Answer to Question #156237 in General Chemistry for Namal

Question

How would we use atomic absorption spectroscopy to analyze heavy metal content in suspected water in tissue sample of liver which has gotten unknown heavy occupational exposure

Answer 1

Atomic absorption spectrometry is an analytical technique that measures the concentrations of elements qualitatively and quantitatively. ... Therefore, the determination of heavy metals (Mn, Pb, Cr and Cd) concentration is paramount important in this study.

This work focused on the determination of Mn, Pb, Cr and Cd concentrations in Kulufo River water, Arba Minch, Gamo Gofa. The concentrations of Mn, Pb, Cr and Cd were determined from the Kulufo River water by using FAAS technique. The results showed that the highest concentrations of Mn, Pb, Cr and Cd were found from the work areas.

In summary of the obtained results, it has emerged that the highest levels of the selected heavy metals in the work areas were detected 

in the River water samples collected from Kulufo. This is due to the highest traffic densities present near to the Arba Minch town. The total concentrations of heavy metals (Mn, Pb, Cr and Cd) in the Kulufo River water were above the critical maximum levels (the standard concentrations reported by WHO for drinking water) above which toxicity is possible. From this point view Kulufo River water was contaminated by these metals concentration. Therefore, treatment 

requires removing this contamination, because the transport flows and the factories are increasing day to day.
