There are currently more than 70 industrial chemicals known to affect female workers' menstruation, such as lead, mercury, arsenic, benzene, toluene, carbon disulfide, gasoline, trichlorethylene, caprolactam, trinitrotoluene, nicotine, etc.
Heavy physical labor and strong noise can also cause irregular menstruation.

Menstrual abnormalities caused by different occupational factors have different manifestations. For example, exposure to benzene and carbon disulfide can easily lead to shortened menstrual cycles and increased menstrual flow; exposure to high concentrations of lead, mercury, and radiation exposure can cause oligomenorrhea; when engaging in heavy physical labor, Dysmenorrhea More common; exposure to noise can cause abnormal menstrual cycles.
