摘要

A two-year study on the water quality and eco management of the Kondurupalem lagoon inlet located between 14*32' N latitude and 79*54' longitude on the east coast of India was conducted (2015 and 2016). The digital data image and spatial analysis weredone using Digital Imaging Software and the seasonal variations in select physico-chemical parameters were recorded employing standard methods to describe the general water quality condition of the inlet. Alkaline pH was recorded throughout the study atall stations and this trend could be attributed to the high salinity of water. The DO levels were high during the monsoon season with a mean value of 6.8 mg/L. Asignificantly low DO of 2.2 mg/L observed at the sampling station located at the sea mouth area appeared to be linked to movement and temperature of water and salinity. The average pre-monsoon salinities ranged from 37 to 42.5 per cent during both the years. During monsoon, the values dipped between 21.3 to 24 per cent in 2015 and 22.3 to 26.1percent in 2016, respectively. The turbidity during summer varied from 2.8 to 3.9 NTU and in pre-monsoon period from 2.4 to 3.1 NTU for 2015 and 2016, respectively. The turbidity during monsoon and post-monsoon varied from 4.1 to 8.2 NTU and 3.8 to 6.7 NTU, respectively for these years. The phosphates value during the pre-monsoon season were 208.53 and 288.66 ug/L for these years. This trend is an indication of excessive run-in of inorganic phosphates from fertilizers used in the nearby agricultural fields, into the lagoon. The mean nitrate concentrations during the monsoon and post-monsoon season were 52.60 and 39.52 ug/L in 2015 and 55.38 and 39.48 ug/L in 2016, respectively. However, there was a decrease in the mean value during the summer and pre-monsoon seasons. The high post-monsoon bicarbonate levels of 68 - 202 mg/L fell to 75-160 mg/L during monsoon and summer seasons. Monsoon precipitation, natural and human induced closing and/or opening of the inlet mouth and the consequential changes in the hydrodynamics and the anthropogenic inputs from the adjoining semi-urban habitation appear to influence water quality in this ecosystem.
