Short-term toxicity to fish
Administrative data
- Endpoint:
- short-term toxicity to fish
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 2010
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The study is performed according to GLP.
- Justification for type of information:
- Hypothesis for readacross:
The main component of the target substance “Reaction product of lead chloride or lead sulphate with alkaline solution” is lead (Pb). Pb salts used as
source material are waste materials produced by Pb battery recycling process or byproducts of the hydrometallurgical upgrading of PGM rich lead bullion. Therefore, available data
from Pb compounds was used for readacross.
The test substance is waste material from lead battery reprocessing, which is similar to the target substance and therefore considered applicable for readacross.

Sampling and analysis
- Analytical monitoring:
- no
- Details on sampling:
- Due to the sparingly soluble properties of the test item, the study was performed with the "WAF" ("water accommodated fraction") (OECD Series on Testing and Assessment Number 23: "Guidance Document on Aquatic Toxicity of Difficult Substances and Mixtures" and OECD Series on Testing and Assessment Number 29: "Guidance Document on Transformation/Dissolution of Metals and Metal
Compounds in Aqueous Media). Stirring time was fixed to 24 hours followed by a sedimentation period of 1 hour.
Test organisms
- Test organisms (species):
- Danio rerio (previous name: Brachydanio rerio)
- Details on test organisms:
- Zebra danio fish (Brachydanio rerio) were used as test animals. The test fish were healthy and showed no abnormal appearance. They had a total length of 3 cm (+/1
cm). The fish were held in the
Hydrotox laboratory since July 8th, 2010. The fish were purchased by Aquarium Dietzenbach Fischzucht, vanHevesy
Str. 1 a, D63128

- Details on results:
- Justification for readacross:
Lead (Pb) is the main component of the target substance, and considered the major driver for adverse effects based on its properties and relative quantity in the substance. For
toxicity assessment the bioavailable part is relevant. From the target substance itself, Pb is poorly water soluble. Solubility of Pb from the test substance was same order of magnitude as for the target
substance. Therefore, it is considered that the used readacross
data gives a good estimate on the adverse effects of the target substance.
