“…The coefficient of variation (CV) value was relatively small for As, which was expected to be dominated by natural sources. The other soil heavy metals had CV values between 40.9% and 154.4%, which indicated proper variability and these elements are more likely to be affected by anthropogenic sources (Luo et al 2007). …”

Soil in metropolitan region suffers great contamination risk due to the rapid urbanization especially in developing countries. Beijing and Tianjin, together with their surrounding regions, form a mega-metropolitan region in northern China. To assess the soil environmental quality, a total of 458 surface soil samples were collected from this area. Concentrations of Cr, Cu, Pb, Zn, As, Cd, and Hg were analyzed and compared to the Chinese environmental quality standards for soil. Multivariate analysis was carried out to identify the possible sources and Geographic Information Systems techniques were applied to visualize the spatial data. It was found that the primary inputs of As were due to pedogenic sources, whereas Hg was mainly of anthropogenic source. Other elements including Cr, Cu, Pb, Zn, and Cd were from both lithogenic and anthropogenic origins. Health risk assessment based on the maximum heavy metal concentration indicated that As derived from sewage irrigation area can result in carcinogenic lifetime risk due to ingestion and/or dermal contact of soil. The potential non-carcinogenic risk for children is significant for Pb and the cumulative effect of multiple metals is of concern for children in the vicinity of mining site. The results increased our knowledge for understanding natural and anthropogenic sources as well as health risk for metals in metropolitan soil.

“…The third component includes Cd and Pb, which were also related to human activities in other works [19][20]45]. Besides this, the high contents of these metals found in some samples confirmed a point pollution source, especially for Pb.…”

“…This may be indicative of a high Cd retention by soil, probably due to the presence of organic matter. Coefficients of variation were low in general, except for available P and Pb, and thus it would be expected that they have an anthropogenic source [45].…”

“…Under the common influences of natural and anthropic input such as the utilization of chemical fertilizers and pesticides, the source of HMs in agricultural soil become more complex. Meanwhile, due to the heterogeneity of soil itself, concentrations of HMs vary remarkably over space (Luo et al 2007). Only relying on multivariate statistics or geostatistics, it is very difficult both to disclose their sources and to characterize their regional variations.…”

“…Multivariate analysis, such as factor analysis (FA) and cluster analysis (CA) has been widely used to assist the interpretation of environmental data (e.g., Tuncer et al 1993;Einax and Soldt 1999) and to distinguish between natural and anthropogenic inputs (e.g., Jobson 1991;Hopke 1992;Facchinelli et al 2001;Gallego et al 2002;Lucho-Constantino et al 2005;Zhang 2006;Luo et al 2007). Under the common influences of natural and anthropic input such as the utilization of chemical fertilizers and pesticides, the source of HMs in agricultural soil become more complex.…”

In a typical modern agricultural Zone of southeastern China, Haining City, 224 topsoil samples were collected from paddy fields to measure the total concentrations of copper (Cu), lead (Pb), zinc (Zn), cadmium (Cd), chromium (Cr), mercury (Hg), arsenic (As) and cobalt (Co). The total concentrations ranged from 15.30 to 78.40 mg kg -1 for Cu, 20.10 to 41.40 mg kg -1 for Pb, 54.98 to 224.4 mg kg -1 for Zn, 0.04 to 0.24 mg kg -1 for Cd, 54.90 to 197.1 mg kg -1 for Cr, 0.03 to 0.61 mg kg -1 for Hg, 3.44 to 15.28 mg kg -1 for As, and 7.17 to 19.00 mg kg -1 for Co. Chemometric techniques and geostatistics were utilized to quantify their spatial characteristics and define their possible sources. All eight metals had a moderate spatial dependency except that Pb had a strong spatial dependency. Both factor analysis and cluster analysis successfully classified the eight metals into three groups or subgroups, the first group included Cu, Zn and Cr, the second group included Cd, As and Co, and the last group included Pb and Hg. The Cu, Zn and Cr concentrations in majority samples were higher than their local background concentrations and they were highly correlated (r [ 0.80), indicating that they had similar pollution source and anthropic factor controlled their spatial distribution; the Cd, As and Co concentrations in majority samples were lower than their local background concentrations, indicating that the source of these elements was mainly controlled by natural factors; the mean concentration of Pb exhibited generally low level, close to its local background concentration, the Hg concentration in about half of samples was higher than its local background concentration, and they were poor correlated with the other metals, indicating that the source of Pb and Hg was common controlled by natural factor and anthropic factor.
