  • Acetylcholinesterase: a potential biochemical indicator for biomonitoring of Fertilizer Industry effluent toxicity in freshwater teleost, Channa striatus.
    Ecotoxicology, 2008
    Co-Authors: Archana Yadav, Anita Gopesh, Ravi S. Pandey, Devendra K. Rai, Bechan Sharma
    Abstract:

    Monitoring of acetylcholinesterase (EC: 3.1.1.7, AChE) activity has been widely used in aquatic and terrestrial systems as an indicator of pollutant exposure. The reports regarding impact of Fertilizer Industry effluent on the level of AChE activity are very scanty. In this paper, an attempt has been made to investigate the in vitro impact of Fertilizer Industry effluent upon the levels of AChE activity and protein content in different tissues of non-target aquatic fish, Channa striatus (Bloch). The fish when exposed to three sublethal concentrations (3.5, 4.7, and 7.0%; v/v) of Fertilizer Industry effluent for short (96 h) and long (15 days) durations registered sharp reduction in the levels of AChE activity (15–75%) and protein (10–71%) in different fish organs. The highest effluent concentration treatment for short or long duration, the fish brain and gills registered significant (P < 0.001) inhibition (64–75%) in the activity of AChE whereas other organs such as muscles, liver, and heart exhibited slightly lower inhibition (40–59%) in enzyme activity. However, kidney of C. striatus was the only organ where very less effect (14–18%) of the effluent was observed on the activity of AChE when the fish were exposed to all the three concentrations of the effluent for both treatment durations. This effluent also induced alterations in the level of protein in different fish organs; in kidney the effect was pronounced only at higher concentrations at both treatment durations. The most affected organs were muscle and gills where in 60–71% reduction in the protein content was recorded due to highest effluent concentration treatment at short or long durations. The results of present study indicated that the Fertilizer Industry effluents might significantly influence the neurotransmission system and protein turnover in the non-target organisms after exposure even at very low concentrations. Further, the data suggested that the fish AChE could be used as a potential biochemical marker for Fertilizer Industry effluent pollution in aquatic systems.

  • Fertilizer Industry Effluent Induced Biochemical Changes in Fresh water Teleost, Channa striatus (Bloch)
    Bulletin of Environmental Contamination and Toxicology, 2007
    Co-Authors: Archana Yadav, Anita Gopesh, Ravi S. Pandey, Bechan Sharma
    Abstract:

    The industrial activities pose threat to the life of aquatic organisms in many ways. This research communication presents an account of the impact of Fertilizer Industry effluent upon the levels of protein and the activity of lactate dehydrogenase (EC 1.1.1.28, LDH), a terminal key enzyme in glycolytic pathway, in different organs of a fresh water teleost fish, Channa striatus ( Bloch ) . The fish exposed to different sublethal concentrations of Fertilizer Industry effluent (3.5, 4.7 and 7.0% v/v) equivalent to 1/20th, 1/15th and 1/10th of LC_50 value (70% v/v) for varying treatment periods (96 h and 15 days) exhibited decrease in the level of protein (8–76%) in different organs of the effluent treated fish. At highest effluent concentration (7% v/v) treatment for short (96 h) or long (15 days) duration, the liver of the fish registered significant ( p

The fish exposed to different sublethal concentrations of Fertilizer Industry effluent (3.5, 4.7 and 7.0% v/v) equivalent to 1/20th, 1/15th and 1/10th of LC50 value (70% v/v) for varying treatment periods (96 h and 15 days) exhibited decrease in the level of protein (8–76%) in different organs of the effluent treated fish. At highest effluent concentration (7% v/v) treatment for short (96 h) or long (15 days) duration, the liver of the fish registered significant (p < 0.001) decrease (62–76%) in protein content as compared to control, whereas other organs of the fish showed only 38–52% decrease in the level of protein. The industrial effluent also caused marked reduction in the activity of LDH in different fish tissues when compared to the control. The treatment of fish with 7% effluent concentration for 96 h caused 78% decrease (p < 0.001) in the LDH activity in fish muscle whereas after 15 days the effect was maximum in fish brain as it exhibited 86% decrease (p < 0.001) in LDH activity as compared to control. The effect of effluent on the activity of LDH and protein content in different body tissues of the fish was dependent on concentration and duration of exposure. The significant reductions in the activity of LDH and level of protein in fish tissues due to treatment with the Fertilizer Industry effluent indicated the possibility of impairments in energy metabolism and protein turnover, respectively, in C. striatus.
