So far, several classes of digesting solutions have been employed to extract microplastics
(MPs) from biological matrices. However, the performance of digesting solutions across
different temperatures has never been systematically investigated. In the first phase of the
present study, we measured the efficiency of different oxidative agents (NaClO or H 2 O 2),
bases (NaOH or KOH), and acids [HCl or HNO 3; concentrated and diluted (5%)] in digesting
fish tissues at room temperature (RT, 25° C), 40, 50, or 60° C. In the second phase, the …
