IANNACONE, José Alberto et al. Evaluación del riesgo ambiental de carbofurano en bioensayos con organismos no blanco. Acta toxicol. argent. [online]. 2011, vol.19, n.1, pp.19-31. ISSN 1851-3743.

Carbofuran is one of the most employed pesticides in Peruvian agriculture. This research aimed to evaluate the risk assessment in bioassays of carbofuran on eleven non-target species. The following relative sequence in decreasing ecotoxicity order in terms of RQ (Risk quotient) to carbofuran to 19 end points on 11 species was found: Daphnia magna (mortality) > Lemna minor (inhibition of new fronds) > Paracheirodon innesi (strange swim) = P. innesi (increase of opercula movement) > Chironomus calligraphus (mortality) > L. minor (necrosis) > P. innesi (mortality) > L. minor (chlorosis) > Tetrapygus niger (inhibition of fertilization)> Coturnix japonica (mortality) > Oncorhynchus mykiss (increase of coloration) > Ceraeochrysa cincta (not hatch of eggs) > O. mykiss (mortality without oxygen) > O. mykiss (mortality with oxygen) > Trichogramma pretiosum (mortality) > C. cincta (mortality) > T. pretiosum (not emergence of adults) > Trichogramma pintoi (mortality) > Beauveria bassiana (inhibition of growth). Risk quotient (RQ) indicated that carbofuran is highly risky mainly to aquatic environment than terrestrial.
