Metal concentrations in soil, soil solution, grass, earth worm and batch tests (ISO 11268-2) from a field trial with contaminated soil, biochar and peat
The dataset contains data from a field trial in which soil contaminated with metals and PAHs was stabilised with biochar and peat. The aim was to reduce the solubility and availability of the contaminants while improving soil quality. The trial and analyses are described in more detail in an open access publication in Environments: https://doi.org/10.3390/environments12110447 The data reported here are concentrations of metals, other elements, organic carbon, pH and CEC in soil; concentrations of metals, other elemetns and dissolved organic carbon as well as pH in the soil solution and eluate from leaching tests (batch tests); metal concentrations in grass (Lolium Perenne) and earthworms (Eisenia fetida).

The removal of water or any soluble constituents from the soil. Leaching often occurs with soil constituents such as nitrate fertilizers with the result that nitrates end up in potable waters.
A hard grey metallic element that takes a high polish, occurring principally in chromite: used in steel alloys and electroplating to increase hardness and corrosion-resistance.
Soil which because of its previous or current use has substances under, on or in it which, depending upon their concentration and/or quantity, may represent a direct potential or indirect hazard to man or to the environment.
A chemical element; one of the most important nonferrous metals; a ductile and malleable metal found in various ores and used in industry, engineering, and the arts in both pure and alloyed form.
Any of numerous oligochaete worms of the genera Lumbricus, Allolobophora, Eisenia, etc., which burrow in the soil and help aerate and break up the ground.
Experiment carried out on a substance or on an organism in the open air as opposed to in a laboratory.
A heavy toxic bluish-white metallic element that is highly malleable; occurs principally as galena and is used in alloys, accumulators, cable sheaths, paints, and as a radiation shield.
A heavy silvery-white toxic liquid metallic element occurring principally in cinnabar: used in thermometers, barometers, mercury-vapour lamps, and dental amalgams.
An opaque crystalline material usually of high strength with good electrical and thermal conductivities, ductility and reflectivity.
A toxic metalloid element, existing in several allotropic forms, that occurs principally in realgar and orpiment and as the free element. It is used in transistors, lead-based alloys, and high temperature brasses.
Unconsolidated soil material consisting largely of undecomposed or slightly decomposed organic matter accumulated under conditions of excessive moisture.
A soft silvery-white metallic element of the alkaline earth group. It is used in bearing alloys and compounds are used as pigments.
A brittle bluish-white metallic element that becomes coated with a corrosion-resistant layer in moist air and occurs chiefly in sphalerite and smithsonite. It is a constituent of several alloys, especially brass and nickel-silver, and is used in die-casting, galvanizing metals, and in battery electrodes.
