ClearImpact of phenolic-formaldehyde resin microplastics on anaerobic granular sludge: EPS interaction mechanisms and impacts on reactor performance
Researchers studied how microplastics made from phenolic-formaldehyde resin affect wastewater treatment systems that use anaerobic granular sludge. They found that smaller microplastic particles provided new surfaces for bacteria to grow on, initially boosting treatment performance, but over time the increased microbial activity weakened the structure of the sludge granules. The study reveals a trade-off where microplastics can temporarily improve wastewater processing while ultimately destabilizing the treatment system.
An Integrated Assessment of Microplastic Pollution in Coastal Surface Water and Sediment of Japan
Researchers conducted a comprehensive survey of microplastic pollution in surface water and sediment at 15 coastal locations across Japan, from Hokkaido to Okinawa. They extracted over 53,000 suspected microplastic particles and identified the most common polymers using FTIR spectroscopy. The study provides an integrated baseline dataset for understanding the extent and distribution of microplastic contamination along Japanese coastlines.
