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%)

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.

Ecological and agricultural risks of heavy metal pollution of soils in risky areas around Kapan City (RA) were investigated. Soil samples were collected in June 2013 and analyzed for Cr, Mn, Ni, Cu, Zn, As, Mo, Cd, Pb, Co, Hg by the mass spectrometric method. The investigations showed that the soils around Kapan copper-molybdenum combine and Geghanush tailing dump were significantly polluted with heavy metals, which may have posed serious risks not only to soil biological health, but also to agricultural production.

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.

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.

The greatest pollution earth is facing today is heavy metal pollution. So, there is a necessity to find a remedy to clear up this problem. A study was undergone by isolating the bacteria and fungi from the contaminated soil samples by determining its characteristics to resist heavy metals. Several methods have been determined to control the occurrence of the substances in the environment. Studies have shown that the isolated microbes have shown minimal inhibitory concentration. This can be used as a bioremediation method to drive away from heavy metal pollution as much as possible.

Being adapted to saline environments, halophytes are plant species that have received considerable attention due to their ability to cope with environmental stress factors, such as high concentrations of soluble salts and heavy metals. In this work, we focused on determining if the Sarcocornia neei (S. neei) plant can be considered as an indicator of heavy metal pollution in soil. This was done by analyzing the concentration of cadmium (Cd), lead (Pb), copper (Cu), and arsenic (As) in plants and soil sampled from two wetlands in the central zone of Chile: a wetland contaminated by industrial activities and a wetland protected by the Chilean government. In addition, 14 fertility parameters (pH, electrical conductivity, organic matter, nitrogen (N), phosphorus (P), potassium (K), sodium (Na), Pb, calcium (Ca), magnesium (Mg), Manganese (Mn), zinc (Zn), iron (Fe), and boron (B)) were analyzed for soil samples in both wetlands. This was done to differentiate between available elements and contamination by heavy metals. Plant and soil samples in the contaminated wetland exhibited significantly higher heavy metal concentrations in comparison to samples analyzed from the protected wetland. This indicates that the S. neei plant can be further researched as an indicator of heavy metal pollution in saline soils and possibly for phytoremediation purposes.
