Characteristics of the contaminated soil used for soil dust application.
| Location | Litavka (49° 43′ N, 14° 0′ E) |
|---|---|
| Soil type and subtype | Gleyic fluvisol |
| Soil texture | Clay loamy sand |
| pH (–) | 5.3 |
| CEC (mmol(+)/kg) | 57 ± 4 |
| Corg (%) | 1.8 |
| Astotal (mg/kg)/Asws (mg/kg) | 286 ± 14/1 ± 0.2 |
| Cdtotal (mg/kg)/Cdws (mg/kg) | 37 ± 0.8/0.2 ± 0.02 |
| Pbtotal (mg/kg)/Pbws (mg/kg) | 2344 ± 57/5 ± 1 |
| Zntotal (mg/kg)/Znws (mg/kg) | 3515 ± 54/16 ± 1 |
CEC is the cation exchange capacity, Corg is organic carbon, (As, Cd, Pb or Zn)total is the pseudototal content of elements determined by ICP–MS (extraction by aqua regia), and (As, Cd, Pb or Zn)ws is the water-soluble content of elements determined by ICP–OES (24-h extraction by demineralized water, 1:5 w/v). Czech legislation limits for pseudototal contents of elements in light-textured soils (mg/kg): As—15, Cd—0.4, Pb—55 and Zn—10530.
