Lead (Pb) | Encyclopedia

Human exposure to lead can occur in a variety of ways, all of which involve exposure to potentially toxic elements as environmental pollutants. Lead enters the body via ingestion and inhalation from sources such as soil, food, lead dust and lead in products of everyday use and in the workplace. The aim of this review is to describe the toxic effects of lead on the human body from conception to

Active Packaging Appliions for Food - Yildirim - 2018 - …

A novel iron‐based OS using iron nanoparticles, blended with activated carbon, sodium chloride, and calcium chloride, was produced and evaluated by Mu and others (). Nanosized iron‐based OS (110 nm average particle size) exhibited a higher oxygen‐scavenging rate (estimated 13.5 mL/d) compared to the OS‐containing microscale pure iron powder (about 20 μm; estimated 1.8 mL/d).

Radiation: The Good, The Bad, and Its Place in Our …

Radium is an alkaline earth metal, just like calcium. Because elements in the same column undergo similar reactivity, the radium in the paint was shuttled to Mollie’s bones as if it were calcium. There, the radium decayed and emitted alpha particles directly to her bones and internal organs.

Minerals | Free Full-Text | Cleaner Extraction of Lead from …

A novel and cleaner process for lead and silver recycling from multiple lead-containing wastes, e.g., lead ash, lead sludge, lead slag, and ferric sludge, by reductive sulfur-fixing smelting was proposed. In this process, coke and iron-containing wastes were employed as reductive agent and sulfur-fixing agent, respectively. A Na2CO3-Na2SO4 mixture was added as flux. The feasibility of this

Effects of Pyrolysis Conditions and Feedstocks on the …

Pyrolysis conditions in charcoal production affect yields, properties, and further use of charcoal. Reactivity is a critical property when using charcoal as an alternative to fossil coal and coke, as fuel or reductant, in different industrial processes. This work aimed to obtain a holistic understanding of the effects of pyrolysis conditions on the reactivity of charcoal. Notably, this study

Copper - Wikipedia

Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals).This led to very early human use in several regions, from c. 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, c. 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposefully alloyed with another

High-Temperature Wetting and the Work of Adhesion in …

This article reviews data on wetting and the work of adhesion in metal/oxide systems at high temperatures in terms of proposed mutual adsorption models. Favorable adsorption energies can induce changes, especially near the high- and low-(O) limits of the coexistence range that often mimic bulk oxidation or reduction reactions. However, in some systems, an intermediate range of (O) exists

The presence of heme pigments and trace amounts of metallic ions makes the fish, especially dark flesh fatty fish, prone to lipid oxidation. Released hemin from Hb has the ability to stimulate lipid oxidation (Tappel 1955 ) as it alyzes the breakdown of preformed lipid hydroperoxides, thereby initiating the production of alkoxyl radicals.
