[Toxic effects of nitrosamines with respect to marine organisms].

Abstract

Nitrosamins present in the aquatic medium are considered as carcinogenic substances to the laboratory animals. This experimentation has for object to precise toxicity effects of the nitroso-compounds: nitrosodimethyllamine (NDMA) on two phytoplankton cultures, and on the common mussels. The addition of NDMA to the seawater of aquarium, in particular experimental conditions induces toxicity effects on the growth and behavior of phytoplanktonic cultures and of the common mussels: Mytilus edulis (tissus modification, and attack of some organs).
