摘要：

Tropospheric ozone samples collected during a twelve-month period in urban air show an enrichment of about 9% in the heavy isotope O-50(3) consistent with predictions from laboratory measurements. The enhancement of about 7% observed in O-49(3) is still within the uncertainty of the expected value. These measurements confirm that the isotope effect, repeatedly found in laboratory experiments, is also produced in the atmosphere during the ozone formation process.
