“…PXRF devices have also been used successfully for in-field environmental screening to detect the occurrence of elevated concentrations of metals in the soil (Carr et al, 2008;Fujimori and Takigami, 2014;Kalnicky and Singhvi, 2001;Radu et al, 2013;Weindorf et al, 2013b). For example, Weindorf et al (2013b) used a PXRF spectrometer to survey a site in Zlatna, Romania, with a history of mining/smelting operations.…”

a b s t r a c tThere are tens of millions of contaminated soil sites in the world, and with an increasing population and associated risk there is a growing pressure to remediate them. A barrier to remediation is the lack of cost-effective approaches to assessment. Soil contaminants include a wide range of natural and synthetic metallic and organic compounds and minerals thus making analytical costs potentially very large. Further, soil contaminants show a large degree of spatial variation which increases the burden on sampling costs. This paper reviews potentially cost-effective methods for measurement, sampling design, and assessment. Current tiered investigation approaches and sampling strategies can be improved by using new technologies such as proximal sensing. Design of sampling can be aided by on-the-go proximal soil sensing; and expedited by subsequent adaptive spatially optimal sampling and prediction procedures enabled by field spectroscopic methods and advanced geostatistics. Field deployment of portable Visible & Near Infrared [wavelength 400-2500 nm] (Vis-NIR) and X-ray fluorescence (PXRF) spectroscopies will require special calibration approaches but show huge potential for synergistic use. The use of mid-infrared spectroscopy [wavelength 2500-25,000 nm, wavenumber 4000-400 cm −1 ] (MIR) for field implementation requires further adaptive research. We propose an integrated field-deployable methodology as a basis for further developments. Crown

“…Recently, proximal sensing tools such as the portable X-ray fluorescence (PXRF) spectrometer have been applied to contaminant quantification (Ran et al 2014), soil chemical property predictions (Sharma et al 2014(Sharma et al , 2015, horizon differentiation (Weindorf et al 2012a, b), and integrated with geographic information system (GIS) data for contaminant mapping (Weindorf et al 2013) in various landscapes. Accordingly, the PXRF can be deployed in the field to rapidly determine elemental concentrations to help advance survey efforts and identify fields or areas within fields that have high pollutant concentrations.…”

This study examined and compared arsenic (As) and other element [copper (Cu), iron (Fe), potassium (K), manganese (Mn), rubidium (Rb), and zinc (Zn)] distribution, as well as their interactions in historically irrigated and non-irrigated semi-arid agricultural soils of the Southern High Plains (SHP) in the USA, using findings from a portable X-ray fluorescence spectrometer. The portable X-ray fluorescence (PXRF) findings revealed that the concentrations of As (5.1 vs. 3.1 mg kg(-1)), Cu (7.2 vs. 6.2), Fe (7398 vs. 5677), K (8638 vs. 7061), Mn (80 vs. 68), Rb (36 vs. 27), and Zn (19.3 vs. 13.8) were higher in the historically irrigated field compared to the non-irrigated and, when examined within depths, were consistently and significantly higher (P<0.001) in the subsurface soils of the non-irrigated field, a trend not evident in the irrigated field. The strengths of the correlation among elements were higher in the non-irrigated field compared to the irrigated (average R of 0.60 vs. 0.54), suggesting a possible external input of these pollutants in the historically irrigated field which could have altered the natural background concentration and association among them. Furthermore, findings from principal component analysis (PCA) indicated that As, Mn, Rb, Fe, Zn, and K were more closely associated in the non-irrigated field and likely of lithogenic origin. The observed differences in elemental concentration and interaction between the irrigated and non-irrigated soils support the hypothesis that water from the local aquifer could be a potential source of pollutant addition to these semi-arid alkaline soils.

Abstract. The idea that human health is tied to the soil is not a new one. As far back as circa 1400 BC the Bible depicts Moses as understanding that fertile soil was essential to the well-being of his people. In 400 BC the Greek philosopher Hippocrates provided a list of things that should be considered in a proper medical evaluation, including the properties of the local ground. By the late 1700s and early 1800s, American farmers had recognized that soil properties had some connection to human health. In the modern world, we recognize that soils have a distinct influence on human health. We recognize that soils influence (1) food availability and quality (food security), (2) human contact with various chemicals, and (3) human contact with various pathogens. Soils and human health studies include investigations into nutrient supply through the food chain and routes of exposure to chemicals and pathogens. However, making strong, scientific connections between soils and human health can be difficult. There are multiple variables to consider in the soil environment, meaning traditional scientific studies that seek to isolate and manipulate a single variable often do not provide meaningful data. The complete study of soils and human health also involves many different specialties such as soil scientists, toxicologists, medical professionals, anthropologists, etc. These groups do not traditionally work together on research projects, and do not always effectively communicate with one another. Climate change and how it will affect the soil environment/ecosystem going into the future is another variable affecting the relationship between soils and health. Future successes in soils and human health research will require effectively addressing difficult issues such as these.
