Assessing the prevalence and severity of zinc deficiency in populations is critical to determine the need for and appropriate targeting of zinc intervention programs and to assess their effectiveness for improving the health and well-being of high-risk populations. However, there is very little information on the zinc status of populations worldwide due to the lack of consensus on appropriate biochemical indicators of zinc status. The objective of this review was to evaluate the use of serum zinc concentration as an indicator of population zinc status. We have reviewed the response of serum zi

Zinc is an essential trace element, making it crucial to have a reliable biomarker for evaluating an individual’s zinc status. The total serum zinc concentration, which is presently the most commonly used biomarker, is not ideal for this purpose, but a superior alternative is still missing. The free zinc concentration, which describes the fraction of zinc that is only loosely bound and easily exchangeable, has been proposed for this purpose, as it reflects the highly bioavailable part of serum zinc.

Zinc is a nutrient that affects cell growth, helps the body's metabolism, activates T cells (T lymphocytes), cell regeneration, and repairs body tissues.

Zinc adsorption in sixteen surface soil samples of Vertisol and Inceptisol was studied over a wide range of zinc solution concentrations (2.5 to 200 ppm). The zinc adsorption data conformed to Freundlich equation for the entire range of concentration tested. The Freundlich constants 'k' and 'n' were derived for zinc in these soils. The 'k' values ranged from 0.28 to 1.78 mg Zn/g with a mean value of 0.83 mg Zn/g soil. The 'k' values were significantly related to clay, CEC, silt, ex. calcium and free CaCO3.

The aim of this study,1 was to evaluate the impact of different zinc-containing topcoats on hydrogen re-embrittlement. In order to cause hydrogen induced cracking, hydrogen does not only need to be formed, but also needs to penetrate and migrate into the material. The hydrogen entr

ABSTRACT The combination of phosphorus and zinc is mainly used as the carbon steel corrosion inhibitor for cooling water systems in the industrial plants such as petroleum refining or petrochemical plants. Moreover, treatments with high-concentration phosphorous and zinc are also applied to inhibit initial corrosions when the industrial plants are started up. Recently in some countries such as China, using phosphorous is prohibited by the wastewater regulation because of increasing conscious for environment. Therefore, non-phosphorus treatments for cooling water systems are highly required. In

Extended Abstract Zinc coatings applied to steels may corrode in place of substrate to form protective oxides that protect the substrate. However, in humid environments, the protective oxide does not form properly, what is aggravated by the chloride ions presence. Many cyclic accelerated corrosion tests use high concentrations of chloride ions, resulting in the formation of soluble zinc salts, which are removed from the surface, which may lead to results that do not adequately represent performance of galvanized steel.

Abstract Corrosion under insulation (CUI) is a significant challenge in industrial environments, particularly in the temperature range of 77-110°C according to API RP 581. Zinc-rich paint is commonly used in protective coatings for corrosion protection of carbon steel. This study investigates the behavior of zinc in simulated CUI environments at 80°C, focusing on the potential reversal phenomenon between zinc and carbon steel. Corrosion potentials of zinc and carbon steel were measured in solutions simulating anions leached from insulation materials. Additionally, electrochemical behavior of t

Abstract Traditional organic coatings which provide cathodic protection such as zinc-rich coatings exhibit several major drawbacks. To achieve electrical conductivity zinc-rich coatings rely on tangential contact between zinc dust particles. This results in over pigmentation of the binder exceeding the critical pigment volume concentration of the resin system. This results in an inferior coating with poor physical and mechanical properties. In addition, Zinc-rich coatings limit the amount of corrosion protection they can provide. The utilization of carbon nanotechnology overcomes the issues no

Durian disease-causing organisms such as fungi can infect durian trees at any stage of development. Chemical fungicides are widely used because they are convenient and simple to use. However, it impacts the health of producers, consumers, and the environment. As a result, recommendations have been developed and established for researching zinc oxide nanoparticles (Zn-ONPs) that can inhibit fungal growth as an alternative for preventing and eliminating such fungi. The purpose of this study is to collect and isolate some fungi that cause durian diseases and their pathogenicity test, as well as t

Abstract The various coated-sheet products developed for the automotive industry include steel sheet with zinc or zinc-alloy coatings on one or both sides of the sheet. The study described here indicates that electrolytic couples may develop when water condenses within the wraps of coils of one-side-coated product or within coils having coatings of different zinc alloys on the opposite surfaces. In such instances, the zinc on the surface having the purer zinc coating will provide cathodic protection to the adjacent surface in the coil. Consequently, the one- side-coated and the differentially

Oxidation catalysts and three-way catalysts can be used to reduce the amount of CO present in engine exhaust. For 2-stroke lean-burn engines, the oxidation catalyst degrades over time be-cause of the buildup of poisons such as sulfur, zinc, phosphorous, and calcium. Three-way cata-lysts used with stoichiometric engines also degrade over time. Emissions analyzers are often used to evaluate the degradation of oxidation catalysts and three-way catalysts, but it can be very time consuming and expensive.
