“…Heavy metals are among the most dangerous pollutants, and the seriousness of these pollutants is due to their toxicity and tends to accumulate in the soil and tissues of living organisms as well as their degradable behavior (Dalman et al, 2006;Akbarzade, 2015;Baghvand et al, 2010).Heavy metals are defined as metals or semi-metals whose density is more than (5 g/cm 3 ) (Sussiu et al,2008). Heavy metals occur naturally, but they also enter into the ecosystem throughout at different concentrations of the anthropogenic activity (You et al, 2015). Heavy metals, among them, are necessary for living organisms but at low concentrations and are toxic at high concentrations such as iron, zinc, chromium, and copper, while lead, cadmium, and mercury are considered as unnecessary elements that have no vital role yet and are toxic at any concentration (McGrath et al, 2001) Soil is the main storehouse of heavy metals that are emitted to the environment, and that soil pollution, especially agricultural ones, has raised the interest of specialists in this field, not only because of the accumulation of these minerals in the soil but because of the transfer of these toxic metals to crops that grow in polluted soils leading to their entry into the food leading to a significant effect on human health; in addition to plant growth and development (Huand et al, 2007).…”

This study was conducted to estimate the level of some heavy metals, mainly Lead (Pb), cadmium (Cd), chromium (Cr) and cobalt (Co) in the soil and wheat leaves of some wheat fields in Basra and Maysan province; the sampling areas were Al-Qurna, Al-Madinah, Al-Amara, Kumit, Ali Al-Sharqi, and Ali Al-Gharbi. It was performed the analysis using the Flame Atomic Spectrophotometer. The results indicated an increase in the concentrations of above mentioned these heavy metals in all examined areas; the levels in agricultural soils were found to be exceeding the internationally permissible limits according to EU-2000 standards, the highest levels of pollution were observed at Al- Qurna site with significant differences than other sites for both available and total HMs concentrations in soils. Indicating that the arrangement of the metals according to their available concentrations in the analyzed soil was as follows: lead (21.32 )˃ cobalt (14.63) ˃ chromium (11.06) ˃ cadmium (1.15) as mg/Kg of soil. Additionally, results showed that the highest lead content in the wheat leaves was examined in the Qurna fields (0.175 mg/kg), followed by Amara with a concentration of 0.136 mg/kg. The lowest concentration of lead was observed in wheat leaves in the Kumit fields (0.007 mg/kg). In terms of Cd concentration in wheat leaves, the highest level was observed in Al-Qurna, with a significant difference from other fields, reaching 0.009 mg/kg. The lowest concentration of this HM was recorded in Ali Al-Gharbi, which reached 0.002 mg/kg. The results of the correlation between the available concentration of heavy metals elements and soil characteristics revealed a significant correlation between the soil pH and lead, cadmium, and chromium available concentrations, whereas no correlation with cobalt and a significant correlation between soil EC and lead was observed and a highly significant negative correlation with the cobalt. Results proved the high levels of pollution in all examined areas in Basra and Maysan provinces.

“…However, as a result of the long-term high-load mining activities lead to dozens of gangue dumps have accumulated to different scales, which occupies a great quantity of the land resource and poses a huge challenge to the safe development of agricultural activities and products [20]. While the trace elements in coal gangue have a great impact on the environment, limited studies have been conducted on the distribution characteristics and environmental quality evaluation of the trace elements in the soil of mining area in Huainan coalfield [19,[21][22][23][24], but no further researches carry out ecological risk assessment of trace elements in coal gangue. It is necessary to conducted on the speciation distribution and ecological risk assessment of trace elements in Huainan coalfield in terms of the stacking management and comprehensive utilization of coal gangue.…”

Coal gangue is the solid waste discharged in the process of coal mining, washing and processing [1,2]. The production of coal gangue accounts for about 10%-15% of the raw coal output [3], and it is one of the main sources of industrial solid waste in China [4,5]. Accompanied by the huge consumption of coal resources, leading to the continuous generation of coal gangue. [6,7]. Coal gangue is a mixture of a variety of rock and mineralogical components with low carbon content [4]. The discharge and open-air dumping of coal gangue occupy a large number of land resources, which also result in the release of environmentally sensitive trace elements and other toxic and harmful

“…Although they occur naturally, heavy metals also enter into environment throughout anthropogenic activities (You et al, 2015). The increasing of anthropogenic activities leads to intensifying emission of various pollutants including heavy metals, such increase in these activities may cause a genuine health hazard to both people and plant (Onder and Dursun, 2006).…”

Abstract. Heavy metals pollution has become a worldwide problem, and its toxicity affects crop yield, environment, human and animal health, as well as, soil fertility. In this study, the quantities of different heavy metals including Pb, Cd, Cr and Co have been assessed in Basra governorate. Soil and date palm Phoenix dactylifera L. leaves have been collected from different sites (Zubair highway, Najibya electric power station, Faw, Qurna, Shat Al-Arab and Abo Al-Kaseeb districts) during the rainy and dry seasons. The analysis of heavy metals revealed that the total, available and leaf content of Pb was found to be high at all investigated sites during both season, followed by Cr, while the lowest averages of heavy metals were reported with Cd. Results indicate that the total level of heavy metals pollution during the dry season was higher than what was observed during rainy season in all analysed heavy metals. It is noteworthy, that the levels of Pb and Cd in Basra's soils have exceeded the permissible limits according to European standards, thus, an urgent interaction is required to decrease these levels by introducing a suitable remediation procedure.
