Effects of dissolved mercury on embryogenesis, survival, growth of Mytilus galloprovincialis mussel larvae

The effects of Hg concentrations ranging from 0 (control) to 1024 µg 1-1 upon embryogenesis, survival and growth of Mytilus galloprovincialis mussel larvae were investigated . Embryogenesis was abnormal in 50 % of the individuals at 10µg 1-1. The 48 h LC50 for D-shaped, early umbonate, late umbonate...
