Welcome!

The “Webinar #2 on Micro-/Nanoplastics” took place on 28 March 2025, from 2:00 - 3:30 p.m. CET (9:00 - 10:30 a.m. EDT).

This webinar covered the current trends of microplastic pollution in marine environment, and risk assessment of microplastics.

This webinar is part of UNITAR’s ongoing series on the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), which has been running over the past several years. The focus of this session is on updates and revisions to the GHS text, a topic that has come up in discussions with partners and stakeholders.

UNITAR developed the 2024-2025 PCB Webinar Series to raise awareness and enhance global and national capacities towards the environmentally sound management of PCB.

The dramatic growth in chemical production and trade during the past decades has raised concerns about the potential risks posed by hazardous chemicals and pesticides. Countries lacking adequate infrastructure to monitor the import and use of these chemicals are particularly vulnerable.

This fourth webinar in the series of IOMC webinars on the Global Framework on Chemicals (GFC) Implementation Programmes focuses on “Developing a GFC Implementation Programme on Strengthening National Chemicals Legislation and Institutional Capacities”.

Les systèmes de classification et de communication des risques chimiques sont des éléments clés de la gestion rationnelle des produits chimiques. Pour harmoniser ces systèmes à l’échelle mondiale, les Nations Unies ont adopté, en 2003, le Système général harmonisé de classification et d’étiquetage des produits chimiques (SGH).
