Microparticle ingestion by the endangered marine otter (Lontra felina) in a human-impacted coastal ecosystem
Microplastic pollution poses a significant, validated threat to marine ecosystems, particularly for endangered species. This study empirically assessed microparticle ingestion by the endangered marine otter (*Lontra felina*) across three human-impacted coastal localities in Peru. Analysis of scat samples revealed a prevalence of microparticles, with Pucusana exhibiting the highest concentration. Dominant particle types included fibers, primarily polypropylene.

Evaluation of pharmaceutical plastic leachates and its impact on Artemia franciscana as a model organism
Pharmaceutical packaging, predominantly composed of plastics like polystyrene, polypropylene, and polyethylene terephthalate, can release chemical leachates with potential biological consequences. This study rigorously evaluated the organic and inorganic composition of these leachates and assessed their impact on *Artemia franciscana*, a model organism, revealing concentration-dependent mortality and oxidative stress. Notably, polyethylene (EPE) and polypropylene (PP) leachates induced significant increases in reactive oxygen species (ROS) and lipid peroxidation, alongside decreased antioxidant enzyme activity.

First expedition Jaywun research vessel: assessment of microplastics from international waters, Spain to Abu Dhabi, U.A.E
The inaugural Jaywun research vessel expedition has yielded a transboundary assessment of microplastic (MP) pollution across critical international shipping corridors, from Spain to Abu Dhabi. Analyzing 100 surface-water samples collected across six regions—including the Mediterranean Sea, Red Sea, and Arabian Gulf—the study revealed MP concentrations ranging from 4 to 290 particles per liter. Notably, the Arabian Sea exhibited the highest mean concentrations, with polyester and polyethylene terephthalate dominating detected polymers.
