Gaseous and particulate mercury in the atmosphere was collected simultaneously at ten sampling stations which located northwest of Niigata Plain at selected twelve days in 1981 and 1982. Gaseous mercury was collected on gold coated Chromosorb P, while particulate mercury was on quartz fiber filter. Both were determined by flameless atomic absorption spectrophotometry with a combution-gold trapping-heat vaporization procedure. The gaseous mercury concentration obtained in this region ranged from 1.3 to 11 ng/m3 with a median 3.1 ng/m3, which agreed well with the reported background concentrations. There was no large variations between daytime and nightime, and among sampling stations with respect to the gaseous mercury concentration. While the particulate mercury concentration ranged from 0.006 to 1.6 ng/m3 with a median 0.026 ng/m3. It was detected that the particulate mercury concentration significantly rise as according to the elevation of the gaseous mercury concentration. The ratio of particulate mercury to gaseous mercury at background level ranged from 0.15×10-2 to 23×10-2 with a median 0.86×10-2.
