As shown in Figure 1, azo dyes such as methyl orange contain aromatic and -N=N- groups in their molecules, which are highly toxic, carcinogenic and teratogenic.
As shown in Figure 1, the molecules of azo dyes such as methyl oranges contain aromatic families and -N-N-groups, which are highly toxic, carcinogenic and teratogenic.
