“…No information is available about the direct or the potential toxicity of this species, since a further degradation step can not be excluded leading to the possible formation of aromatic amines, as suggested by many degradation studies of different dyes reported in literature [18][19][20][21][22][23][24][25].…”

“…By HPLC-MS and GC-MS the main degradation products identified in the faded dye were the Michler's ketone, formed in the hydrolysis reaction of C NH 2 + group to C O and demethylation products [17]. Some authors report the formation of aromatic amines by exposure to natural light of some dyes [18][19][20][21][22][23][24][25], but this hypothesis must be discussed because aromatic amines are reported to be already present as impurities in many dye standards [18], as for example naphthylamine in amaranth [21] and p-cresidine and aniline in FD&C Red n. 40 [22].…”

“…No data are available about a direct toxicity for human health and environment coming from aromatic sulfonates. The threat to the environment is due to possible degradation processes of these chemicals, processes that can naturally occur after their disposal in the environment and that can lead, as reported by many authors, to the formation of toxic aromatic amines (Fogg and Summan, 1983; Garrigos et al, 2002; Lancaster and Lawrence, 1982, 1983; Lawrence et al, 1981; Richfield‐Fratz and Bailey, 1987; Stavric et al, 1979). Sulfonate wastes often are effluents of dye industries and are intensily colored.…”
