6. Water
Applications of AAS
• Detection of toxic heavy metal in water
(Drinking water – irradiation water - ground
water)
• The heavy metals have a great effect on the
human health as it may cause damage for vital
organs in the body.
• The most common toxic metals in water are:
Pb – Cd – Cu – As – Hg

8. Applications of AAS
• Detection of heavy metals in
mining locations is essential for
evaluation of the mining process.
• For example gold, zinc or silver
mines

10. Applications of AAS
• Detection of heavy metals in soil
is very important because :
 It may release inside the crops
and contaminate it.
 It could also migrate to the
drinking water.

12. Applications of AAS
• Detection of heavy metals in cement is very important
because: presence of some metals such as lead could
cause cracking for the concrete.
• Also the soil of the building site must analyzed to
confirm absence of any metals which may cause failure
for the process

14. Applications of AAS
Clinical analysis : Analyzing metals in
biological fluids such as blood and urine.
Medical

15. Applications of AAS
Pharmaceuticals :
• Confirm the presence of heavy metal if it
was the active ingredient such as :
 Fe in antianemic medicines
 Zn for skin infections drugs
 Cr for diabetics patients
Medical

16. Applications of AAS
Pharmaceuticals :
• Also in some pharmaceutical manufacturing
processes, minute quantities of a catalyst used in the
process (usually a metal) are sometimes present in the
final product.

18. Applications of AAS
• In the oil industry the detection of heavy metals is essential in
many stages:
 The formation water which is water from joints and pores in the
Marcellus Shale itself.
 Common heavy metals found in formation water include :
Fe, Cu, Pb, Ba, As, Cr, Mn, and Zn.
Crude Oil

19. Applications of AAS
In the crud oil production the heavy metals
must be evaluated because:
 some heavy metals may cause deficiency
in the final petroleum products
Crude Oil

20. Applications of AAS
 Also in case of oil spill it decrease
the biodegradation of the oil in
water.
Crude Oil

21. Applications of AAS
 Elements like Ni & V in oil may
determine the location of the well, Also
the V cause undesired side effects in the
refining process, and corrosion in oil-
fired power plants
Crude Oil

22. Applications of AAS
 Presence of metals such as Fe, Ca
and Mg may cause scale problem in
the pipe-line which may lead to
fatal loses.
Crude Oil

23. Applications of AAS
 One of the most toxic metals is Hg which
must be evaluated and managed to
reduce its effects on the production and
environment.
