Abstract

Argentinean Humid Pampa topsoil samples from sites with different land use patterns were analysed. Texture was dominated by fines (silt+clay > 50%) with high total organic carbon content (2.8 ± 1.8%), particularly in finer soils (3.7-9.9% to 0.99% in sandy soils). Carbon:nitrogen relationship was relatively homogeneous (13.9 ± 3.6%) pointing to a dominant contribution of terrestrial plant detritus. Heavy metal concentrations were low (Fe: 1.77 ± 0.50%; Mn: 446 ± 171; Zn: 48.4 ± 19.5; Cu: 17.6 ± 6.0; Pb: 10.0 ± 4.8; Cr: 7.2 ± 1.8; Ni: 6.1 ± 1.7; Cd: 0.05 ± 0.03 µg g-1) and spatially homogeneous ( 0.05). Heavy metal enrichment factors were low (0.07-2.28) indicating a natural origin.

阿根廷最高产的湿润潘帕土壤中的重金属含量

对来自不同土地利用模式的阿根廷Humid Pampa表层土样本进行了分析。质地以细粒（淤泥+粘土>50%）为主，总有机碳含量高（2.8±1.8%），尤其是在较细的土壤中（沙质土壤中为3.7-9.9%-0.99%）。碳与氮的关系相对均匀（13.9±3.6%），表明陆地植物碎屑占主导地位。重金属浓度低（Fe:1.77±0.50%；Mn:446±171；Zn:48.4±19.5；Cu:17.6±6.0；Pb:10.0±4.8；Cr:7.2±1.8；Ni:6.1±1.7；Cd:0.05±0.03µg g-1）且空间均匀（0.05）。重金属富集因子低（0.07-2.28），表明其为自然来源。
