title: [Analysis of workers' exposure to dust in various chemical industry plants based on measurements conducted by work environment reseach laboratories in Poland in 2001-2005].
abstract: BACKGROUND
  The aim of this publication is to present the results of a detailed analysis of dust exposure in the production and processing of chemical substances, including the kind of produced materials, workposts and type of emitted dusts.
  
  
  METHODS
  Data on dust exposure were based on measurements of dust concentrations performed by industrial hygiene laboratories. Their results were obtained from sanitary and epidemiological stations operating throughout Poland. Average concentrations ofinhalable and respirable dust at specific workposts in the chemical industry (including 7 groups) were calculated and the percentage of surveys exceeding hygiene standards was estimated.
  
  
  RESULTS
  The analysis included 2800 results of dust concentration measurements. The highest concentrations of inhalable and respirable dust (containing a few percent of silica) and the highest percentage of the results above hygiene standards were observed in the manufacture of basic chemicals The concentration of inhalable dust in this group was 2.83 mg/m3, and the percentage of measurements above hygiene standards--16.57%, while for respirable dust, these values were respectively 0.75 mg/m3 and 27.32%.
  
  
  CONCLUSIONS
  Exposure to dust in the chemical industry differs, depending on the type of production. Particularly high concentrations, very often above hygiene standards, were observed in factories manufacturing basic chemicals.
