The distribution of dissolved aluminum in Atlantic salmon ( Salmo salar ) rivers of Atlantic Canada and its potential effect on aquatic populations
Studies from the 1980s concluded that aluminum (Al) was not a significant contributor to Atlantic salmon ( Salmo salar ) toxicity in Nova Scotia, located on Canada’s Atlantic coast, because of the presence of dissolved organic matter that rendered ionic Al (Al i ) biologically inaccessible. Since th...
