“…Cluster III contains Pb and Zn. In our study, the mean concentration of Pb in orchard land was significantly great, which is consistent with other studies (Merry et al 1983;Merwin et al 1994;Gaw et al 2003). The elevated lead concentrations in orchard samples has been shown to be most likely due to the use of insecticides that contained lead (Gaw et al 2003).…”

“…In addition, wastewater irrigation and land application of sludge are likely important sources of Cd and Cr in soils around Guanting Reservoir (Sun and Hao 2004). In addition, the elevated concentrations of arsenic on arable land have resulted from the use of arsenic-based insecticides to control chewing insects (Merry et al 1983;NSWEPA 1995). In summary, these metals probably came from natural parent materials of soils, application of pesticide and fertilizer, and wastewater irrigation.…”

It is accepted that the historical routine use of agrochemicals may have resulted in undesirable concentrations of metals in the environment. To investigate and assess the effects of land use on concentrations of heavy metals around the Guanting Reservoir in China, 52 surface soil samples (depth of 2-10 cm) were taken from areas where four types of land use were practiced (including arable land, woodland, bare land, orchard land). The metals and metalloids (As, Cr, Ni, Cu, Zn, Cd, and Pb) were analyzed using inductively coupled plasma-atomic emission spectroscopy (ICP-AES). Significant accumulation of As, Cd, and Cr was found in soils of arable land. Based on correlation and cluster analysis, it can be concluded that Cd and Zn originate mainly from phosphate fertilizer, Pb from the use of insecticides, fertilizers, and sewage sludge as well as air deposition, and Cu from copper-based fungicides, while As, Ni and Cr might come from parent soil material. According to an ecological risk analysis of metals based on the ecological index suggested by Hakanson, the four types of land can be ranked by severity of ecological risk as follows: arable land [ woodland [ bare land [ orchard land, with a high ecological risk of Cd for all four types. Management measures for land use planners for avoiding water, soil, and sediment pollution caused by metals around the Guanting Reservoir are presented.

“…However, the smallest mean As content (6.83 mg/kg, dw) was found in orchard. It has been proposed by some experts that the arsenic concentrations in orchard soils were high, very probably due to the long-term use of arsenic-based fungicides (Gaw et al, 2003;Merry et al, 1983). We did not find high arsenic concentrations in the orchard soils along the watershed and estuarine areas of southern Bohai Sea, this may be ascribed to the use of other kinds of insecticides, based on Cu, Zn or lead rather than arsenic-based fungicides.…”

a b s t r a c tDistributions and magnitude of metals in water, sediment and soil collected from the watershed and estuarine areas of southern Bohai Sea, were investigated. The largest dissolved concentrations of As, Cu and Zn in water were 347.70, 2755.00, 2076.00 lg/L, respectively, much higher than corresponding drinking water guidelines. The greatest concentrations of Cu, Zn, Cr, Ni, Pb, As and Cd in sediments were 1462.2, 1602.17, 196.43, 67.15, 63.54, 73.86 and 1.41 mg/kg, dw, respectively. The mean concentrations of Cu, Ni, Cd, Zn, Cr, Pb and As in soils were 24.67, 24.73, 0.14, 64.75, 56.52, 25.12 and 9.34 mg/kg, dw, respectively. Land use was confirmed to be an important factor of influence on soil metal concentrations. Metal contents along the watershed of Jie River were significantly greater than in other locations. The detection of metals in relatively high concentrations from different environmental matrices in this region indicates the necessity of further studies.Ó 2013 Elsevier Ltd. All rights reserved.In the past few decades, metals contamination in the environment has been attracting increasing concern around the world due to their toxicity, persistence and bioaccumulation characteristics (Cheng, 2003;Davis and Atkins, 2001). Unlike organic pollutants which can be degraded to less harmful components by biological or chemical processes, metals are considered as not naturally decomposable. The environmental metal concentrations are influenced by both natural and anthropogenic factors including parent materials, industrial and domestic sewage discharges, mining, smelting, e-wastes recycling (Xu et al., 2011). China is currently the worlds' second largest economy as a result of rapid industrial development over the past few decades. However, this rapid economic growth has been accompanied by considerable environmental side effects, especially pollution by metals. Coastal and estuarine areas are among the most important places for human inhabitants, yet they are often the ultimate receptacles of pollutants (Pan and Wang, 2012). The distribution and contamination levels of metals in the watershed, estuaries, coastal, bay and sea environments in China have been extensively investigated (Gao and Chen, 2012;Ip et al., 2007;Zhang et al., 2009).The Bohai Sea is a nearly enclosed interior sea located in northeast China and consists of Liaodong Bay, Bohai Bay, Laizhou Bay, and the middle sea (Meng et al., 2008). Due to intensive urbanization and industrialization, Bohai Sea and nearby coastal areas and estuaries have severe metal pollution problems (Wang et al., 2011b). Particularly, its proximity to Beijing, the capital of China, makes it one of the busiest seaways in the world . Large amounts of metals are carried into this sea through either direct discharges or loads from rivers, such as the Yellow River, Liaohe River and Xiaoqing River. For example, the Liaohe River discharged 390 t of metals into the sea in 2002, and the Yellow River totally discharged 200 t of metals in 2003 (Wang andWang, 2007). The...

“…Agricultural soil is a well-studied environmental compartment, since intensive land use has been associated with inputs of soil amendments and agrochemicals (1)(2)(3) and the risk of element accumulation at phytotoxic levels. Even though copper is one of the seven micronutrients (Zn, Cu, Mn, Fe, B, Mo, Cl) essential for normal plant growth (4), its excessive use in chemicals such as fungicidal sprays to control weeds and pests may adversely affect benefi cial soil organisms and ultimately the entire agroecosystem.…”

The aim of this study was to establish the fractionation of copper and zinc in a small apple orchard using the revised (four-step) Bureau Communautaire de Référence (BCR) sequential extraction procedure and assess their potential mobility in soil. Soil samples were collected at the depth of 10 cm to 25 cm, sixteen from the orchard and fi ve control samples from a meadow located some 200 m away from the orchard. As the distribution of trace-element concentrations in the control samples was normal, they were used for comparison as background levels. We also determined soil mineralogical composition, carbonate content, soil pH, cation exchange capacity, and soil organic matter. The extraction yields of Cu and Zn from the control soil were lower than from the orchard soil (25 % vs. 34 % and 47 % vs. 52 %, respectively), which pointed to natural processes behind metal bonding in the control soil and greater infl uence of man-made activities in the orchard soil. Compared to control, the orchard soil had signifi cantly higher concentrations of total Cu (P=0.0009), possibly due to the application of Cu-based fungicides. This assumption was further supported by greater speciation variability of Cu than of zinc, which points to different origins of the two, Cu from pesticides and Zn from the parent bedrock. Copper levels signifi cantly better (P=0.01) correlated with the oxidisable fraction of the orchard soil than of control soil. Residual and organically bound copper and zinc constituted the most important fractions in the studied soils. However, the use of Cu-based fungicides in the apple orchard did not impose environmental and health risk from Cu exposure.
