  • organic contamination and remediation in the agricultural Soils of china a critical review
    Science of The Total Environment, 2018
    Co-Authors: Yu Zhan, Daniel C W Tsang, Jianteng Sun, Lili Pan, Lizhong Zhu
    Abstract:

    Abstract Soil Pollution is a global problem in both developed and developing countries. Countries with rapidly developing economies such as China are faced with significant Soil Pollution problems due to accelerated industrialization and urbanization over the last decades. This paper provides an overview of published scientific data on Soil Pollution across China with particular focus on organic contamination in agricultural Soils. Based on the related peer-reviewed papers published since 2000 (n = 203), we evaluated the priority organic contaminants across China, revealed their spatial and temporal distributions at the national scale, identified their possible sources and fates in Soil, assessed their potential environmental risks, and presented the challenges in current remediation technologies regarding the combined organic Pollution of agricultural Soils. The primary pollutants in Northeast China were polycyclic aromatic hydrocarbons (PAHs) due to intensive fossil fuel combustion. The concentrations of organochlorine pesticides (OCPs) and phthalic acid esters (PAEs) were higher in North and Central China owing to concentrated agricultural activities. The levels of polychlorinated biphenyls (PCBs) were higher in East and South China primarily because of past industrial operations and improper electronic waste processing. The co-existence of organic contaminants was severe in the Yangtze River Delta, Pearl River Delta, and Beijing-Tianjin-Hebei Region, which are the most populated and industrialized regions in China. Integrated biological-chemical remediation technologies, such as surfactant-enhanced bioremediation, have potential uses in the remediation of Soil contaminated by multiple contaminants. This critical review highlighted several future research directions including combined Pollution, interfacial interactions, food safety, bioavailability, ecological effects, and integrated remediation methods for combined organic Pollution in Soil.

  • prospective sustainable production of safe food for growing population based on the soybean glycine max l merr crops under cd Soil contamination stress
    Journal of Cleaner Production, 2019
    Co-Authors: Jie Zhan, Irena Twardowska, Siqi Wang, Yanqiu Chen, Mihajlov Ljupco
    Abstract:

    Abstract Sustainable food production for steadily growing world's population under the conditions of increasing environmental stress and Soil Pollution is a challenge that calls for optimization of farmland resource management. Soybean (Glycine max. L. Merr) as one of the world's most important protein crops can play a leading role in addressing global food security provided it fulfills safety requirements, in particular with respect to Cd level. The aim of this comparative study was elaborating efficient methods for the selection of soybean cultivars assuring safe Cd contents for food/feed purposes. The pot culture experiment was conducted using 15 soybean cultivars grown in Soil moderately polluted with Cd (1.98 mg kg−1), and in unpolluted Soil (0.15 mg Cd kg−1) as a control. The evaluation was based on the novel Cd concentration/load trend analysis in plant tissues, Seed Accumulation Factors SAFn and Cd load balance. The soybean demonstrated fundamentally different response of the same cultivars to low and moderate Cd concentrations in Soil. In cultivars grown in unpolluted Soil, besides genetically determined detoxification factors, important seed protective role played Cd accumulation in stem, leaves and root (Seed Accumulation Factor SAFn 0.5 up to >1, whereas Cd load in bean ranged from −23 to +11% related to mean value in shoot). Root to shoot flux rate was found to be a decisive factor in Cd enrichment in soybean seed at the elevated Soil Pollution with Cd. The efficient screening for safe Cd content in soybean should be thus based on EF and Cd concentrations in shoot at the actual target Soil Pollution level.

The evaluation was based on the novel Cd concentration/ load trend analysis in plant tissues, Seed Accumulation Factors SAFn and Cd load balance. The soybean demonstrated fundamentally different response of the same cultivars to low and moderate Cd concentrations in Soil. In cultivars grown in unpolluted Soil, besides genetically determined detoxification factors, important seed protective role played Cd accumulation in stem, leaves and root (Seed Accumulation Factor SAFn0.5 up to >1, whereas Cd load in bean ranged from �23 to þ11% related to mean value in shoot).

  • current status and associated human health risk of vanadium in Soil in china
    Chemosphere, 2017
    Co-Authors: Jie Yang, Yanguo Teng, Rui Zuo, Haiyang Chen, Guoqiang Wang, Liuting Song, Weifeng Yue, Yuanzheng Zhai
    Abstract:

    Abstract A detailed assessment of vanadium contamination characteristics in China was conducted based on the first national Soil Pollution survey. The map overlay analysis was used to evaluate the contamination level of vanadium and the non-carcinogenic risk assessment model was calculated to quantify the vanadium exposure risks to human health. The results showed that, due to the drastically increased mining and smelting activities, 26.49% of Soils were contaminated by vanadium scattered in southwest of China. According to Canadian Soil quality guidelines, about 8.6% of the national Soil Pollution survey samples were polluted, and pose high non-carcinogenic risks to the public, especially to children living in the vicinity of heavily polluted mining areas. We propose the area near the boundary of Yunnan, Guizhou, Guangxi, and Sichuan provinces as priority control areas due to their higher geochemical background or higher health risks posed to the public. Finally, recommendations for management are proposed, including minimization of contaminant inputs, establishing stringent monitoring program, using phytoremediation, and strengthening the enforcement of relevant laws. Therefore, this study provides a comprehensive assessment of Soil vanadium contamination in China, and the results will provide valuable information for China’s Soil vanadium management and risk avoidance.

  • a geochemical survey of trace elements in agricultural and non agricultural topSoil in dexing area china
    Journal of Geochemical Exploration, 2010
    Co-Authors: Yanguo Teng, Jinsheng Wang, Rui Zuo, Jie Yang
    Abstract:

    Abstract In China, Soil Pollution is very serious, which has jeopardized the ecology, food safety, the people's health, and even the sustainable development of agriculture. In order to investigate the Soil Pollution situation, a total of 874 agricultural and non-agricultural topSoil samples were collected from Dexing area, northeast of Jiangxi Province, China. The total elemental concentrations of 17 elements (As, Hg, Mo, Cd, Cr, Zn, Cu, Mn, Ti, Pb, Fe, Ca, K, Si, Al, Mg, and Na) were determined. The geochemical background and threshold was predicted with the method of the median ± median absolute deviation (MAD). The agricultural Soil median concentration of trace elements was similar to that of the non-agricultural Soil. In contrast to Jiangxi Soil background of trace elements, the geochemical background of the study area was obviously higher. The maps of the Pollution indices for As, Cd, Cr, Cu, Hg, Mn, Mo, Pb, Ti and Zn of non-agricultural Soil and agricultural Soils in the study area, showed that the highest level of Pollution is distributed near and along the Lean River, especially in the neighboring and surrounding Dexing and Leping mining area.
