title: [Analysis of organic solvent poisonings occurring in Japan from 1995 to 2006].
abstract: OBJECTIVE
  Statistical analyses based on incidence rate were carried out for organic solvent poisonings occurring in Japan.
  
  
  METHODS
  We used the published data of "Typical cases of occupational diseases" and "Current situation of occupational disease occurrence" in the "Industrial Hygiene Guidebook (Roudoueisei no Shiori)". The number of workers as a population of occupational solvent handlers was obtained from the Ministry of Health, Labour and Welfare, Japan.
  
  
  RESULTS
  The annual incidences of solvent poisoning from 1995 to 2006, poisoning, death-by-poisoning, and secondary poisoning were 3.3-5.4, 0.0-0.83, and 0.0-0.34 cases/(100,000 solvent handlers × yr), respectively. Annual incidence classified by manufacturing, construction, and other services were 2.5, 52.0, and 6.1, respectively. Manufacturing showed a small increase from 1999 to 2003, and stopped increasing after 2004. Construction had a peak in 2000. Other services notably decreased from 14.4 in 1999 to 2.5 in 2006. The monthly distribution of the number of poisoning cases was prominent in January. Annual incidences of poisoning, death-by-poisoning, and secondary poisoning were 3.9, 0.5, 0.2 for toluene, 3.5, 0.5, 0.3 for xylene, and 16.4, 4.7, 2.3 for trichloroethylene, respectively.
  
  
  CONCLUSIONS
  The annual incidences classified by industry and solvents showed no change for manufacturing, whereas that for construction notably decreased from 88.6 in 2000 to 12.0 in 2006.
