Histochemical changes in the liver of freshwater fish, Rasbora daniconius, exposed to paper mill effluent

Abstract

This investigation deals with the effect of paper mill effluent, on the histochemical components of the liver of Rasbora daniconius. The Paper mill effluent was collected directly from the 45 Km away from Aurangabad (MS) India. Histochemical studies on protein, lipid and glycogen contents of liver Rasbora daniconius showed a progressive decrease in staining intensity to Mercury bromophenol blue (Hg-BPB), Sudan black B and Bets's Carmine at 30 days exposure when treated at sublethal concentrations (1.9% and 0.95%) of paper mill effluent. The magnitudes of these changes were dose dependent. This study, therefore, concludes that paper mill effluent creates metabolic crisis and impairment in fish liver. The depletion in level of protein, lipid and glycogen points towards exhaustion of cell-energy to meet high demand of fish in stressful condition.

96 h LC50, behavioural alterations and histopathological effects due to wastewater toxicity in a freshwater fish Channa punctatus

“…The loss of equilibrium might be due to the inactivation of central nervous system and failure of latero-acoustic system due to the inactivation of acetylcholine esterase activity, as suggested in earlier studies (Verma et al 1978;Pathan et al 2009;Bhat et al 2012). Decreased opercular movement possibly helps in reducing absorption of toxicants through gills as reported by Bhat et al (2012) in Labeo rohita when exposed to NEEM-ON biopesticide.…”

Histopathological Alterations in Common Carp (Cyprinus carpio L.) Gills Caused by Thiamethoxam

“…Pesticides are the class of compounds that despite of their benefits may produce a range of toxic effects that pose potential hazards to the environment. It is well known that their application could present a contaminant source for the aquatic environment (Kolpin et al 1998;Pathan et al 2010). Thiamethoxam is one of the neonicotinoids, which is used for controlling insect pests from paddy and cotton fields.…”

Effect of Crude Oil Water Soluble Fraction Toxicity on Tilapia Guineensis Fingerlings Using Histology of the Kidney as a Bioassay Indicator

“…They can cause loss of equilibrium, increased biological activities and irregular movement and eventually death in fish. These crude oil toxicants find their way into the body system of aquatic animals (Fishes) during oil spill or leakages through the gills, digestive tract and general body surface causing significant damage to the internal organs and tissues [2]. Histological studies have been used to establish fundamental relationships between contaminants exposure, various biological responses and changes to target fish organs in the laboratory [3].…”
