Nano Exposure Quantifier
Updated 2026-03-25
The Nano Exposure Quantifier (NEQ) is a quantitative exposure assessment tool designed to to assist users in the safe-by-design process and decisions to reduce risks from working with manufactured nanomaterials (MNs) by following an tiered approach. It provides exposure estimates and guides users to modify their material or process design to reduce exposure and its uncertainty. NEQ is a mechanistic model designed to assess airborne MN exposure in the workplace for particles smaller than 10 µm. A database consisting of 128 MN measurements from 14 exposure studies was used for validation and subsequent calibration of the model.
