Aluminium Induced DNA-damage and Oxidative Stress in Cultures of the Marine Sponge Hymeniacidon perlevis
Aluminium is the most abundant element in the earth crust, and has no known biological function. However, it is an established neurotoxicant in its trivalent oxidation state, with exposure resulting in neurodegenerative diseases like Parkinson’s disease and presenile dementia. Although, the potentia...

Aluminium is the most abundant element in the earth crust, and has no known biological function.
