A method was developed for the simultaneous determination of the individual toxic effects of mercuric chloride (HgCl(2)) on the respiratory and photosynthetic activities and oxidative stress in the freshwater snail Helix pomatia. Exposure of snails to various doses of HgCl(2) (0.1, 0.3 and 1.0 mg L(-1)) significantly inhibited the oxygen consumption rate. However, it was completely restored by adding an antioxidant (vitamin E) and an oxidant (phenazine methosulphate) to the assay medium. Likewise, the concentration of glutathione (GSH) was significantly lowered in a concentration-dependent manner. The reduced-nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity in the mitochondrial and microsomal fractions of hepatopancreas, as well as superoxide anion (O(2)(-)), and hydroxyl radical (HO*) production were also decreased in the presence of HgCl(2). We also found that the concentrations of lipid peroxidation products (malondialdehyde (MDA), 4-hydroxynonenal (4-HNE)) and activities of antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione-S-transferase (GST)) were significantly changed at 1.0 mg L(-1) HgCl(2). Taken together, these results indicated that HgCl(2) could cause oxidative stress in the digestive glands and antioxidant activity in snails. Tests for iframe embedding
