Hg release and Hg nanoparticle formation upon flooding of an agriculturally used fluvisol

Autor: Isabelle A.M. Worms, Adrien Mestrot, Lorenz Gfeller, Andrea Weber, Vera I. Slaveykova

Soils in legacy sites of chlor-alkali and acetaldehyde production are point sources of mercury (Hg) to downstream eco-systems. Flooding and agricultural activities may influence the fate of Hg by altering redox conditions, microbial activity and carb
