§ Mr. Ernie Rossasked the Secretary of State for the Environment if it is his intention to set safety limits for the amount of ethylene dibromide in the atmosphere in connection with grain fumigation and anti-knock petrol additives.
§ Mr. WaldegraveNo. Ethylene dibromide is not used for grain fumigation in the United Kingdom, and the kerbside concentrations arising from its use in petrol are far below those which might give rise to concern. Its use in petrol will decrease in line with the reduction of lead.
