HC Deb 18 November 1971 vol 826 c215W
Mr. Laurance Reed

asked the Minister of Agriculture, Fisheries and Food whether his Department has succeeded in tracing the ship which dumped cyanuric chloride drums off the Kent coast; and if he will make a statement.

Mr. Anthony Stodart

No: nor have we been able to establish whether these drums were dumped or simply lost overboard. Cyanuric chloride is not highly poisonous to human beings, although it can cause irritation to the skin when in concentrated forms. It is used, among other purposes, for sterilising water in swimming pools. It is, however, toxic to fish, although it is quickly made harmless when mixed with sea water.
