“…Samples of two Brazilian soils, Entisol and Oxisol, were collected in the municipalities of Araranguá (29º 00′S, 49° 31′W) and Palmitos (27º 04'S, 53º 09'W), respectively, from the top soil layer (0-20 cm), in areas with no history of contamination. The sampled soils were sieved (2 mm), defaunated applying the procedure described by Alves et al (2019), air-dried and kept protected from light at room temperature.…”

The aim of this study was to assess the effect of temperature on the toxicity of pronil toward earthworms (Eisenia andrei) in two Brazilian soils (Entisol and Oxisol) with contrasting textures. In the case of Entisol, the in uence of the soil moisture content on the toxicity was also investigated.Earthworms were exposed for 56 days to soils spiked with increasing concentrations of pronil under scenarios with different combinations of temperature (20, 25 and 27 ºC) and soil moisture content (60 and 30% of water holding capacity (WHC) for Entisol and 60% WHC for Oxisol). The number of juveniles produced was taken as the endpoint and a risk assessment was performed based on the hazard quotient (HQ). In Entisol, at 60% WHC the pronil toxicity decreased at 27 ºC compared with the other temperatures tested (EC 50 = 52.58, 48.48 and 110 mg kg -1 for 20, 25 and 27 ºC, respectively). In the case of Oxisol at 60% WHC, the pronil toxicity increased at 27 ºC compared with other temperatures (EC 50 = 277.57, 312.87 and 39.89 mg kg -1 at 20, 25 and 27 ºC, respectively). An increase in pronil toxicity was also observed with a decrease in soil moisture content in Entisol at 27 ºC (EC 50 = 27.95 and 110 mg kg -1 for 30% and 60% WHC, respectively). The risk of pronil was only signi cant at 27 ºC in Entisol and Oxisol with water contents of 30% and 60% WHC, respectively, revealing that higher temperatures can increase the risk of pronil toxicity toward earthworms. The results reported herein show that soil properties associated with climatic shifts could enhance the ecotoxicological effects and risk of pronil for earthworms, depending on the type of soil.

“…Closantel did not show severe effects on F. candida. Alves et al [154] reported adverse effects of fluazuron on the reproduction of E. andrei and F. candida (EC 50 20.8 mg kg À1 d.w. and 4.48 mg kg À1 d.w., respectively). The same species have been used to assess the effects of nicarbazin and monensin used in the poultry industry [155].…”

“…This is, for example, the case of F. candida against carbamazepine, using a light avoidance innovative test at very low concentrations (AC 50 0.04 mg kg À1 d.w.) [151]. Alves et al [154] found avoidance response of F. candida and E. andrei against fluazuron (AC 50 1.73 and 4.78 mg kg À1 d.w., respectively), highlighting the higher sensitivity of this behavioral response compared to reproduction (EC 50 20.8 mg kg À1 d.w.).…”

“…Soil pH (KCl) was measured for all treatments at the start and end of the ecotoxicological assays (Supplemental Table S1). The water holding capacity (WHC) of the soils was determined according to ISO 11268:2 (2012) as described in Alves et al (2019). For the ecotoxicological assays, the soil samples were sieved (2 mm) and defaunated by using three 24-h cycles of freezing and thawing to eliminate the presence of natural soil organisms.…”

Shifts in precipitation regimes due to the predicted climate changes can alter the water content in tropical soils and, consequently, may influence the toxicity of pesticides to soil fauna. This study assessed the influence of soil moisture content on the toxicity of the insecticide imidacloprid to the collembolans Folsomia candida in two tropical soils and evaluated the risk of this active ingredient for this species in the soils tested through the toxicity exposure ratio approach. Acute and chronic toxicity tests with F. candida were performed using an Entisol and an Oxisol. The soils were spiked with increasing imidacloprid concentrations while simulating normal water availability (60% of the water holding capacity [WHC]) and water restriction (30 or 45% WHC) for the tests. In the Oxisol, the reduction of soil moisture content significantly increased the toxic effects of imidacloprid on F. candida's survival (LC 50 at 45% WHC = 23.8 vs. LC 50 at 60% WHC >64 mg kg −1) and reproduction (effective concentration causing reductions in species reproduction of 50% [EC 50 ] at 45% WHC = 0.32 vs. EC 50 at 60% WHC = 2.83 mg kg −1), but in the Entisol no clear influence of the soil moisture on the toxicity of imidacloprid for collembolans was found. A significant risk for F. candida was observed in the Oxisol only when in water restriction, whereas in the Entisol it occurred regardless of soil moisture, suggesting that the imidacloprid hazard and risk for F. candida may be increased if soil moisture decreases due to climate changes, depending on the soil type.
