"Lovrin”). Net assimilation rate was only inhibited by the highest concentration of Nylosan Red, while stomatal conductance to water vapor was strongly influenced by all azo dyes. Concentrations of photosynthetic pigments, chlorophylls and carotenoids, were most strongly reduced in treatments with azo dyes especially with those which contained chromium in their molecular structure. These data collectively indicate important reduction of foliage physiological activity by textile dyes and indicate that emissions of leaf volatiles can provide a promising tool to assess the toxicity of different dyes.
