Explorando las fuentes y efectos tóxicos de sustancias sintéticas en el ambiente
AI summary Read the abstract
Researchers reviewed the environmental sources, dispersal mechanisms, and human health impacts of synthetic contaminants including persistent organic pollutants, PFAS, microplastics, and pharmaceuticals, emphasizing their resistance to degradation, bioaccumulation potential, and the regulatory and strategic advances needed to reduce human exposure.
La contaminación ambiental causada por sustancias sintéticas es un problema creciente que afecta tanto a los ecosistemas como a la salud humana. Entre los compuestos más peligrosos se encuentran los contaminantes orgánicos persistentes, sustancias fluoroalquiladas, microplásticos y fármacos. Una característica fundamental de estas sustancias es su dificultad para degradarse en el medio ambiente, lo que favorece su acumulación en entornos naturales. Además, algunas de ellas imitan moléculas naturales, alterando procesos biológicos esenciales. Este artículo aborda las fuentes, mecanismos de dispersión y rutas de exposición humana, así como su impacto en la salud. También se exploran los avances en su regulación y las estrategias necesarias para reducir su liberación y la exposición humana.

Sources of Synthetic Microfiber Pollutants in the Environment and Their Fate and Toxicity
AI summary Read the abstract
Researchers reviewed the sources, environmental fate, and toxicity of synthetic microfiber pollutants, highlighting how rapid growth in synthetic textile production has dramatically increased microfiber release into air, water, and soil, where they accumulate and pose risks to ecosystems and human health.
Microplastics as Vectors of PFAS: Adsorption Mechanisms, Environmental Fate, and Toxicological Implications
AI summary Read the abstract
This review examined how microplastics act as vectors for PFAS—so-called forever chemicals—by adsorbing and transporting these compounds through aquatic and terrestrial environments to increase combined toxic burden. The co-exposure risk is particularly concerning for human health because both microplastics and PFAS are persistent, and their interaction may amplify systemic toxicity beyond what either pollutant causes alone.
Plastic Pollution and Ecosystem Health: Sources, Pathways, Impacts, and Mitigation Strategies
AI summary Read the abstract
Researchers synthesized current knowledge on plastic pollution across terrestrial, freshwater, and marine ecosystems, tracing source pathways from industrial and domestic activities through fragmentation into microplastics and nanoplastics, and mapping impacts including trophic transfer, chemical toxicity, and biodiversity loss.
Unraveling the complexities of microplastics and PFAS synergy to foster sustainable environmental remediation and ecosystem protection: A critical review with novel insights
AI summary Read the abstract
This review examines how microplastics and PFAS (sometimes called 'forever chemicals') interact in the environment, since both often come from the same everyday products. The authors found that microplastics can carry PFAS on their surface, and when organisms are exposed to both together, the combined toxic effects including oxidative stress and reproductive harm can be worse than either pollutant alone.
Combined Toxicity of PFAS and Microplastics in Aquatic Ecosystems: Synergistic, Additive, and Antagonistic Interactions
AI summary Read the abstract
Researchers reviewed the combined toxicity of PFAS and microplastics in aquatic ecosystems, finding that while synergistic interactions receive the most attention, additive and antagonistic outcomes are also common and depend on PFAS congener, polymer type, particle size, and species—warning against treating synergy as the default response and calling for standardized mixture-based exposure protocols to enable ecologically realistic risk assessment.
