Metal bioaccessibility of soils in urban parks in Fredericton and Saint John, New Brunswick
… bioaccessibility was determined by an in vitro physiologically based extraction test (PBET). The risk associated with exposure to selected metals (including As, Ba, Cd, Co, Cu, Pb, Ni and Zn) in soil from the urban parks in New Brunswick studied was fairly low based on the total metals …

Bioaccessibility of metals in Toronto city parks
… in the soil samples as determined by an in-vitro physiologically based extraction test (PBET) were relatively high. Based on linear regression analyses there were no significant relationships between total metals and soil properties such as pH and total organic carbon (TOC). Generally there was …

Microplastics as Contaminant Vectors: Influencing the Bioaccessibility of Naphthalene from Freshwater
… from freshwater systems to the human gastrointestinal tract (GIT). The focus was on characterizing the sorption mechanisms of naphthalene and its bioaccessibility (i.e., an estimate of the fraction of an ingested dose that becomes soluble in gastro-intestinal fluids). Three types of MPs, …

Physico-chemical Characteristics and Environmental Fate of a Hydrolytically Degradable Cationic Flocculant
… was then subjected to in-vitro gastrointestinal (GI) digestions with simulated MFT (kaolin), a model contaminant (naphthalene), and simulated municipal wastewater (SMW). Modified physiologically based extraction tests (PBETs) were developed to estimate the bioaccessibility of …

Mineralogy, geochemistry and health impacts of earth materials consumed by humans in Vhembe District, Limpopo Province, South Africa
… have been adjudged for human geophagic practice. Tests conducted include: colour, pH, electrical conductivity (EC), cation exchange capacity (CEC), textures and occurrence of beneficial bacteria in the samples. Colour ranged from red, yellow to dark grey through various shades of brown. The pH of …
