Summary: The study found that anthropogenic microparticle pollution exists in groundwater and sediment, especially in sediment in caves. The concentrations of anthropogenic microparticles, especially fibers and clear particles, in water and sediment samples were positively correlated. These results indicate that microparticles in groundwater mainly come from sediment, which represents a potential source of pollution to water resources and fragile habitats in globally distributed karstic systems.

Summary: For the first time, anthropogenic microparticles (AMs) were found in samples of Trematomus bernacchii collected in 1998 in the Ross Sea. Most of the AMs identified were natural and synthetic fibers. These findings not only contribute to the understanding of pollution levels in the Antarctic ecosystem, but also highlight the presence of microplastics and anthropogenic fiber pollution in the Antarctic marine food web by the late '90s.

Summary: The conversion of natural forest into agricultural land and human settlement has led to homogenisation of avian diversity and structure worldwide. While the effects of land-use change on avian functional diversity and phylogenetic diversity are well studied in the tropics, research on this topic in the Himalayas, especially in eastern Himalayan bird communities, is lacking. Our study found that bird community occupancy decreases with human land use, bird assemblages at higher elevations are clustered both functionally and phylogenetically, and agriculture and settlement have higher functional and phylogenetic diversity compared to forests.

Summary: This study assessed the radiation dose in standard barium swallow studies (BaSS) and compared it with the national diagnostic reference level (NDRL) at a large tertiary referral center. The results showed a significant correlation between radiation dose and operator's training level, as well as for female patients of childbearing age. However, there was no significant correlation between radiation dose and the referrer's specialty. The findings suggest the need to improve operator's training to reduce radiation exposure and improve compliance with the NDRL.

Summary: Many bird species use anthropogenic materials in their nests, which can have both benefits (such as signaling and protection) and costs (such as entanglement and reduced insulation). This study found that sexual dimorphism and nest type significantly influenced the use of these materials, supporting the signaling hypothesis. However, there was no support for the age and new location hypotheses, suggesting that the use of anthropogenic nest materials is widespread throughout birds.

Summary: Monitoring litter and microplastics using Arctic mammals and birds has strengths in understanding the potential impacts on Arctic biodiversity and human health. The monitoring programs need to be designed practically and consider a range of approaches and species. Northern fulmars can be used as an environmental indicator to establish spatial and temporal trends of plastic pollution. The selection of species and locations for monitoring should be based on the priorities of local communities to enhance understanding of potential implications for human health.

Summary: Marine debris is a widespread issue in the Anthropocene global ocean, with the North Pacific being one of the most polluted regions. Plastic ingestion by marine organisms is prevalent in this region, with approximately half of the fish and seabirds and over three-quarters of sea turtles and bivalve specimens having consumed plastic. A meta-analysis of scientific literature identified 12 key bioindicator species candidates for plastic pollution monitoring in the North Pacific. Standardized data collection methods were also developed to assess temporal trends and the effectiveness of mitigation actions. This monitoring is crucial for evaluating progress towards sustainability and improved ocean health in the 21st century.

Summary: The gut microbiomes of two species of wild seabirds chronically ingesting microplastics were found to have fewer commensal microbial species but more pathogens. Microplastics are a global environmental pollutant and are consumed by various species, impacting their health in multiple ways. This study investigated the association between microplastics and the microbiomes of proventriculus and cloaca in northern fulmars and Cory's shearwaters. The presence of microplastics in the gut was significantly correlated with decreased diversity of commensal microbiota and increased presence of (zoonotic) pathogens, antibiotic-resistant microbes, and plastic-degrading microbes. These findings highlight the association between environmentally relevant concentrations and mixtures of microplastics and changes in the gut microbiomes of wild seabirds.
