This data was generated during the development of the plastic extraction from dryer lint (PEDL) method (ORD tracking number ORD-067727; QAPP J-ACESD-0034382-QP-1-0). This method effectively isolates synthetic microfibers from complex dryer lint samples. The first spreadsheet defines the column headers used in all other datasets. The dataset "export_digestion_efficiency.csv" contains the data used to calculate the digestion efficiencies of all tested solvents and was used to generate figure 2 and table s2. "export_recovery.csv" contains the data generated during recovery experiments that verified no significant losses of microfibers during filtration steps, and was used to generate table s3. "export_time_course.csv" contains data used to optimize the digestion period, and was used to generate figure 3. "raman_data.csv" contains data from all Raman analyses conducted during the method verification studies and was used to used to generate figure 4. "export_digestion_efficiency_v2.csv" contains data for additional digestions with bleach and NaOH that were added in response to reviewer comments.
