Arsenic and bacteria
Un exemple de recherche pour la dépollution d'un site minier
In the Gard region an old lead and zinc mine still contains waste material. Rain dissolves this into large quantities of arsenic, which flows into a stream in the area. Marc Leblanc, a CNRS researcher, analyzes the contaminated water and seeks to understand the complex chemical reactions produced in it. He demonstrates the function of aerobic bacteria which contribute to limiting the pollution.
