Description
Abstract
Neonate (<24h) larvae of the seabream,
Sparus aurata, were exposed to sublethal concentrations
(0.1-1.0 mg·L-1) of the anionic surfactant Linear Alkylbenzene
Sulphonate (LAS) for 72h under laboratory
conditions. The first histopathological changes, such as
peri-yolk sac edema, were observed at concentrations of
0.2 mg·L-1. Higher exposure concentrations provoked
disorganisation of the nervous system, trunk musculature
and trophoblastic sincitium as well as in the digestive
epithelium. Immunohystochemical CYP1A analysis,
however, was not shown to be an adequate indicator of
sublethal effects produced by exposure to this type of
anionic surfactant.
