Title Emissions of chemical compounds and bioaerosols during the secondary treatment of paper mill effluents

Abstract Measurements were taken in summer in 11 Canadian paper mills during a 2- to 3-day period in each mill and identified and quantified the main chemical compounds and the bioaerosols emitted during the biological treatment of paper mill effluents. Sulfur compounds had the highest concentrations in the air. Next were the carbon and nitrogen oxides, ammonia, some organic acids and terpenes, which come from wood. Odour perception thresholds for most of these substances are much lower than those established to protect the health of workers. Gram-negative bacteria were high at only one site, whereas the mould Aspergillus fumigatus was occasionally present at low concentration. The highest concentrations were measured where there was water or dust aerosolization. Emissions are managed by controlling the operations that lead to the dispersion of water and particles into the air and through the wearing of personal protective equipment. Stringent personal hygiene measures remain the best means of prevention for bioaerosols.
