| Abstract |
Personal exposure measurements were collected for 46 job titles at a bleached-kraft pulp mill. Overall results indicated low levels of exposure with a few exceptions. Although chlorine dioxide was the exclusive bleaching agent, area samples indicated that chlorine, not chlorine dioxide, was present in all areas except the chemical preparation area and during a pulp spill. The highest shift-long exposures to chlorine were measured in the chip yard and were attributed to uncontrolled stack emissions. Wood dust samples collected from several labourers significantly exceeded regulatory limits. Results from data-logging equipment in the chemical preparation area showed several peak exposures to chlorine dioxide that exceeded the short-term exposure limit. The peaks were correlated with tasks and upset conditions and could not have been detected using shift-long average-based sampling devices. Data-logging instruments are necessary to characterize exposures in the pulp and paper industry. Topics: air sampling; bleaching; chlorine dioxide; calcium oxide; carbon monoxide; hydrogen sulfide; electrochemical gas sensors; exposure evaluation; harmful substances; job-exposure relation; occupational health survey; personal sampling; pulp and paper industry; pulp refiners; short-term exposure; wood dust. |
