Abstract In parallel with the development of novel materials, such as cellulose nanofibers (CNFs), their effects on aquatic organisms should be evaluated. In ecotoxicity testing, concentration measurements are important to obtain accurate exposure co

The phenol-sulfuric acid (PSA) method is a widely used colorimetric method for determining the total saccharides, which is simple and rapid. Microplate-based PSA methods have been developed to handle a large number of samples and reduce the use of ha

We evaluated the occupational exposure of cellulose nanofibers (CNFs) at a production facility during 1) the collection of CNF powder produced by drying CNF slurry and 2) the transfer of CNF powder from a large bag to small bags. Airborne CNFs in the
