“…Our analyses showed inconsistent and generally insignificant effects of poverty on the heavy metal contamination of soil. We observed a significant positive relationship between poverty and cadmium contamination, which agreed with many past studies that reported elevated soil-metal contamination for poverty filled areas [2,21,25,27]. In further analysis, we found that poverty-stricken individuals were more likely to be directly exposed to chromium, selenium, and silver (Figure S1), but indirectly exposed to other metals via closer proximity to emission sources.…”

(1) Background: Field monitoring data for addressing the disproportional burden of exposure to soil contamination in communities of minority and low socioeconomic status (SES) are sparse. This study aims to examine the association between soil heavy metal levels, SES, and racial composition. (2) Methods: A total of 423 soil samples were collected in the urban areas of eight cities across six Southern states in the U.S., in 2015. Samples were analyzed using inductively coupled plasma–mass spectrometry (ICP–MS) for eight heavy metals. The association was examined with mixed models with the log-transformed metal concentrations as the dependent variables and rankings of low-income or minority percentages as the explanatory variables. (3) Results: Model results showed that soil metal concentrations were significantly associated with rankings of poverty and minority percentages. The cadmium concentration significantly increased by 4.7% (p-value < 0.01), for every 10 percentiles of increase in poverty rank. For every 10 percentiles of increase in minority rank, the soil concentrations were significantly up (p-values < 0.01) for arsenic (13.5%), cadmium (5.5%), and lead (10.6%). Minority rank had significant direct effects on both arsenic and lead. (4) Conclusions: The findings confirmed elevated heavy metal contamination in urban soil in low-income and/or predominantly minority communities.

“…HQ and HI were calculated after the chronic daily intake (CDI) was determined (Gholampour and Gitipour, 2022). Kanda et al (2020) described how significant the CDI risk is by the ingestion of a single trace element over a long period of time, and is computed for children and adults. This is expressed in equation 6 and 7.…”

Geoelectrical method and physiochemical analyses were applied to obtain subsurface resistivity variation and water quality assessment respectively in Fountain University, Osogbo, Osun State. A young academic institution with a measurable growing population is seriously concerned with the hygienic situation within its environment, especially water quantity and quality. The geophysical method was employed to determine the subsurface groundwater potentials via vertical electrical sounding (VES) using the Schlumberger array. Ten (10) water samples were collected from different locations within the study area and analyzed for physiochemical parameters and trace metals using standard procedure. Water quality index (WQI), exceedance, and human health risk index were determined. All parameters estimated were below the WHO permissible limits except the pH and iron concentration. WQI values of the ten collected water samples reflected 100% excellent grade for drinking. Chronic dietary intake (CDI) is in the order of Fe >Zn > Cu for both children and adults. The VES (9 location points were studied) data revealed four to five geo-electric layers which corresponded to the topsoil, lateritic clay, weathered layer, fractured basement, and fresh basement with thickness ranges of 0.5 to 39.6 m, while resistivity values vary from 27.5 to 5432.6 Ωm. The study observed and recommended that boreholes could be sunk at VES 1, 6, and 7 at depths between 26.1 to 39.6 m for exploitation of good quality water along with continuous monitoring of groundwater quality to maintain the good water quality area, hence the safety of the environment.

Limited information is available on trace element-water contamination and health risk assessment of small-scale intensive fish farming in low-income settings. Such information creates awareness among fish consumers, policy makers and the scientific community, regarding dietary exposure and health risks for not well-reported settings. The concentrations of potentially toxic trace elements in water, sediment and fish (T. rendalli, O. nitloticus and M. salmoides) were determined by spectrometry. The ecological and potential human health risks were assessed for Magobo dam, NE Zimbabwe, using the Hakanson ecological approach and the United States Environmental Protection Agency risk-assessment model, respectively. Concentrations in water and sediment appeared to increase in the order: cadmium < arsenic < lead. They restricted water use for irrigation and human consumption. The potential ecological risk factors for individual trace elements were below the index range for low risk. The potential ecological risk index for the dam (7.20) did not constitute ecological risk. The concentrations of trace elements in fish significantly varied with species, length and tissue (p < 0.05). The concentrations of arsenic and lead in gills, liver and muscle for O. niloticus and arsenic in M. salmoides were greater than international maximum permissible limits for fish. The target cancer risk due to dietary exposure to arsenic in the three fish species was in the range 10-6. There is no obvious cancer risk to the exposed population.
