Pollution is a global issue contributing to biodiversity loss, climate change, and human health concerns. Lead (Pb) has long been recognized as a toxic heavy metal pollutant but few studies have investigated the impact and routes of exposure to lead in field conditions and across multiple species. We collected 22 common species of butterflies across a gradient of lead pollution in the Twin Cities metropolitan area (Minneapolis and St. Paul, MN, USA). We measured their thorax lead concentrations and their body condition including wing area, number of eggs, and brain mass. We quantified lead in the soil, host plant leaves, and air (through lichen bio-monitors) at sites where the butterflies were collected to investigate potential routes of exposure. We found a negative correlation between sublethal lead concentrations and butterfly wing size across all species. Contrary to expectations from previous literature, we did not find correlations between butterfly lead concentration and number of eggs or brain mass. Our data indicate that routes of lead exposure for butterflies are particularly pronounced through soil and air, relative to exposure through their host plants, as there were positive correlations between butterfly lead and lead in nearby soil and air, but not that of host plants. Such sublethal effects of lead, even at low levels of pollution, underline the importance of continuing to reduce emissions and impacts of pollutants to protect biodiversity.

With rapid urbanization in coastal cities, the sharp increase in coastal reclamation due to human activity has caused serious land subsidence problems and threatened the safety of urban traffic in reclamation areas, especially in fast developing cities, such as Shenzhen. However, the spatio-temporal distribution of reclamation evolution and land subsidence to assist in metro operations on a regional scale remain under-explored. To fill-in this research gap, an attempt was made to monitor the coastal reclamation dynamics of Shenzhen from 1979 to 2020.The spatial-temporal changes in the reclamation were discussed based on the Landsat 5, 7 and 8 datasets along with urban growth for a 40-year period. Accordingly, the fill height distribution was employed using available global DEM datasets to perform land fill height effect of metro system in the reclamation area. After understanding the spatial-temporal patterns of land reclamation changes, we focused on monitoring the land subsidence in reclamation area using time-series Sentinel-1 Interferometric SAR (InSAR) datasets by SVD and Stacking techniques. 48 scenes were acquired during ascending and descending passes respectively between 8/3/2015 to 8/8/2023 for the study area. The field measurements of metro deformation in reclamation area acquired from investigation data reflects the risk level of metro operational risk of urban traffic. In-depth analysis of reclamation characteristics revealed a direct relationship between urban expansion, land subsidence and metro deformation. A high correlation coefficient of 0.89 was observed between land subsidence variation and the metro deformation measured along metro line 2 and line 11 in reclamation area. Understanding the impact of land subsidence on metro operation is key to refining sustainable urban development in reclamation areas.

Dissolved organic matter (DOM) constitutes the largest active carbon pool on earth, playing a crucial role in numerous biogeochemical processes. Understanding the molecular characteristics and chemical properties of DOM is essential for comprehending the global carbon cycle. However, there is a lack of systematic understanding regarding the influence of periodic flooding and drying, caused by reservoir operations, on the sources, characteristics and stability of soil DOM in the drawdown area, as well as the biotic and abiotic processes regulating DOM changes. This study employs Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) and 16S rRNA sequencing to investigate the variations in molecular and compound composition of soil DOM at different elevations in the drawdown area of the Three Gorges Reservoir, and their associations with microbial communities. The results indicate that with the increasing duration of flooding, the proportion of easily degradable DOM gradually increases in the drawdown area soils, while the proportion of refractory DOM decreases. Periodic flooding and drying enhance the microbial authigenic components of DOM, reduce the plant-derived DOM components, and significantly decrease the stability, aromaticity, and unsaturation of soil DOM. Soil DOM engages in the biogeochemical processes of the drawdown area ecosystem through coupled changes with bacteria and archaea, and changes in soil DOM result in variations in microbial necromass carbon and lignin phenol content at different elevations. The findings are significant for deepening the understanding of the biogeochemical processes involving soil DOM in drawdown areas.

Heavy metals present in coal gangue can migrate to surrounding soils through atmospheric deposition and rainwater leaching, resulting in soil heavy metal contamination. This study measured the Cd content and isotopic composition (δ¹¹⁴/¹¹⁰Cd) of surface and profile soils in a coal gangue reclamation area in eastern China and examined the impact of coal gangue reclamation on soil physicochemical properties, Cd enrichment, and retention. The results indicate that coal gangue reclamation substantially influences Cd enrichment in the soil (mean: 0.47 mg·kg⁻¹), with notable isotopic fractionation observed at different soil depths. The δ¹¹⁴/¹¹⁰Cd values display complex trends with increasing depth across various soil profiles, and the migration behavior of Cd within the soil profile is primarily governed by iron and manganese oxides. Furthermore, the significant correlation between soil pH and Cd speciation suggests that alkaline conditions markedly affect Cd mobility. Source analysis results reveal that coal gangue is the predominant source of Cd in the study area's soil. Cd pollution is not confined to the surface layers of the upper soil profiles but progressively migrates downward with depth, forming stable residual states with coal gangue oxides. These findings provide a scientific basis and theoretical support for the prevention and remediation of soil Cd pollution in coal gangue reclamation areas.

Nanofiltration contributes to water softening by the exclusion of multi-valent hardness ions, through size exclusion mechanisms. Hardness reduction can be enhanced by the addition of positive charges to the selective layer, to take advantage of repulsive electrostatic interactions. However, there are two common drawbacks to this approach: the alteration of the permeability/selectivity trade-off and the increased fouling propensity of positively charged membranes towards negatively charged organic foulants, which should be overcome for effective membrane utilization. To overcome this, positively charged aminated carbon quantum dots (CQDs) were incorporated into a positively charged selective layer to maintain selectivity against metal cations. CQDs incorporation improved membrane hydrophilicity, affected pore size distribution and molecular weight cut-off and smoothed the surface of the selective layer. As a result, membrane permeance increased by 2.3 times, up to 12 l/(m²·bar·h), compared to the pure membrane, while the positive surface charge contributed to maintaining high rejection rates for double charged cations: 92.6 % for MgCl₂ and 88.5 % for CaCl₂, and with a slight reduction of NaCl rejection from 56.5 % to 49 %. The fabricated membranes were tested for softening feed solutions simulating realistic brackish water and seawater compositions. For brackish water with total dissolved solids up to 6000 ppm, the rejection rates for Mg²⁺ and Ca²⁺ ions exceeded 93 % and 87 %, respectively, achieving total water hardness removal higher than 90 % and a Mg²⁺/Na⁺ separation factor up to 14, which can be utilized for pretreatment of brackish and sea water before the RO desalination process. Furthermore, the modification enhanced membrane antifouling properties due to improved membrane hydrophilicity and reduced surface roughness. In summary, incorporating aminated positive CQDs is an effective method for enhancing the characteristics of positively charged nanofiltration membranes for water softening as pretreatment for brackish water and seawater desalination.

This study investigated the contamination levels, ecological and human health risks, and potential sources of eleven potentially toxic metals (PETs), particulate matter 2.5 (PM_2.5), and carbon dioxide (CO₂) collected from urban-rural-periphery markets exposed to various anthropogenic activities, accentuated by the ever-increasing stress of anthropogenic activities. Contamination aspects, associated ecological risks, and hazards to human health will be discussed herein, besides determining and presenting possible sources of PM_2.5 and PETs: Cr, Cu, Co Cd, Ni, Pb, Zn, Mg, Al, Mn, and Fe. The study describes the settled dust particles from various indoor dust-collecting environments of a few supermarket chains in Kastamonu Province, Türkiye. The indoor and outdoor average levels (I/O), ratio of CO₂ and PM_2.5 concentrations was between 1.05–1.28 and 1.23–1.70 across these markets. The overall concentrations of PETs (mg kg⁻¹) indoors were observed in the following descending order: Fe (6492.73) > Al (2290.80) > Mg (719.86) > Zn (150.20) > Mn (162.13) > Ni (38.73) > Cr (18.06) > Pb (28.33) > Cu (13.67) > Co (7.87) > Cd (1.69). The I/O PM_2.5, CO_2, and PETs concentration ratios generally exhibited a multi-distribution, with peaks between 4:00–7:00 p.m., likely associated with customer density. The mean levels of children's exposure to dust particles from urban markets occurred principally through ingestion (7.53E+02), followed by dermal contact (1.10E−03) and inhalation (7.95E−06). The findings of this pioneering study offer crucial data to inform future monitoring and policy for protecting coastal ecosystems and public health.
