title: Toxicity to fish of two organic reactor coolants.
abstract: The use of terphenyl compounds to cool nuclear reactors prompted an enquiry into the effect of these substances in the aquatic environment, should they be accidentally released.Santowax OM + 30% high boilers and HB-40 are two terphenyl compounds under study as nuclear reactor coolants at Whiteshell Nuclear Research Establishment. The acute toxicity of these two coolants to rainbow trout fry has been investigated, and it was found that Santowax OM was the more toxic. The behaviour of fish exposed to suspensions of Santowax OM in water is briefly described.
