Assessment of the Oral Bioavailability of Organic Contaminants in Humansccurate estimation of the human risks than the usage of total concentration. This is important for exposure assessment for children in relation to their hand-to-mouth activities. For example significant reductions of the bioavailability of long-term contaminated soils have been demonstrated using va

Why Biodegradable Chemicals Persist in the Environment? A Look at Bioavailability soils and sediments. This chapter examines this – commonly neglected – contradictory face of persistence assessments from the light of the latest advancements in bioavailability science. They include the microbial influences on bioavailability, the different sorption capacities of carbonaceous comp

Bioavailability as a Microbial System Property: Lessons Learned from Biodegradation in the Mycosphers a microbial systems property. In this chapter we summarize recent research on microbial ecology of contaminant biodegradation in the mycosphere (i.e., the microhabitat surrounding and affected by mycelia). By forming unique transport networks, mycelial fungi are highly adapted to cope with complex

Bioavailability and Bioaccessibility of Hydrophobic Organic Contaminants in Soil and Associated Deso conservative approach. Such conservatism makes traditional risk assessment approaches and contaminated land decision-making expensive. The risk-based approach to contaminated land management strives to identify and manage the potential risks of significant harm being caused to humans and ecological

Passive Sampling for Determination of the Dissolved Concentrations and Chemical Activities of Organiompound bioavailability plays a role but also for several abiotic processes. However, determining these is challenging due to their low levels and sorption to dissolved organic matter. Here, passive sampling can play a role and involves bringing an inert polymer into direct contact with the soil or
