“…Natural lead comprises four stable isotopes-Pb-204, Pb-206, Pb-207, and Pb-208-in ratios that vary over time due to the radioactive decay of 238 U (206 Pb), 235 U (207 Pb), and 232 Th (208 Pb). Since anthropogenic lead has different isotopic ratios from geogenic sources such as soil, Pb-bearing media can reliably be distinguished from each other [57]. Other heavy metals used in isotopic analysis include, among others, Cd [58], Hg [59], Cu, and Zn [60].…”

This review gives insights into the levels of metals in urban dust, their determination methods, and risk assessment. Urban dust harbors a number of pollutants, including heavy metals. There are various methods used for the sampling of urban dust for heavy-metal analysis and source-apportionment purposes, with the predominant one being the use of plastic sampling materials to avoid prior contamination. There are also various methods for the determination of metals, which include: atomic absorption spectroscopy (AAS) and inductively coupled plasma-mass spectrometry (ICP-MS), among others. Studies have shown that pollutants in urban dust are mainly derived from industrial activities and coal combustion, whereas traffic emissions are also an important, but not a predominant source of pollution. The varying particle-size distribution of urban dust and its large surface area makes it easier for the deposition and transport of heavy metals. Risk-assessment studies have shown that metals in urban dust could cause such problems as human pulmonary toxicity and reduction of invertebrate populations. The risk levels seem to be higher in children than adults, as some studies have shown. It is therefore important that studies on metals in urban dust should always incorporate risk assessment as one of the main issues.

“…Furthermore, environmental degradation and hazardous dust generation possibilities remain high for abandoned mines and tailing dams [ 10 , 11 ]. Consequently, PM pollution has been a global health threat to urban population, specifically in mining localities [ 3 , 9 , 12 , 13 , 14 ].…”

Dust pollution can be severe in urban centers near mines and smelters. Identification of dust sources and assessing dust capturing plant morphological traits may help address the problem. A chromium (Cr) mining and ferrochrome smelting region in Sekhukhuneland, South Africa, was investigated to identify the sources of Cr in soil and plant leaf surfaces and to evaluate the association between Cr sources and plant morphology. Combinations of bi- and multivariate statistical analysis techniques were applied. Non-significant relation between Cr quantities in surface soil and on leaf surfaces suggested negligible Cr dust contribution from soil to leaves. Association among Cr, Fe, Mg, Al, and Si levels on leaf surfaces confirmed their shared origin, possibly from chromite containing dust dispersed by mines, smelters, roads, and tailings. Both plant morphology and Cr sources (number and proximity to mines and roads) conjointly determined Cr dust deposition on leaf surfaces. Air mass movement patterns further identified local polluters, i.e., mines, ferrochrome smelters, and roads, as dominant dust sources in the region. Common plant species showed Cr dust adhesion favouring traits (plant tallness, larger leaf area, dense epicuticular wax structures, and larger stomata) and projected dust mitigation prospects for Sekhukhuneland.

“…Large amounts of waste, such as fly ash, bottom ash, and slag, are produced during combustion. It is also acknowledged that the primary causes of atmospheric Pb deposition are I coal combustion, (ii) vehicular exhausts, and (iii) industrial emissions [1].…”

Contribution to the Serbian coal ranking and fly ash characterization using Pb isotopic ratio

The Republic of Serbia generates the majority of its electricity at the thermal power plants (TE) Nikola Tesla, Kolubara, and Kostolac. Coal is extracted from the Kolubara basin, which produces approximately 70% of lignite (an average of 30 million tons per year), and the Kostolac basin, which produces 30% of lignite. Ash, fly ash, and slag are examples of coal combustion residues. Because of the high content of potentially hazardous elements such as As, Pb, Cd, and Cr, environmental pollution with ash and fly ash has been extensively researched. Stable isotopes of lead can be used to trace lead sources. It is possible to monitor the presence, transformation pathways, and environmental impact of Pb by determining its isotopic composition in coal and fly ash. For the first time, the isotopic composition of selected coal samples from the Kolubara and Kostolac mines, as well as fly ash from the Kolubara (A and B), Kostolac (A and B), and Nikola Tesla (TENT A3, A2, B2) thermal power plants, was investigated in this study. The obtained data for 206Pb/207Pb in coal serve as the foundation for ranking domestic coals, whereas the isotopic ratios 206Pb/207Pb and 208Pb/207Pb in fly ash can be used to monitor and control lead pollution from investigated sources.
