Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The main component of the 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 by-products of the hydrometallurgical upgrading of PGM rich lead bullion. Therefore, available data from Pb compounds was used for read-across.

For aquatic invertebrates, 21 acute toxicity data points were considered for read-across purposes. Test data (1 study) was available for Pb battery reprocessing waste, which was considered to be close to one source material of the target substance based on its production process, composition and physico-chemical properties. In addition, data was available for lead dichloride (4 studies) and lead dinitrate (16 studies). The following lowest acute toxicity values (EC50) for aquatic invertebrates were reported:

- Wastes, Pb battery reprocessing: > 100 mg/L (D. magna, pH 7.77 -7.88, hardness -)

- Lead dichloride: > 0.107 mg/L dissolved Pb (C. dubia, pH 7.94, hardness 280 -300 mg/L)

- Lead dinitrate: 0.026 mg/L dissolved Pb (C. dubia,pH 8.0 -8.2, hardness 20 -30 mg/L)

For aquatic algae, four acute toxicity data points were considered for read-across purposes. Test data (1 study) was available for Pb battery reprocessing waste, which was considered to be close to the target substance based on its composition and physico-chemical properties. In addition, data was available for lead dichloride (1 study) and lead dinitrate (2 studies). The following lowest acute toxicity values (EC10) were reported:

- Wastes, Pb battery reprocessing: 0.36 mg/L (D. subspicatus, pH and hardness not reported)

- Lead dichloride: 0.005 mg/L dissolved Pb (P. subcapitata, pH 7.28, hardness 24 mg/L)

- Lead dinitrate: 0.029 mg/L dissolved Pb (S. costatum,pH 8.1, hardness -)

Use of the substance will be as an intermediate under strictly controlled conditions. Therefore, further evaluation of ecotoxicological information has not been conducted at this stage.

Conclusion on classification

Environmental self-classification was based on the mixture rules. All relevant constituents having environmental hazard entries were taking into account, and the maximum concentrations of these constituents were considered when applying the classification and labelling of this target substance (for further details see separate report in IUCLID Section 13). The environmentally hazardous constituents of this UVCB-substance are only slighly water soluble or non-soluble (section 4). However, the consertative approach was considered to order to derive this classification assuming that all constituents are completely dissolved (tier 1: classification based on elemental and mineralogical data).

Aquatic acute toxicity:

This substance is classified as Aquatic Acute Cat.1; H400 according to CLP reg..

Aquatic Chronic toxity:

CLP:

Hazardous to aquatic environment Chronic Cat. 1; H410
