“…Soils bear a legacy of hundreds to thousands of years of human occupation and industrialization (e.g., Bellinger, 2011;Chambers et al, 2016;Filippelli & Taylor, 2018). Some pollutants, including many metals with poor mobility in soil media (i.e., lead, cadmium, and copper), have soil residence times on the order of hundreds to thousands of years.…”

New Approaches to Identifying and Reducing the Global Burden of Disease From Pollution

Pollution from multiple sources causes significant disease and death worldwide. Some sources are legacy, such as heavy metals accumulated in soils, and some are current, such as particulate matter. Because the global burden of disease from pollution is so high, it is important to identify legacy and current sources and to develop and implement effective techniques to reduce human exposure. But many limitations exist in our understanding of the distribution and transport processes of pollutants themselves, as well as the complicated overprint of human behavior and susceptibility. New approaches are being developed to identify and eliminate pollution in multiple environments. Community-scale detection of geogenic arsenic and fluoride in Bangladesh is helping to map the distribution of these harmful elements in drinking water. Biosensors such as bees and their honey are being used to measure heavy metal contamination in cities such as Vancouver and Sydney. Drone-based remote sensors are being used to map metal hot spots in soils from former mining regions in Zambia and Mozambique. The explosion of low-cost air monitors has allowed researchers to build dense air quality sensing networks to capture ephemeral and local releases of harmful materials, building on other developments in personal exposure sensing. And citizen science is helping communities without adequate resources measure their own environments and in this way gain agency in controlling local pollution exposure sources and/or alerting authorities to environmental hazards. The future of GeoHealth will depend on building on these developments and others to protect a growing population from multiple pollution exposure risks. Plain Language SummaryThe health burdens of legacy contaminants, and the continuing global health burdens of current pollution, are crippling both global health and well-being. Much of the exposure science on these relatively well-studied pollutants is known, as is the general toxicity of past pollutants. But there is a great distance between understanding the toxicity and exposure sources of environmental pollutants and applying that knowledge in practical and just ways. This contribution summarizes several major repositories and ongoing sources of soil, dust, and air pollution and addresses the harmful effects from exposure to these. We also highlight some examples of the future of GeoHealth research in this area by providing case studies of current novel approaches that focus on bridging the science of pollution sources and distribution with real applications at the community level to reduce pollution's role in the global burden of disease.

“…In addition, distribution characteristics of concentrations of As, Cr, Ni, Pb, Zn, and Cu in the southeast are different from Hg and Cd. Utilization and improper discarding of paint, cement, and other building materials for residential land developed in this area after 2009 may be the major anthropogenic sources of these elements [5]. However, low PLI value indicates that general accumulation of heavy metals in this area is not critical.…”

“…As the urban boundary rapidly sprawls, land conversions, along with the change in production, are not only encroaching on the quantity of cultivated lands, but also posing a threat to soil quality and food security [3,4]. Anthropogenic activities carried by different land use types are reported to release varying volumes of heavy metals [5,6,7]. Therefore, spatial variations in land use pattern will constitute one of the major artificial influences on the spatial redistribution of soil heavy metals.…”

Under rapid urban sprawl in Northeast China, land conversions are not only encroaching on the quantity of cultivated lands, but also posing a great threat to black soil conservation and food security. This study’s aim is to explore the spatial relationship between comprehensive cultivated soil heavy metal pollution and peri-urban land use patterns in the black soil region. We applied spatial lag regression to analyze the relationship between PLI (pollution load index) and influencing factors of land use by taking suburban cultivated land of Changchun Kuancheng District as an empirical case. The results indicate the following: (1) Similar spatial distribution characteristics are detected between Pb, Cu, and Zn, between Cr and Ni, and between Hg and Cd. The Yitong River catchment in the central region, and the residential community of Lanjia County in the west, are the main hotspots for eight heavy metals and PLI. Beihu Wetland Park, with a larger-area distribution of ecological land in the southeast, has low level for both heavy metal concentrations and PLI values. Spatial distribution characteristics of cultivated heavy metals are related to types of surrounding land use and industry; (2) Spatial lag regression has a better fit for PLI than the ordinary least squares regression. The regression results indicate the inverse relationship between heavy metal pollution degree and distance from long-standing residential land and surface water. Following rapid urban land expansion and a longer accumulation period, residential land sprawl is going to threaten cultivated land with heavy metal pollution in the suburban black soil region, and cultivated land irrigated with urban river water in the suburbs will have a higher tendency for heavy metal pollution.

“…Urban soils bear a lingering legacy of sometimes centuries of human occupation and industrialization (e.g., Bellinger, 2011;Chambers et al, 2016;Filippelli and Taylor, 2018). Among the many anthropogenic inputs to surface soils are metals, many of which, such as lead (Pb), have a very strong and permanent impact on human health and urban well-being.…”

An ambitious citizen-science effort in the city of Indianapolis (Indiana, USA) led to the collection and analysis of a large number of samples at the property scale, facilitating the analysis of differences in soil metal concentrations as a function of property location (i.e., dripline, yard, and street) and location within the city. This effort indicated that dripline soils had substantially higher values of lead and zinc than other soil locations on a given property, and this pattern was heightened in properties nearer the urban core. Soil lead values typically exceeded the levels deemed safe for children's play areas in the US (<400 ppm), and almost always exceeded safe gardening guidelines (<200 ppm). As a whole, this study identified locations within properties, and cities, that exhibited the highest exposure risk to children, and also exhibited the power of citizen science to produce data at a spatial scale (i.e., within a property boundary) that is usually impossible to feasibly collect in a typical research study.
