| Abstract: | ediments are often considered as a sink of mercury,but they can also become a source of mercury accumulation in many benthic invertebrates.Here we review the recent progresses in studying the bioavailability of sedimentary mercury(both inorganic mercury and methylmercury).These include the in vitro digestive extraction of mercury in sediments and the effects of biogeochemical factors on the bioavailability of mercury in sediments(mercury concentration in sediments,sediment composition,contact time between m... |
