Pyrochlore, antimony lead yellow

GHS

General Information

Name:

Pyrochlore

Implementation:

EU

Type of classification:

self-classification

Remarks:

Pyrochlore:

The overall chemical and physiological properties of pyrochlore are principally characterised by a degree of inertness because of the specific synthetic process (calcination at high temperatures, approximately 1000°C), rendering the substance to be of a unique, stable crystalline structure in which the majority of atoms are tightly bound and not prone to dissolution in environmental and physiological media. This has been shown in in-vitro bioaccessibility testing for antimony, in which dissolved Sb concentrations were below 105 ug/L even at the highest loading of 0.1g/L, thus implying a solubility of < 0.12% of antimony. Hence, Sb can be considered as not bioavailable and is not regarded concerning toxicological and environmental effects.

On the other hand, lead dissolution levels were much higher (up to 6.2 mg/L at pH 1.7) and therefore have to be regarded concerning toxicological and environmental aspects. Substance-specific data on the toxicity of pyrochlore is only partly available, so that read-across to lead oxide and sparingly soluble lead compounds was conducted in order to complete the data set.

It is explicitely noted here that due to the outcome of an acute toxicity study according to OECD 401, classification as Acute Tox. 4; H302 for the pigment pyrochlore is not recommended.

Lead:

Existing classification in accordance with Commission Regulation (EC) No 1272/2008 of the European Parliament and of the Council on classification, labelling and packaging of substances and mixtures. Index No. 082-001-00-6 "lead compounds with the exception of those specified elsewhere in this Annex". The basis of the original environmental classifications is unknown.  However current industry data supports the EU environmental classifications. The basis of the original human health classifications is unknown.  However the lead oxide CSR includes a self classification section that, based on industry’s analysis of current data, proposes CHANGES TO THE EU CLASSIFICATION. Industry proposes changes to the existing harmonised classification with the addition of Carc. 2 and the change of STOT RE2 to STOT RE1 that are not covered in Annex VI.

As a result, the classification for acute toxicity via the oral route and by inhalation is not supported for the pigment pyrochlore.
