Understanding the historical extent of anthropogenic mercury (Hg) emissions is essential due to Hg’s persistence and toxicity, yet long-term atmospheric records are scarce. Tree rings offer a valuable high-resolution archive of historical atmospheric Hg. Here, we used Larix decidua tree rings to reconstruct a century of atmospheric Hg pollution in the Rudňany valley, a heavily contaminated mining area of Hg-rich Fe ores in Central Europe with limited historical air Hg measurements. Tree-ring Hg concentrations allowed reconstructing air Hg concentrations, reflecting changes in smelting technologies, locations and total Hg production. Among the five sites studied, the highest Hg concentrations were found at ZAV (valley entrance) and PAT (near a mining waste heap), with a maximum of 3 084 μg·kg-1 in a single tree-ring segment at PAT for a 1943–1947 segment, among the highest tree-ring Hg concentrations ever reported. Notably, peak Hg emissions occurred prior to 1960, decades before production peaked, reflecting inefficiencies in smelting technologies. A linear model was used to estimate historical air Hg concentrations from tree-ring data, with outputs consistent with the few available historical measurements. However, site-specific variation in the tree-ring Hg to air Hg ratio suggests that environmental and physiological factors influence Hg concentrations. To assess potential confounding effects, we analyzed tree growth and age-related influences on Hg accumulation. Tree age had only a minor impact on Hg trends. Growth suppression was observed at the highly polluted site ZAV, while tree-ring width at the less contaminated JOZ appeared unaffected by pollution. These findings confirm Larix decidua as a robust archive for Hg reconstruction, capable of recording pollution histories even under extreme contamination and across trees of varying ages.

Residents living in areas exposed to environmental hazards, such as abandoned mines and refineries, are hypothesized to exhibit distinct omics profiles compared with those in unaffected regions. In this article, we aimed to identify the differentially methylated regions (DMRs) affected by these hazards using Forensic Research via Omics Markers in Environmental Health Vulnerable Areas (FROM) cohort. We then evaluated the potential effects of these DMRs on 23 human diseases by using data from the Korean Genome and Epidemiology Study (KoGES) cohort, which included 79,294 participants. We conducted a DMR analysis using reduced representation bisulfite sequencing on peripheral blood mononuclear cells samples, and employed the Meet-in-the-Middle analysis to identify biomarkers that enable more precise and biologically meaningful interpretation with the forensic research via FROM cohort, and significant findings were further validated with one-sample Mendelian Randomization (MR) method. To explore relationships between these biomarkers and 23 diseases, the two-sample MR approach within the KoGES cohort was conducted. Our findings indicate that long-term exposure to heavy metals in environmentally vulnerable areas alters methylation patterns, potentially affecting disease risk. Notably, a DMR in the IL10RB gene region was identified, where hypomethylation was associated with the development of lung cancer (P = 1.92 × 10-3, β = -1.7830). This study highlights the potential epigenetic impact of environmental exposures and underscores the importance of uncovering biomarkers linking exposure to disease outcome.

Oceanic plastic pollution provides surfaces for microbial biofilm development, which may potentiate ecosystem dysbiosis by releasing toxins, providing carbon for microbial growth, and transporting pathogens and invasive species. This study investigated how plastic type, physico-chemical characteristics, ultraviolet-ageing, water temperature, depth and submersion duration (up to twelve weeks) influence marine plastisphere communities across Aotearoa New Zealand. Initial colonisation was dominated by diatoms, with network analyses identifying keystone diatom taxa such as Bacillariaceae during the first week, followed by bacterial taxa such as Sulfurovum by week two. Early-stage community composition differed between seawater and hard surfaces (plastic and glass), and between plastics. Bacterial alpha-diversity was reduced on more hydrophobic plastics, while beta-diversity was influenced by manganese and zinc content (for bacteria), and crystallinity (for diatoms and bacteria). Random Block-Forest modelling revealed distinct microbial associations with polyamide and polyolefins (LLDPE and oxo-LLDPE), whereas PET exhibited lower taxonomic specificity and was frequently misclassified as PLA, its fellow polyester. Considering risk species, the pathogen Balamuthia was present on plastics but not from seawater, and the non-indigenous tunicates Ciona savigny and Ascidiella aspersa, and plant pathogen Puccinia graminis, were important plastic-specific indicator species. Our findings contribute to a holistic understanding of how plastic physico-chemical properties shape marine plastisphere dynamics and succession. They also highlight how plastics act as selective substrates for harmful and invasive species, posing risks to biodiversity, ecosystems, and marine industries.
