Heavy Metal Residue (As, Cd, Hg, and Pb) in Hen Eggs after Applying Different Cooking Methods

Table 2

Comparing the of the heavy metals residues of raw and two methods (boiling and dry-frying) on hen eggs.

Heavy metals (μg.kg^-1)	Raw ()	Boiling		Dry-frying ()
		With shell ()	Without shell ()
As	^a†	^a	^b	^b
Hg
Cd	^a†	^a	^a	^b
Pb

Poached. †Significant differences between ^a and ^b in terms of As and Cd concentrations between boiling with shell, without shell, and dry-frying ().
