o Leader/Deputy Leader: - Dr Andrea Mario Giovannozzi (IT) - Dr Bert van Bavel (NO) o Objectives: - To have a global vision of MNP related existing/upcoming EU R&D programmes, scientific activities through publications, standardisation/harmonisation activities and potential/draft legislations for MNP monitoring in food (drinking and bottled water) and environmental water (river and wastewater) matrices that cover sampling, sample preparation, analysis equipment or technologies, reference materials, interlaboratory testing, toxicological studies and risk assessment. - To provide guidance and ensure coherence of ICPLASTIC streams with these programmes. - Create a network of informed and trained scientific experts o Feed: - http://instagram.com/tags/ICPLASTIC_WG1

o Leader/Deputy Leader: - Dr Christoph Krafft (DE) - Dr Tomasz Runka (PL) o Objectives: - To optimize and harmonize MNP analytical equipment and protocols so that, either individually, or combined, when in conjunction with optimised sampling and sample preparation equipment and protocols (WG4), via WG5, end user and design specifications are compatible with the ICPLASTIC risk analysis and the ISO standards when determining number, mass, shape, size distribution ranges and chemical identity of MNPs. In doing so it will attempt to elucidate: Which parameter and output data are needed for which purpose and how can they be obtained in a robust and reproducible way? o Feed: - http://instagram.com/tags/ICPLASTIC_WG2

o Leader/Deputy Leader: - Dr Roberto Alamino (UK) - Dr Maria Chli (UK) o Objectives: - To identify where ML can be implemented in WGs 2 and 4 to decrease the time and cost to obtain reliable and comparable MNP analytical data through optimising: · potentially sampling and sample preparation · particle selection for analysis by micro-spectroscopy techniques · interpretation of multi- or hyperspectral imaging data from micro-spectroscopy techniques · interpretation of pyrograms from thermal desorption pyrolysis. o Feed: - http://instagram.com/tags/ICPLASTIC_WG3

o Leader/Deputy Leader: - Dr. Laura Rodriguez Lorenzo (P) - Dr. Ott Scheller (EE) o Objectives: - To optimize and harmonize MNP sampling and sample preparation equipment and protocols so that, when in conjunction with their analytical analogues from WG2, end user and design specifications are compatible with the ICPLASTIC risk analysis and the ISO standards when determining number, mass, shape, size distribution ranges and chemical identity of MNPs. o Feed: - http://instagram.com/tags/ICPLASTIC_WG4

o Leader/Deputy Leader: - Prof. Jes Vollertsen (DK) - Dr Andy Booth (NO) o Objectives: - To act as a data hub to ensure that data on relevant particle mass, shape and size distribution ranges, and chemical identity, originating from each of the WGs 2, 4, 6 and 7 are communicated to each other to adjust their scope as necessary. o Feed: - http://instagram.com/tags/ICPLASTIC_WG5

o Leader/Deputy Leader: - Dr Patricia Taladriz Blanco (CH) - Dr Barbara Rothen-Rutishauser (CH) o Objectives: - Take into consideration the ever-evolving relevant particle mass, shape and size distribution ranges, and chemicals from WG5 to perform toxicological studies with their results fed back into WG5 and for a risk analysis to be done in WG7. o Feed: - http://instagram.com/tags/ICPLASTIC_WG6

o Leader/Deputy Leader: - Dr Manosij Ghosh (B) - Dr Ivana Guševac Stojanović (RS) o Objectives: - A risk analysis of relevant MNPs will be performed from WG6 results to further optimise end user and design specifications for MNP sampling, sample preparation protocols and equipment in WG2 and WG4 and formulate a roadmap for new MNP legislation (deliverable 20) that will include the application for a COST Innovators Grant. o Feed: http://instagram.com/tags/ICPLASTIC_WG7
