文摘

Microplastic (MP) was analysed in effluents from 4 tertiary and 8 secondary WWTPs. Micro-FT-IR imaging allowed polymer identification of all MP down to a size of 20 μm. MP was determined in all effluents of examined WWTPs. An installed post-filtration (tertiary treatment) removed 97% of MP. WWTP may act as MP source but also as sink since MP was detected in sewage sludge.
