Toxicity of Pb and of Pb/Cd combination on the springtail Folsomia candida in natural soils: reproduction, growth and bioaccumulation as indicators.
The toxicity of Pb and Cd+Pb was assessed on the Collembola F. candida in two cultivated soils (SV and AU) with low organic matter (OM) content and circumneutral to basic pH, and an acid forested soil (EPC) with high OM content. Collembola reproduction and growth as well as metal content in Collembola body, in soil, exchangeable fraction and soil solutions, pH and DOC were investigated. Pb and ...
متن کاملColonization of heavy metal-polluted soils by Collembola: preliminary experiments in compartmented boxes
9 10 Two-week laboratory experiments were carried out in plastic boxes separated in two connected 11 compartments filled with a neutral soil (mull humus) at pH 7.7 and an acid soil (moder humus) at pH 12 4.3, containing their original faunas. Migration of Collembola from one compartment to the other was 13 allowed through a perforated wall. The mull was contaminated with three concentrations of...
متن کاملUnexpected reduction in reproduction of Collembola exposed to an arsenic-contaminated soil.
To assess the problems posed by ecological testing of the toxicity of polluted soils, we applied the Collembola reproduction test to the soil from a mining site polluted by metals. Our aim was to quantify the chronic toxicity of contaminated soil using the Folsomia candida reproduction test. Briefly, the polluted soil, which contains in particular large quantities of arsenic, is mixed in variou...
متن کاملThe influence of humic acids on the accumulation of lead (Pb) and cadmium (Cd) in tobacco leaves grown in different soils
Four types of soil (red, yellow, cinnamon, and paddy soil) from China were used to conduct experiments in pots to study the influence of humic acid (humic acid (HA) and fulvic acid (FA)) on the accumulation of lead (Pb) and cadmium (Cd) in tobacco leaves. In non-polluted soils, the tobacco leaf uptake of Cd was dramatically influenced by the total soil metal concentration and soil properties, w...
