Chemical name: Plumbane, tetramethyl-

Final regulatory action has been taken for the category: Industrial

Final regulatory action: The chemical is Banned

Use or uses prohibited by the final regulatory action:

Not applicable.

Use or uses that remain allowed:

Not applicable.

The final regulatory action was based on a risk or hazard evaluation: Yes

Summary of the final regulatory action:

Pesticides and Toxic Chemicals Control (Prohibited pesticides) Order No.4 of 2015 made under the Pesticides and Toxic Chemicals Control Act 2000 (No 13 of 2000) Prohibits importation, sale and use of Tetraethyl lead and Tetramethyl lead.

The reasons for the final regulatory action were relevant to: Human health

Summary of known hazards and risks to human health:

One significant source of human exposure to lead has been through inorganic lead compounds emitted from the combustion process as a direct result of the use of alkyl lead as an additive in gasoline. Lead emitted from the exhaust of vehicles is primarily in the form of inorganic particles (e.g. PbBrCI), with only small amounts (less than 10% of total emissions) in the form of organolead vapours (Royal Society of Canada, September 1986). The discussion on toxicological properties therefore focuses on the risks to human health associated with exposure to lead, tetraethyl lead and tetra methyl lead.

Expected effect of the final regulatory action in relation to human health:

The possibility of risks and exposure to this chemical by humans decreased.

Date of entry into force of the final regulatory action: 02/04/2015
