This study examined mercury (Hg) emissions from cement manufacturing facilities in Korea. Hg concentrations in stack gases from a kiln at the largest cement manufacturing facility (CMF) in Korea were measured using three different methods: a wet-chemical method and on-line measurements with two different types of conversion systems (SnCl 2 > and thermal) attached in front of each analyzer.

The natural mercury emissions were estimated from selected natural sources by the dynamic flux chamber technique. The results indicated that the anthropogenic mercury emissions totaled approximately 8.85 tons (t), more than 50% of this total originated in coal combustion and 23.7% of this total emission in the industrial process (include cement ...
