Monitoring atmospheric mercury using deciduous leaves
MetadataShow full item record
Atmospheric mercury can be a significant source of mercury to water and land areas relatively uncontaminated by the heavy metal. In this study, mercury concentrations were determined in air at various temperatures from December 2013 through July 2015. Air concentrations measured range from 1.905 ng m-3 at 34 oC to 0.0515 ng m-3 at -15 oC. The correlation of atmospheric mercury concentrations with temperature resulted in an equation with an R2 value of 0.8 indicating that the line fits the data well. The equation developed here was used to estimate atmospheric mercury concentrations on days leaf ...
