11. Toxicological information |
Acute toxicity |
LC50 (inhalation, rat): 1.28 mg/l /4 h |
Subacute to chronic toxicity |
An embryotoxic effect need not be feared when the threshold limit value is observed. |
Further toxicological information |
After inhalation: severe mucosal irritations Inhalation may lead to the formation of oedemas in the respiratory tract. After skin contact: Severe irritations. After eye contact: Burns. Risk of blindness! Other notes: Good warning effect due to low odour threshold. A risk occurs generally only after the tolerability limit is exceeded. |
Further data |
The product should be handled with the care usual when dealing with chemicals. |
12. Ecological information |
Ecotoxic effects: Biological effects: High aquatic toxicity. Harmful effect due to pH shift. Forms toxic mixtures in water, dilution measures notwithstanding. Further ecologic data: The following applies to ammonium ions in general: biological effects: fish: toxic as from 0.3 mg/l ; nourishment for fish: toxic as from 0.3 mg/l . 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. |
