Evaluación del contenido en microplásticos en humedales de la provincia de Albacete
AI summary Read the abstract
This study assessed microplastic contamination across wetlands in the Community of Madrid, Spain, measuring particle abundance, type, and distribution. Results revealed widespread microplastic presence across sampled sites, with composition reflecting regional plastic use and land-use patterns. The findings underscore the vulnerability of freshwater wetland ecosystems to plastic pollution in urbanized landscapes.
La contaminación por microplásticos (MPs) es una amenaza global creciente que afecta a los ecosistemas acuáticos. Este estudio investiga la presencia y distribución de MPs en seis humedales de la provincia de Albacete (Castilla-La Mancha, España), clasificados según el uso predominante del suelo en sus cuencas de drenaje: antropogénicos (AP, agrícola/ ganadero) y no antropogénicos (NAP, forestal).

Unseen contaminants in Portuguese reservoirs: linking microplastics to ecological potential and human pressures
AI summary Read the abstract
Water samples from two Portuguese reservoirs (Rabagão and Aguieira) collected throughout 2023 revealed microplastic contamination correlated with ecological quality indicators and proximity to human pressures, suggesting MPs should be incorporated into freshwater quality assessments.
Microplastics Contamination in Water and Sediments: Seasonal and Spatial Distributions from the Urban Wetlands of Coimbatore, Tamilnadu, India
AI summary Read the abstract
Seasonal and spatial monitoring of three urban wetlands in Coimbatore, India found microplastic concentrations of 10–33 particles/L in surface water and 14–47 particles/0.5 kg in sediments, with monsoon season driving peak abundance and polyethylene terephthalate as the dominant polymer. Urban wetlands act as accumulation and transfer zones for microplastics, connecting city waste streams to aquatic biota and downstream human exposure.
