Dr. C. Jerry Lin is professor in the Department of Civil and Environmental Engineering and,
Director of Center for Advances in Water and Air Quality. Dr. Lin has been one of the highest
accorded Lamar faculty member and Dr. Lin is Results-driven leader in air quality. Dr. Lin's
critical analysis on the scientific uncertainties of mercury models which assisted the technical
analysis for national policy making on mercury emission reduction including Clean Air Mercury
Rules (2005), Occupational Mercury Exposure Assessment (2010) and Mercury and Air Toxics
Standards for Power Plants (2011). He is also one of the lead mercury modelers of the United
Nations' Task Force on Hemispheric Transport of Air Pollutants (2010).
“The chemistry of atmospheric mercury: a review (1999)” has been cited 617 times. The
Significance of fate and transport of mercury in transient atmosphere under variant conditions.
This explains the chemical process transforming mercury in atmosphere with its physical and
chemical properties, then identify its transformation with the hindrance of ozone, chlorine,
hydroxyl ions mercury photolysis in atmosphere.
“Dynamic oxidation of gaseous mercury in the Arctic troposphere at polar sunrise (2002)” has
been cited 567 times. Evidence suggests that gaseous elemental mercury is very toxic with long
residual time in atmosphere. If any process which reduces mercury concentration, then it
increases its potential accumulation in troposphere in polar arctic's and which then is released
during sunrise of polar summer.
“Scientific uncertainties in atmospheric mercury models I: Model science evaluation (2006)”
has been cited 224 times. This research investigates the models of transport & deposition of
mercury due to its presence in different phases specially in dry and wet phases. Mercury
chemistry is very uncertain to models and which may compensate to yield a favorable
performance with a model. This research also projects the future uncertainties in models which
needs to be reduced.
His research under international journal ACP, “Estimating mercury emission outflow from East
Asia using CMAQ-Hg(2010)” which is cited 57 times. Mercury & toxic organics are long lived
pollutants in the environment and subject to long-range transport at regional and global scales.
Under appropriate atmospheric conditions, transport of air pollutants from East Asia to North
America takes 7-10 days. Such events can be replicated using atmospheric circulation models
with chemistry describing air dispersion & chemical transformation.
“Observations of atmospheric mercury in China: a critical review(2015)” is cited 52 times. This
was published in Atmospheric Chemistry and Physics (ACP) This study was primarily done
because China is the leading contributor of anthropogenic mercury in atmosphere. This study
was done with ground based measurements at varied geographic locations across China.
