| description | Water is essential in sustaining life in all living organisms. Therefore, clean and safe
drinking water is essential for healthy living. As many parts of the world becoming
industrialized and urbanized, problems of water pollution are becoming more intensified
with many areas of surface water and ground water are being contaminated with heavy
metals. Due to that, the usage of vending machines are the alternative source of cleaner
and safer drinking water for the household consumer nowadays. However, the safety
and health aspect for these water vending machine with the respect to heavy metals
contamination in particular is not known. It is the aim of this study to determine as well
as to measure the presence and quantification of heavy metals in water sampled from
selected vending machine in Kubang Kerian, Kelantan. The concentration levels of
several selected heavy metals were tested using Flame Atomic Absorption Spectrometry
(FAAS). The heavy metals elements tested were Zinc (Zn), Copper (Cu), Iron (Fe),
Manganese (Mn), Lead (Pb) and Cadmium (Cd). It was found that 100.00% of the
samples contained Mn. However, it was also found that only six samples which present
20 .00% that have the concentration level of Mn that is under the maximum acceptable
value which set by the National Standard for Drinking Water Quality. The rest of the
samples (80.00%) have the concentration exceed the limit which is 0.05 mg/L. Eighteen
samples were found to have the concentration level for Cd that are non-compliance to
the National Standard for Drinking Water where as there are five samples are comply
with standard which is 0.005 mg/L. The excessive concentration of Pb in the water
vending machine found that 50.00% of the samples did not comply with National
Standard Drinking Water. The rest of the element which are Cu, Fe and Zn shown the
concentration were under the standard and there were also found that 14 samples from
Cu element, nine and six samples from Fe and Zn element respectively cannot be
detected by FAAS respectively due to too low concentration of these elements. Water
from water vending machines is unsafe for consumption due to the presence of heavy
metals exceeding the minimum safety limit. |
