Induction of Ultrastructural Alterations in the Digestive Gland of Mytilus galloprovincialis (Lamarck) by Crude Oil
The digestive gland of mussel is the major tissue for the uptake of petroleum hydrocarbons. Our interest was to study their effects on the fine structure of epithelial cells within digestive tubules. In this view, we have performed a contamination by a crude oil.
Mytilus galloprovincialis (Lmk.), 50 to 55 mm shell lengh, were collected from the “étang de Thau” (Séte, France) and held in a system of recirculating seawater (38°/oo, 15°C). The digestive glands of mussels contamined by a six days exposure to a crude oil (Ashtart : 20 mg.1−1) adsorbed on silica (0.065–0.200 mm : 1.7 mg.1−1)were studied. The hydrocarbons contents in the digestive gland were analysed by gas chromatography (GC) and the tissues were observed in light and electron microscopy.
