Assessment of trace elements in animal tissues from Turkey

Abstract

In this study, trace element contents of animal tissues were determined by atomic absorption spectrometry after microwave digestion method. The accuracy of the method was confirmed by analysis of standard reference material (NIST SRM 1577b Bovine Liver). Trace element contents in animal tissue samples were found in the range of 98.3-18.2 μg/g (Fe), 2.89-0.26 μg/g (Mn), 23.9-4.54 μg/g (Zn), 0.08-0.01 μg/g (Pb), 32.9-1.66 μg/g (Cu), and 0.32-0.01 μg/g (Cd). The results were compared with literature values. The results obtained for toxic and trace elements in analyzed animal tissue samples were acceptable to human consumption at nutritional and toxic levels.

Trace Element Content of Monovarietal and Commercial Portuguese Olive Oils

“…However, in excessive concentrations it could be toxic for all forms of life 26 , a difference that, as aforementioned, might be related to the fertilizers used for increasing the olive production. The recommended daily intakes of zinc are 15.0 mg Zn for adult males and 12.0 mg Zn for adult females 27 , meaning that all the results obtained are safely under the limit, respecting a normal daily olive oil intake, and accounting with the contribution from a diversity of sources for the total Zn intake. …”

Some Heavy Metal Contents of Various Slaughtered Cattle Tissues in Sivas-Turkey

“…In fact, the heavy metal term is used as a physical property of the metals whose density is greater than 5 g/cm 3 . Heavy metals are classified as vital and non-vital metals according to their degree of participating to biological activities (1).Those that are defined as essential should be present in the organism at certain concentrations.…”

“…On the other hand, non-essential heavy metals (Pb, Cd, Hg, etc.) may cause health problems by damaging biologic structure even at the lowest concentrations (3)(4). Heavy metals have a risk potential for ecologic system and human health because, unlike organic polluter, they are not degraded, and they are accumulated in the food chain.…”

Determination and mapping of cadmium accumulation in plant leaves on the highway roadside, Turkey

“…It is known that these trace elements have the potential to accumulate in plants, animals, other living organisms and soil. Even a minimal concentration of some trace element ions like cadmium (Cd), lead (Pb) and arsenic (As) is toxic to living organisms (Mendil and Tuzen 2011).…”
