We tested this hypothesis by investigating the in vivo effects of the Roundup on the testis and epididymal region of drake Anas platyrhynchos. To our knowledge this is the first study to demonstrate a systematic response by the antioxidant systems of fish to Roundup exposure. The comet assay with gill cells showed to be an important complementary tool for detecting genotoxicity, given that it revealed DNA damage in periods of exposure that erythrocytes did not.

Roundup produced a clear delay in periphytic colonization in treated mesocosms and values of the periphytic mass variables dry glifostao, ash-free dry weight and chlorophyll a were always higher in control mesocosms. Roundup Ultra is of more ecotoxicological relevance than the active ingredient, glyphosate, to Lumbriculus variegatus regarding accumulation potential and enzymatic responses.
