The contents (mg/100 g) of iron, zinc, and calcium in 55 samples of fresh fishery products including shrimp from Bangladesh ranged from 0.34 to 19, 0.6 to 4.7, and 8.6 to 1000, respectively. Shrimp had maximum copper and iodine contents of 1200 and 120 μg).
Boron is a metalloid that plays an important role in the functioning of cell merane, enzymatic reactions and the hormonal and mineral metabo-lism of animals. Boron is also thought to be an essential metalloid for animals. Boron compounds have a wide range
One possible explanation is that lead is deposited in the bones rather than soft tissue replacing calcium of bone tissue (Hoogesteijn et al. 2003). On the other hand, lead has a very short half-life in the blood, just a few days, and while in liver and kidney is from weeks to months, but on bone it remains for years, reflecting a lifelong exposure (Pain 1996).
Calcium is a chemical element with syol Ca and atomic nuer 20.Calcium is a soft gray alkaline earth metal, fifth-most-abundant element by mass in the Earth''s crust.The ion Ca 2+ is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and …

Few data exist about the effect of substrates’ elemental content on the respective concentrations in cultivated mushrooms, on the degradation of lignocellulosics or on production parameters. Sixteen elements (14 metals and 2 metalloids) were measured by inductively coupled plasma mass spectrometry (ICP-MS) in Pleurotus ostreatus and Cyclocybe cylindracea mushrooms, and in their seven

Field experiments were conducted on wheat to study the effects of foliar-applied iodine(I) alone, Zn (zinc) alone, and a micronutrient cocktail solution containing I, Zn, Se (selenium), and Fe (iron) on grain yield and grain concentrations of micronutrients. Plants were grown over 2 years in China, India, Mexico, Pakistan, South Africa, and Turkey. Grain-Zn was increased from 28.6 mg kg–1 to
Properties, occurrence, and uses Pure crystalline boron is a black, lustrous semiconductor; i.e., it conducts electricity like a metal at high temperatures and is almost an insulator at low temperatures. It is hard enough (9.3 on Mohs scale) to scratch some abrasives, such as carborundum, but too brittle for use in …
Characteristics A trivalent metalloid element, boron occurs abundantly in the ore borax. Boron is never found free in nature. Several allotropes of boron exist; amorphous boron is a brown powder, though crystalline boron is black, hard (9.3 on Mohs'' scale), and a weak conductor at room temperature.
