Elemental concentrations and in vitro bioaccessibility in Canadian background soils

Environmental Geochemistry and Health, 2016
Elemental concentrations and bioaccessibility were determined in background soils collected in Canada as part of the North American Geochemical Landscapes Project. The concentrations of As, Cr, Cu, Co, Ni and Zn were higher in the C-horizon (parent material) compared to 0-5 cm (surface soil), and this observation along with the regional distribution ...

Bioaccessibility of arsenic and cadmium assessed for in vitro bioaccessibility in spiked soils and their interaction during the Unified BARGE Method (UBM) extraction [PDF]

Chemosphere, 2016
Recent decades have seen a growing popularity of in vitro bioaccessibility being utilised as a screening tool in human health risk assessment. However the existing bioaccessibility studies only focus on single contaminant. Considering human are likely to

Study on the bioaccessibility and bioavailability of Cd in contaminated rice in vitro and in vivo

Journal of Food Science, 2021
Abstract Cadmium (Cd) is a widespread heavy metal pollutant in the environment that damages human health. In this study, the bioaccessibility and bioavailability of Cd in different Cd‐contaminated rice (low pollution level cadmium rice (Rice‐L, 0.111 mg/kg), medium pollution level cadmium ...

In vitro bioaccessibility evaluation of chlorophyll pigments in single and binary carriers

Food Chemistry, 2023
Chlorophyll was extracted and microencapsulated using different carrier agents. Subsequently, in vitro digestion was performed, and the bioaccessibility of chlorophyll in the different encapsulation systems was carried out. The zeta potential, particle size, and PDI were significantly modified after the micellarization of digested microcapsules.

Comprehensive review on in vitro bioaccessibility of mercury in various foodstuffs

Journal of Hazardous Materials
Accurate assessment of dietary mercury (Hg) exposure and effective risk mitigation rely on a thorough understanding of its bioaccessibility. However, current knowledge of Hg bioaccessibility remains fragmented, with individual studies focusing on specific food types and influencing factors.

Estimation of Arsenic Bioaccessibility in Edible Seaweed by an in Vitro Digestion Method

Journal of Agricultural and Food Chemistry, 2003
The aim of this study was to examine the bioaccessibility (maximum soluble concentration in gastrointestinal medium) of total (AsT) and inorganic (AsI) arsenic contents and the effect on them of cooking edible seaweed, a food of great interest because of its high As content.

Development of an In Vitro Digestion Model for Estimating the Bioaccessibility of Soil Contaminants

Archives of Environmental Contamination and Toxicology, 2003
Soil ingestion can be a major route of human exposure to many immobile soil contaminants. The present risk assessment is based on toxicity studies in which contaminants are typically ingested in liquid or food matrices. The difference in bioavailability of contaminants ingested in a soil matrix is not taken into account.

In vitro assessment of arsenic bioaccessibility in contaminated (anthropogenic and geogenic) soils

Chemosphere, 2007
Arsenic (As) bioaccessibility in contaminated soils (n=50) was assessed using the simplified bioaccessibility extraction test (SBET). Soils used in the study were collected from sites where As was used as an herbicide (railway corridor) or pesticide (cattle dip sites), from former gold mines and from highly mineralised locations containing geogenic As ...

In vivo oral bioavailability of fish mercury and comparison with in vitro bioaccessibility

Science of The Total Environment, 2019
Fish consumption is considered to be a major human exposure route for mercury (Hg), but assessing the actual Hg bioavailability from consumed fish is challenging. In this study, we conducted both in vivo bioavailability (using a mouse model) and in vitro bioaccessibility (using various gastrointestinal digestion methods) assessments of Hg from consumed

Implications of in vitro bioaccessibility differences for the assessment of risks of metals to bats

Environmental Toxicology and Chemistry, 2014
Abstract   Food chain modeling is often used to assess the risks of chemical contaminants to wildlife. In modeling efforts, bioaccessibility from different dietary components is assumed to be similar.
