A survey was conducted to determine the status of copper and cadmium accumulations in greenhouse vegetable soils in Tongzhou of Beijing. Based on the investigated results, the contamination degree of the two heavy metals in the greenhouse vegetable soils was assessed and the main influence factors caused the accumulation of copper and cadmium was analyzed. The results indicated that there was a distinct increase of copper and cadmium concentration in greenhouse vegetable soils. The concentrations of copper and cadmium in part of soil samples exceeded the environmental quality evaluation standard for farmland of greenhouse vegetables production of China. These over-standard soil samples were mainly collected from Lucheng town and Xiji town. The contents of copper and cadmium in greenhouse soil were increased significantly as the cultivated time of the soil added. The content of copper in greenhouse soil varied from 19.8 mg/kg to 39.2 mg/kg when the cultivation time of the greenhouse increased from 1 year to 5 years, nearly increased one times. The content of cadmium in vegetable soils of 20-year age greenhouse was 3.2 times of that in 1-year age greenhouse. Significant correlations were found between the content of copper and cadmium in soil, soil organic carbon content, CEC, and available phosphorus and potassium content in soils. Soil physical and chemical properties should be considerate integrated to reduce the heavy metal contamination in greenhouse soils.

“…In recent years, with rapid development of economy and urbanization, intensive agricultural operations and heavy application of agricultural chemicals result in imbalance of distribution of soil microelements. Excessive application of chemicals in agriculture production and urban and industrial pollution may cause excess accumulation of soil microelements locally (Bhuiyan et al 2010;Liu et al 2011;Wang et al 2012;Reddy et al 2013) and subsequently pollute ground and surface water through soil erosion and water loss (García-Sánchez et al 1999;Rickson 2014). Therefore, study on the spatial distribution of soil microelements and their influencing factors in the agro-ecological environment has received focused attention in soil and environment science recently.…”

Understanding the spatial variability of soil microelements and its influencing factors is of importance for a number of applications such as scientifically formulated fertilizer and environmental protection. This study used descriptive statistics and geostatistics to investigate the spatial variability of available soil Fe, Mn, Cu, and Zn contents in agricultural topsoil (0-20 cm) in an ecological functional zone located at Yanqing County, Beijing, China. Kriging method was applied to map the spatial patterns of available soil Fe, Mn, Cu, and Zn contents. Results showed that the available soil Cu had a widest spatial correlation distance (e.g., 9.6 km), which for available soil Fe, Mn, and Zn were only 1.29, 2.58, and 0.99 km, respectively. The values of C 0/sill for available soil Fe and Zn were 0.12 and 0.11, respectively, demonstrating that the spatial heterogeneity was mainly due to structural factors. The available soil Mn and Cu had the larger values of C 0/sill (i.e., 0.50 and 0.44 for Mn and Cu, respectively), which showed a medium spatial correlation. Mapping of the spatial patterns of the four microelements showed that the decrease trend of available soil Fe and Mn were from northeast to southwest across the study area. The highest amount of available soil Cu was distributed in the middle of the study area surrounding urban region which presented as a "single island". The highest amount of available soil Zn was mainly distributed in the north and south of the study area. One-way analysis of variance for the influencing factors showed that the lithology of parental materials, soil organic matter, and pH were important factors affecting spatial variability of the available microelements. The topography only had a significant influence on the spatial variability of available soil Fe and Mn contents, parental materials, and the land use types had little influence on the spatial variability.

“…By the formula for complex quality index (P n ) in HJ332-2006 andLiu et al (2011), P n of initial and final substrate was calculated as 1.24 and 1.56 respectively, which meant they were polluted (According to HJ332-2006, P n larger than 1.0 means being polluted). The pollution was caused by Cd concentrations above the standard of HJ332-2006.…”
