HC Deb 20 November 1959 vol 613 c170W
Mr. Eden

asked the Minister of Health what evidence he has of the harmful effects on human health of the accumulation in the body of small quantities of arsenical and other poisonous agricultural sprays.

Mr. Walker-Smith

There has been no substantiated evidence that current methods of using sprays containing cumulative poisons in this country are likely to produce serious chronic effects on health but the position is being kept under review.
