Studies on heavy metal contamination in Godavari river basin

Abstract: Surface water samples from Godavari river basin was analyzed quantitatively for the concentration of eight heavy metals such as arsenic, cadmium, chromium, copper, iron, lead, nickel and zinc using atomic absorption spectrophotometer. The analyzed data revealed that iron and zinc metals were found to be the most abundant metals in the river Godavari and its tributaries. Iron (Fe) recorded the highest, while cadmium (Cd) had the least concentration. Arsenic, cadmium, chromium, iron and zinc metals are within th… Show more

“…The presence of Cu in drinking water has been associated with non-Indian childhood cirrhosis, a form of early childhood liver cirrhosis [40]. The source of copper in the water can be agricultural activities and sewage sludge [41]. Use of copper and copper alloys in water pipes and plumbing fixtures increases the risk of copper levels in the water.…”

“…Nickel is an essential metal for living organisms and toxicity symptoms that can occur when the redundancy or deficiency of this element might happen. The quantity of nickel can vary; in earth's crust with around 1.2 mg/L, in soils 2.5 mg/L, in streams it is 1 μg/L and in groundwater it is <0.1 mg/L [12]. Nickel concentration increases also with anthropogenic activities; mining works, emission of smelters, burning of coal and oil, and sewage [13].…”

“…Iron is an essential element and the most abundant in the earth's crust, and it is present in the environment mainly as ions Fe 2+ or Fe 3+ . This heavy metal is generally present in surface waters as salts containing Fe(III) when the pH is above 7 [12]. Fig.…”
