تلوث مياه برادات الشرب محلية الصنع بأنابيب التبريد النحاسية

Abstract EN

The present research work studies the concentration of copper ions in cold drinking water because of the use of copper pipes in locally made water-coolers.

The concentrations of copper in the cold water were measured, using technique of Flame Atomic Absorption Spectrophotometery (FAAS).The results of the analysis indicate that cold water of the first group of water-coolers, after being used for less than one year, had copper concentration of (0.06mg/L) compared with (0.025mg/L) of the source water, with an increase of (2.4) times.

In the cold water of the second group of water-coolers, after one and half year, the concentration of copper reached (0.20mg/L) compared with (0.025mg/L) of the source water, with an increase of (8) times.

In the third group of water-coolers, after three years, the concentration of copper reached (0.60mg/L) compared with (0.025mg/L) of the source water, with an increase of (24) times.

In the third group, copper concentration reached the high boundaries allowed internationally and locally, hence drinking of this cooled water is unsafe for human.

The continuation of drinking this type of water, even in small doses for a long period, might lead to severe health problems, especially in young ones.
