متن کاملAssessing the Comparability of Ammonium, Nitrate and Sulfate Concentrations Measured by Three Air Quality Monitoring Networks
Airborne fine particulate matter across the United States is monitored by different networks, the three prevalent ones presently being the Clean Air Status and Trend Network (CASTNet), the Interagency Monitoring of PROtected Visual Environment Network (IMPROVE) and the Speciation and Trend Network (STN). If combined, these three networks provide speciated fine particulate data at several hundre...
متن کاملNitrate transport and ammonium-nitrate interactions at high nitrate concentrations and low temperature
The unplications of the operation of biphasic nitrate transport and the effects of low temperature incubations on phytoplankton N-physiology are discussed. The inclusion of 2 nitrate transport systems (low rate, high affinity; high rate, low affinity) with different regulatory thresholds and temperature-dependent steps can be included readily in the structure of existing mechanistic models of N...
متن کاملExcimer laser fragmentation-fluorescence spectroscopy as a method for monitoring ammonium nitrate and ammonium sulfate particles.
Excimer laser fragmentation-fluorescence spectroscopy (ELFFS) is shown to be an effective detection strategy for ammonium nitrate and ammonium sulfate particles at atmospheric pressure and room temperature. Following photofragmentation of the ammonium salt particle, fluorescence of the NH fragment is observed at 336 nm. The fluorescence signal is shown to depend linearly on particle surface are...
