摘　　要：为了解校园空气中NO_2含量的分布及其是否会对师生的健康产生影响,采用功能区布点法在校园内设置具有代表性的采样点,并用短时间采样法采集样品,每个采样点采集10组数据,以盐酸萘乙二胺重氮偶合分光光度法分析样品。结果表明:校园内空气中NO_2含量均低于80.0μg·m^(-3);采用风险基础法进行风险评估,污染物二氧化氮的健康风险HR值小于1,对师生的健康不产生影响。To understand the content distribution of N02 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 NO2 in the air was less than 80. 0 μg·m 3. The risk - based approach was applied for health risk assessment, and the result sugges-ted that the Health Risk （HR） of N02 was less than 1 , which did not affect the health of teachers and students.
