A review on effect of sugar mill effluents on histopathology in freshwater fish
Authors

Abstract
Sugar mill
effluents, an important cause of industrial pollution, are a severe threat
to aquatic life, especially freshwater
fish. The effluents carry high amounts of
organic and inorganic pollutants, including heavy metals,
pesticides, and other toxic compounds, which can cause severe
histopathological changes in fish. High levels of contaminants are
found in water quality parameters, especially in chemical oxygen demand (COD)
and biological oxygen demand (BOD). This review focuses on changes in
vital organs such as gills, liver, kidney, Heart, stomach, intestine, and
Ovary. These studies indicate that continuous exposures lead to damage of
gill lamellae, degeneration of the liver, and renal impairment,
loss of striation in cardiac muscle, disintegration of the epithelial duct,
hydropic degeneration at the tips of the villi and thickening of ovarian wall,
after all affecting fish health, growth, and survival.
The extent of these effects changes depends on effluent
concentration, exposure time, and fish species. Such information on the
histopathological changes can serve as indicators of fish health, ecosystem
stability, and environmental disturbances.
