Bioavailability, Bioaccessibility and Mobility of Environmental Contaminants
Methods to assess the bioavailability of POPs and metals in the environment are discussed. The particular approaches considered are:
- non-exhaustive extraction techniques
- single extraction techniques
- sequential extraction techniques
- use of cyclodextrin and surfactants
- in-vitro gastrointestinal methods including physiological-based extraction test
- the use of bioasssays including earthworms.
Finally, selected case studies highlight the importance of determining the bioavailability of POPs and metals.
