Journal of Environmental Geochemistry and Health

 

Environmental Geochemistry and Health is the Official Journal of the Society for Environmental Geochemistry and Health.  The journal publishes original research papers, research notes and reviews across the broad field of environmental geochemistry.

  • Environmental geochemistry establishes and explains links between the chemical composition of rocks and minerals and the health of plants, animals and people.
  • Beneficial elements regulate or promote enzymatic and hormonal activity, whereas other elements may be toxic.
  • Bedrock geochemistry controls the composition of soil and hence that of water and vegetation.
  • Pollution arising from the extraction and use of mineral resources distorts natural geochemical systems.
  • Geochemical surveys of soil, water and plants show how major and trace elements are distributed geographically.
  • Associated epidemiological studies reveal the possibility of links between the geochemical environment and disease.
  • Experimental research illuminates the nature or consequences of natural geochemical processes.

High quality research papers or reviews dealing with any aspect of environmental geochemistry are welcomed.  Submission of papers which directly link health and the environment are particularly encouraged.  Papers may be theoretical, interpretative or experimental.  Authors shoud refer to  www.springer.com/10653 for more information and authors' instructions.

  • Trace metal content in inhalable particulate matter (PM 2.5–10 and PM 2.5 ) collected from historical mine waste deposits using a laboratory-based approach 2016-05-05

    Abstract

    Mine wastes and tailings are considered hazardous to human health because of their potential to generate large quantities of highly toxic emissions of particulate matter (PM). Human exposure to As and other trace metals in PM may occur via inhalation of airborne particulates or through ingestion of contaminated dust. This study describes a laboratory-based method for extracting PM2.5–10 (coarse) and PM2.5 (fine) particles from As-rich mine waste samples collected from an historical gold mining region in regional, Victoria, Australia. We also report on the trace metal and metalloid content of the coarse and fine fraction, with an emphasis on As as an element of potential concern. Laser diffraction analysis showed that the proportions of coarse and fine particles in the bulk samples ranged between 3.4–26.6 and 0.6–7.6 %, respectively. Arsenic concentrations were greater in the fine fraction (1680–26,100 mg kg−1) compared with the coarse fraction (1210–22,000 mg kg−1), and Co, Fe, Mn, Ni, Sb and Zn were found to be present in the fine fraction at levels around twice those occurring in the coarse. These results are of particular concern given that fine particles can accumulate in the human respiratory system. Our study demonstrates that mine wastes may be an important source of metal-enriched PM for mining communities.

  • Characterization and speciation of mercury in mosses and lichens from the high-altitude Tibetan Plateau 2016-05-03

    Abstract

    The accumulation and species of mercury (Hg) in mosses and lichens collected from high-altitude Tibetan Plateau were studied. The altitudes of the sampling sites spanned from 1983 to 5147 m, and a total of 130 mosses and 52 lichens were analyzed. The total mercury (THg) contents in mosses and lichens were in the ranges of 13.1–273.0 and 20.2–345.9 ng/g, respectively. The average ratios of methylmercury (MeHg) in THg in mosses and lichens were 2.4 % (0.3–11.1 %) and 2.7 % (0.4–9.6 %), respectively, which were higher than those values reported in other regions. The contents of THg in both mosses and lichens were not correlated with the THg in soils (p > 0.05). The lipid contents displayed a significantly positive correlation with concentrations of MeHg in mosses (r = 0.461, p < 0.01, n = 90), but not in lichens. The correlations between Hg contents in mosses and the altitudes, latitudes and longitudes of sampling sites indicated the mountain trapping and spatial deposition of Hg in the Tibetan Plateau.

  • Assessment of potentially harmful elements pollution in the Calore River basin (Southern Italy) 2016-05-03

    Abstract

    The geographical distribution of concentration values for harmful elements was determined in the Campania region, Italy. The study area consists of the drainage basin of the River Calore, a tributary of the river Volturno, the largest Southern Italian river. The results provide reliable analytical data allowing a quantitative assessment of the trace element pollution threat to the ecosystem and human health. Altogether 562 stream sediment samples were collected at a sampling density of 1 site per 5 km2. All samples were air-dried, sieved to <100 mesh fraction and analyzed for 37 elements after an aqua regia extraction by a combination of ICP-AES and ICP-MS. In addition to elemental analysis, gamma-ray spectrometry data were collected (a total of 562 measurements) using a hand-held Scintrex GRS-500 spectrometer. Statistical analyses were performed to show the single-element distribution and the distribution of elemental association factor scores resulting from R-mode factor analyses. Maps showing element distributions were made using GeoDAS and ArcGIS software. Our study showed that, despite evidence from concentrations of many elements for enrichment over natural background values, the spatial distribution of major and trace elements in Calore River basin is determined mostly by geogenic factors. The southwestern area of the basin highlighted an enrichment of many elements potentially harmful for human health and other living organisms (Al, Fe, K, Na, As, Cd, La, Pb, Th, Tl, U); however, these anomalies are due to the presence of pyroclastic and alkaline volcanic lithologies. Even where sedimentary lithologies occur, many harmful elements (Co, Cr, Mn, Ni) showed high concentration levels due to natural origins. Conversely, a strong heavy metal contamination (Pb, Zn, Cu, Sb, Ag, Au, Hg), due to an anthropogenic contribution, is highlighted in many areas characterized by the presence of road junctions, urban settlements and industrial areas. The enrichment factor of these elements is 3–4 times higher than the background values. The southwestern area of the basin is characterized by a moderate/high degree of contamination, just where the two busiest roads of the area run and the highest concentration of industries occurs.
