From: Plastics in biota: technological readiness level of current methodologies
Overview of techniques for sample collection (left) and sample preparation (right) of plastics in fish, bivalves and non-bivalve invertebrates. For the sample preparation, the reported percentage for the different types of digestion was based on analytical methods including digestion only and digestion in combination with a density separation. For each type of digestion, the most common chemical is reported as well as the range in which it is applied for the different biota subgroups. Techniques with less than 10 occurrences are grouped as others
