Abstract:
Nowadays, transgenic soya, modified in order to withstand the impact of the herbicide glyphosate, is one of the main crops grown in Argentina. Due to the large number of commercial formulations that include this drug, is important to analyze both, the acute and chronic environmental impact that they cause. Here the acute toxicity of two commercial herbicides glyphosate based toward the fish Poecilia reticulate “guppy” was evaluated and compared with pure glyphosate solutions. Interestingly, while commercial herbicides formulations induce a 100% of mortality at concentration ranged between 50 and 100 μl/l, the pure glyphosate does not present mortality even at doses higher than 400 mg/l. When some long term effects toward Cyprinus carpio haematopterus “koi” were determined by using the sub-lethal doses already calculated it was demonstrated that one of the commercial herbicides induces severe haematological alterations.
