What we knew at the start Microplastics: Typically refer to solid particles (including fibres) made from synthetic polymers < 5mm in size Secondary MPs formed as larger pieces of `plastic' degrade/abrade Litter (SUPs, fishing gear, bottles, nurdles), synthetic clothing, tyre abrasion Primary MPs in various types of products added for achieving specific functionalities Beads, encapsulates, flakes, powders, crumbs 2 Sector-specific impact assessment Quantities and emissions in scope Alternatives and costs to develop them Other costs (e.g. foreseeable profit losses) Cost/effectiveness ratios (comparing substitution cost vs emissions) Sectors very diverse in terms of substitutability Different restriction proposals for sectors (ban, conditional derogations, mandatory instructions, mandatory reporting, grace periods) 5 Overall proportionality argumentation Use volumes and emissions in scope Effectiveness of emission abatement Marginal abatement cost curve Theoretical considerations 8 Marginal abatement cost curve 10 Further theoretical arguments Option value theory `first act, then learn' rather than `first learn, then act' Builds on the justified assumption that emissions are irreversible we will learn a great deal more about the harmfulness of MPs in the environment in the near term future Option value is net value resulting from the avoidance of irreversible emissions conditional on learning about the actual harmfulness of MPs 11 Conclusions Clear definition of MPs has helped us Early identification of sectors/uses has helped us Providing an analysis of restricting infill material during opinion making was tedious Focus on C/E has made impact assessment comparable across uses Benefits hard to quantify, discussed qualitatively Good to have theoretical arguments that underpin proposed actions but did not get a lot of attention 12

Processed product for water supply and sewerage applications Application :Water supply and sewerage Materials used in the field are PTFE (CAS NO: 9002-84-0), PCTFE (CAS NO: 9002-839), PFA (CAS NO: 26655-00-5), PVDF (CAS NO: 24937-79-9), and ETFE (CAS NO: 94228-79-2).

Fluororesin Products for Manufacturing Processes of paper Lining tank (PTFE), lining piping (PTFE, PFA), lining valve (PTFE, PFA), insertion tube (PTFE, PFA), gasket (PTFE), bellows (PTFE, PFA) Flexible hose (PTFE, PFA), pliable hose (PTFE, PFA) PFAS used in the products is PTFE and PFA, which are polymer materials, and there is no concern about exposure, leakage, or environmental release of eluates.

Aanleiding Tijdens een onderzoek in 2018 naar mogelijke depositie via de lucht van PFOA (perfluoroctaanzuur) en GenX in de omgeving van de fabriek van Chemours (voorheen Dupont) te Dordrecht zijn verhoogde PFOA concentraties aangetroffen in het grondwater en in de bovengrond in de gemeente Molenlanden.
