Soil samples of 0-5cm from 18 sampling sites including different functional zones of Qingdao, China were collected and analyzed. The results showed the average concentration of Cu, Pb, Zn and Ni in soil were up to 55.96,174.37,57.89, and 31.16mg/kg respectively, which were much higher than their natural background values. The average Igeo values were in the increasing order of Ni(0.638) <Pb(1.428)<Cu(1.458)< Zn(3.03). Zn was high contamination, while Pb,Cu were moderated contamination. By hierarchical cluster, eighteen plots could be divided into five groups.(a)(A3,C1),(C4,C5,E1);(b)(B2,E2),(D3,D2);(c)(D1,D4,A2),(A1,C6); (d) (A2,C2),B1; (e)C3; The MDS analysis showed some rules in the graph. From top to bottom of longitudinal axis means low contents to high contents of Cu,Pb. From left to right of horizontal axis means low contents to high contents of Zn. Along the oblique axis, the values of Igeo were from high to low.

Levels of lead, cadmium, and nickel in roadside soils and vegetables along a  major highway in Gazipur, Bangladesh were investigated. Soil samples were  collected at distances of 0, 50, 100, and 1000 m (meter) from the road. The  concentrations of lead (Pb) and nickel (Ni) in soil and vegetables (bottle gourd  and pumpkin) decreased with distance from the road, indicating their relation to  traffic and automotive emissions. The concentration of cadmium (Cd) was found  to be independent of distance from road. There were significant differences in  the concentrations of lead, cadmium, and nickel for different plant species and  soils at various distances. The heavy metals contents both in the soils and  vegetables for every distance from the road was found in the order  nickel>lead>cadmium. DOI: http://dx.doi.org/10.3329/bjar.v37i1.11170 Bangladesh J.

Seasonal concentrations of eight total and bioavailable heavy metals (Cr, Cu, Cd, Zn, Mn, Ni, Pb an Fe), along with some physico chemical properties of soil in vegetable farms around the rock quarry in Durumi, Abuja was assessed to know the level of heavy metal pollution of the soil. Control and actual soil samples were collected from depths of 0.0 -5.0cm and 5.0 - 10.0cm during dry and rainy seasons. Heavy metal concentrations varied inconsistently in samples and control. Dry season levels of Zn(5.20mg/kg), Mn(19.44mg/kg), Ni(1.69mg/kg) and Pb(4.56mg/kg) and rainy season levels of Zn (0.26mg/kg), Pb(22.53mg/kg) at soil depth of 0.0 - 5.0cm, and dry season levels of Zn(1.19mgkg) and Ni(1.62mg/kg) along with rainy season levels of Cr (0.44mg/kg), Cd (0.06mg/kg), Zn(0.09mg/kg) and Fe(6.74mg/kg) at soil depth of 5.0 -10.0cm were all higher in samples than controls. However, seasonal mean total heavy metals in the soil samples were lower than the Maximum Allowable Limits (mg/Kg) for World Health Organization (WHO) and Food and Agriculture Organization (FAO). During dry season, heavy metals that indicated anthropogenic content, had anthropogenic levels that ranged in the order: Cd(16.67%) < Cu(54.17%)

Ecological Hazards

Spinacia oleracea L., as the most widely cultivated green leafy vegetable in China, can threaten human health in cases of its excessive heavy metal content, especially in mining areas of karst landforms. Therefore, the present study mainly investigates whether biochar is useful for remediating heavy metal pollution in soil and S. oleracea and the degree of this improvement in karst areas. The effects of heavy metal exposure on the health of children and adults in S. oleracea and rhizosphere lime soil with six biochar levels are evaluated by a health risk assessment, namely, 4000 g of lime soil (C-0), 160 g of biochar + 3840 g of lime soil (C-160), 240 g of biochar + 3760 g of lime soil (C-240), 320 g of biochar + 3680 g of lime soil (C-320), 400 g of biochar + 3600 g of lime soil (C-400) and 800 g of biochar + 3200 g of lime soil (C-800). The results show that the pH values of the lime soil were positively correlated with Pb, P and K contents and negatively correlated with As, Cr, Hg, Cd and N contents in S. oleracea. The assessments of the potential ecological risk index show that the soil samples for the C-0 and C-160 levels pose moderate ecological hazards, while the soil samples for the C-320, C-800, C-400 and C-240 levels constitute mild ecological hazards. The single noncarcinogenic risks, total noncarcinogenic risk indexes, single carcinogenic risks and total carcinogenic risks values indicate that exposure to heavy metals in lime soil and S. oleracea poses a serious threat to human health. It also presents an unacceptable cancer risk and children are more threatened than adults. Our results suggest that heavy metal pollution of S. oleracea and its rhizosphere lime soil in karst areas still poses a threat to human health after adding biochar, and the relevant local departments need to implement more active measures to solve the excessive heavy metal contents in the local soil and vegetables of this karst regions.

the paper discussed the pollution of heavy metal in vegetable farm soils in Fuxin city, China. The levels of lead, cadmium, chromium, arsenic and mercury in 5 soil samples obtained from vegetable farm soil were detected. The levels of lead, cadmium, chromium, arsenic and mercury were17.12-34.62mg/kg,0.12-0.24 mg/kg,32.28-50.96 mg/kg,6.86-8.83 mg/kg and 0.14-0.16 mg/kg, respectively. At same time, we have done some evaluation for vegetable farm soils pollution of Fuxin. The vegetable farm soils were contaminated by mercury in great universality, and the next is cadmium. As for contaminated degree, mercury-pollution is severe, and the second were cadmium, and the rest are slightly polluted. Compared the present pollution change, soil pollution in Fuxin is aggravate, which should grasp management, especially the serious mercury pollution that should pay attention to the monitoring mercury enterprises.

Abstract Background Heavy metal pollution of aquatic systems is a global issue that has received considerable attention. Canonical correlation analysis (CCA), principal component analysis (PCA), and potential ecological risk index (PERI) have been applied to heavy metal data to trace potential factors, identify regional differences, and evaluate ecological risks. Sediment cores of 200 cm in length were taken using a drilling platform at 10 sampling sites along the Xihe River, an urban river located in western Shenyang City, China, divided into 10 layers (20 cm each). The concentrations of the As, Cd, Cr, Cu, Hg, Ni, Pb and Zn were measured for each layer. Eight heavy metals, namely Pb, Zn, Ag, Cd, Cr, Cu, Ni, and Hg, were measured for each layer in this study. Results The average concentrations of the As, Cd, Cu, Hg, and Zn were significantly higher than their background values in soils in the region, and mainly gathered at 0–120 cm in depth in the upstream, 0–60 cm in the midstream, and 0–20 cm downstream. This indicated that these heavy metals were derived from the upstream areas where a large quantity of effluents from the wastewater treatment plants enter the river. Ni, Pb, and Cr were close or slightly higher than their background values. The decreasing order of the average concentration of the Cd was upstream > midstream > downstream, so were the Cr, Cu, Ni and Zn. The trend of the average concentration of the As was different to the Cd; being highest midstream, followed by upstream and then downstream. The potential factors of heavy metal pollution were Cd, Cu, Hg, Zn, and As concentrations, especially Cd and Hg, whose ecological risks were much higher than those of Ni, Cr, and Pb. The ecological risk levels of all heavy metals were much higher upstream than midstream and downstream. Conclusions Industrial discharge was the dominate source for eight heavy metals in the surveyed area, and rural domestic sewage has a stronger influence on the Hg pollution than industrial pollutants. These findings indicate that effective management strategies should be developed to protect the environmental quality of urban rivers.

<em>A wide range of the Musi river usage such as agricultural, forestry, industry, residential, fishing and transport activities has created a heavy metal pollution isues. This research aims to know the concentration of Cu and Pb in the water column (suspended and dissolved) and also on planktons found at downstream of Musi River. Water and plankton sampling was carried out in January and May 2015 across five research stations. Cu and Pb in water and plankton samples were analyzed using the USEPA 30050B method determined by using AAS SpektrAA plus variant with air mixure flame – acetylene. The average concentration of dissolved Cu and Pb were varied from 0.003-0.005 mgL<sup>-1</sup>and 0.002-0.004 mgL<sup>-1</sup>, respectively. A higher value was observed during the suspended phase which came to around 8.60-31.79 mgKg<sup>-1 </sup>for Cu dan 21.23-61.5 mgKg<sup>-1 </sup>for Pb. Furthermore, Cu and Pb concentration in plankton were varied from 1.046-2.430 mgKg<sup>-1 </sup>and 0.673-1.283 mgKg<sup>-1</sup>, respectively.</em>
