The effects of plastic pollution on marine organisms is of growing concern. The hydrophobic surface of plastics adsorbs organic contaminants and can alter the rate of chemical uptake in fishes. Per-fluorinated organic chemicals such as Perfluorooctanoic acid (PFOA) are highly hydrophobic toxic chemicals that adsorb to hydrophobic surfaces.

Emerging contaminants and their transformation products are widely distributed in the environment. These pollutants carry unknown risks owing to their persistence, migration, and toxicity. The wide variety and complex structures of these substances render them difficult to identify using only target analysis.

Perfluorooctanoic acid (PFOA) and its substitute, hexafluoropropylene oxide dimer acid (GenX), are widely used perfluorinated compounds (PFCs) that pose significant risks to marine ecosystems. However, the specific impacts of these contaminants on marine invertebrates, particularly echinoderms, remain poorly understood. Strongylocentrotus intermedius, a globally significant benthic aquacultural species, may be potentially affected by PFCs.

Article Synopsis
- - This study explores the levels and geographical differences of contaminants found in house dust across Europe, identifying over 1200 anthropogenic compounds using advanced techniques like mass spectrometry and suspect screening.
- - The research indicates that contaminant concentrations vary less than threefold within Europe, showing similarities with North American dust due to shared consumer products and materials.
- - It highlights geographical patterns, revealing that certain contaminants increased from north to south (like PAHs and chlorinated paraffins), whereas others, like biocides, decreased; it also emphasizes a significant risk from older, restricted contaminants, like DEHP and PCBs, despite limited toxicity data available for newer compounds.
Exposure to Pollutants and Vaccines' Effectiveness: A Systematic Review.
Vaccines (Basel)
November 2024
Department of Medical, Movement and Wellbeing Sciences, University of Naples "Parthenope", 80133 Naples, Italy.
Many human activities release harmful substances, contaminating the air, water, and soil. Since exposure to environmental pollutants is currently unavoidable, it is important to verify how these compounds may influence individual immune responses to vaccines. This review was conducted in accordance with the PRISMA statement.
