FHERITALE Webinar: The Impact of Nano and Microplastics on Health, Food, and Environment

• 0:01 Introduction (Antonio Rosato): The webinar is organized by the FHERITALE project, a coordination and support action involving European research infrastructures in food, health, and environment.

• 0:47 FHERITALE Project Overview: The project aims to provide an overview of services offered by European infrastructures to address challenges posed by artificial materials (especially micro/nanoplastics) released into the environment.

• 2:43 Project Goals: Identify available services, research priorities, gaps in current services, and provide guidelines for future developments.

• 5:44 Speaker 1: Silvia Orlandini (ICAR): Focuses on the standardization process, particularly ISO standards, and their importance for research and legislation in the dairy sector.

• 7:41 ICAR Introduction: The International Committee for Animal Recording provides standardized language for sustainable animal production, including guidelines and certifications.

• 9:43 ICAR & ISO Collaboration: ICAR develops guidelines that can be endorsed as ISO standards due to strong collaboration with ISO committees.

• 11:50 ICAR's Role in Standardization: Participates in various ISO technical committees, providing expertise and contributing to the development of standards.

• 12:04 Importance of ISO Standards: Provides consensus-based standards, standardized terminology, and can be used for legal purposes, ensuring consumer protection and market facilitation.

• 16:53 ISO Standard Development Process: Involves a severe, well-controlled voting system to ensure consensus and can take at least three years.

• 23:50 ISO Standards & Validation: ISO standards requires validations through interlaboratory studies.

• 33:09 Speaker 2: Alba Hernandez (Plasticheal): Focuses on the connection between micro/nanoplastics and human health, presenting research from the Plasticheal project.

• 35:19 Micro/Nanoplastics Definition: Nanoplastics are defined as those below one micron, as they can translocate body barriers and accumulate in secondary organs.

• 36:12 Nanoplastics Internalization: Studies show nanoplastics can be easily internalized by cells in respiratory and gastrointestinal barriers, blood vessel walls, and blood cells.

• 38:08 Toxicological Potential: High surface area of nanoplastics poses a potential toxicological risk due to interactions with cellular components.

• 39:33 Key Questions: What is in our bodies and what risk do specific amounts pose.

• 40:04 Challenges in Research: Lack of validated analytical procedures for measuring micro/nanoplastics in various matrices and lack of representative materials for hazard assessment.

• 41:49 Plasticheal Project Efforts: Develops analytical methodologies and representative materials (beyond polystyrene) to better measure exposure and effects.

• 43:37 Exposure Studies: Found significant levels of micro/nanoplastics in air, water, foods, and biological samples from workers in textile and recycling industries.

• 44:34 Effects Studies: Nanoplastics can induce genotoxicity, alter microbiome composition, cause immune dysfunction, and potentially have carcinogenic effects in long-term exposure.

• 50:07 Remaining Unknowns: Many questions remain, particularly regarding effects at doses relevant to human exposure.

• 53:41 Speaker 3: Gabriela Kalčikova (Planterastics): Focuses on the environmental impact of microplastics, including sources, transport, aging, and interactions with other pollutants and biota.

• 54:16 Sources of Microplastics: Diverse sources, including plastic fragmentation, laundry fibers, tire wear, and synthetic paints, contribute to microplastic pollution.

• 56:06 Transport of Microplastics: Transport occurs through soil, water, and air, with air being a major pathway for long-distance transport to remote locations.

• 58:20 Aging of Microplastics: Undergo abiotic (UV, mechanical) and biotic (biofouling) aging, changing their properties and interactions.

• 1:00:02 Biofouling: Biofilm formation on microplastics alters density, aggregation, and absorption properties, potentially influencing transport and toxicity.

• 1:03:14 Co-transport: Microplastics can act as carriers for microorganisms and other pollutants.

• 1:06:05 Interactions with Biota: Microplastics interact with various organisms, causing mechanical and chemical effects, including ingestion, disruption of membranes, and leaching of additives.

• 1:11:00 Trophic Transfer: Microplastics can be transferred through the food chain, even if they don't directly affect the initial organism.

• 1:11:52 Conclusion: The topic is complex, with variability and interactions affecting the fate, transport, and ecotoxicological effects of microplastics.

• 1:12:07 Particle characteristics: It is crucial to use and fully describe relevant plastic types. Spherical polysterene particles are a poor representation of enviromental microplastics.

• 1:14:10 General Discussion: Several questions and comments were discussed.

• 1:35:23 Infrastructure Capabilities: There is a need for a better-organized network and increased capacity for producing and characterizing environmentally relevant microplastics.
