To understand the hazards of urea dust on humans, a survey of 71 workers exposed to urea dust for a long time was conducted. Of the 71 respondents, 64 were male and 7 were female, with an average age of 26.7 ± 4.1 years and working dust exposure of 0.5-6 years. The control group chose the factory without urea dust exposure history, other conditions similar to the contact group of 33 workers. Determination of urea concentration on the spot, exceeding the national maximum allowable concentration of various other dust (10mg / m ~ 3) 2 ~ 1,400 times.
