Uptake and fate of gaseous pollutants in leaves

Adsorption of Gaseous Pollutants

Transport and fate of gaseous pollutants associated with the National Energy Program.

The experimental evidence related to the long-range transport and transformations of sulfates has been critically reviewed. It has been concluded that sulfate emissions from various sources can be superimposed on each other during long-range transport to create episodes far from the contributing sources. Sulfates are important contributors to degrading visibility through the United States inclu...

Gaseous pollutants in Beijing: variability, sources, and impacts

Atmospheric Chemistry and Physics Discussions This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Gaseous pollutants, NO y /NO x , SO 2 , CO, and O 3 , were measured at an urban site The concentrations of the pollutants show " saw-toothed " patterns, which are attribut...

Epidermal cell fate and patterning in leaves.

Cell differentiation requires that undifferentiated cells first be selected before becoming committed to a specific fate. The selection of precursor cells often is coordinated so that mature differentiated cells are distributed in a characteristic pattern. One of the simplest possible patterns in tissues is that in which a minimum distance is maintained between differentiated cells in a two-dim...
