Determination of the Distribution of NO2, CO, and PM2.5 Concentration Using a Photochemical Model of Air Pollution: Case Study of Tehran City
Background and objectives: Tehran is one of the most polluted cities in the world in terms of air pollution. Modeling is a useful tool in air pollution management. The objectives of this study are to determine the distribution of the main air pollutants concentration in Tehran and to construct a photochemical model appropriate to the geography and natural characteristics of Tehran. Methods: I...
متن کاملParticipation of the Halogens in Photochemical Reactions in Natural and Treated Waters.
Halide ions are ubiquitous in natural waters and wastewaters. Halogens play an important and complex role in environmental photochemical processes and in reactions taking place during photochemical water treatment. While inert to solar wavelengths, halides can be converted into radical and non-radical reactive halogen species (RHS) by sensitized photolysis and by reactions with secondary reacti...
متن کاملReview on carbon nanotubes and carbon nanotube bundles for gas/ion separation and water purification studied by molecular dynamics simulation
Water and air pollutants have huge impacts on the entire living system. In addition, the newly emerging nanopollutants, increasing global warming, and consequent climate changes are posing major threats to the freshwater or fresh air availability. This has made it urgent to invent an appropriate water/air treatment technology that removes nanopollutants and also desalinates water to a significa...
متن کاملModeling Turbulent Entrainment of Air at a Free Surface
Overview In free-surface flows the turbulence in the liquid may be sufficient to disturb the surface to the point of entraining air into the flow. This process is important, for example, in water treatment where air is needed to sustain microorganisms for water purification and in rivers and streams for sustaining a healthy fish population. Air entrainment is typically engineered into spillways...
متن کاملتاثیر همزیستی قارچ اندوفیت بر برخی شاخصهای فیزیولوژیک گیاه گوجه‌فرنگی تحت تنش شوری 10 روزه
The influence of endophyte fungus piriformospora indica on characteristics of the growth, water status, photosynthetic pigments concentration, gas exchange, and chlorophyll fluorescence of tomato plants under salt stress (0, 50, 100 and 150 mM) was studied in the greenhouse. Under salt stress, mycorrhizal tomato plants had higher dry weight of shoot and root, higher height, higher carotenoid an...
