Gaseous Sulfur Pollutants from Urban and Natural Sources

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...

Reducing Pollutants from Mobile Sources

Results of experimental investigations of using a coil-shaped injector for reducing NOx emissions from a diesel engine are presented. The study involved the effects of coil length and its mixing effectiveness and the development of the injector system for after treatment of diesel exhausts. Results indicate that the coil-shaped injector system with the ratios of length, pitch and wire diameter ...

ECC Sources of Gaseous Microemboli

___________ _ We have tried to locate sources of gaseous microemboli during the ECC using a newly developed ultrasonic detector. The detector was calibrated with filters of known pore size and the recorder setting was kept constant at all times. We studied, at the oxygenator, the effect of low and high fill volume, refilling with or without air into the cardiotomy line, mechanical disturbance, ...
