Summary

Researchers review how environmental factors alter the bioavailability and toxicity of marine sediment contaminants — including lead, mercury, organochlorine pesticides, antibiotics, and micro- and nanoplastics — examining how sediment chemistry, organic matter, and physical conditions interact to determine pollutant uptake and harm to marine organisms.

This chapter deals with the aspects responsible for changing the bioavailability and toxicity of organochlorine pesticides, antibiotics, mercury, and lead in marine and oceanic sediments. In this context, integrated discussions, which contemplated the effects of...
