“…58 For this matrix in particular, it is vital that accurate blank concentrations as well as recoveries are reported so that researchers and managers can best understand and limit the risk to the public. 72 Depending on the complexity of the matrix and the size of the particles being analyzed, the required sample volume will vary. Preliminary samples should be collected to obtain an estimate of particle size distribution and counts per liter.…”

“…company. The polymer types polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC), which were investigated in this study, account for > 60% of the global plastic production volume [50] and a high share of the MP particles typically detected in aquatic environments [51][52][53]. Despite a market share < 3% [50], acrylonitrile butadiene styrene (ABS) was also investigated as a representative of styrene copolymers, since > 40% of plastics in electrotechnical waste are assigned to it [54,55].…”

The presence of microplastic (MP) particles in aquatic environments raised concern about possible enrichment of organic and inorganic pollutants due to their specific surface and chemical properties. In particular the role of metals within this context is still poorly understood. Therefore, the aim of this work was to develop a fully validated acid digestion protocol for metal analysis in different polymers, which is a prerequisite to study such interactions. The proposed digestion protocol was validated using six different certified reference materials in the microplastic size range consisting of polyethylene, polypropylene, acrylonitrile butadiene styrene and polyvinyl chloride. As ICP-MS/MS enabled time-efficient, sensitive and robust analysis of 56 metals in one measurement, the method was suitable to provide mass fractions for a multitude of other elements beside the certified ones (As, Cd, Cr, Hg, Pb, Sb, Sn and Zn). Three different microwaves, different acid mixtures as well as different temperatures in combination with different hold times were tested for optimization purposes. With the exception of Cr in acrylonitrile butadiene styrene, recovery rates obtained using the optimized protocol for all six certified reference materials fell within a range from 95.9% ± 2.7% to 112% ± 7%. Subsequent optimization further enhanced both precision and recoveries ranging from 103% ± 5% to 107 ± 4% (U; k = 2 (n = 3)) for all certified metals (incl. Cr) in acrylonitrile butadiene styrene. The results clearly show the analytical challenges that come along with metal analysis in chemically resistant plastics. Addressing specific analysis tools for different sorption scenarios and processes as well as the underlying kinetics was beyond this study's scope. However, the future application of the two recommended thoroughly validated total acid digestion protocols as a first step in the direction of harmonization of metal analysis in/on MP will enhance the significance and comparability of the generated data. It will contribute to a better understanding of the role of MP as vector for trace metals in the environment.

“…There are currently no standardised and unambiguous methods for sampling MPs in the various environmental matrices, even if a lot of work has been done 30,31,32,33,34 . In such a complex scenario, it is necessary to know the matrix to be monitored and to carry out the proper sampling.…”

Trillions of tiny particles generated by our plastic-reliant society are polluting environments worldwide. An explosion of research has been devoted in the last years to detect, identify and quantify the microplastics, hidden not only in the oceans but also in the world's rivers, lakes, air, soil as well as food and organisms. Thus, we urgently need reliable standards to support the decision-maker to handle many issues related to this question. In this paper, the results of a VAMAS survey that involved 390 experts are presented and discussed. The inter-laboratory studies urgently needed in the next future are proposed.
