“…Metals in peat pore waters were not measured as a part of this study. We recognize that metals can have significant impacts on the fluorescence properties of natural organic matter, but solid peat is almost entirely organic matter with low levels of metals (mg kg −1 ) that are normally enriched from natural backgrounds by atmospheric transport . Furthermore, metals contents in peat pore waters are in the ng L −1 range , several orders of magnitude lower than DOC levels observed here (Table ).…”

In this study, we contrast the fluorescent properties of dissolved organic matter (DOM) in fens and bogs in a Northern Minnesota peatland using excitation emission matrix fluorescence spectroscopy with parallel factor analysis (EEM-PARAFAC). EEM-PARAFAC identified four humic-like components and one protein-like component and the dynamics of each were evaluated based on their distribution with depth as well as across sites differing in hydrology and major biological species. The PARAFAC-EEM experiments were supported by dissolved organic carbon measurements (DOC), optical spectroscopy (UV-Vis), and compositional characterization by ultrahigh resolution Fourier transform ion cyclotron resonance mass spectroscopy (FT-ICR MS). The FT-ICR MS data indicate that metabolism in peatlands reduces the molecular weights of individual components of DOM, and oxygen-rich less aromatic molecules are selectively biodegraded. Our data suggest that different hydrologic and biological conditions within the larger peat ecosystem drive molecular changes in DOM, resulting in distinctly different chemical compositions and unique fluorescent fingerprints. PARAFAC modeling of EEM data coupled with ultrahigh resolution FT-ICR MS has the potential to provide significant molecular-based information on DOM composition that will support efforts to better understand the composition, sources, and diagenetic status of DOM from different terrestrial and aquatic systems.

“…Filzmoser et al 2009b), the multivariate analysis is almost never computed using appropriate transformations, specifically designed for compositional data. Meyer et al (2015) recently proposed a method based on the scores of the compositional biplot, computed after a simple clr -transformation of the original variables. In our case, PC1 has a strong positive multiplicative contribution to the log-ratios of metals originating from mining activities (Ni, Cr, Co)/Ti.…”

The aim of this study is to explore the use of lichens as biomonitors of the impact of nickel mining and ore treatment on the atmosphere in the New Caledonian archipelago (South Pacific Ocean); both activities emitting also Co, Cr and possibly Fe. Metal contents were analysed in thirty-four epiphytic lichens, collected in the vicinity of the potential sources, and in places free from known historical mining. The highest Ni, Co, and Cr concentrations were, as expected, observed in lichens collected near ore deposits or treatment areas. The elemental composition in the lichens was explored by multivariate analysis, after appropriately transforming the variables (i.e. using compositional data analysis). The sample score of the first principal component (PC1) makes the largest (positive) multiplicative contribution to the log-ratios of metals originating from mining activities (Ni, Cr, Co) divided by Ti. The PC1 scores are used here as a surrogate of pollution levels related to mining and metallurgical activity. They can be viewed as synthetic indicators mapped to provide valuable information for the management and protection of ecosystems or, as a first step, to select locations where air filtration units could be installed, in the future, for air quality monitoring. However, as this approach drastically simplifies the problem, supplying a broadly efficient picture but little detail, recognizing the different sources of contamination may be difficult, more particularly when their chemical differences are subtle. It conveys only relative information: about ratios, not levels, and is therefore recommended as a preliminary step, in combination with close examination of raw concentration levels of lichens. Further validation using conventional air-monitoring by filter units should also prove beneficial.

“…Globally, mining is a major source of particulate matter. Mining activities play an important but underappreciated role in the generation of contaminated atmospheric dust and aerosol and the transport of metal and metalloid contaminants (Csavina et al 2012a;Meyer et al 2015). Coarse particles form a large proportion of resulting dust particles and are usually too heavy to travel far, although they may still contribute to exposure of workers and nearby residents (Barbieri et al 2014;Zota et al 2016).…”

“…Fine particles (PM 10 or smaller), such as those resulting from smelting operations or found in slag dumps or arising from the erosion of contaminated soil, disperse readily into the environment, often in association with aerosols, and may travel quite a lot further than anticipated (Reynolds et al 2010;Meyer et al 2015;Yu et al 2019). Fine particles also penetrate more deeply throughout the respiratory system and are more likely to result in adverse health effects (https://www.esrl.noaa.gov/gmd/about/ airquality.html; Csavina et al 2012a, b;Entwistle et al 2019 and references therein).…”

Mining is bad for health: a voyage of discovery

Mining continues to be a dangerous activity, whether large-scale industrial mining or small-scale artisanal mining. Not only are there accidents, but exposure to dust and toxins, along with stress from the working environment or managerial pressures, give rise to a range of diseases that affect miners. I look at mining and health from various personal perspectives: that of the ordinary man (much of life depends on mined elements in the house, car and phone); as a member of the Society for Environmental Geochemistry and Health (environmental contamination and degradation leads to ill health in nearby communities); as a public health doctor (mining health is affected by many factors, usually acting in a mix, ranging from individual inheritancegenetic makeup, sex, age; personal choices-diet, lifestyle; living conditions-employment, war; social support-family, local community; environmental conditions-education, work; to national and international constraints-trade, economy, natural world); as a volunteer (mining health costs are not restricted to miners or industry but borne by everyone who partakes of mining benefits-all of us); and as a lay preacher (the current global economy concentrates on profit at the expense of the health of miners). Partnership working by academics with communities, government and industry should develop evidencebased solutions. Employment, health, economic stability and environmental protection need not be mutually exclusive. We all need to act.
