The possible effects of the use of domestic detergents containing LAS (Linear-alkyl -benzene-sulphonate) in the gills of Mytilus sp., in presence and absence of cadmium., are investigated. Preliminary analyses were carried out to determine the trend of LAS concentration with time in the aquaria containing mussels. The experimental conditions were: 6 mg/lLAS; 5o μ/lCd; 6 mg/l LAS + 5oμ/lCd;.After 15 and 30 day exposure ten mussels were sacrified and their gills observed by Scanning Electron Microscope (SEM). Another group of ten mussels was sacrified and used for Atomic Absorption Spectrophotometry analysis of Cd accumulation. SEM investigations after 30 days showed that gill lamellae were severely damaged by LAS and LAS + Cd.Cadmium alone does not cause any damage, which can be seen by SEM.
