| 内容記述 | Atmospheric gaseous mercury (AGM) and atmospheric particulate mercury (APM) concentrations were both measured approximately in the same duration, i.e., from August 2008 to September 2009.These measurements were acquired on the rooftop of the North Building of the Niigata Institute of Technology (NIIT) located in Fujihashi, Kashiwazaki City.AGM was also measured from December 2008 to April 2009 on the sixth-floor porch of a residence building in Honami-cho, Kashiwazaki City, which is located approximately 4 km north of NIIT.The obtained median concentrations of AGM at NIIT and Honami-cho were 1.77 ng/m^3 and 1.62 ng/m^3, respectively, both of which were less than 1/20 of the guideline concentration (40 ng/m^3) for reducing risks due to long-term exposure to atmospheric mercury.The median concentrations of AGM in the daytime and nighttime at NIIT were 1.89 ng/m^3 and 1.71 ng/m^3, respectively.The reason behind this concentration difference may be because anthropogenic mercury emission sources to the atmosphere in Kashiwazaki City influence AGM more in the daytime than in the\nnighttime. The median concentration of APM was 0.0094 ng/m^3, which was nearly 0.5% of the AGM concentration.Significant correlations were observed between APM and the water-soluble nitrate and calcium in the particulate matter. | |||||||||
