“…F. candida Willem 1902 is a common Collembola species that is present in soils all over the world and has been used for ecotoxicological testing in numerous publications [27][28][29][30][31][32][33][34]. Series of tests are conducted to examine mortality, reproduction, bioaccumulation, and effects on the behavior of F. candida to evaluate the toxicity of organic and inorganic contaminants.…”

Background Toxicity of silver nanoparticles (AgNP) has been studied frequently due to a rise in application in various products. Various studies on AgNP toxicity with terrestrial and aquatic organisms confirmed their negative effects. In our previous experiments, strong variability was observed in the reproduction of Collembola (Folsomia candida) in different repeats. To investigate the effects of silver on the reproduction of Folsomia candida, they were exposed in laboratory-controlled conditions to AgNP and silver nitrate (AgNO3) at a concentration of 30 mg/kg dry soil for 28 days and compared to controlled individuals not exposed to silver. We repeated reproduction tests on the toxicity of silver to Folsomia candida four times throughout one year (April, July, October and January) in order to explore the temporal variability of their outcome. Results While adult survival was similar in all treatments and seasons, reproduction in the control increased from April to October. Significantly lower reproduction was found in January with only 385–424 juveniles per vessel, compared to 504–633 individuals in other months. Strong toxic effects of both silver treatments were observed in July, April and October. However, AgNP showed no toxic effects on the reproduction of F. candida in January. The relative toxicity of both substances varied between single experiments: AgNP were more toxic than AgNO3 in April and July, and less toxic in October and January. Conclusion These findings indicate that the reproduction of F. candida in the control had a significant effect on the results of the toxicology experiments. Moreover, we demonstrated the reproductive toxicity of AgNP in soil at a much lower concentration than reported thus far. Therefore, to guarantee reliability and reproducibility, we recommend to disregard any test results where the reproduction rate of F. candida in the control is significantly different from the average in the respective laboratory, even if the validity criteria of the test are met.

“…Veterinary pharmaceuticals are also the focus of different studies using terrestrial invertebrates. A battery of pharmaceuticals (ivermectin, fipronil, fluazuron, and closantel) has been evaluated using F. candida in tropical Brazilian soils [153]. The results confirmed higher chronic toxicity of fipronil (EC 50 0.19 mg kg À1 d.w.) and ivermectin (EC 50 0.43 mg kg À1 d.w.), followed by fluazuron (EC 50 3.07 mg kg À1 d.w.).…”

“…Each experimental treatment was performed in 6 replicates, and in each plastic container with volume by 110 mL was added 25 g from experimental treatment and ten collembolans aged 10-12 days [32]. The toxicity test was performed according to the method described in [33], for 28 days under laboratory conditions at a temperature of 20-22°C in the dark.…”

Organic wastes treated, used on agricultural land, can replace inorganic fertilizers, due to physical and chemical properties that improve soil and crop quality on long-term. In this study, was used biochar produced from sewage sludge, compost obtained from cattle manure, and mixtures made from biochar-compost in different concentration, at 5 t/ha and 30 t/ha, application rates. The aim of the study is to determine the influence of this organic wastes on the heavy metals bioavailability in greenhouse conditions and on Folsomia candida and Eisenia Andrei, used as test organisms under laboratory conditions. Compared to control variants, the use of biochar mixed with compost in different concentration at 5 t/ha and 30 t/ha, application rates, in a greenhouse experiment did not significantly affect the concentrations of heavy metals (Cu, Cd, Zn and Pb). Reproduction of collembolans has not been influenced by increasing application rate of the mixtures, and by concentrations of biochar or compost. The earthworms recorded weight losses, only in the experimental treatments with sewage sludge biochar used in different concentrations, at both application rates.
