description: The data set contain chemical analyses of element concentrations in CaCl2-extracts of spiked soils and contaminated soils. The data is a part of the published study: Combining a Stand-ardized Batch Test with the Biotic Ligand Model to Predict Copper and Zinc Ecotoxicity in Soils. One set of 22 uncontaminated soils (soil 1-22 see Table Data SND BLMprojekt.xls) were spiked with Cu2+ or Zn2+ salts. Another set of soils from four different sites, the validation soils (soil 23–26 see Table Data SND BLMprojekt.xls), were field-contaminated. All soils were extracted with 0.001 M CaCl2 in batch tests. Soil samples (soil 1-22) were preincubated for 1 week at 20 °C at a mois-ture content equivalent to 70% of field capacity (pF 2.0) before spiking. Uncontaminated soils (soil 23-26) were then spiked to 10, 30, 100, 300, 1000, and 3000 mg Cu or Zn kg−1 dry soil, with CuCl2 or ZnCl2. Two soils were spiked with only five different concentrations because of limited amounts of available soil material, and two soils were spiked with an addi-tional dose of 6000 mg kg−1 dry weight. In total, 21 soils were spiked with Cu and 17 soils with Zn. Finally, deionized water was added to the spike solution to adjust the soil moisture content to pF 2.0. Spiked soils were subsequently equilibrated for 1 week at 20 °C before the batch test. Spike solutions were analyzed to confirm the added doses. Soil samples were equilibrated with 0.001 M CaCl2 at a liquid-to-solid ratio of 10 according to ISO 21268-2. Samples (5 g dry wt with 50 ml solution) were equilibrated for 24 ± 0.5 h in acid-washed polycarbonate vials at 10 rpm in an end-over-end shaker and then centrifuged at 4000 g for 15 min. The pH was measured on a portion of the eluate, and the rest was filtered through a 0.45-µm filter before analysis of Cu, Zn, Ca, Na, K, Mg, Fe, Al, and dissolved organic carbon (DOC). Samples for elemental anal-ysis were acidified with 5 µL ml−1 suprapure HNO3 before analysis with inductively coupled plasma (ICP…
description: Datasetet innehåller kemiska analysresultat av elementkoncentrationer i CaCl2-extrakt av spikade jordar och förorenade jordar. Setet är en del av den data som ligger till grund för studien: Combining a Standardized Batch Test with the Biotic Ligand Model to Predict Copper and Zinc Ecotoxicity in Soils. En uppsättning av 22 oförorenade jordar (jord 1-22 se Data SND BLMprojekt.xls) spikades med Cu2+ eller Zn2+-salter. En annan uppsättning jordar från fyra olika platser, valideringsjordarna (jord 23–26 se tabell Data SND BLMprojekt.xls), var förorenade. Alla jordar extraherades med 0,001 M CaCl2 i batchtester. Jordprover (jord 1-22) inkuberades under 1 vecka vid 20°C vid en fukthalt motsvarande 70 % av fältkapaciteten (pF 2,0) före spikning. Oförorenade jordar (jord 23-26) spikades med 10, 30, 100, 300, 1000 och 3000 mg Cu eller Zn kg−1 torr jord, med CuCl2 eller ZnCl2. Två jordar spikades med endast fem olika koncentrationer på grund av begränsade mängder tillgängligt jordmaterial, och två jordar spikades med en extra dos på 6000 mg kg−1 torrvikt. Totalt spikades 21 jordar med Cu och 17 jordar med Zn. Slutligen tillsattes avjoniserat vatten till spikningslösningen för att justera markfukthalten till pF 2,0. Spikade jordar jämviktades därefter under 1 vecka vid 20°C före batchtestet. Spikningslösningar analyserades för att bekräfta de tillsatta doserna. Jordproverna jämviktades med 0,001 M CaCl2 vid L/S 10 enligt ISO 21268-2. Prover (5 g torr vikt med 50 ml lösning) jämviktades under 24 ± 0,5 h i syratvättade polykarbonatflaskor vid 10 rpm i en end-over-end skakapparat och centri-fugerades sedan vid 4000 g i 15 min. pH mättes på en del av eluatet och resten filtrerades genom ett 0,45 µm filter innan analys av Cu, Zn, Ca, Na, K, Mg, Fe, Al och löst organiskt kol (DOC). Prover för elementaranalys surgjordes med 5 µL ml−1 suprapure HNO3 före analys med induktivt kopplad plasma (ICP) sektorfältmasspektrometri (Element1; Thermo Fisher) eller ICP atomemiss-ionsspektroskopi (… @sv
