| 中文摘要: |
| 2015—2016年在郑州市8个行政区布设80个采样点，监测分析气态元素汞（GEM）浓度分布特征。结果表明，郑州市GEM小时平均质量浓度范围为2.50 ng/m3～17.4 ng/m3，平均值为（8.91±1.68）ng/m3；日间GEM浓度高于夜间，12:00—15:00达到最高值，早晨降至最低值；四季GEM平均浓度由高到低为冬季＞春季＞秋季＞夏季；8个行政区的GEM平均浓度由高到低为金水区＞郑东新区＞经开区＞高新区＞管城回族区＞惠济区＞中原区＞二七区；不同功能区GEM平均浓度由高到低为工业区＞交通区＞商业区＞高教区＞行政区＞住宅区。 |
| 英文摘要: |
| 80 sampling sites were set in eight districts of Zhengzhou for analyzing the distribution of gaseous elemental mercury(GEM) concentration from 2015 to 2016. Results showed that the hourly average of GEM concentrations in Zhengzhou were between 2.50 ng/m3 and 17.4 ng/m3, the mean concentration was （8.91±1.68）ng/m3. The GEM concentration in daytime was higher than that at night, the peak hours were through 12:00 to 15:00, the minimum appeared in the morning. The GEM mean concentration in the four seasons was sorted from highest to lowest as winter＞spring＞fall＞summer， while in the 8 districts, it was sorted as Jinshui district＞Zhengdong new district＞national economic and technological development zone＞national hi tech industrial development zone＞Guancheng district＞Huiji district＞Zhongyuan district＞Erqi district. In different functional zone, the mean concentration was sorted as industrial area＞traffic area＞commercial area＞higher education area＞administrative area＞residential area. |
