“…As an important medium of material and energy exchange in ecological environment, soil can provide the environment and nutrition for the growth of plants and microorganisms (Adedeji et al 2020;Olatunde et al 2020). With the development of economy and society, soil environmental quality is increasingly affected by human activities, including intensive industrial and agricultural activities (Chai et al 2021), and attracted widespread attention (Wu et al 2021).…”

measured, the distribution characteristics of heavy metals in different wind directions were analyzed, and the pollution degree of heavy metal in soil was evaluated. The soil around the power plant is generally polluted by heavy metals, and the degree of pollution is heavy pollution and moderate pollution. The potential ecological hazard of heavy metals in soil is moderate or slight. The values of Nemerow index and potential ecological risk index are different among different directions and different distances from the power plant. Cd, Hg and As are the mainly contributors for the potential ecological risk. The results revealed that wind direction is important for the distribution of heavy metal around coal-fired power plant. The study can provide a theoretical basis for the prevention and management of soil heavy metal pollution around coal-fired power plant.

“…To study the ecological and environmental risks of soil polluted with heavy metals, different indicators such as Igeo, PLI, EF, and potential ecological risk index (ERI) have been developed [14,17,[20][21][22][23][24]. PLI and ERI evaluate the combined risk of multiple trace elements in soil while EF shows the relative enrichment in any contaminant in comparison to pre-industrial soils from the same environment [25].…”

The cement industry is considered as a major source of heavy metals pollution in topsoil. This study aims at measuring the heavy metal contamination level in the vicinity of Shiraz cement factory, and assessing the ecological and environmental risks associated with the factory's activities in the surrounding topsoil. To do so, 10 samples of soil were taken from around the Shiraz cement factory at the depth of 0-10 cm and the concentration of some heavy metals including Al, Cd, Ni, and Pb was measured. Enrichment factor (EF), geo-accumulation (Igeo), and pollution load (PLI) indices were used to assess the ecological risk of heavy metals.Based on the results, the mean concentration of Al, Ni, Cd, and Pb was 6,937.14, 88.09, 1.96, and 30.74 mg/kg, respectively. The EF results showed that due to anthropogenic activities, the Ni, Pb, and Cd element has moderate, severe, and very severe enrichment in the study area, respectively. The Igeo result for Al, Ni, Pb, and Cd was -0.82, -0.17, 0.16, and 0.68, respectively, which indicates non- to slightly pollution of these heavy metals in this region. The mean PLI in the study area was 1.4 indicating the low to medium pollution of heavy metal. The results of this study can be useful in determining and investigating the environmental effects of Shiraz cement factory.

Fate of Lead and Cadmium in Precalciner Cement Plants and Their Atmospheric Releases

et al. 2021

Disclosing the fate of lead (Pb) and cadmium (Cd) during the cement production process is the key to control their atmospheric emissions, which have not attracted much attention yet. In this study, three precalciner cement plants (CPs) using different raw materials in Guizhou Province in Southwest China were investigated. It showed that the concentrations of Pb and Cd in different raw materials and the associated total metal input of these materials were different among CPs; the behavior of Pb and Cd were almost the same during the clinker production process that there has been no accumulation of these two elements inside the system, and nearly all input of Pb and Cd were discharged by the clinker. Although the temperature of clinkerization was pretty high of 1450 °C, the atmospheric emission ratio of both metals was negligible (<0.006% for Pb and <0.002% for Cd of the total output, respectively); the main reason might be that the two elements were incorporated into the minerals of clinker, either as silicate or sulfate. The long-term environmental impacts of some high Pb-and Cd-laden clinkers and cement need to be monitored and evaluated.
