“…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). Unfortunately, routine monitoring for the heavy metal elements often has a short time span with strong industrial activities.…”

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.

“…Iron-based materials, including iron oxides, zero-valent iron (ZVI) and iron sulfides, are ubiquitous and widely used for heavy metal remediation because of their high redox activity (Du et al, 2016;Gong et al, 2016;Huang et al, 2016;Li et al, 2016;Liu et al, 2019a). Due to their magnetic properties, iron-based materials can be easily separated from the aqueous phase with a magnet for subsequent regeneration and reuse (Graham and Bouwer, 2012;Wang and Lo, 2009).…”

“…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 ]. Once the strength of the specimen with LRT added reaches the limit of the MU15 class construction standard (the compressive strength is 15MPa after 28 days curing process), it can be reused as foundations and other buildings [ 17 ].…”

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.
