| 12. Ecological information |
|
Ecotoxic effects: Biological effects: Product reacts with water. After reaction, harmful effect on aquatic organisms. Fish toxicity: fish LC: > 0.1 mg/l ; Further ecologic data: The following applies to zinc and its compounds in general: Inorganic zinc salts have a bactericidal effect. From >10 mg Zn/l on, the bacteriological self-purification of water is inhibited or suppressed. Toxic for water organisms. Lethal for fish from 0.1 mg/l in soft water. Fish toxicity: LC50 (L. idus) 21 mg/l (ZnCl2); zinc ions: toxic to Daphnia magna from 0.3 mg/l. Contamination of ground water involves risks for drinking water catchment. Do not allow to enter waters, waste water, or soil! |
| 13. Disposal considerations |
| Product: |
| There are no uniform EC Regulations for the disposal of chemicals or residues. Chemical residues generally count as special waste. The disposal of the latter is regulated in the EC member countries through corresponding laws and regulations. We recommend that you contact either the authorities in charge or approved waste disposal companies which will advise you on how to dispose of special waste. |
| Packaging: |
| Disposal in compliance with official regulations. Handle contaminated packaging in the same way as the substance itself. If not officially specified differently, non-contaminated packaging may be treated like household waste or recycled. |
