Waterborne nickel bioaccumulation in Gammarus pulex: Comparison of mechanistic models and influence of water cationic composition

Abstract: The biodynamic and saturation models offer promising lines of enquiry to predict the bioaccumulation of metals by aquatic organisms. However, in order to construct these models, the accumulation strategies have to be defined for each metal/organism couple in controlled conditions. This study aims at modelling the waterborne bioaccumulation of Ni and the influence of the water's geochemical properties on this process in a crustacean that is widely distributed in Europe, Gammarus pulex. In the laboratory, G. pul… Show more

“…The ratio I max /K corresponds to k umax that is the maximal uptake rate. As detailed in Lebrun et al (2011), the saturation model was constructed by combining Eqs. (2) and (3), which allowed the calculation of Cu bioaccumulation at the steady state as follows:…”

“…Pools of 5 gammarids were sampled at 0.5, 1, 2 and 5 days for each exposure condition. Before being frozen at -20°C, gammarids were rinsed with 2 and 0.5 mM EDTA, then twice with ultrapure waters for 1 min, so as to remove the metal potentially adsorbed on the organisms (Lebrun et al 2011).…”
