||Air samples for determination of the concentration of Gram-negative bacteria, dust and endotoxin were collected at ten sites in two large pulp and paper mills in Poland. Plant "A" was an older facility while the plant "B" was a modern, fully automated factory with an effective ventilation system. The concentrations of Gram-negative bacteria in the air of examined factories were within a range of 11.0-310.0 cfu/m3, being the highest in plant A at the initial stages of the production cycle consisting of wood chip handling and pulp production. Although Gram-negative bacteria were present in the air of paper mills at relatively low concentrations which never exceeded the value of 1000 cfu/m3 proposed as a safe level, they may have adverse effects on exposed workers, as evidenced by high concentrations of airborne endotoxin and the presence of numerous potentially pathogenic species. Thus, these microorganisms pose a potential risk of respiratory disease for the workers of pulp and paper mills, in particular for those engaged in the handling of wood chips and pulp production.
