Title: ACID-TOLERANT COLLEMBOLA CANNOT COLONIZE METAL-POLLUTED SOILS AT NEUTRAL PH

Colonization 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...

Comparative ecotoxicity of three polluted industrial soils for the Collembola Folsomia candida.

We tried to quantify the ecotoxicity of three industrial soil samples contaminated by different metals, using the Collembolan Folsomia candida as a biological model and mortality, growth and reproduction as parameters. The observed ecotoxicities are rather normal for the first such soil sample (aluminum factory) but are high for the second sample (ore treatment) and relatively low for the third...

Phytoextraction of heavy metal polluted soils using Sedum plumbizincicola inoculated with metal mobilizing Phyllobacterium myrsinacearum RC6b.

The aim of this study was to investigate the effects of metal mobilizing plant-growth beneficial bacterium Phyllobacterium myrsinacearum RC6b on plant growth and Cd, Zn and Pb uptake by Sedum plumbizincicola under laboratory conditions. Among a collection of metal-resistant bacteria, P. myrsinacearum RC6b was specifically chosen as a most favorable metal mobilizer based on its capability of mob...
