Table 19. In the Fisheries Laboratory, Burnham-on-Crouch, England, a device has been developed
to investigate the toxicity of oil and of oil- special 18-1 seawater experimental vessels, and shrimps (Crangon vulgaris) as experimental animals.
The percentage of dead shrimps is identified after experiments 'of 100 min in 1 ml/l of fresh
Kuwait crude oil or in a mixture of 1 ml/l oil plus 1 ml/l of the dispersant to be tested. Dispersant
concentrates are diluted to 10% for the experiment. Beach tests were done by spraying limpets
(Patella vulgata) with oil or with dispersants. An asterix means that the toxicity of the dispersant
or oil- Britain such dispersants are licensed for use only in the case of oil spills which do not increase
the toxicity which the fresh oil alone exerts (Norton and Franklin 1980)
