【摘要】Objective To establish a method for the determination of dimethylformamide(DMF) and investigate dermal contamination and absorption among workers occupationally exposed to DMF. Method 37 workers exposed to DMF were divided randomly into two groups. DMF was washed down by isopropyl alcohol in A group (16 workers) and water in B group(21 workers).Gas chromatography was used for the quantification of dermal contamination and N-methylformamide(NMF) in urine, correlative study was done between them. Results DMF could be detected in all samples in A group, but could not be detected in B group. The miscel-laneous peaks could be completely separated from the DMF peak in the sample spectrum, without matual in-ference. The highest degree of total dermal contamination was observed in wet spinning

workshop[(2.50±0.95) mg] and dry spinning workshop[( 1.95±0.61) mg] were lower. The respiratory cumulative exposure dosages were 351.3, 201.3 and 135.2 mg respectively. The average DMP concentration in air of the third printing processing workshop, the dry spirning workshop and the wet spinning workshop was 60.2, 89.6, 156.4 mg/m3
