Title Personal exposures to inorganic and organic dust in manual harvest of California citrus and table grapes
Bibliographic information Aug. 2004, Vol.1, No.8, p.505-514. Illus. 25 ref.
Abstract The aim of this study was to evaluate the exposure to inorganic and organic dust during manual harvest operations of citrus fruit and table grapes. Personal exposures to inhalable dust and respirable dust were measured five times over the 4-month harvesting season. Dust samples for analysed mineralogy, respirable quartz, endotoxins and microorganisms. Exposures for citrus harvest had geometric means of 39mg/m3 for inhalable dust and 1.14mg/m3 for respirable dust. These exposures were significantly higher than those for table grape operations and exceeded the threshold limit value for inhalable dust and respirable quartz. Considered independently, these exposures may be high enough to cause respiratory health effects. However, exposures for table grape operations were lower than the threshold limit value, except inhalable dust exposure during leaf pulling.
