Description of key information

No data is available on particle size distribution of lead telluride.

Additional information

Lead telluride will be registered as a transported intermediate with a tonnage band of 10 – 100 t/a. Based on Article 18, Chapter 3, Title II of regulation (EC) 1907/2006, any manufacturer or importer of a transported isolated intermediate in quantities of one tonne or more per year shall submit a registration to the Agency for the transported isolated intermediate. This registration shall include any available existing information on physicochemical, human health or environmental properties of the intermediate. Where a full study report is available, a study summary shall be submitted. According to “ECHA Guidance for intermediates, February 2008”, a registrant of transported isolated intermediates can provide reduced registration information according to Article 18(2) if he confirms that he is manufacturing and/or using the substance under strictly controlled conditions and if he confirms himself or states that he has received confirmation from the user that the substance is used under strictly controlled conditions as described under Article 18(4). For transported isolated intermediates the information requirements on physicochemical, human health and environmental properties are limited to the data that is available to the manufacturer (e.g. information he holds himself or that he can obtain from other sources) without any additional testing.

For lead telluride a substance specific literature search has been conducted (see IUCLID section 12). Since no relevant data is available on particle size distribution of lead telluride, no study summary is provided for this endpoint.
