“…A number of studies have reported the soil quality of arable land in Chongming District, mainly focusing on the distribution and quality assessment of heavy metals and dissolved OM (Lou et al 2017;Sun et al 2010;Wang et al 2015;Zheng et al 2016). The previous studies together with the results obtained in the present study show that the soil quality of the agricultural land in Chongming District is generally good (Zhang et al 2014;Zheng et al 2016; this study).…”

This study proposed a multi-criteria evaluation system for arable land resources by combining the soil integrated fertility index (IFI) with a soil cleanliness index (based on heavy metals and metalloid content). A total of 16 typical arable land units in Chongming District, China, were evaluated using the proposed evaluation system based on 104 collected soil samples in 16 towns. The comprehensive soil evaluation scores of arable lands in 16 towns were in the range of 90.7 to 99.2 with a mean of 96.2, indicating that the arable land in all 16 towns was at the level of excellent (≥ 90.0). Lower cleanliness indices had a significant impact on the final evaluation score. In comparison with singleindex evaluation systems (i.e., the IFI or soil cleanliness index), the proposed multi-criteria system better reflects the quality of the soil. In the practice of arable land requisition and subsidy policy, the proposed multicriteria evaluation system not only encourages farmers to preserve arable lands during farming but also helps agricultural authorities make effective and reliable management decisions.

“…However, excessive concentrations can be toxic to living organisms. Heavy metal contaminants such as chromium (Cr), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) are generally more persistent than organic contaminants [4]. Metal nutritional requirements vary substantially among animals or plant species and also differ with a range of element types [5].…”

The contamination of natural environment components such as soil, sediment, water resources, and biota by heavy metals is one of the major concerns impacting environmental problems worldwide because these metals are indestructible. Furthermore, most of them are toxic to living organisms when they exceed certain concentrations [1]. The sources of environmental anthropogenic pollution by heavy metals include a variety of establishments, namely the agricultural and power industries, the transportation sector, and municipal waste management facilities [2]. Heavy metals are introduced into rivers and waterways through surface runoff and industrial effluent. The increasing tendency of heavy metal concentrations in the environment has caused great concerns globally [3]. Water bodies may consistently hold anthropogenic metals that can ultimately be transferred to humans

“…Besides, a significant positive relation was found between conductivity and heavy metals of Fe and Mn (p<0.01). In similar studies, the strong relationship and the potentiation of metal toxicity via increased water temperature or lowered dissolved oxygen levels were reported (Lou et al, 2017;Hertika et al, 2018). Consequently, the water quality of Kayacik Dam was found to be second class according to SKKY.…”

The present study was the first conducted to determine the water quality and heavy metal pollution in Kayacik Dam (Gaziantep, Turkey) to assess its suitability and safety for irrigation. For this purpose, water sampling from 6 stations was performed in spring 2019 and samples taken into polyethylene bottles were used to determine the presence of heavy metals (Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) using ICP-OES. The water temperature, pH, dissolved oxygen, and conductivity were measured in situ via 8405 Combo Water Meter. The average values of water temperature, pH, dissolved oxygen, and conductivity were as follows; 20.53 o C, 8.30, 12.57 mg/L, and 723.7 μS cm -1 , respectively. Kayacik Dam was found to be first-class water quality in terms of temperature, pH, and dissolved oxygen while it can be evaluated as a second class in terms of conductivity. Among heavy metals analyzed levels of Cd, Co, Cr, Cu, and Pb were under the detection limit of 0.05 mg/L. The order of heavy metal levels in Kayacik Dam was found as Mn>Fe>Al>Zn>Ni. A general increasing or decreasing trend was not determined in heavy metal levels among stations. According to recommended maximum element concentrations for irrigation purposes by United Nations Food and Agricultural Organization (FAO), Mn and Ni levels were found to be higher than the maximum recommended level while Fe, Al, and Zn were in the allowable range.
