Seawater carbonate chemistry and chronic toxicity of olivine in the marine amphipod Gammarus locusta

Juvenile amphipods were exposed to natural Eastern Scheldt sediment (the Netherlands) mixed with various amounts of 3-99 µm olivine (expressed in % w/w) for 35 days. Various endpoints were measured including amphipod survival, growth, reproduction, and whole body element and TBARS concentrations. Furthermore, artificial seawater (ASW) temperature, pH, salinity, and concentrations of dissolved oxygen, various elements, dissolved organic carbon (DOC), and total alkalinity (TA) were analyzed.
