Photos from the examined stream sections from November 2010, after an industrial disaster (Red Sludge Disaster, Hungary) (IMAGE)
Caption
A ten-year-long examination of macroinvertebrate community recovery was conducted following a catastrophic spill of highly alkaline red sludge (pH >13) into lowland streams.
T1: The section of the Torna-stream closest to the pollution. The picture was taken after the cleaning of the riverbed, the gully and the surrounding areas, as the remaining red sludge in this area was about 50-100 cm high.
T2: Torna-stream further away from the pollution. In this section only the lower parts of the bank was cleaned up.
M1: River Marcal after the Torna-stream inlet. This section was cleaned after the picture was taken.
M2: The section of the River Marcal furthest from the pollution. In this section, there was no sedimentation on the bank, and a thin coating of sediment had formed in the bed and on the vegetation.
