“…One attempt to provide a consistent, available platform for citizen-involved research and to communicate potential risks and provide interactive tools for assessment is provided by MapMyEnvironment.com (to disclose this is an app developed to collect data from and expand the breadth and depth of citizen science programs currently run by several of this paper's authors). At this point, this platform maps soil and dust geochemistry in a consistent manner across multiple programs and additionally can provide the capability of adding user-added data on these media (Doyi et al, 2019). We envision the system accommodating multiple additional data layers, including water chemistry, more detailed information about indoor dust and the dust exposome (including allergens, flame-retardant chemicals, antimicrobial resistance, to name a few), and any variety of other geolocated data that is not necessarily collected for environmental compliance.…”

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.

“…The component also consisted of the highest percentage of Ni, Pb, and Cu (Figure S5b-d, respectively) released during moderate to high acid CISED extractions. Some authors indicate Ca as a typical soil component when associated to Si or Mg [15], which are indicative of a crustal source, while others suggest an association with the wear of asphalt concrete or building materials [12,[48][49][50]. At the time of dust collection, the house was being restored, and debris and building materials as concrete, plaster, and bricks were visible throughout the site, which, associated with the composition of the component, led us to interpret it as Ca-carbonates of anthropogenic origin.…”

“…Children are typically more susceptible to the impacts of acute and chronic environmental contaminant exposures because they are exposed to indoor dust accumulated on floors and other surfaces. Further, infants and children typically engage in more hand-to-mouth activity than other age groups, which might involve the placement of toys contaminated with dust in their mouth or the consumption of food with contaminated fingers [15]. There is, therefore, a necessity to identify and characterize the hazards associated with indoor dust to develop ways of reducing the associated risks and make our homes safer.…”

The main objectives of the present study were to (i) investigate the effects of mineralogy and solid-phase distribution on element bioaccessibility and (ii) perform a risk assessment to calculate the risks to human health via the ingestion pathway. Multiple discriminant analysis showed that the dust chemistry discriminates between indoor and outdoor samples. The solid-phase distribution of the elements in indoor dust indicated that a large proportion of zinc, nickel, lead, copper, and cobalt is associated with an aluminum oxy-hydroxides component, formed by the weathering of aluminum silicates. This component, which seems to influence the mobility of many trace elements, was identified for a group of indoor dust samples that probably had a considerable contribution from outdoor dust. An iron oxide component consisted of the highest percentage of chromium, arsenic, antimony, and tin, indicating low mobility for these elements. The bioaccessible fraction in the stomach phase from the unified BARGE method was generally high in zinc, cadmium, and lead and low in nickel, cobalt, copper, chromium, and antimony. Unlike other potentially toxic elements, copper and nickel associated with aluminum oxy-hydroxides and calcium carbonates were not extracted by the stomach solutions. These trace elements possibly form stable complexes with gastric fluid constituents such as pepsin and amino acid. Lead had a hazard quotient >1, which indicates the risk of non-carcinogenic health effects, especially for children.

“…Barium is strongly correlated with Pb and Zn (R> 0.86, p <0.001). The source of Pb in indoor dust varies from Pb-based paint sources to accumulation of automobile related petrol Pb depositions [52]. Barrio-Parra et al (2017) [63] revealed that the room in which the dust sample collected was a strong determinant of Zn levels.…”

The levels of metals associated with dust is higher in indoor environment as compared to settled dust or soil in the exterior counterpart in the urban centers. The metals can be transferred to human body via inhalation, ingestion and dermal contact upon exposure and pose a significant health problem. The primary objectives of this study are (i) to determine the levels of metals in home dust samples in Bolu, Turkey, (ii) to assess the associated health risk when citizens are exposed to these metals in indoor environment. To end this, sixteen vacuum cleaning bags containing dust were collected from the homes located in the city center of Bolu (Turkey) between November and December 2017. The collected samples were analyzed by employing Wavelength Dispersive X-Ray Fluorescence (WDXRF) spectrometer in terms
