [20,21] and (2) in situ magnetic susceptibility (κ is ) measurements or "in situ magnetic biomonitoring" [22], respectively. The first methodology used native lichen species living on tree bark in the study area that were collected and measured in the laboratory.…”

Lichens are able to retain airborne pollution-derived particles in their thalli for a long time, and therefore, their use in assessing atmospheric pollution may be suitable and beneficial. In this study, we transplanted species of Parmotrema pilosum in bags and exposed them to atmospheric pollutants at different sites over the course of 1 year. The exposed lichen retained anthropogenic ferrimagnetic Fe oxides that were identified and characterized by environmental magnetism methods, X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The ubiquitous magnetite, released by metallurgical factories and vehicular sources, had small grain sizes (< 0.1-1 μm) falling in the range of harmful particulate matter PM 2.5 and PM 1.0. According to the anhysteretic ratios (χ ARM /χ, ARM/SIRM), magnetic grain size tends to increase (ratios decrease) over time. Concentration-dependent magnetic parameters evidenced the cumulative presence of anthropogenic magnetite-like particles which reached high values during the study period, increasing from an initial mass-specific magnetic susceptibility χ value (mean ± S.D.) of 24.1 ± 5.0 × 10 −8 m 3 kg −1 to higher values up to 51.2 ± 23.0 × 10 −8 m 3 kg −1. Joint analysis of meteorological data and magnetic susceptibility indicated a magnetic enhancement (χ/χ initial) during the austral winter season when mean temperatures were lower; moreover, relative decreases in χ values after rainy periods are observed. This simple and low-cost methodology allowed us to study, in controlled exposure periods of 1-11 months, the ability of transplanted lichens to retain fine and ultrafine airborne particles that may have impacts on human health.
