“…In addition, high frequency of applications may dictate that the likelihood of pesticide mixture exposures (and hence their potential additive or synergistic effects) is also greater (e.g. Moreira et al, 2017;Vig et al, 2008). Future studies are hence needed to evaluate the effects of environmental realistic pesticide mixtures in tropical settings.…”

We have successfully applied run-off treatment and re-introduction designs for recovery potential evaluation as modifications of a synthetic microcosm test.…”

Effects of esfenvalerate on zooplankton and their recovery potential were studied using an indoor synthetic model ecosystem. Esfenvalerate was applied to the system by direct spiking to overlying water or the introduction of treated slurry soil to imitate drift and runoff exposure. Four zooplankton taxa, Daphnia magna (Cladocera), Heterocypris incongruens (Ostracoda), Cyclops sp. (Copepoda), and Brachionus calyciflorus (Rotifera), were exposed to esfenvalerate with Raphidocelis subcapitata (green alga). In a drift scenario, lower doses (0.02-0.5 µg/L) showed slight or negligible effects, but the results for the highest dose (5 µg/L) indicated direct effects, as remarkable population decreases were observed for three taxa (except rotifera). However, for the latter dose, results of weekly or single (Day-15) zooplankton re-introductions after dosing demonstrated resilient recovery. In a runoff scenario, a nominal dose of 20 µg/L, in which the measured water concentrations remained at 3-6%, had effects similar to those of the high drift exposure scenario for cladocera and ostracoda.

“…In recent years, studies have demonstrated a high toxicity of Score 250 EC® and especially Kraft 36 EC® to non-target organisms https://doi.org/10.1016/j.ecoenv.2020.110446 (Moreira et al, 2017;Nunes et al, 2016;Nunes and Espíndola, 2012;Pitombeira de Figueirêdo et al, 2019). For example, Oliveira et al (2018), evaluating their toxicity to the potworm Enchytraeus crypticus, the collembolan Folsomia candida, and the mite Hypoaspis aculeifer, concluded that environmentally relevant concentrations of both pesticides may significantly affect the reproduction of Collembola (Oliveira et al, 2018).…”
