Study on environmental impact of chemical pollutants & interpretation of characteristics using statistical technique in water quality of Keenjhar lake located in Sindh Pakistan

Concerns about the water quality in keenjhar lake,a fresh water lake,located in province of sindh,pakistan have been expressed recently due to the natural and anthropogenic pollution. in order to understand the underlying physical and chemical processes in keenjhar lake,the present paper determines quality indicators for periodical monitoring of the lake water quality factors identified by using principal components analysis on 17 physico-chemical parameters including five heavy metal ions representing eight different locations in the year 2013 in and around the lake. metals,in general,showed a moderate to high degree of correlation among them. principal component analysis and factor analysis have been applied to explore the source of the water quality parameters as the result of various anthropogenic activities.
