This report aims to compile relevant regulatory documents to provide an overview on (I)the current practices in European regulatory frameworks for non-natural polymers ingeneral; and (II) review the current state of nano- and microplasticriskassessmentaccording to ongoing research activities. The formation of microplastic particles from larger polymer items is considered aninherent property of most artificial polymers. Currently, polymers are exempted fromregistration under REACH. However, the registration of selected polymers is anticipatedand concepts such as the Polymers of Low Concern (PLC) and the Polymers RequiringRegistration (PRR) concept are under consideration to allow scientifically soundjustifications for selecting polymers that will require registration. In that regard, criteriadescribing the physical and chemical properties relevant for risk assessment have beenformulated. However, primary as well as secondary nano- and microplastic particles arecurrently not considered explicitly in regulatory frameworks. In addition, risk assessment strategies specifically for nano and microplastic have beenproposed by several scientists. These approaches are summarized here and put into thecontext of WP4goalsand the work conducted in the experimental WPs. This report shows also the need for progress in our scientific understanding to clarifythe connection betweenphysico-chemical properties and potential hazardous effects ofpolymers, andidentify the potential for read-across from pristine materials used inlaboratory testing to the weathered or aged material found in the environment thathumans are ultimately exposed to. In addition, new EU initiatives fostering thedevelopment of restriction and mitigation measures to reduce plastic use and preventplastic product release into the environment are highlighted, such as the EU PlasticsStrategy or the Towards zero pollution action plan, as part of the EU Green Deal (seealso D6.3). This overview on the current regulatory situation provides a starting point and basis forthe work planned within WP4, specifically for the development of an integrated riskassessment strategy for human and environmental health within T4.1 and T4.2. |
