“…With the acceleration of industrialization and urbanization, pollution caused by increasing concentration of heavy metal elements has become a serious concern in Anthropocene epoch, particularly for urban areas, due to heavy traffic, coal combustion, various industrial activities, and waste disposal (Craul, 1999;Buszewski et al, 2000;Rucandio et al, 2011;Jonczak, 2013, 2014;. Heavy metals with molecular weights over 40 are difficult to be decomposed or removed, and even a low concentration of heavy metals in soil and vegetation can cause harmful effects to survival and health of plants, animals, and human beings (Tan, 2004;Liu et al, 2017Liu et al, , 2020aLiu et al, , 2020bLiu et al, , 2021. To effectively control contamination, it is prerequisite to comprehend the temporal evolution of heavy metal elements and their interactions with biospheres, atmosphere, hydrosphere, and soil (Yang et al, 2012;Liu et al, 2019aLiu et al, , 2019bLiu et al, , 2019cWang et al, 2020bWang et al, , 2020cWei et al, 2020).…”

Heavy metal pollution is a serious concern in the urban area of China. Understanding metal pollution history is crucial for setting up appropriate measures for pollution control. Herein, we report a record of concentrations of 10 heavy metals (Fe, Mn, Cu, Zn, Ni, Cr, Cd, Pb, Co, and Sr) in Pinus massoniana tree rings from Fuzhou City over the past 168 years, which represents the longest tree-ring chronology of heavy metals in China. The studied metals displayed contrasting distribution patterns. Among them, Mn and Sr showed the strongest migration trend with peak concentrations at the pith. Co, Cd, and Pb also showed distinctively high concentrations near the boundary between heartwood and sapwood. Ni, Cu, Cr, and Fe showed an increasing trend possibly due to migration toward bark caused by physiological activities and increasing tourism activities and traffic pollution. The other elements (Cr, Fe, and Zn) with low migration revealed the historical pollution possibly discharged by the Fuzhou Shipping Bureau and other anthropogenic activities. Strong correlations between Cu content and temperature were found, which provides an alternative tree-ring proxy for climate reconstruction. This study provides a long-term perspective of the joint impacts of physiological, environmental, and climatological factors on the concentrations of heavy metals in southeastern China.

“…Determinations of thallium concentrations and 203 Tl/ 205 Tl ratios, in geologic and environmental settings, have enabled fingerprinting different pointsource emissions to evaluate relative source strengths, and to better understand spatial and temporal Tl distribution patterns and geochemical interactions under different physicochemical and biotic conditions. However, a study by Liu et al (2020) indicated that there might be some implications for fingerprinting some industrial point-source emissions especially when the 205 Tl/ 203 Tl ratios of processing wastes are dramatically different from those of primary raw materials. Besides, there are still very few studies on Tl isotope fractionation during weathering, soil formation, soil-plant interactions and Tl translocation in plant species under variable environmental and biological factors.…”

“…capitata L. (range of -5.4 to -2.5), which may be elucidated by anthropogenic Tl inputs (Kersten et al 2014). However, it should be stressed that the e 205 Tl ratios do not always give a basis for unambiguous interpretation, for instance, the more recent study showed considerable Tl isotope fractionation during smelting of pyrite ore for sulfuric acid production (Liu et al 2020). The raw material and four processing wastes revealed the following e 205 Tl values: pyrite ore ?…”

This overview presents the updated physicochemical characteristics of thallium and its stable isotopes (205Tl/203Tl) in the context of their occurrence and fate in abiotic and biotic systems. This also deals with the thallium behavior in geochemical interactions in and between different environmental compartments and describes its natural (geogenic) and industrial sources. The particular emphasis is placed on some extreme environments, including acid mine drainage areas where oxidation processes of Tl-bearing pyrite and other sulfides lead to very high concentrations of this metal in reactive acidic waters. Many geochemical studies have also employed stable thallium isotopes to reconstruct redox conditions in different environmental systems, to fingerprint relative pollution source strengths and to evaluate mobility of this element and its geochemical interactions in the mineral-water and soil–plant systems. This is the reason why this overview also highlights the growing potential of stable Tl isotopes in solving different geologic and environmental issues. Graphic abstract

“…These elements are just the main components of construction materials [ 5 , 7 ]. The recycling of the residue could not only realize zero emissions from the tailings’ recovery but would also offer a huge material for the building industry, which is a more effective resource recovery alternative [ 8 , 9 , 10 , 11 , 12 ]. Furthermore, its environmental risks would be effectively addressed by the construction material curing process [ 13 , 14 , 15 , 16 ].…”

Mechanical Properties and Toxicity Risks of Lead-Zinc Sulfide Tailing-Based Construction Materials

The leaching residue of the lead–zinc sulfide tailing (LRT) is the only residue generated from the tailing leaching recovery process; it is a typical hazardous material for its high heavy-metal contents and high acidity. Due to the large output of LRT, and because its main components are Ca, Si, and Al, the preparation of building construction materials with LRT was studied. The results showed that when the LRT addition is less than 47%, with the ordinary Portland cement (OPC) and fly ash (FA) added and the curing conditions appropriate, the strength values of the tested specimens meet the M15 Class of the autoclaved lime sand brick standard (GB/T 16753-1997). The carbonization coefficient and drying shrinkage of the specimen were 0.79 and smaller than 0.42, respectively. As the SEM, TG, and XRD analysis have shown, the LRT can chemically react with additives to form stable minerals. The heavy metal contents that were leached out well met the limits in GB5085.3-2007. Based on the high addition of the LRT, the good strength and lower heavy metals were leached out of the prepared test specimen, and the tailing could be reused completely with the leaching recovery and the LRT reuse process. LRT can be used to replace OPC, allowing more sustainable concrete production and improved ecological properties of LRT.
