Assessment of Phenolic Compounds in the Surface Waters of Godavari Canal, Andhra Pradesh, India
نویسنده
چکیده
The present study was intended to determine the concentrations of phenolic compounds in surface waters of Godavari canal by molecular spectrophotometry. Samples were collected from fifteen sampling stations using grab sampling method for a period of four months (from November to February) at 10 day intervals. Total phenols in water samples were determined using molecular spectrophotometry after distillation, complexation with 4-aminoantipyrine and extraction into chloroform. The concentration of phenolic compounds was reported in the range of 80-179 mg/lit, well within the limits considering the earlier reports in the literature and the standards prescribed by Central Pollution Control Board (CPCB) of India. Relatively higher levels of phenolic compounds (100-179 mg/lit) were reported in nine out of fifteen sampling locations. Statistical analysis showed that there is a significant difference in the concentrations of phenolic compounds in the month of November with respect to January (at p = 0.05) and November with respect to February (at p < 0.05).

The Kolleru Lake is a famous Ramsar wetland of international significance. In this study heavy metal contents in water and sediment samples are reported. It is found that certain potentially toxic metal ions like chromium (4.5-80 µg/L), copper (1-20 µg/L), manganese (1-313 µg/L) and zinc (1.2-57 µg/L) are present in variable quantities in the lake water. When normalized with respect to concentr...
