Atmospheric gaseous mercury in Northern Taiwan.
The first attempt to systematically investigate the atmospheric mercury over the territory of Taiwan has been undertaken. Four sampling sites were selected in localities qualified as urban, suburban, industrial-rural and rural ones, within the northern part of Taiwan. The sites were monitored for atmospheric gaseous mercury alternately from September to December 2003 and from April to June 2004, by using a portable automated mercury analyzer Model Gardis-3. The results have shown rather high atmospheric gaseous mercury levels (up to 30 ng/m3 at the urban site, up to 22 ng/m3 at the rural site, up to 24 ng/m3 at the industrial-rural site, and up to 90 ng/m3 at the suburban site) which may indicate the presence of considerably strong point and area mercury sources whose origin still has to be detected more precisely.
