Fish and macroinvertebrate assemblages reveal extensive degradation of the world's rivers

Researchers assessed the biological health of rivers worldwide using fish and macroinvertebrate data from over 100,000 sites across 45 countries, including the most comprehensive coverage of the Global South to date. They found that roughly one-third of assessed river sites showed signs of significant biological degradation. The study highlights that freshwater biodiversity loss is a global crisis, with pollution and habitat alteration affecting rivers on every inhabited continent.

Microplastics Contamination and Potential Health Risks in the Newly Identified Oyster <i>Crassostrea (Magallana) saidii</i> from Malaysia’s Muar River Estuary

Researchers investigated microplastic contamination in a newly identified oyster species from Malaysia's Muar River estuary and found that microplastic abundance increased with oyster age, from about 3.4 particles in juveniles to 11.6 in adults. Fibers were the most common microplastic type, making up 58% of particles found. Health risk assessments indicated low to moderate hazard levels, and the study suggests this oyster species could serve as a useful bioindicator for monitoring estuarine microplastic pollution.

Microplastics and Nanoplastics Cause Thyroid Dysfunction in Adolescent Mice through the Intestinal Microbiota-Mediated Hypothalamus-Pituitary-Thyroid Axis

Adolescent mice exposed to PP and PET micro/nanoplastics in diet showed reduced thyroid hormone levels, and fecal microbiota transplantation experiments confirmed that gut microbiota mediated thyroid dysfunction via the intestinal-hypothalamus-pituitary-thyroid axis.

Occurrence and Concentration of Micropollutants in the Middle-and Down-stream of Nakdong River

A survey of micropollutants in the middle and downstream reaches of South Korea's Nakdong River detected microplastics alongside pharmaceuticals, personal care products, and industrial chemicals, reflecting the river's passage through heavily industrialized and populated areas.

Microplastic Abundance From Pig Farm Effluent and Surface Water In Sungai Tuang, Melaka, Malaysia

Researchers found an average microplastic concentration of 487 particles per liter in surface water near a Malaysian pig farm, with fiber shapes predominating, suggesting that livestock effluent is a significant and underappreciated source of microplastic pollution in freshwater systems.
