Occupational asthma from low level exposure to pure cellulose, implications for the paper and cardboard industries?

This is a detailed report of occupational asthma confirmed by SIC and Oasys PEF analysis with exposure to ozone bleached cellulose at low concentrations. A search for protein contaminants and specific IgE were all negative. Cellulose is a polysaccharide derived from wood, mostly pine species. This case has significant implications for others with occupational asthma from paper and cardboard dust, where symptomatic occupational asthma occurs but a specific cause has not been identified.
