Other adverse effects
· General notes:
Water hazard class 2 (Self-assessment): hazardous for water
Do not allow the product to reach groundwater, a watercourse, or a sewage system.
Must not reach bodies of water or drainage ditches undiluted or unneutralized.
Danger to drinking water if even small quantities leak into the ground.
Also poisonous for fish and plankton in water bodies.
Very toxic for aquatic organisms
Rinsing off bigger amounts into drains or the aquatic environment may lead to increased pH-values. A high pH value harms aquatic organisms. In the dilution of the use-level, the pH value is considerably reduced so that after the use of the product, the aqueous waste, emptied into drains, is only low-water dangerous.
