“…The soil heavy metals in mining areas investigated in the research were located in different geographical locations and natural environments, and there were certain differences between studies. Therefore, the random effect model was selected to calculate its effect value [11,12]. This model took into account not only intrastudy variance but also interstudy variance (τ2), which was estimated by maximum likelihood function (REML).…”

In order to solve the intensifying problem of heavy metal pollution of soil in mining areas, a method for monitoring air quality and soil environment in mining areas based on the Internet of Things is proposed. Using meta-analysis method and health risk assessment method, the impact of mining on soil heavy metal content in Southwest China was quantitatively analyzed, and the relationship between soil heavy metal value and its potential influencing factors was discussed, as well as the heavy metal pollution, ecological risk, and health caused by soil mining activities. Risks were assessed. The results showed that artificial and oral intake were the main modes of soil heavy metal exposure, with the highest daily intakes for noncarcinogenic risk children and the highest daily intakes for carcinogenic risk adult females. The noncarcinogenic risk (HQ>1) of soil As and Pb exposure to children was 3.74 and 1.44, respectively. The carcinogenic risk values of As, Cd, Cr, and Ni in soil were all higher than 10-6, indicating that the carcinogenic risk was within the tolerance range of human body. Children were exposed to the combined noncarcinogenic risk ( HI = 3.83 ), and the risk values of the three types of recipients were 1.19 × 10 − 4 , 1.21 × 10 − 4 , and 1.06 × 10 − 4 , respectively. The correlation between heavy metal content and environmental factors was obtained. It is verified that the system in this paper can effectively monitor the meteorological environment and soil environment, and at the same time, it reveals the pollution law of heavy metals in the soil of the mining area, which provides supporting conditions for future mining and heavy metal pollution management.

“…This tendency can be associated to leaching due to topographic context, with E-W leachates circulation (Bernardo et al 2022a, b, c). Soil pH applies to the concentration of ions (H + ) present in the soil solution, being strongly attracted to negative charges and have capability to replace other cations (Altaf et al 2021;Soubra et al 2021). This parameter control soil adsorption and distribution of heavy metals (Naveed et al 2020).…”

Soils in areas surrounding landfills are constantly being enriched by heavy metals contained in the leachates, which can subsequently migrate to groundwater. The present investigation aims to characterize soil properties of 71 soil samples collected in the surroundings of Hulene-B waste dump and to determine the landfill pollution index (Ip). Soils properties studied were texture, pH, electrical conductivity, organic matter, color, and moisture. Results revealed that soils properties in the surroundings of Hulene-B waste dump were significantly altered when compared to local background. Ip index classified these soils with very high pollution, indicating a possible migration of contaminants to subsoil and groundwater, suggesting the need for intervention to mitigate the impact.

“…Moreover, citizens residing in low‐income and rural areas in Lebanon suffer from an elevated burden of disease, because practices such as open dumping and burning constitute the main methods for the treatment and disposal of hazardous and nonhazardous wastes by local administrations, resulting in the contamination of natural resources. A study conducted by Soubra et al (2021) demonstrated that various heavy metals were prevalent in samples collected form dumpsites in southern Lebanon, and many soil parameters were altered, which might have a direct effect on soil fertility, disrupt crop yield, and affect human health. A long‐term strategy for the solid waste sector remains unavailable as low diversion rates continue to be recorded, decentralization efforts remain insufficient, hundreds of open dumpsites have yet to be rehabilitated, a constant reliance of ad hoc emergency strategies persists, and the adoption of a publicly unpopular waste‐to‐energy strategy continues to be touted by the government.…”

The uncontrolled dumping of solid waste is widespread in many developing countries with most of all generated wastes being indiscriminately disposed of in an unsanitary manner that entails significant environmental and public health risks. It is imperative to prioritize dumpsites based on their relative risks so that the necessary control and remedial measures can be undertaken. This research aimed to formulate a pragmatic prioritization and rehabilitation decision tool that can be utilized in low‐ and middle‐income countries to guide decision makers in prioritizing dumpsites for remediation and in identifying the most suitable rehabilitation option for municipal as well as construction and demolition waste. The established prioritization model presents an integrated, risk‐based approach to developing a decision‐making tool for dumpsite prioritization and rehabilitation. The rehabilitation tool drew on a decision tree module to develop the appropriate remedial measures required for each site. The model proved to be effective in prioritizing uncontrolled solid waste disposal sites in Lebanon and for adopting control and remedial measures that can considerably improve decision‐making. The improper disposal of solid waste adversely affects public health and the environment in, to a greater or lesser extent, almost all low‐ and middle‐income countries. Considering that it is unfeasible to remediate all uncontrolled solid waste disposal sites at once, the proposed model facilitates the evaluation process by prioritizing sites for closure and remediation based on their relative risks.
