Microplastics and the delicate balance
AI summary Read the abstract
This commentary discusses the delicate ecological balance that microplastic pollution disrupts, examining how these particles perturb aquatic food webs, alter biogeochemical cycles, and interact with climate processes. The author calls for urgent action to prevent further destabilization of critical ecosystems.
Searching for evidence of microplastic contamination, scientists at the University of New Mexico analyzed 23 human testis samples from the New Mexico Office of the Medical Investigator that were earmarked for disposal . They also obtained tissue from 47 recently neutered dogs. All the samples contained microplastics. In humans, the average concentration was 328.44 μg/g; in dogs, it was 122.63. The researchers found all the most industrially significant polymers. In both species, the most predominant polymer was polyethylene, the polymer sold around the world at the highest volume. The study also noted a negative correlation between some of the plastics and testis weight, an indication, possibly, of lower sperm counts. In recent years, study after study has detected the presence of microplastics in sensitive tissues. For example, in February, a team consisting of many of the same University of New Mexico researchers reported finding microplastics in all 62 placentas it

AI summary Read the abstract
This review summarizes the current understanding of micro and nanoplastic pollution globally, covering their sources, movement through ecosystems, and risks to both environmental and human health. The evidence shows that these tiny particles alter soil and sediment properties, disrupt nutrient cycles, and pose potential climate hazards. The authors emphasize that more research is needed on how microplastics move through food chains and affect human health, particularly through contaminated food and water.

Microplásticos en ecosistemas acuáticos: una revisión sobre su impacto y gestión
AI summary Read the abstract
This literature review analyzes the ecological impact of microplastic pollution in aquatic ecosystems and available management strategies. Researchers found that microplastics affect aquatic organisms through ingestion and bioaccumulation, altering physiological functions and acting as vectors for toxic pollutants and pathogens. While filtration technologies, bioremediation, and regulatory measures have been developed, their effectiveness remains limited and a comprehensive approach combining prevention, mitigation, and stricter policies is needed.
