The European Chemicals Agency (ECHA) has commissioned, as part of the activities of the European Union (EU) Observatory for Nanomaterials (EUON), a study on the collection and review of information on nanomaterial-based and nano-enabled plant protection products, biocidal products, and fertilizing products. The study includes a systematic literature and documentary review on nanoforms of (active) substances and delivery systems of the corresponding formulations used in biocidal products, plant protection products, and/or fertilizing products. The study also involves the collection of information from key stakeholders across the EU (and beyond) through questionnaires and interviews. The survey will close February 29, 2024, at 18:00 (CET).
