Health-based nanomaterial guidance value (HNGV) for occupational exposure to spheroidal biodurable engineered nanomaterials of relatively low substance-specific toxicity
Exposure to engineered nanomaterials (ENMs) at the workplace can adversely affect human health via inhalation. Occupational exposure limits (OELs) for specific ENMs remain scarce due to a lack of nano-specific data and consensus on the most appropriate dose metric for exposure assessment. In 2022, recommendations were provided on how to derive Health-based Nano Reference Values (HNRVs) for differe
