Abstract

Soil polycyclic aromatic hydrocarbons (PAHs) and cadmium (Cd) pollution poses severe threats to environment security. Previous studies have reported that both nanoparticles and humic acid (HA) have ability to phytoremediate of pyrene/Cd in soil. Here, pot experiments were conducted to investigate the effects of TiO₂NPs and humic acid addition on the applicability Hylotelephium spectabile of remediation for pyrene-Cd co-contaminated soil and the corresponding plant growth. The results show that TiO₂NPs with HA can mitigate the damage to plant physiology. TiO₂NPs-HA is more suitable to be applied on composite soil where Cd pollution is dominant and pyrene pollution is light. Furthermore, the coating of TiO₂NPs with HA enhances the availability of Cd and expands root xylem, allowing roots to absorb and accumulate Cd in large quantities finally. This study aims to establish a theoretical foundation for the implementation of sedum plant in remediating soil contaminated with multiple pollutants.

期刊介绍： The Journal of Environmental Chemical Engineering (JECE) serves as a platform for the dissemination of original and innovative research focusing on the advancement of environmentally-friendly, sustainable technologies. JECE emphasizes the transition towards a carbon-neutral circular economy and a self-sufficient bio-based economy. Topics covered include soil, water, wastewater, and air decontamination; pollution monitoring, prevention, and control; advanced analytics, sensors, impact and risk assessment methodologies in environmental chemical engineering; resource recovery (water, nutrients, materials, energy); industrial ecology; valorization of waste streams; waste management (including e-waste); climate-water-energy-food nexus; novel materials for environmental, chemical, and energy applications; sustainability and environmental safety; water digitalization, water data science, and machine learning; process integration and intensification; recent developments in green chemistry for synthesis, catalysis, and energy; and original research on contaminants of emerging concern, persistent chemicals, and priority substances, including microplastics, nanoplastics, nanomaterials, micropollutants, antimicrobial resistance genes, and emerging pathogens (viruses, bacteria, parasites) of environmental significance.
