The Boac-Makulapnit River (The Philippines) is contaminated with heavy metals primarily due to acid mine drainage (AMD). Heavy-metal levels in river water, sediment, and algae suggest that Cu is the primary contaminant in this system. Copper concentrations decrease longitudinally, indicating a contamination gradient away from the mine. This is also reflected in the whole-body metal concentration of the caddisfly Hydropsyche, wherein higher Cu levels are observed in upstream stations (677-980… CONTINUE READING
