Effects of Temperature and Glyphosate on Fatty Acid Composition, Antioxidant Capacity, and Lipid Peroxidation in the Gastropod Lymneae sp.

Little is known about the potential effects of glyphosate on freshwater gastropods and possible interactions between other stressors. A two-way factorial experiment was conducted to investigate temperature (20 °C/25 °C) (0 µg/L/200 µg/L) Lymnaea sp. After 21 days, antioxidant capacity (superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) glutathione-S-transferase (GST)), malondialdehyde content (MDA), fatty acid (FA) composition tissue were measured. Temperature had an effect SOD activity GPx activity. In contrast, increase in GST observed glyphosate-exposed snails, highlighting role detoxification process. Differences did not affect lipid peroxidation (MDA); however, we a trend suggesting presence higher MDA snails at 20 °C. The FA groups generally strongly affected by treatments, except for omega−9 (n-9) that markedly lower temperature. Changes also individual as response and/or For example, significant decrease 18:1n9 25 Our results showed profiles mainly temperature, while seemed have lesser impact.
