ClearAnalysing micro- and nanoplastics with cutting-edge infrared spectroscopy techniques: a critical review
This review evaluates cutting-edge infrared spectroscopy techniques for detecting and analyzing micro- and nanoplastics in environmental and food samples. Better detection methods are crucial for understanding human exposure because they allow scientists to measure smaller particles more accurately, including nanoplastics that are small enough to cross biological barriers and accumulate in human tissues.
Testing an Iron Oxide Nanoparticle-Based Method for Magnetic Separation of Nanoplastics and Microplastics from Water
Researchers tested iron oxide nanoparticles with hydrophobic coatings as a method for magnetically separating micro- and nanoplastics from water. The approach achieved 100% removal of larger microplastics and nearly 90% removal of nanoplastics using a simple permanent magnet, suggesting a viable method for water purification and environmental monitoring.
Citizen Observation of Plastic Pollution in African Coastal Ecosystems to Address Data Gaps in Marine Litter Distribution
Researchers engaged citizen science networks in West Africa to collect data on plastic pollution in coastal ecosystems, addressing major gaps in marine litter distribution data for the region. Community-collected observations documented high plastic loads in Nigerian, Ghanaian, and Senegalese coastal sites, demonstrating that citizen science can effectively fill monitoring gaps in data-scarce regions.
Prevalence of Microplastics in the Eastern Oyster Crassostrea virginica in the Chesapeake Bay: The Impact of Different Digestion Methods on Microplastic Properties
Eastern oysters from three Chesapeake Bay sites were found to contain microplastics, with hydrogen peroxide and potassium hydroxide digestion methods yielding the highest recovery rates, while nitric acid produced satisfactory results with better microplastic preservation.
Long‐term photo‐identification study of fin whales in the Pelagos Sanctuary (NW Mediterranean) as a baseline for targeted conservation and mitigation measures
A long-term photo-identification study of fin whales in the Pelagos Sanctuary (NW Mediterranean) identified 507 individual whales across a merged multi-decade catalogue, estimating population size, survival rates, and sex ratio from resighting data. The baseline data established by this study provides a foundation for measuring population responses to threats including ship strikes, noise, and marine pollution.
Long-term isolation at a low effective population size greatly reduced genetic diversity in Gulf of California fin whales
Researchers analyzed DNA from over 400 Gulf of California fin whales and found the population was founded roughly 2,300 years ago, has remained very small and isolated ever since, and has extremely low genetic diversity as a result. This isolation makes the population highly vulnerable to threats like pollution, ship strikes, and climate change, since it lacks the genetic variation needed to adapt.
