Toxicity of three textile dyes-Optilan yellow, Drimarene blue and Lanasyn brown, was evaluated in a green alga Chlorella vulgaris. The unialgal populations of the alga showed a concentration-dependent decrease in specific growth rate and pigments after exposure to graded concentrations of above dyes. The elemental profile (C, H, N, S) of the treated and untreated cells showed a change which was evident from a significant decrease in the quantity of elements after exposure to the dyes. The observations provide convincing evidence that the textile dyes inhibited the growth, pigment and elemental composition of the algal cells. The findings of the present investigation will contribute to gaining a better understanding of the impacts of textile dyes on ecologically important aquatic organisms.

A material used in the manufacture of azo dyes that is toxic to skin and carcinogenic in several species.
Highly toxic compound which can cause skin irritation and sensitization. It is used in manufacture of azo dyes.
Protein complexes that take part in the process of PHOTOSYNTHESIS. They are found in the THYLAKOID MEMBRANES of PLANTS and other photosynthetic organisms. There are two major complexes involved in the photosynthetic process called PHOTOSYSTEM I and PHOTOSYSTEM II.
Dyes used as cosmetics to change hair color either permanently or temporarily.
Green dyes containing ammonium and aryl sulfonate moieties that facilitate the visualization of tissues, if given intravenously. They have mostly been used in the study of kidney physiology.
