Continuous Monitoring of Mercury Concentration in Air
In Japan, a pilot project for the continuous monitoring of mercury in air was first conducted in February 2007 at the Cape Hedo Aerosol and Atmosphere Monitoring Station (CHAAMS) in Okinawa Prefecture using a specially designed Hg monitor. This was followed by the commencement of continuous monitoring in October of the same year up to the present (see Fig. 21 and Fig. 22).
This project aims at contributing to the following matters.
Monitoring of the concentration of mercury and other heavy metals contained in air, particles and precipitation
Acquisition of useful information on the long range transport of trace elements in the Asia-Pacific Region
Establishment of monitoring technologies
International cooperation for monitoring of the atmospheric environment
