“…Small quantities of Cd cause adverse changes in the arteries of human kidney. It replaces Zn biochemically and causes high blood pressures, kidney damage, and so forth [32][33][34] . Because of their high toxicity, As, Pb, and Cd need to be quantified in food and beverages 35 .…”

There has been an increasing trend in the production and consumption of local and imported fruit juices in Iran. The presence of impurities and foreign matter in finished products for human consumption is of great concern because they present health hazards when they exceed beneficial limits. The manufacture of juices requires special attention in terms of purity and the sources of water and its purification are crucial for maintaining quality and safety. Biosorption can be deûned as the removal of metal or metalloid species, compounds and particulates from solution by biological material. citric acid content of beverages may be useful in nutrition therapy for calcium urolithiasis, achieving therapeutic urinary citrate concentration is one clinical target in the medical management of calcium urolithiasis. Information on the citric acid content of fruit juices and commercially-available formulations is not widely known. Levels of heavy metals: Lead, Cadmium and Nickel in 180 selected fruit juice commercially available packaged samples (Pineapple, Orange, Mango, Tropical, Cherry& Grape) purchased from Tehran local Market in 2014. Heavy metals were determined using atomic absorption spectrophotometer (AAS) by wet digestion method in Pharmaceutical Sciences Branch, Islamic Azad University Tehran-Iran. From the obtained result Ni, Cd and Pb were detectable in 85% of samples especially in Mango and Tropical juices. The efficiency removal of Nickel, lead and Cadmium and neutralization of calculus contain of juice by Citric acid as a chelating were carried out by using of Atomic Absorption Spectrophotometry technique. The result demonstrated the complexation formulating between the citric acid and heavy metals. The high efficiency of Citric acid played an important role in removal of lead and cadmium in addition to this removal were increased by increasing the citric acid. The enhancing of citric acid in removal of lead and cadmium caused to create a slightly tart, refreshing flavor and balance sweetness.

“…For the quality control of the analysis, three working standards were analyzed at the beginning and end of the sequence. The analytical procedure was adapted from the work of Magdas et al . with the isotope ratio values calculated against international reference materials: L‐glutamic acid USGS 41 (δ 13 C = +37.63‰, δ 15 N = 47.57‰) and ammonium sulfate IAEA‐N‐2 δ 15 N = 20.3‰ (IAEA – International Atomic Energy Agency, Vienna, Austria) and urea (δ 13 C = –26.39‰, δ 15 N = –4.52‰, IVA Analysentechnik, Messbach, Germany).…”

“…Co presence in soils is highly influenced by the formation of manganese oxides, which have a high absorption capacity. Within the upper soil horizon, there are notable correlations of Co with other trace elements [45]. The main Co source is geogene, but high contents were reported near motorways and roads.…”

The levels and distribution of 9 trace elements in apples from two orchards in north-east (NE) Romania were measured by means of Atomic Absorption Spectroscopy (AAS) on 42 samples of 9 different apple varieties, with average content ranges of 0.909–4.458 mg·kg−1 Zn, 0.055–0.409 mg·kg−1 Cu, 0.700–2.476 mg·kg−1 Fe, 0.328–0.695 mg·kg−1 Mn, 0.054–0.257 mg·kg−1 Ni, 0.005–0.101 mg·kg−1 Cr, 0.027–0.420 mg·kg−1 Co, 0.413–1.149 mg·kg−1 Pb, and 0.025–0.127 mg·kg−1 Cd. For some apple varieties, Pb contents are 2 times higher than the maximum contents allowed according to national standards, Cd contents are 6 times higher, and in some cases Zn contents also exceed the national threshold, showing preferential accumulation on specific apple varieties. Whilst some research has been carried out on trace element distribution in apples, this study assessed the areal distribution of toxic trace elements in connection to the adjacent roads. The first apple orchard is located near a county road, with reduced car traffic, while the second orchard shares its southern limit with a high-volume traffic road (E583). The results point towards a proportional increase of Pb and, to some extent, of Cd in the samples close to the E583 road in contrast with the other orchard, where no such observation derived. Along the areal distribution of the selected elements, the preferential accumulation of dietary recommended trace elements in different apple varieties was assessed. In matters of daily nutrients content in trace elements, the best sources of Fe, Cu, and Zn in terms of apple varieties are Golden Delicious, Jonathan, and Kaltherer Böhmer.
