KTMB-Nov22-RiverWalk-3-2Join Dr. Monica Arienzo of the Desert Research Institute (DRI) and myself for a fall River Walk on November 5th at 10:00 a.m. The event will be hosted by Keep Truckee Meadows Beautiful. We will walk along the beautiful Truckee River, talk about microplastics and their prevalence in the Truckee Meadows, and highlight some of the exciting microplastics research taking place at DRI and UNR. Be sure to sign up for the event before the slots fill up!

This month my collaborators and I will be presenting our research at the 14th International Conference on Mercury as a Global Pollutant.

Talks will include:

  • Testing methods for quantification and identification of reactive mercury compounds
  • Development of an automated method for measurement of gaseous oxidized mercury
  • Measurement and understanding GOM concentrations and chemistry from sites in Utah, Hawaii, Maryland, and Nevada, USA
  • An integrated system for accurate, independently verified measurements of oxidized mercury
  • Reactive mercury speciation and dry deposition during AMDEs in the Arctic

Posters will include:

  • Mercury is a global contaminant in commercial cat and dog foods
  • Introducing UNRRMAS­­ 2.0: Improvements for quantification and identification of atmospheric reactive mercury
  • Ozone may not be an important oxidant of atmospheric mercury
