| Abstract: | The content of Fe, Zn, Mn, Cu and Cd in Ginkgo leaves were determined by flame atomic absorption spectrometry. In this experiment, the content of five microelements including Fe, Zn,Mn ,Cu and Cd （μg/g） was 394.2,22.4,12.7,8.5,5.4 respectively in the sample collected from campus of Bengbu College; 198. 9,24. 7,10.8,9.2,6. 1 respectively in Long-zi Lake Park; 395. 6, 32.5,23.4,18.9,18.9 respectively in Zhu Park. The recoveries were between 97.8 and 102.1 ,The content of five elements was Fe〉Zn〉Mn〉Cu〉Cd in the same samples,and the content was higher in Zhu Park than others. |
