| 11. Toxicological information |
| Acute toxicity |
| Quantitative data on the toxicity of this product are not available. |
| Further toxicological information |
| The following applies to lead compounds in general: Due to the poor absorbability via the gastrointestinal tract, only very high doses lead to acute cases of intoxication. After a latency period of several hours, metallic taste, nausea, vomiting, and colics occur, in many instances followed by shock. Chronic uptake causes peripheral muscular weakness ("drop-wrist"), anaemia, and central-nervous disorders. The information available suggests that an embryotoxic potential must be considered probable. Women of child-bearing age should not be exposed to the substance over longer periods of time (observe critical threshold). |
| Further data |
| Further hazardous properties cannot be excluded. |
| 12. Ecological information |
|
Ecotoxic effects: The following applies to lead compounds in general: biological effects: toxic for aquatic organisms (calc. as free lead): fish: lethal from 1.4 mg/l up; S. gairdnerii: LC50: 0.14 mg/l/96h ; L. idus LC50: 546 mg/l; fish test LC50: 236 mg/l; bacteria: Ps. putida toxic from 1.8 mg/l up; algae: Sc. quadricauda toxic from 3.7 mg/l up; M. aeruginosa 0.45 mg/l; protozoa: E. sulcatum toxic from 0.02 mg/l up; U. parduczi toxic from 0.07 mg/l up; arthropods: D. magna LC50: 2.5 mg/l; hazard for drinking water. 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: |
| 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. |
| 14. Transport information |
| Not subject to transport regulations. |
| 15. Regulatory information |
