Fig. 3. Thiol levels in Geukensia demissa gills (black columns) and Mytilus edulis gills (grey columns). Gills were exposed to 100 µmol l^-1 Na₂S at time zero for 10 min. Thiols pertaining to the left y-axis are cysteine (CYS), glutathione (GLU) and thiosulfate (THIO). Thiols pertaining to the right y-axis are sulfite (ST) and sulfide (SD). Values are means ± S.D. (N=3–6). Asterisks designate significant difference between mussel species (paired t-test). (A) Gills exposed to 0.5 µmol l^-1 5-HT. (B) Gills exposed to 10 µmol l^-1 5-HT.
