Abstract

Textile dyeing effluents were considered as the major cause of aquatic pollution in India. Many studies on textile dyeing effluents (TDE) have proved that they inflict serious damage to aquatic ecosystems. Mingling of TDE to any water body poses a great threat to aquatic life which needs to be explored. In the present investigation the effluents samples from 6 different textile industries (ST1, ST2, ST3, ST4, ST5 and ST6) of Pallipalayam area of Namakkal district were analyzed and impact on the activity of acetylcholine esterase were estimated in the larvae of B. geminata. It was interpreted from the results that TDE contain a lot of organic and inorganic pollutants comprising metals and chemicals. When the larvae of B. geminata exposed to these pollution loads, the homeostasis was seriously affected in terms of enzymes. It implies that TDE were not properly treated up to the world’s standard norms and proved detrimental to aquatic biota.
