Study of Atmospheric Gaseous Mercury in Taiwan

摘要

The first attempt to systematically investigate the atmospheric mercury over the territory of Taiwan has been undertaken. Six sampling sites were selected in localities, which can be characterized as suburban, industrial-rural and rural, within the Northern part of Taiwan. The sites were monitored for TGM alternately from September 2003 until April 2004, by using a portable automated mercury analyzer Model Gardis-3. The results have shown rather high atmospheric TGM levels (up to 30 ng/m3 at rural sites and up to 80 ng/m3 at the suburban site) which may indicate the presence of considerably strong point and area mercury sources which origin still has to be detected more precisely.
