Environmental effects of aluminium | SpringerLink

Aluminium (Al), when present in high concentrations, has for long been recognised as a toxic agent to aquatic freshwater organisms,i.e. downstream industrial point sources of Al-rich process water. Today the environmental effects of aluminium are mainly a result of acidic precipitation; acidifiion of chments leads to increased Al- concentrations in soil solution and freshwaters.
