https://doi.org/10.1007/978-3-319-13773-5he ultimate control of pollution requires reliable analytical methods capable of accurately delineating the problem in all of its aspects. All too often “black boxes” are used to measure pollutants. The instruments used may provide valid information but more often than not they measure some general,

Fredda Blanchard-Fields,Christopher Hertzogreas in the United States (.), Problems which are associated with evaluating and quantifying the presence of odorants in the air comprise one of the most difficult of scientific pursuits, yet these problems must be solved if we are to attempt to bring about control of odorous emissions. It is essent

Ulrich Hecker,Stephan Dutke,Grzegorz Sedekh from a power plant and smoke particles from a home furnace have been analyzed. It is shown that the oxidation states of sulfur in compounds adsorbed on these solids can be determined. The use of photoelectron spectroscopy for studying the effects of combustion variables and downwind conditions on

Lecture Notes in Computer Science. Stress was placed on the development of reductive procedures wherein nitrate and/or nitrite could be determined by a slight modification in the basic procedure. Of the large group of reducing agents the hydrazine-cupric ion system was found to be especially attractive. Nitrite formed in the reacti

Lecture Notes in Computer Sciences. Quantitative extractions of polar organic molecules containing hydroxy1 groups from complex mixtures containing inorganic and organic components was found to be an extremely difficult problem that will necessitate many studies before the best solutions will be found. In this preliminary study it

Agile Parsing to Transform Web Applications methods used lack the desired precision and accuracy. Also, absence of specificity inherent in many techniques can lead to complications. Atomic absorption and flame emission are being evaluated for the determination of selected elements encountered in atmospheric particulate. As a laboratory contr

Aerometric Data: Needs and Networks,ose nature depends on the emission sources, meteorology, and topography of the affected area. It is a nationwide, as opposed to a national, problem, Furthermore, since control must ultimately be accomplished in the affected area, the Clean Air Act states that “the prevention and control of air pollu
