ClearExtraction and analytical methods of microplastics in wastewater treatment plants: Isolation patterns, quantification, and size characterization techniques
This review summarizes the different methods scientists use to find, measure, and identify microplastics in wastewater treatment plants. It found 12 distinct sample processing approaches and three categories of analytical techniques currently in use, but no single standardized method exists. The lack of consistent methods makes it hard to compare results across studies and fully understand how much microplastic enters the environment through treated wastewater.
