Spatial Distribution and Evaluation of Cadmium in Agricultural Soils Based on GIS: A Case Study of Chaoyang City in China

To identify the concentration and spatial distribution of cadmium (Cd) in agricultural soils, 207 soil samples were collected from Chaoyang and analyzed based on pollution index methods and GIS. The concentration of Cd in the soils of Chaoyang ranged from 0.030 to 0.687 mg/kg, with an average concentration of 0.246 mg/kg. The evaluated results of Cd in agricultural soils of Chaoyang shows that the pollution excess rate is 2.90%, the total agricultural soil environment of Cd was still clean, but some areas were accumulated by Cd. The differences between two evaluated methods indicate that evaluated criteria had a direct impact on the evaluation results, compared to integrated pollution index, the Geoaccumulation index method was more accurate and objective.

Abstract Historical mining activities are a source of environmental pollution that affects the food chain and the health of human beings. The aim of this study was assessment the accumulation of arsenic and lead in vegetables grown in agricultural soils contaminated by old mining in Zacatecas, Mexico. The concentration of arsenic and lead in agricultural soil and edible parts of carrot, garlic, and pepper was analyzed by atomic absorption spectrometry. The soil-vegetable bioconcentration factor and pollution load index were determined. The pH values of the farmland were alkaline. The concentration of arsenic in agricultural soil exceeds the permissible limit for arsenic of Mexican standards and international representing health risks. The lead content in most soil samples they were low. The arsenic and lead content in edible parts of species vegetable exceeded the national standard from various countries and the values established by the Codex Alimentarius (FAO-WHO). The highest arsenic concentration was found both in Capsicum annum and Allium sativum. The highest concentration of Pb was in pepper fruits. Among vegetable the high BCF value was for arsenic, ranging from 2.33 to 0.64, and the average for all vegetable samples was 1.01. The pollution index indicates that arsenic is the dominant pollutant accumulated in soil and vegetables grown in agricultural soils. According to the findings, the state and national agricultural and health authorities should not recommend the cultivation of vegetables in agricultural soil located in this area of historical mining activities. Likewise, preventive measures must be taken on the consumption of contaminated vegetables and certifying their safety.

Lignite Coal

Abstract Lignite coal is a major and an essential domestic energy source in Turkey. Many environmental problems and human health hazards may arise during lignite coal exploitation, combustion, and waste (fly and bottom ash and slag) disposal. In addition, lignite-burning power plants can be significant contributors to deposition of radiotoxic elements and/or toxic heavy metals on soil and water. The concentrations of thorium (Th) and uranium (U) in a 140 agricultural soil samples collected from the vicinity of a lignite-burning thermal power plant (LBTPP), located in Kangal district of Sivas province in the Central Anatolia region of Turkey, were determined using energy dispersive X-ray fluorescence spectroscopy. The concentrations of Th and U varied from 2.9 to 12.7 μg g−1 with an average value of 5.8 μg g−1 and 0.3–12.3 μg g−1 with an average value of 1.5 μg g−1, respectively. The radiotoxic elements pollution in agricultural soils was evaluated using pollution indices such as geo-accumulation index (Igeo), enrichment factors (EF), pollution index (PI) and Nemerow integrated pollution index (NIPI). The average value of Igeo, EF and PI estimated for Th and U were found as −1.8, 1.2 and 0.44 and −1.7, 1.7 and 0.58, respectively. The results indicated that the soils around Kangal LBTPP were practically unpolluted to low polluted with Th and U. The NIPI values varied from 0.3 to 4.0 with an average value of 0.6. The evaluation result of NIPI revealed that 86 % of total soil samples were non-polluted.

Concentration of 7 heavy metals in 269 topsoil samples were determined which collected from Shilou town of Fangshan district in Beijing, and the data was analyzed by the single factor index and the Nemerow index for the soil environment quality evaluation. The mean values of the heavy metals were 8.24 ± 1.42, 0.209 ± 0.07, 62.99 ±8.89, 0.133 ± 0.11, 25.29 ± 5.02, 23.91 ± 5.72 and 86.29 ± 28.13 mg kg-1 for As, Cd, Cr, Hg, Cu, Pb, and Zn, respectively. Average concentration of As, Cd, Cr, Cu and Zn exceeded the background value of Beijing area. It was found that all heavy metals were not in normal distribution. The soil environment quality was evaluated by single factor pollution index and Nemerow index of heavy metals. The order of single factor index was Cd, Zn, Hg, Cu, Cr, Pb, As in decreasing. Average Nemerow index of soil was 0.918. This value was reached to the grade III standard of soil environmental quality assessment classification.

Plot Analysis

The study investigated potential toxic elements in soils and food flours for highway pollution using PIXE spectrometry. The contaminated soils and cassava food flours contained higher levels of the elements than their control samples, while comparison with their standard permissible limits followed similar trend which was attributable to anthropogenic influences. These were corroborated by their elevated Enrichment factor, Pollution index and Geoaccumulation index values for the elements, suggesting significant anthropogenically—derived contaminations of the soils. T-test value (0.038) for the elemental composition of the contaminated soils & cassava flours was significant due to considerable higher concentrations of the elements in the soils than the cassava flours. Cross plot analysis result for the contaminated soils and cassava fours showed moderate positive correlation (R2 = 0.426), indicating inter-element relationship between them. Cluster analysis results for the analyzed elements in the contaminated soil samples indicated that Mn, Fe, V, Cr, Zn, Cl, Ti and S showed closest inter-element clustering and was corroborated by the results of Pearson correlation matrices, while inter-element clustering in the food flour followed the same trend and was also supported by their results of Pearson correlation matrices, validating that the soils and cassava flours were contaminated via similar sources.

Abstract The present study was conducted to assess heavy metals contamination in agricultural soils in the National Capital Region, Delhi. A total of 84 soil samples were collected from selected agricultural areas located near industries, national highways, state highways, Yamuna floodplain, residential complexes, and wastewater irrigated soils. Heavy metal concentrations (Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn), pH, and organic carbon (%) were analyzed in the collected soil samples. The average value of pH and organic carbon in the soil samples collected were 7.79±0.49 and 0.53±0.17 percent. Average concentrations of heavy metals in soils were found to be in the order of Fe> Al>Mn> Zn> Ni>Cr> Cu>Pb> Co> Cd with value as 14916.92 mg kg -1 , 13538.87 mg kg -1 , 277.16 mg kg -1 , 74.53 mg kg -1 , 35.34 mg kg -1 , 33.68 mg kg -1 , 22.94 mg kg -1 , 18.45 mg kg -1 , 1.88 mg kg -1 , and 0.92 mg kg -1 . A very high concentration of Fe (6640.09-32650.23 mg kg -1 ), Al (5631-27209.99 mg kg -1 ), Mn (73.8-735.72 mg kg -1 ), Zn (16.45-221.88 mg kg -1 ), Ni (7.63-192.63 mg kg -1 ), and Cr (9.65-127.21 mg kg -1 ) were recorded in agricultural soil samples. The average concentrations of Mn, Ni, and Zn in the soil samples were several times higher than their concentration in Indian natural background soils. A significant potential ecological risk has been noticed in nearly all the agricultural soil samples except for the samples collected nearby residential areas. The contamination factor has shown that most of the soil samples were moderately contaminated with Mn, Ni, Fe, and Cr and some soil samples were considerably to strongly contaminated with Cd, Zn, Pb, and Ni. Wastewater irrigated soils showed a moderate to a strong degree of accumulation of heavy metals (Cd, Ni, and Zn).
