Carl Nägeli, a Swiss botanist, discovered in 1893 that the ions of various metals and their alloys such as silver and copper, but also mercury, iron, lead, zinc, bismuth, gold, aluminium and others, have a toxic effect on microbial life by denaturing microbial enzymes and thus disrupting their metabolism.

Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and ...
