Soil ingestion by elastomeric seals
… present work shows that three stages of particle ingestion precede seal erosion, and that seals designed to interfere with each stage exhibit substantially longer operational life. The three stages of failure preceding seal erosion are as follows. The first stage occurs when small soil particles …

Soil ingestion and lead concentration in wildlife species
Problems related to estimating soil ingestion by wildlife species from analysis of feces were examined. Soil ingestion was investigated as a means by which wildlife may be exposed to environmental contaminants, particularly Pb. Titanium (Ti) and acid-insoluble residue (AIR) tracer methods for …

Elucidating fecal contamination exposure in low-income countries, the contribution from child feces disposal practices and soil ingestion, and links to child health
… children’s feces as a source of contamination, soil ingestion as an exposure point, and their effects on child health. First, the occurrence, magnitude, and distribution of fecal contamination and enteric pathogens were assessed along multiple transmission pathways for children in a …

Concentrations and In Vitro Bioaccessibility of Metals in Soils at Urban Green Spaces in Toronto, Ontario
… investigated metal concentrations and pH in 75 soil samples obtained from 25 urban green spaces within the City of Toronto. In vitro bioaccessibility was determined in eight of the samples as a surrogate for bioavailability. The mean concentrations of metals of interest, As, Cr, Cu, Ni, Pb, and …
