The profundal sediment of many lakes is contaminated by heavy metals and persistent organic pollutants (POPs) deposited from the atmosphere, yet there has been little assessment of the biological effects of these toxicants. A Tier I sediment ecological risk assessment of profundal lake sediment that covers the range of contamination in the UK and Ireland was completed. Three laboratory sediment bioassays were used, Daphnia magna 7-day survival and reproduction, Gammarus pulex 14-day survival and growth and Chironomus riparius 10-day survival and growth/reproduction, and the concentrations of seven heavy metals and four groups of POPs (polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls, organochlorine pesticides and polybrominated diphenyl ethers) were determined.
