[On the presence of 20-methylcholanthrene in the atmospheric air (author's transl)]
Abstract:
The strongly carcinogenic polycyclic aromatic hydrocarbon 20-Methylcholanthrene was detected in the urban atmospheric air in Budapest (the capital of Hungary). The main source of this pollution seems to be the motor vehicle traffic, since samples from a heavy traffic junction contained up to six times higher 20-Methylcholanthrene concentrations than samples from a low traffic area. Ultraviolet absorption spectrophotometry yielded similar results. The presence of 20-Methylcholanthrene is apparently connected with the presence of 3,4-Benzpyrene and 1,2-Benzpyrene, respectively.

The internal reference compound generally used in NMR spectroscopy is tetramethylsilane (TMS). TMS is preferred because it is chemically inert, soluble in NMR solvents, and easily removable. Also, the highly shielded methyl protons in TMS yield an intense...
