这项研究的目的是调查研究土壤中的锌含量；评价地统计学在描述土壤中锌的空间变异性方面的有效性；评估土壤中锌的生物有效形态和评估土壤锌的结合能力；以及估计土壤中锌的潜在生态风险。这项研究是在波兰南部的马尔波尔斯卡省进行的。该区地质构造多样，土地利用类型多样，工业发展强度大。锌含量受土壤因子和土地利用类型(耕地、草地、森林、荒地)的影响。对320个土壤样品的理化性质(质地、pH、有机C含量、全锌和有效锌含量)进行了表征。在此基础上，采用潜在生态风险指数和危害商两种方法对锌的生态风险进行了评价。土壤全锌含量变化范围为8.2 7~72 2 1 mg/kg−1D.M.根据表层半方差函数，土壤中锌的变异性从西北向东南最大。锌污染的点源位于该地区的西北部，靠近涉及锌和铅矿石加工的矿冶活动。这些发现被半方差函数曲面和双变量Moran相关系数的排列所证实。生物有效态锌的含量在0.05~46.19万mg/kg−1D.M.(0.01mmol.dm−3CaCl2)和0.03至71.54mg.kg−1D.M.(1mol·dm-−_3NH_4NO_3)。森林土壤中锌的溶解度最高，其次是耕地、草地和荒地。主成分分析表明，有机碳是控制土壤中锌的生物有效性的关键因素。69%的土壤表现出极高和中等程度的锌积累。锌对研究区生物没有生态风险，90%的土壤中锌对生态受体没有潜在的负面影响。
The aims of this study were to investigate zinc content in the studied soils; evaluate the efficiency of geostatistics in presenting spatial variability of zinc in the soils; assess bioavailable forms of zinc in the soils and to assess soil–zinc binding ability; and to estimate the potential ecological risk of zinc in soils. The study was conducted in southern Poland, in the Malopolska Province. This area is characterized by a great diversity of geological structures and types of land use and intensity of industrial development. The zinc content was affected by soil factors, and the type of land use (arable lands, grasslands, forests, wastelands). A total of 320 soil samples were characterized in terms of physicochemical properties (texture, pH, organic C content, total and available Zn content). Based on the obtained data, assessment of the ecological risk of zinc was conducted using two methods: potential ecological risk index and hazard quotient. Total Zn content in the soils ranged from 8.27 to 7221 mg kg−1 d.m. Based on the surface semivariograms, the highest variability of zinc in the soils was observed from northwest to southeast. The point sources of Zn contamination were located in the northwestern part of the area, near the mining–metallurgical activity involving processing of zinc and lead ores. These findings were confirmed by the arrangement of semivariogram surfaces and bivariate Moran’s correlation coefficients. The content of bioavailable forms of zinc was between 0.05 and 46.19 mg kg−1 d.m. (0.01 mol dm−3 CaCl2), and between 0.03 and 71.54 mg kg−1 d.m. (1 mol dm−3 NH4NO3). Forest soils had the highest zinc solubility, followed by arable land, grassland and wasteland. PCA showed that organic C was the key factor to control bioavailability of zinc in the soils. The extreme, very high and medium zinc accumulation was found in 69% of studied soils. There is no ecological risk of zinc to living organisms in the study area, and in 90% of the soils there were no potentially negative effects of zinc to ecological receptors.
