Abstract：The content of lead in 135 ginkgo biloba leaves in Chengdu was determined by flame atomic absorption spectrometry. The quality control of the inspection process was carried out by adding standard to each sample for recovery. The lead content in the main roads of East Gate，South Gate，West Gate and North Gate is higher than that of Ginkgo biloba leaves in the park（P
