... Abstract abstractThe facile reaction of nitroso aromatics with glyoxylic acid to produce aromatic hydroxamic acids was further investigated in an attempt to determine the specificity of this reaction for glyoxylic acid. Neither pyruvic acid nor trifluoroacetaldehyde was found to react with C...

... Abstract The results of the detection of carcinogenic aromatic amines in about 300 ink samples are discussed. All analysed inks contained at least one or more azo compound pigments, and the presence of aromatic amines could only have originated from these compounds through a chemical process...

.... Therefore, these pigments often do not comply with the purity limits of the resolution; however, it is required that every distributed tattoo ink does not contain aromatic amines and not exceed the limits of heavy metals or polycyclic aromatic hydrocarbons. Current toxicity studies of pigments underline...

... and processed tobacco differ widely with the type of tobacco plant, and method of cultivation, harvesting and curing. Major toxic constituents of tobacco smoke are volatile organic chemicals, free radicals, nonvolatile polycyclic aromatic hydrocarbons, aromatic amines, heterocyclic amines and metals. N...

... with various exogenous factors. Usingadvanced and accurate exposure assessment tools, recent epidemiological data indicate thatoccupational exposure to chemicals, primarily to aromatic halogenated hydrocarbons, is amajor risk factor to develop MF in men (odds ratio 4.6), while exposure to pesticides...
