Present Status of Coal Tar Industry in Europe

Coal tars and coal tar pitches.

Numerous studies, mostly case reports, have found that occupational exposure to coal tars or coal-tar pitches (coal-tar distillates) is associated with skin cancer, including scrotal cancer; workers in these studies have included patent-fuel (coal-briquette) workers, pitch loaders, workers in electrical trades, and optical-lens polishers (IARC 1985, 1987). A 1946 study in the United Kingdom fou...

Coal Tar Analysis by Lc/ms

The production of liquids from coal gives rise to complex intermediates which require detailed analysis to understand the processes occurring and to make effective use of the products. Analysis has hitherto been based on structural parameters from NMR methods (1) to give the average characteristics of the sample, supplemented by molecular information from GC and GC/MS. The gas chromatographic a...
