Qualitative analysis was conducted on the organic solvents used by enterprises in their production processes, and the detection results of 1, 2-DCE were statistically analyzed.Results:A total of 88 organic solvent samples were collected, with a qualitative detection rate of 21.6% (19/88) for 1, 2-DCE. A total of 30 enterprises using organic solvents were surveyed and tested, with an enterprise detection rate of 36.7% (11/30) for 1, 2-DCE. The workplace exceedance rate for 1, 2-DCE was 37.0% (34/92), and the post exceedance rate was 15.4% (4/26) .Conclusion:The degree of occupational exposure hazard related to 1, 2-DCE remains severe.
