“…The capability of the method as a routine analysis method was estimated through the determination of the detection limits of each element studied. The limits of detection (LOD) and limits of quantifi cation (LOQ), were calculated with three and ten timed the standard deviation of the blank divided by the slope of the analytical curve, respectively [Thompson et al, 2002;Khan et al, 2014]. The values of LOD were in the range of 0.251-18.321 μg/kg as it is presented in Table 1.…”

“…Although milk is a complex matrix composed of proteins, carbohydrates and lipids accuracy indicated good recovery from two different microelement spiked concentrations (10 and 50 μg L -1 ) in human milk pools (Table 4). 28 Specifically, average recovery ranged from 90% to 94% for Zn, 90% to 102% for Cu by ICP-OES and 97% to 103% for Fe by FAAS (Table 4). Blank samples and the 0.25 mg L -1 control standard were evaluated together with samples in each batch (Table 5).…”

“…25 Despite the fact that ICP-MS is highly sensitive, accurate and precise, it is the least used technique in clinical laboratories due to high instrument cost and demanding protocols. [26][27][28] Neutron activation analysis (NAA) is one of the most sensitive techniques for applications in clinical biology. However, analyses are time consuming and therefore largely inappropriate.…”

The concentrations of zinc (Zn), iron (Fe) and copper (Cu) in both human milk and infant formula were determined using a new sample preparation method, by inductively coupled plasma -optical emission spectometry (ICP-OES) and flame atomic absorption spectrometry (FAAS). Human milk samples were diluted in ultrapure water. The infant formula of powder samples (suitable for an infant 1-6 months of age) and standard reference material (SRM-1849) were analyzed in parallel. The results have shown that FAAS method was more sensitive for Fe determination in human milk while ICP-OES was more sensitive for both Zn and Cu detection. The limit of quantification for both Zn and Cu was 5 μg L -1 and 10 μg L -1for Fe and the recovery for Zn, Fe and Cu was ranged from 90% to 94%, 97% to 103% and 90% to 102%, respectively. Mean concentrations of Zn, Fe, and Cu in human milk samples were 5.35, 0.47 and 0.83 mg L -1, respectively while these values in infant formula were ranged from 3.52-4.75 mg L -1 , 3.37-4.56 mg L -1 and 0.28-0.41 mg L -1 , respectively. Despite the sample complexity, the proposed method using dilution of milk samples with water was simple, rapid, effective and accurate. ICP-OES was a better method for Zn determination while FAAS was a better method for Fe determination. In the case of Cu both methods were comparable.

“…Microelement content in milk and dairy products is normally very small. The highest levels measured were Zn, Cu, Mg and Cr, which are essential elements and very important for normal metabolism, growth and development (Khan et al, 2014). However, through manufacturing and packaging processes, their contents may be significantly increased.…”

“…Elevated concentrations may cause serious health problems. The extent of toxicity is related to factors such as the route of exposure, level of intake, solubility, metal oxidation state, retention percentage, duration of exposure, age, sex, frequency of intake, absorption rate and efficiency of excretion mechanisms (Khan et al, 2014).…”

Trace elements content in cheese, cream and butter

et al. 2014

Trace elements were determined in five types of cheese, cream and butter using inductively coupled plasma-optical emission spectrometry. In cheese samples trace elements were measured as follows (mg/kg): Al 0.01-3.93, Co<0.005, Cr 0.005-1.66, Li 0.008-0.056, Mn 0.068-5.37, Mo 0.003-0.225, Ni 0.01-0.163 and Sr 0.085-3.49. There were significant differences considering the concentrations of Mn, Cr and Al (p<0.01, all) among the analysed dairy products. There were no significant differences in Sr, Mo, Ni and Li levels among products. The highest levels were found in following products (mg/kg): 4.23 Mn in semi-hard fat cheese, 2.43 Sr in cream cheese, 0.18 Mo in cream, 0.14 Ni and 0.028 Li in melted cheese, 1.13 Cr and 3.87 Al in butter. The trace element concentrations measured in cheeses and butter varied compared to the literature data. Concentrations of Al, Cr, Mn and Mo found in cheeses and Mn and Ni in butter were in line with contents reported in other countries. These results may demonstrate differences in production processes between countries. The estimated daily intakes (EDIs) calculated for Cr, Mn, Mo and Ni in cheeses showed a low contribution (0.59-3.38 %) to the reference values for the permitted daily exposure (PDE) for these elements. However, the high contribution of Al concentrations (56 and 124 %) to PTWI (provisional maximum tolerable daily intake) calculated in fresh and melted cheese may pose a health risk to consumers.
