“…According to present study, the pollution level of trace elements in the soil is assessed and shown in the decreasing order of Cd > As > Ba > Zn > Co = Ni = Mn = Hg > Pb > Cu = Cr > V. It can be seen that, there are some discrepancies between the partitioning results and the enrichment results, especially for Hg. These can be attributed to the complicated processes of trace elements enrichment behaviors in the soil, which can be influenced by various factors like climate conditions, soil types, as well as properties of heavy metals and their adsorbed atmospheric particulate matters (Luo et al 2015). The accumulation behaviors of trace elements in the soil can be easily influenced by the aforementioned factors and cause the discrepancies.…”

In the present study, the trace elements partitioning behavior during cement manufacture process were systemically investigated as well as their distribution behaviors in the soil surrounding a cement plant using hazardous waste as raw materials. In addition to the experimental analysis, the thermodynamic equilibrium calculations were simultaneously conducted. The results demonstrate that in the industrial-scale cement manufacture process, the trace elements can be classified into three groups according to their releasing behaviors. Hg is recognized as a highly volatile element, which almost totally partitions into the vapor phase. Co, Cu, Mn, V, and Cr are considered to be non-volatile elements, which are largely incorporated into the clinker. Meanwhile, Cd, Ba, As, Ni, Pb, and Zn can be classified into semi-volatile elements, as they are trapped into clinker to various degrees. Furthermore, the trace elements emitted into the flue gas can be adsorbed onto the fine particles, transport and deposit in the soil, and it is clarified here that the soil around the cement plant is moderately polluted by Cd, slightly polluted by As, Cr, Ba, Zn, yet rarely influenced by Co, Mn, Ni, Cu, Hg, and V elements. It was also estimated that the addition of wastes can efficiently reduce the consumption of raw materials and energy. The deciphered results can thus provide important insights for estimating the environmental impacts of the cement plant on its surroundings by utilizing wastes as raw materials.

“…As indicated by the Pb isotopic compositions and backward air trajectories, the winter northwestern monsoons and westerly jet streams were the dominant forces in the long-range transport of airborne metals in northern China, with potentially global implications. Luo et al (2016) also developed the statistics of TMs in 41 major cities and background sites of China over the past decade (Fig. 3), and the average concentrations were 285, 39.9, 75.4, 12.8, 83.4, and 622 ng m -3 for Pb, As, Cr, Cd, Cu, and Zn, respectively, higher than many developed countries.…”

“…Luo et al (2016) extracted TM datasets from China's Soil Scientific Database (http://www.soil.csdb.cn/) to demonstrate to what extent airborne TMs depositing into agricultural soils, and found that TM patterns in remote farmland topsoil and haze pollution were spatially similar, implying that airborne TMs have caused remote farmland contamination in the mid-eastern region of China as a result of long-range transport and deposition…”

“…Haze can increase atmospheric pollution by enriching with different PTEs such as As, Cr, or Cu (Luo et al 2016 ). In leafy vegetables, an increase of PTE (As, Co, Cr, Cu, Fe, and Ni) was observed after the haze episode due mainly to dust particles coming from the Sahara desert.…”

Different vegetable species and topsoils were collected from different urban gardens of Seville, Cordoba, and Huelva (South Spain) and from two small towns in a mining area (Riotinto), together with topsoil close to the plants. The concentration of potentially toxic elements (PTEs) (As, B, Ba, Cd, Co, Cr, Cu, Mo, Ni, Pb, and Zn) was evaluated in edible plant parts and in the soils. The same species were also purchased from Seville local markets and from a peri-urban area (domestic garden in a rural area) and also analyzed. Plant/soil pollution relation was studied and human health risk was assessed by different parameters. Soils of urban gardens from the mining area were more contaminated with As, Cr, Cu, Pb, and Zn in comparison with other locations, and generally, soils from cities showed higher values of As, Pb, and Zn than the peri-urban ones. The mean concentration of almost all potentially toxic elements was higher in leafy than in fruiting and bulbous species. Arsenic, Cd, and Pb concentrations were below health-based guidance values in all vegetables except Cd in one sample in the peri-urban area. In general, PTEs concentration in vegetables from city urban gardens did not exceed the one found in market vegetables for almost all studied elements, except in lettuce for almost elements. The hazard quotient (HQ) values were lower than the unit for all PTEs in plant species from the studied gardens, as well as the hazard index (HI), indicating that consumption of these vegetables can be considered safe and without risk to human health. Also, cancer risk values for As were below the established limits in all vegetables from the studied urban gardens, including those from the As-contaminated soils in the mining area.
