To understand the content distribution of NO_2 in our campus,and whether it would influence the health of teachers and students,the functional regionalization method was applied to set representative sampling points in campus. The short-time sampling method was applied to gather samples,in which 10 groups of data at each sampling point were collected. The data was analyzed by the theory of N-(1-napthyl) ethylenediamine hydrochloride diazo-coupling spectrophotometric. The results show that the concentration of NO_2 in the air was less than 80. 0 μg·m~(-3). The risk-based approach was applied for health risk assessment,and the result suggested that the Health Risk( HR) of NO_2 was less than 1,which did not affect the health of teachers and students.
