Arsenic and bacteria

Un exemple de recherche pour la dépollution d'un site minier

  00:25:00  1998  SD 4/3  Color  Sound

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.
