Arsenic Uptake by Two Tolerant Grass Species: <i>Holcus lanatus</i> and <i>Agrostis capillaris</i> Growing in Soils Contaminated by Historical Mining
The study focused on two grass species <i>Holcus lanatus</i> and <i>Agrostis capillaris</i> abundant in the sites of former As mining and processing in the Sudetes. Arsenic uptake from soils was examined to assess a risk associated with its accumulation in grass shoots and to...

The study focused on two grass species <i>Holcus lanatus</i> and <i>Agrostis capillaris</i> abundant in the sites of former As mining and processing in the Sudetes.
