HL Deb 29 October 1981 vol 424 c1190WA
Lord Melchett

asked Her Majesty's Government:

Whether they will state the quantities and types of persistent organo-chlorines imported into the United Kingdom in each year from 1970 to 1980.

Lord Trefgarne

I regret that this information is not available: the statistics of overseas trade do not in general distinguish organo-chlorines as a group or organo-chlorine insecticides in particular from other halogenated derivatives of hydrocarbons.
