▪ Abstract Because it is very toxic and accumulates in organisms, particularly in fish, mercury
is an important pollutant and one of the most studied. Nonetheless we still have an …

The bioaccumulation of trace elements in aquatic organisms can be described with a kinetic
model that includes linear expressions for uptake and elimination from dissolved and dietary …

Each year ecotoxicological problems become increasingly complex and encompass
broader spatial and temporal scales. Our practical understanding must evolve accordingly to …

Recent studies have shown the utility of delta (15) N to model trophic structure and
contaminant bioaccumulation in aquatic food webs. However, cross-system comparisons in …

Les rapports d'un isotope stable de l'azote (delta 15N) sont couramment utilisés pour
représenter la structure trophique des systèmes aquatiques; pourtant, la capacité du delta …

THE nitrogen pools of animals are enriched in 15N relative to their food1, with the top
predators having the highest concentrations of this stable isotope2. The use of δ15N to …

Current paradigms regarding the bioaccumulation of mercury are rooted in observations that
monomethyl mercury (meHg) biomagnifies along pelagic food chains. However …

With contributions from more than 75 international experts, this second edition focuses on
toxic substances and how they affect ecosystems worldwide. It presents methods for …

A field experiment was conducted to determine the degree to which fish accumulated
methylmercury (MeHg) via their food or via passive uptake from water through the gills …
