| description | Atomic Absorption Spectroscopy (AAS) technique was applied to determine and
analyse the concentration of heavy metal such as Zn, Pb and Ni in three different
skin whitening creams and one herbal cream that available from retail shop in
Jengka, Pahang. The samples were digested using acid and then analyzed using
AAS. All metals were detected in all samples but with different concentrations.
Zinc was range between 6.4 mg/kg and 17.7 mg/kg. Nickel and lead concentration
range were lower compared to Zn which were 3.1 mg/kg to 4.2 mg/kg and 6.2
mg/kg to 13.0 mg/kg respectively. The detection of Zn in the whitening creams is
under permissible limit as set by FAO I WHO and Health Canada 2007 standard
which is 50 mg/kg. Hazard index (HI) values for HI, WI, W2 and W3 were 2.13
x 10-6,4.39 x 10-6 ,3.33 X 10-6 and 3.65 x 10-6 respectively. All values of HI were
less than 1 and it is believed that there was no significant risk of non-carcinogenic
effects. However, some of the samples contained lead exceeds the permissible
limit set by FAO/WHO and Health Canada which is 10 mg/kg. Overall analysis
proved that the concentration of heavy metals in herbal cream, HI was lower
compared to other whitening creams, WI, W2 and W3. Since the HI values were
lower than 1, all products were safe to use. But, it is better to take precaution in
using whitening creams since the presence of excess heavy metals may lead to
accumulative toxicity in the body beyond the acceptable limit. |
