Elevated Methylmercury in Water and Aquatic Food Webs in Lagoons
We assessed mercury contamination of water, sediment, and selected aquatic biota from two lagoons in the Apostle Islands National Lakeshore (southern Lake Superior). These nearshore lagoon systems appear to be mercury-sensitive environments with unusually high rates of production of methylmercury, a highly toxic compound that readily bioaccumulates in aquatic food webs. Concentrations of methyl...
متن کاملFactors affecting methylmercury biomagnification by a widespread aquatic invertebrate predator, the phantom midge larvae Chaoborus.
MeHg biomagnification by the phantom midge Chaoborus in relation to MeHg concentrations in their prey and its migratory behavior was investigated in two Canadian Precambrian Shield lakes. Three Chaoborus species with contrasted migratory behavior were collected in a fishless and a fish-inhabited lake. All species accumulated MeHg through their ontogenic development. In the lake inhabited by fis...
متن کاملTrophic transfer of metals along freshwater food webs: Evidence of cadmium biomagnification in nature
We conducted a study with cadmium (Cd) and copper (Cu) in the delta of San Francisco Bay, using nitrogen and carbon stable isotopes to identify trophic position and food web structure. Cadmium is progressively enriched among trophic levels in discrete epiphyte-based food webs composed of macrophyte-dwelling invertebrates (the first link being epiphytic algae) and fishes (the first link being go...
متن کاملReducing methylmercury accumulation in the food webs of San Francisco Bay and its local watersheds.
San Francisco Bay (California, USA) and its local watersheds present an interesting case study in estuarine mercury (Hg) contamination. This review focuses on the most promising avenues for attempting to reduce methylmercury (MeHg) contamination in Bay Area aquatic food webs and identifying the scientific information that is most urgently needed to support these efforts. Concern for human expos...
متن کاملBenthic and Pelagic Pathways of Methylmercury Bioaccumulation in Estuarine Food Webs of the Northeast United States
Methylmercury (MeHg) is a contaminant of global concern that bioaccumulates and bioamagnifies in marine food webs. Lower trophic level fauna are important conduits of MeHg from sediment and water to estuarine and coastal fish harvested for human consumption. However, the sources and pathways of MeHg to these coastal fisheries are poorly known particularly the potential for transfer of MeHg from...
