Wastewater disposal from various sources are polluting the environment and disturbing our ecosystem at various levels. Industries are of special concerns due their effluent containing various contaminants which may have deleterious impact on environmental health. Concerning to current industrial pollution problem, the effect of industrial wastewater from Poolpur and Naini on different ecotoxicological parameters of selected fresh water fish Guppy spp Poecila reticulata was studied in laboratory conditions up to 96 hours. The increase space between gills and operculum, excessive excretion as well as increase surface activity were found in wastewater exposed fishes in comparison to control. The overall findings of the study indicates that industrial wastewaters are safe for crop irrigation but may have some negative impact on environment as on the basis of behavioural changes in effluent exposed fishes.

TREATED MUNICIPAL WASTEWATERS: EFFECTS OF ORGANIC FRACTIONS ON DEVELOPMENT AND GROWTH OF FISHES
Environmental Toxicology and Chemistry, 1992
Effluents from publicly owned treatment works (POTW) supply >98% of point-source pollutants and 13% of total freshwater input to the Hudson-Raritan estuary. We have studied the effects of chlorinated secondarily treated effluents on the sensitive early life stages of three species of fish common to this estuary. One source of effluents is a POTW that receives about half of its input from industrial sources. Previously, we demonstrated effects on development and growth of estuarine fishes of the effluent at 5 10% in seawater. This report presents similar studies using organic fractions of the effluent at concentrations equivalent to 10% in seawater in order to identify the most toxic class of compounds. We have found that the toxicity of batches of this effluent is quite variable in toxicity when tested with embryos of the winter flounder (Pseudopleuronectes arnericanus) or mummichog (Fundulus heteroclitus). In different batches of effluent, the organic base fraction or the organic acid fraction was primarily responsible for the toxicity.

We gratefully acknowledge the support of the participating water companies in this work and the members of the research teams at Exeter and Brunel for their help in sampling the fish. We recognize the (unpublished) work of A. Filby, who developed the basis for assessing the effects of endocrine-disrupting chemicals on kidney structure in fish. We acknowledge the contribution of E. Santos in establishment of the vitellogenin immunohistochemistry protocol.
