Abstract:
The study was conducted to determine the concentration of heavy metals lead and cadmium on Mallard duck eggs from Kapatagan, Lanao del Norte Philippines. Following the Complete Randomized Design (CRD) a total of 90 fresh mallard duck eggs were randomly collected from 3 duck farms of Kapatagan, Lanao del Norte. Fresh duck eggs were cleaned and cracked carefully to completely separate the egg yolk and egg white, placed in a separate plastic containers, labeled and transported directly to FAST laboratory for analysis. The analysis of heavy metals lead and cadmium were performed using Atomic Absorption Spectrophotometer (AAS). Results revelaed that fresh mallard duck egg yolks have significanty higher concentration of lead, higher than the recommended level of 0.43 mg/kg. The egg white samples from farm 2 have higher lead concentration than the samples collected from farm 1 and farm 3. Cadmium concentration in all egg yolk and egg white samples were at ?0.02 mg/kg. Based on the presented results it is thereby concluded that fresh mallard duck eggs from Kapatagan, Lanao del Norte is not already safe for human consumption.
