Summary: The study reveals that Baltic Sea sediments record significant loads of Cd, Zn, and Pb, influenced by redox conditions. Concentrations of these metals increased from the early 19th century to the 1970s, then decreased, but are still above pre-industrial levels. Pre-industrial Cd, Zn, and Pb concentrations were higher than those suggested by the Swedish EPA. The reduction in pollution of these metals since the 1980s highlights the importance of environmental governance.

Summary: Air pollution is a worldwide problem that affects human and wildlife health through the deposition of pollutants in the atmosphere. Heavy metals, which have high toxicity, persistence, and bioaccumulation, are significant pollutants. In an environment polluted by industry and transportation, heavy metals are deposited on plant leaves and subsequently taken up by plants. The leaf cuticle, which acts as a barrier between plant tissue and the atmosphere, plays a crucial role in the adsorption and diffusion of heavy metals. This study investigated the adsorption and permeability of heavy metals on enzymatically isolated cuticles of Ficus elastica and found significant differences in adsorption capacity and mechanisms among different metals.

Summary: This study aimed to investigate the combined ecotoxicological effects of Cd, Pb, Zn, Hg and regulation mechanisms in Solanum nigrum L. The co-exposure of these heavy metals hindered the transformation of Cd, Zn, and Hg into non-available forms. Each metal individually induced oxidative damage to S. nigrum L., but their combination further enhanced ecological toxicity. Internal regulation, such as hyperaccumulation of Cd in plant roots and immobilization in the cell wall and vacuole, and external regulation involving changes in soil microbial communities, played important roles in detoxification pathways.

Summary: In this study, a novel iron-based composite (NIC) was prepared via a one-step reduction method using refinery sludge (RS) as the reducing agent and iron ore (IO) as the iron source. NIC showed a loose, porous structure with ample active sites, including Fe0, CaAl2Si2O8, fixed carbon, and active amorphous substances. After 60 days of soil remediation using 5% NIC, the bioavailable content of multiple heavy metals (Cu, Zn, Pb, Cd, and As) decreased significantly. Magnetic recovery and analysis revealed the enrichment of heavy metals in NIC, forming new phases. NIC also enhanced soil pH, cation exchange capacity, and reduced the production cost of environmental remediation materials when using RS as a reducing agent. The safety of NIC usage was verified through HM leaching toxicity analysis. Overall, this study provides a promising approach for the resource utilization of refinery sludge and the remediation of multi-metal co-contaminated soil.

Summary: By studying the alluvial and stream sediments in the area of historical zinc smelting tradition, it was found that the abandoned slag and ore roasting residue waste dumps are the main sources of zinc, cadmium, and lead. Contaminated particles are transported by the Voglajna River into the Savinja River, and eventually reach the Sava River more than 30 km downstream, causing anomalies in the sediment levels.

Summary: This study evaluates the effects of poultry litter and its biochar on the bioavailability of heavy metals in soil. The results show that the treatments decrease the concentrations of heavy metals in the soil, but can still result in moderate to heavy contamination. Therefore, it is important to consider the levels of bioavailable heavy metals when assessing the risk of soil contamination by organic amendments.

Summary: This study applied a multi-isotope and multi-elemental characterization to different antifouling paints (APs) for the first time, to improve their tracking in marine environments. The high contents of copper and zinc were observed in APs. The elemental fingerprint analysis revealed that APs, tires, and brake pads have distinct fingerprints. However, the first attempt to apply this method in highly urbanized harbor areas showed difficulties in source apportionments.

Summary: Collembola are arthropods that live in soil and have been used as bioindicators for environmental factors. Ecomorphosis, a survival strategy triggered by elevated temperature, is a phenomenon observed in Collembola. However, there is limited research in this area, especially in English literature. A literature review was conducted to understand the concept of ecomorphosis, identify species that display ecomorphosis, and analyze its implications for community ecology. The potential use of ecomorphosis as a proxy for climate adversity was also discussed.

Summary: Conventional identification based on morphology is the preferred tool for monitoring earthworm diversity, but it requires skills that can become a bottleneck in soil ecological studies. DNA-based metabarcoding is increasingly used for monitoring soil organism diversity, but few studies have compared it with conventional methods. This study aimed to compare metabarcoding using the mitochondrial 16S rRNA region with conventional morphology-based identification. Metabarcoding captured more species than the conventional method, and the PowerMax DNA extraction kit had higher richness than PowerSoil.

Summary: Earthworms play an important role in soil ecosystem functioning and are used as indicators of ecosystem health. This study investigates the interactions between earthworms and soil microorganisms by comparing soil with and without earthworms in microcosms. The results show that earthworms increase microbial activity, decrease species richness, and shape soil prokaryotes community structure. Certain bacterial phyla were enriched, while the relative abundance of the archaeal phylum Thaumarchaeota decreased in the presence of earthworms. The study highlights the influence of earthworms on soil microbial communities and their activity, suggesting the need to incorporate earthworm-prokaryote interactions in future soil microbiome studies.
