Multigeneration toxicity of imidacloprid and thiacloprid to Folsomia candida
In a recent study, we showed that the springtail Folsomia candida was quite sensitive the neonicotinoid insecticides imidacloprid and thiacloprid. This study aimed at determining the toxicity of both compounds to F. candida following exposure over three generations, in natural LUFA 2.2 standard soil. In the first generation, imidacloprid was more toxic than thiacloprid, with LC50s of 0.44 and 9...
متن کاملECOTOXICITY ELEMENTS TOXICITY TO TERRESTRIAL ORGANISMS Soil invertebrates: Folsomia candida, Aporrectodea caliginosa
Remarks: Neat Na-LAS was 16.1 % (w/w) active C11.6 LAS in an aqueous solution, average molecular weight = 342 g/mol; Ca-LAS was > 99 % active C11.6 LAS (crystalline), average molecular weight = 674 g/mol (Ca is bivalent and therefore, each Ca atom has 2 LAS molecules); Mg-LAS 94 % active C11.6 LAS (crystalline), average molecular weight = 658 g/mol (Mg is bivalent and therefore, each Mg atom ha...
متن کاملQSAR development and bioavailability determination: the toxicity of chloroanilines to the soil dwelling springtail Folsomia candida.
Quantitative structure-activity relationships (QSARs) are an established tool in environmental risk assessment and a valuable alternative to the exhaustive use of test animals under REACH. In this study a QSAR was developed for the toxicity of a series of six chloroanilines to the soil-dwelling collembolan Folsomia candida in standardized natural LUFA2.2 soil. Toxicity endpoints incorporated in...
متن کاملThe effect of counterion and percolation on the toxicity of lead for the springtail Folsomia candida in soil.
In standard soil toxicity tests, heavy metals are amended as water-soluble salts. The role of the counterion in metal salt toxicity is scarcely looked into. In this study, we assessed the contribution of nitrate and chloride to the toxicity of lead to Folsomia candida in a natural standard soil. Both lead salts were tested according the standard test protocol as well as after percolation of the...
متن کاملWater-extractability, free ion activity, and pH explain cadmium sorption and toxicity to Folsomia candida (Collembola) in seven soil-pH combinations.
Toxicity of cadmium to Folsomia candida was determined in soils at different pHs (3.5, 5.0, and 6.5). The Langmuir sorption constant (K(L)), based on pore-water or water-extractable concentrations, showed a pH-related increase of cadmium sorption that was most pronounced when using free Cd2+ ion activities ([Cd2+]s). Two-species Langmuir isotherms that used total cadmium concentration ([Cd]) or...
