abstract
Amphibians decline rapidly in the areas where pollution is high. Contamination in water reservoirs affects amphibians very badly as their physical as well as physiological development depends on the quality of their aquatic ambient. Present study that concerns with analysis of water quality and seasonal changes was conducted to know the status of amphibian environment in District Hyderabad. This investigation was carried out during 2013 during which water samples were collected from permanent amphibian dwelling in agricultural ponds. Water samples were analyzed via ultraviolet-visible spectroscopy. The study revealed water quality polluted due to high values of Sulphate (443.7±133.2), Phosphate (432.6±123.8), Nitrite (4.6±1.7) and Nitrate (7.4±3.2) during entire study period. This analysis discovered that the amphibians are exposed to high contamination in District Hyderabad; hence concerned authorities must take quick efforts to save amphibian fauna from declination.
