Table 1.

Results of mercury determination for a cod sample analysis by the proposed method and CVAAS.

Sample amount (g)	Proposed method(μg/g)^a	Recovery(%)^b	CVAAS(μg/g)^a	Recovery(%)^b
Cod (2.0083 g)	0.239±0.012	-	0.228±0.008	-
Cod (2.0076 g +0.6 μg Hg (standard solution))	0.524±0.021	95.3	0.520±0.008	97.6

^a)

All values represent a mean for four measurements ± k x standard deviation (where k=3).

^b)

Recovery. Mercury recovery was calculated by determining the mercury amount (μg/g) in a cod sample and in another one to which a known amount of mercury was added (μg/g). The difference between these two quantities represents the recovered mercury. Ratio between recovered mercury to the added one gives the recovery degree.
