Mercury (Hg) has proven to be a risk to the public, mainly through the consumption of fish. Because of this, many fish consumption advisories have been issued in Indiana. Although much is known about ...
Quantitative Evaluation of Real-time Measurements of Atmospheric Mercury in a Mercury- contaminated Area
Mercury Atmosphere Real-time measurement C ontaminated s ites
2013/9/29
On-site real-time measurements may be one of the most useful methods to estimate Hg pollution levels at mercury-contaminated sites. However, there are very few reports that estimate the reliability of...
