Toxicity Of Aluminium In Seawater: Diatom Sensitivity, Megan Gillmore

Science, Medicine & Health - Honours Theses

Although recognised as a nonessential metal, aluminium was long considered virtually innocuous to marine organisms, largely because of the very low concentrations of aluminium naturally occurring in the marine environment. It is now clear however, that human activities are contributing to elevated concentrations of aluminium in industrialized harbours and coastal waters of Australia, which have the potential for adverse impacts on marine organisms. Toxicity testing recently conducted on a suite of marine algae, invertebrates and fish to derive a new ANZECC water quality guideline trigger value for the protection of organisms from aluminium identified marine diatoms (Bacillariophyceae) were amongst the …
