摘要: Publisher Summary This chapter presents an overview of the current understanding bioavailability, definitions and their limitations, methods for assessment bioavailability implications to risk assessment. Bioavailability is used as key indicator potential that chemicals pose environment human health. From a regulatory perspective, influence decision-making greatest where: contaminant driver at site; default assumptions made during affect final clean-up goal are inappropriate; significant change remedial goals likely; conditions present site unlikely substantially over time; public acceptance high. In this chapter, elaborated. Estimating or measuring bioaccumulation directly from environmental media discussed also estimating using soil properties described. Extractants assessing bioremediation reviewed bioaccessibility discussed. Details provided.
