Quantitative Determination of Minerals and Toxic Elements Content in Tropical and Subtropical Fruits by Microwave-Assisted Digestion and ICP-OES.

In the presented study, 15 tropical and subtropical fruits were studied for their mineral composition ranging from trace to major elements by ICP-OES after microwave digestion. The moisture amounts were assigned to be between 21.90 (tamarind) and 95.

The Role of Edible Bulbous Layers on Macro, Micro, and Heavy Metal Contents of Leek (Allium porrum) Plant.

In this study, the degree of accumulation of biogenic element and heavy metal contents of different parts and edible layers of leeks cultivated in Konya in Turkey was revealed. The amounts of P and K of leek were determined from 154.69 (leaf top of leek) and 985.

The accumulation of element and heavy metal concentrations in different parts of some carrot and radish types.

Vegetables, which are an important part of human nutrition, are very rich in minerals necessary for human health, and heavy metals can be found in vegetables at high rates because they can be easily taken by plant roots and leaves. In this study, the macro, micro element and heavy metal element concentrations accumulated in different parts of some carrot and radish types were investigated. The element concentrations in the samples were analyzed by Inductively coupled plasma optical emission spectrometry (ICP-OES; Varian-Vista Model) equipment.

Macro-, micro-, and heavy metal element levels in different parts of celery (Apium graveolens L.) plant.

Potassium (K) was found in the highest amount in the macroelements of the celery plant, followed by P, Ca, Mg, and S in decreasing order. P and K amounts of celery plant parts were measured between 619.57 (leaf of celery) and 1244.

Determination of macro-, micro-element and heavy metal contents localized in different parts of three different colored onions.

The element found at the highest amount in onion samples was sulfur, and followed by K, Ca, P, Na, and Mg in decreasing order. While K contents of white onion parts are determined between 1406.31 (outer most edible) and 1758.
