were 0.007–5.2 (ng/g), as shown in Table 2. As can be seen, the
LODs and LOQs allowed the determination of both minor and trace
elements at the required levels.
Precision is described as the degree of variability given by the
expression of results, not taking into account the influence of the
sample (sample variability). Chudzinska and Baralkiewicz (2011),
evaluated precision by using relative standard deviation of 10 repeated
determinations of one sample. Following this method, the
percent coefficient of variation (CV%) obtained are shown in Table
2. The values obtained were in the range of 0.99–5.38%. Only
Cu and Li were having CV% values of 5.38 and 5.31, respectively
