Topic Information

Dear Colleagues,

Individuals differ in their susceptibility to environmental exposure, with susceptible subgroups such as pregnant women, fetuses, children, adolescents, and frail populations facing heightened health threats due to their increased vulnerability. Rigorously designed epidemiological, toxicological, and clinical studies are critical to establishing scientific inference, unraveling the mechanisms linking environmental exposure to health risks in these populations, and providing evidence for addressing environmental health inequalities. This Topic focuses on environmental exposure and health risks in vulnerable populations. It considers the growing complexity of environmental contaminants, with combined risks from traditional and emerging pollutants posing persistent threats to susceptible groups. We welcome original research, reviews, commentaries, and short communications addressing these challenges, with topics including (but not limited to) the following:

  • Public health and health impact assessment and environmental epidemiology;
  • Environmental risk assessments and management.

This study developed a novel adsorbent for Cr (VI) removal from wastewater by grafting N-[(dimethylamino)methylene]thiourea (TUFA) onto lignin. The resulting TUFA-functionalized lignin adsorbent AL was comprehensively characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance (NMR), and X-ray photoelectron spectroscopy (XPS). Batch adsorption experiments systematically evaluated the influence of solution pH, contact time, temperature, initial Cr (VI) concentration, and adsorbent dosage. AL exhibited high adsorption capacity (593.9 mg g−1 at 40 °C), attributed to its abundant nitrogen and sulfur-containing functional groups. Kinetic analysis revealed that the adsorption process followed pseudo-second-order kinetics. Equilibrium isotherm data were best described by the Langmuir model, indicating predominant monolayer chemisorption. Thermodynamic parameters demonstrated that Cr (VI) adsorption onto AL is spontaneous, endothermic, and entropy-driven. The adsorption mechanism involves membrane diffusion and intra-particle diffusion processes. This work successfully synthesized a stable, effective, and low-cost adsorbent (AL) using an amine agent incorporating both nitrogen and sulfur functional groups, offering a promising approach for treating Cr (VI)-contaminated wastewater.
