Microplastics-bacteria interfacial interactions undermine disinfection performance in drinking water systems
AI summary
This study characterized plastic pollution in the Karnaphuli River of Bangladesh, documenting microplastic abundance and composition in water and sediment samples from an industrially impacted river system. The findings reveal heavy contamination from textile and industrial discharge, reflecting Bangladesh's plastic waste management challenges.

A mini-review on microplastics in drinking water treatment processes
AI summary Read the abstract
A review of drinking water treatment plants worldwide found that while processes like coagulation, filtration, and disinfection remove significant portions of microplastics, removal efficiency varies widely and no current standard treatment achieves complete elimination. This gap between laboratory findings and real-world treatment conditions means measurable microplastic concentrations persist in treated tap water consumed by billions of people daily.
Review of the Potential Effects and Remediation Strategies of Microplastic Pollutants in Drinking Water Sources
AI summary Read the abstract
Tiny plastic bits called microplastics have been found in drinking water in 42 countries, getting in through sources like bottled water packaging, laundry runoff, and wastewater. This review of existing research shows these plastic particles can act like tiny rafts, carrying harmful chemicals and heavy metals into your water that have been linked to health problems like anemia and liver damage. While scientists are still working out exactly how much harm the plastics themselves cause, the pollutants they carry are a real concern worth paying attention to, and the review also offers ideas for filtering them out of our water supply.
Factors Impacting Microplastic Biofilm Community and Biological Risks Posed by Microplastics in Drinking Water Sources
AI summary Read the abstract
Exposing microplastics from two rivers to controlled conditions for 21 days showed that bacteria preferentially colonize microplastic surfaces over open water, forming distinct biofilm communities with higher diversity and enrichment of potential pathogens including Mycobacterium. These microplastic-associated biofilms pose a dual risk to drinking water safety: carrying waterborne pathogens and potentially evading conventional water treatment processes.
Microplastic in Drinking Water: A Pilot Study
AI summary Read the abstract
This pilot study detected and characterized microplastic particles in drinking water samples, providing early evidence that plastic contamination survives conventional water treatment processes and reaches the tap. The presence of microplastics in drinking water represents a direct and daily human exposure route, with implications for long-term cumulative body burden in consumers.
