Name and briefly describe the USEPA's four-step human health risk assessment paradigm.1 / 8

(1) Hazard identification — does the chemical cause an adverse effect, and in whom? (2) Dose-response assessment — how does the magnitude of exposure relate to the probability/severity of the effect? (3) Exposure assessment — how much of the chemical do people actually contact, via which pathways? (4) Risk characterization — combining dose-response and exposure information into a quantitative estimate of risk, with its uncertainties.

Define a metapopulation.1 / 8

A metapopulation is a 'population of populations' — a set of spatially discrete local populations occupying separate habitat patches, connected (or not) by occasional dispersal between patches, where any single local population may go extinct and be recolonized independently.
