Preparation of 1-nitronaphthalene

In wood-tar-containing shampoos, benzo [a]pyrene was detected at concentrations in the low microgram per kilogram range, but 150 mg benzo [a]pyrene were found in one tar bath (State Chemical Analysis Institute, Freiburg, 1995).

Alizarin, like quinine and many potential novel dyes, was, from around 1850 considered to be related to coal tar compounds. Analysis indicated that the starting point for alizarin might be naphthalene. Indeed, once the aniline colors appeared, synthesis of alizarin from naphthalene was investigated in Germany, France and Britain. However, no useful products appeared. The breakthrough occurred in 1867 at the Gewerbe Institute, a trade college in Berlin. There since 1860, Adolf Baeyer had undertaken research into natural products, and had shown a keen interest in indigo and alizarin. His assistant Carl Graebe established that alizarin was probably a quinone, and went on, with Carl Liebermann to show that it was a derivative of anthracene, and not naphthalene. Alizarin was, as they demonstrated in 1868, a dihydroxyanthraquinone.[21] Synthesis was achieved by bromination of anthraquinone, followed by hydrolysis.

Benzo [a]pyrene was also detected at levels of 0.1-5.0 ng/litre in groundwater (Woidich et al., 1976).

Between the early and the mid-1970s, the total release of PAH (including nitrogen-containing analogues and quinone degradation products) into the atmosphere in the USA due to open burning was estimated to be about 4000 t/year (Agency for Toxic Substances and Disease Registry, 1990).

In measurements of the photodegradation of benz [a]anthracene and benzo [a]pyrene, addition of humic acids and purging of the solution with nitrogen reduced the reaction rates significantly (Mill et al., 1981).
