Assessment of the pollution status of the sediment and water of awash river during dry season in dendi district oromia ethiopiaDetermination Of Selected Heavy Metals And Physicochemical Parameters Of Fincha, Amarti And Nashe Lakes Water In Horo Guduru Wellega Zone, Oromia Regional State, Ethiopia

Abstract

Increased anthropogenic activities such as the discharge of industrial, agricultural and sewage waste effluents into the environment pose a potential threat to the fresh water ecosystem including lakes. Heavy metals and physicochemical parameters are amongst the most serious environmental pollutants to humans and aquatic fauna owing to their high toxicity, abundance and ease of accumulation. Fincha, Amarti and Nashe lakes are manmade lakes located at Horo Guduru Wolegga zone,Oromia Regional State in the western Ethiopia. In view of this, some physicochemical parameters (electrical conductivity (EC)and total dissolved solids (TDS), total hardness (TH), and Phosphate ion
