“…Natural phenomena such as forest fires, volcanos, mineral weathering, and erosion, also are responsible for the occurrence of heavy metals [8][9][10] .Pb(II) is a non-essential, toxic, and enzyme inhibitor heavy metal with an MCLG of zero 11 . Studies endorsed the intake of Pb(II) as an etiological factor for serious damage to the central nervous system, reproductive system, liver, and kidney [12][13][14][15] . However Pb(II) could penetrate the body by different routes, the ingestion through drinking water was known as the main pathway for Pb(II) intake 16 .…”

Valorization of waste materials and byproducts as adsorbents is a sustainable approach for water treatment systems. Pottery Granules (PG) without any chemical and thermal modification were used as a low-cost, abundant, and environmentally benign adsorbent against Pb(II), the toxic metal in drinking water. The porous structure and complex mineral composition of PG made it an efficient adsorbent material for Pb(II). The effect of key physicochemical factors was investigated to determine the significance of contact time, PG dose, pH, solution temperature, and coexisting ions, on the process. Pb(II) removal increased by PG dose in the range of 5–15 g/L, and agitation time from 5 to 60 min. Increasing Pb(II) concentration led to a drop in Pb(II) removal, however, adsorption capacity increased significantly as concentration elevated. Pb(II) removal also increased significantly from ~ 45% to ~ 97% by pH from 2 to 12. A ~ 20% improvement in Pb(II) adsorption after rising the solution temperature by 30˚C, indicated the endothermic nature of the process. The sorption was described to be a favorable process in which Pb(II) was adsorbed in a multilayer onto the heterogeneous PG surface. The qmax of 9.47 mg/g obtained by the Langmuir model was superior among many reported low-cost adsorbents. The Pb(II) adsorption was described well by the Pseudo- first-order kinetic model. Na+, Mg2+, Ca2+, Cd2+, and Zn2+ showed a negligible effect on Pb(II) adsorption. However, the presence of Mn2+ and Fe2+ significantly hindered the process efficacy. In conclusion, the use of waste material such as PG against Pb(II) is a viable option from the economic and effectiveness points of view.

“…(Tepanosyan et al, 2018;Hunanyan, 2012;Danielyan, Khoetsyan, 2009). A combination of different monitoring approaches is necessary for the assessment of pollution of environmental components: biological condition of vegetation, soil water regime, pH response, nutrient inputs, organic carbon and other agrochemical indicators (Darzi-Naftchali, Ritzema, 2018;Shokri et al, 2022;Tchounwou et al, 2012;Ali et al, 2021).…”

Environmental problems are the result of the disturbance of the natural balance through a combination of processes in the environment and their irreversible consequences. The latter causes specific environmental problems. This is particularly true for countries with limited land, water and plant resources. Factors such as soil fertility and protection against adverse effects, inactivating and demobilising chemical pollutants that penetrate the soil, etc. must be managed to ensure a stable ecosystem. Climatic factors (ambient temperature, rainfall, wind rose, etc.) also contribute to wasteful human activities. All these factors lead to soil degradation and desertification in the territory of the Republic. There are different forms of these phenomena. The extent and irreversible consequences of heavy metal contamination of biota are well documented. However, all discussions are reduced to quantitative comparisons of heavy metal concentrations in the environment with accepted maximum permissible concentrations, without focusing on the nature of what is happening. In this article, approaches with consideration of geoecological coefficients for assessment of multi-component impact of anthropogenic pollution on arable soils of the Republic of Armenia are considered. The anthropogenic zone of the city of Hrazdan and the surrounding arable soils are considered as an example of the approach to the estimation of the degree of environmental pollution. It contributes to the differentiation of abiotic and anthropogenic factors of heavy metal pollution in environmental studies. It helps to differentiate between the abiotic and the anthropogenic sources of heavy metals in studying them. This approach makes it possible to set limits on the use of natural resources. It also contributes to the development of environmental protection measures aimed at the safety of the biota as a whole.

“…The prevalence of perilous and dense elements within the customary diet gives rise to unfavorable physiological and metabolic outcomes, exerting adverse effects on both the longevity and quality of human existence (Shokri et al., 2022). Rare elements can be categorized into two principal groupings: essential elements, namely vanadium (V), copper (Cu), zinc (Zn), iron (Fe), and magnesium (Mn); and toxic elements, encompassing arsenic (As), cadmium (Cd), lead (Pb), mercury (Hg), nickel (Ni), and chromium (Cr) (Adel et al., 2016).…”

Comprehending the characteristics of heavy metal contamination within mine tailings and its ramifications on ecological and human well‐being holds paramount importance in formulating effective preventive and ameliorative strategies. This investigation evaluates the health hazards posed by the tailings originating from the Angoran lead‐zinc mine situated in Zanjan province, Iran. The mine generates two distinct types of tailings: hot filter cake (referred to as cobalt cake or S2) and cold filter cake (nickel cake or S1). Twenty subsamples were procured from each type of tailing and subjected to analysis at the pollution research laboratory of University of Zanjan. The quantification of lead (Pb), zinc (Zn), arsenic (As), cadmium (Cd), nickel (Ni), copper (Cu), chromium (Cr), mercury (Hg), manganese (Mn), and antimony (Sb) concentrations was accomplished through the utilization of inductively coupled plasma mass spectrometry (ICP‐MS). Carcinogenic and non‐carcinogenic risk assessment indices were computed. Moreover, the limits of detection (LOD) and quantification (LOQ) for the measurements were established using blank solutions prepared as samples for assessment. The Hazard Index (HI) surpassed unity for Pb, Zn, Cd, As, Hg, and Mn in both types of tailings, signifying non‐carcinogenic risk exposure for both children and adults. Furthermore, the HI for Pb and As also exceeded unity for adults. Consequently, both age groups were subject to non‐carcinogenic hazards, with children encountering notably elevated risks. The chief pathways for exposure to heavy metals and the ensuing non‐carcinogenic risks encompassed ingestion, inhalation, and dermal contact. The cumulative risk threshold for carcinogenic outcomes, in accordance with USEPA standards, ranged between 1.00E‐04 and 1.00E‐06. In this inquiry, the overall risk for children associated with tailing S1 and S2 amounted to 2.39E‐03 and 5.00E‐03, respectively, markedly surpassing the acceptable threshold. Furthermore, the cumulative risk for adults pertaining to tailing S1 and S2 stood at 1.27E‐03 and 4.68E‐03, respectively, indicating the presence of carcinogenic perils in the adult demographic.
