| 11. Toxicological information |
| Acute toxicity |
|
LD50 (oral, rat): 2300 mg/kg LD50 (dermal, rabbit): 1500 mg/kg The literature data available to us do not conform with the labelling prescribed by the EC. The EC has dossiers of the manufacturers which have not been published. |
| Subacute to chronic toxicity |
|
The carcinogenic potential requires further clarification. An embryotoxic effect need not be feared when the threshold limit value is observed. |
| Further toxicological information |
|
After inhalation: Irritations of the mucous membranes, coughing, and dyspnoea. After skin contact: Irritations. After eye contact: Irritations. After swallowing: irritations of mucous membranes in the mouth, pharynx, oesophagus and gastrointestinal tract. No description of any further symptoms is avaiable. |
| Further data |
| The product should be handled with the care usual when dealing with chemicals. |
| 12. Ecological information |
|
Ecotoxic effects: Fish toxicity: L.idus LC50: 205 mg/l /48 h Further ecologic data: No ecological problems are to be expected when the product is handled and used with due care and attention. |
| 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: |
