Methods By using the declaration system of occupational disease hazards in Tianjin,we collected the information on enterprises that have been declared and reviewed from January to December 2022,and organize and analyze the distribution of occupational disease hazards. Results As of 2022,a total of 5 344 enterprises in Tianjin City had completed the application and passed the review,243 340 people（31.69%） were exposed to occupational hazard factors. The damaged population was mainly concentrated in the five districts in the outer suburbs（44.82%）,small enterprises（54.08%）,and domestic enterprises（31.82%）. In cases which the hazardous factors of the enterprise exceed the standard,the highest exceedance rate was noise（10.78%）,followed by high temperature（5.76%）. There were significant differences in the exposure rate,detection rate and health examination implementation rate between different regions,enterprise scales,economic types and industries（all P<0.01）.
