Influence of hail suppression systems over silver content in the environment in Aragón (Spain). II: Water, sediments and biota

The silver content in soils the area surroundings of Gallocanta Lake (Aragón, NE Spain) is lower than expected considering estimated emission during last 50 years by hail suppression systems. To understand accumulation processes, selected water (4 surface, 3 groundwater), biota and sediment (6 surface sediments cores from Campillo de Dueñas Lakes Used Reservoir) samples have been analysed. An essay comparing growth wheat pots with different iodide concentrations has carried out. Finally, 7 tissues two sheep that graze areas both without systems 6–8 were Our results show after emissions to atmosphere, waters lowlands, including some wetlands high ecological value, not significant. Sediment did any peaks associated emission. We propose constant absorption plants could explain low concentration sediments. Crops grass accumulate excess silver, as are able absorb significant amounts silver. These bio - processes helped avoid a progressive environmental deterioration Lake. However, this hypothesis should be corroborated quantified further research on analysis natural agricultural under influence
