Determination of Copper and Study Its Poisonous Effects in Drinking Water in Baghdad area

Abstract

Abstract:The objective of this study is to determine the concentration of copper(mg/L) indrinking water by using chromogenic agent from different area in Baghdad & with differentintervals , The results show that the concentration of copper ( mgL) in tap water whichremains motionless in plumbing system for following periods one hours, 3 hours, 6 hours, 12hours, 24 hours, 7 days and 14 days are 1, 2.2, 4, 5.3, 7.5, 10 and 16 mgL respectively.From these results it clear that a high levels of copper occur if corrosive water comesin contact with copper plumbing and copper-containing fixtures in the water distributionsystem. If corrosive water remains motionless in the plumbing system for some time.These amounts of copper are believed to have given rise to the symptoms of chemicalfood poisoning precipitated by the ingestion of alcohol on an empty stomach. Also childrenunder one year of age are more sensitive to copper than adults. Long-term exposure (morethan 14 days) to copper in drinking water which is much higher than 1,000 ug/I has beenfound to cause kidney and liver damage in infants.Keywords: Spectrophotometry; 1-(2-pyridylazo)-2-napthol; copper determina-tion.
