Détails de l’évaluation des risques
Méthode et points à examiner
Soybean is a domesticated species, highly dependent from the human species for its survival and, therefore, there are no scientific reasons to foresee survival of plants derived from lineage A2704-12  outside farming environments;
• Soybean is an exotic species, with no sexually compatible sylvan  kindred in Brazil and crossed pollination with wild species in the natural environment may not occur in the Brazilian territory;
• Molecular analysis of A2704-12 soybean evidenced that  integrity and stability of the insert was maintained;
• Analyses of segregation and genetic inheritance pattern are stable along successive generations;
• Agronomic and efficacy assessments of A2704-12 soybean indicate that the insertion failed to lead to expression of any other characteristics than expected, namely tolerance to herbicide ammonium gluphosinate (AG), and that the GMP has the same agronomic and adaptability behavior than the conventional lineage, with no change of the characters that regulate the species survival and reproduction;
• Herbicide gluphosinate is rapidly degraded in soil by action of microorganisms that use this molecule as a nitrogen source, liberating CO2 and phosphorus;
• AG is a synthetic compound corresponding to phosphinothricin, produced in nature by some soil microorganisms;
• Protein PAT has homology to no allergenic or toxic protein;
• Protein PAT fails to display significant risk for human and animal health and to the environment according to oral acute toxicity and in vitro digestibility studies;
• Foodstuffs based on soybean derived from Event A2704-12 have compositional/nutritional equivalence to products originating from non-modified soybean varieties;
• Environmental safety aspects were analyzed in local field studies where it was shown that the lineage coming from Event A2704-12 does not negatively affect survival of other plants and animals.
