Bioaccessible and non-bioaccessible fractions of soil arsenic

Journal of Environmental Science and Health, Part A, 2013
In order for in vitro methods to become widely accepted as tools that accurately assess soil arsenic (As) exposure through the oral ingestion pathway, a better understanding is needed regarding which fractions of soil As are being measured in the in vitro extraction.

Bioaccessibility testing of cobalt compounds

Journal of Environmental Monitoring, 2003
Testing of metal compounds for solubility in artificial fluids has been used for many years to assist determining human health risk from exposure to specific compounds of concern. In lieu of obtaining bioavailability data from samples of urine, blood, or other tissues, these studies measured solubility of compounds in various artificial fluids as a ...

Iron amendments to reduce bioaccessible arsenic

Journal of Hazardous Materials, 2014
Former sugarcane lands on the Island of Hawaii have elevated levels of soil arsenic (As) from historical use of arsenical pesticides. The bioaccessible fraction of total As (AsTOT), a measure of the potential for human As uptake by incidental ingestion of soil, is used in the assessment of human health risk and the determination of the need for ...

Bioaccessibility of PAH from Danish soils

Journal of Environmental Science and Health, Part A, 2007
A test method for the determination of PAH relative bioaccessibility from contaminated soils was implemented and validated for use in risk assessment of soils from contaminated sites meeting performance requirement set for evaluation against regulatory limits.

Bioaccessibility of some minerals in infant formulas

Journal of Food Science and Technology, 2021
To guarantee the adequate intake of nutrients a variety of food supplementation (including infant formulas) has been used to ensure the nutrition of infants. Considering that the total concentration of nutrients is not enough to determine whether the food provides all the nutritional needs, the objective of this study was to evaluate the total ...

Predicting PAH bioremediation efficacy using bioaccessibility assessment tools: Validation of PAH biodegradation–bioaccessibility correlations

International Biodeterioration & Biodegradation, 2014
Abstract Hydroxypropyl-β-cyclodextrin (HP-β-CD) may be utilised as a selective extractant to assesses the amount of PAHs in contaminated soil that are potentially available for biodegradation (i.e. the bioaccessible fraction). In this study, HP-β-CD extraction and PAH biodegradation (using enhanced natural attenuation) was assessed in 15 PAH ...

Model Polymer Release System Study of PAH Bioaccessibility:  The Relationship between “Rapid” Release and Bioaccessibility

Environmental Science & Technology, 2005
This paper examines bacterial uptake of polycyclic aromatic hydrocarbons (PAHs) entrained within model polymer release systems (MPRSs) whose release kinetics, particularly for operationally defined "slow" release, are similarto PAH release kinetics from sediments and soils.
