[Objective] To explore the incidence of occupational chronic benzene and its compounds, the relationship between poisoning time and seniority and age. [Method] To study the relationship between the onset time of occupational chronic poisoning cases and the age of onset, onset time and length of service in Fujian province from June 1996 to February 2000. [Results] The average age of onset of patients was (2.512 ± 7.41) years, the average length of service (2.5 ± 4.06) years. The age of onset of patients in state-owned enterprises was significantly different from that of foreign-funded enterprises and township enterprises. However, there was a very significant difference in the length of service between the two groups. [Conclusions] Workers under the age of 2 and under 6 years of age who take drugs within 1 year should be regarded as the key population for occupational health supervision. Foreign-funded enterprises and township enterprises should be the focus of occupational health supervision in our province.
