Iron and zinc

This paper aims to evaluate the spatiotemporal distribution of six heavy metals (arsenic - As, cadmium - Cd, mercury - Hg, lead - Pb, zinc - Zn, and iron - Fe) in water and sediment environment and assess the pollution status of the heavy metals based on individual metals and overall metal contamination levels as well as a multiple metals index for the monitoring and sustainable management of estuarine environment of Ba Ria-Vung Tau Province.

This test method covers procedures for determining the weight [mass] of coating on iron or steel sheet, wire, and other articles in which the coating is zinc or a zinc alloy, such as zinc-5 % aluminum (including zinc-5 % aluminummischmetal and zinc-5 % aluminum-0.1 % magnesium), zincaluminum-magnesium (including zinc-5 to 9 % aluminummagnesium and zinc-9 to 13 % aluminum-magnesium) or 55 % aluminum-zinc. In the body of this test method, reference to zinc coating shall be interpreted to also include zinc alloy coating except where specifically stated otherwise.

"Standard Specification for Zinc Coating (Hot-Dip) on Iron and Steel Hardware" covers zinc coatings applied by the hot-dip process on iron and steel hardware. The hot-dip galvanizing process consists of parts being immersed in molten zinc for a sufficient time to allow a metallurgical reaction between iron from the steel surface and the molten zinc, resulting in the formation of Zn/Fe alloy layers bonding the coating to the steel surface.

Rice (Oryza sativa L.) is one of the major food crops but is deficient in minerals such as Zn. In rice, there were eight genes belonging to the Natural resistance-associated macrophage protein (NRAMP) family, of which OsNRAMP1, OsNRAMP4, OsNRAMP5, OsNRAMP6, and OsNRAMP8 were reported to transport metals such as iron (Fe), zinc, mangan (Mn).

Grain zinc and iron concentration is a complex trait that is controlled by quantitative trait loci (QTL) and is important for maintaining body health. Despite the substantial effort that has been put into identifying QTL for grain zinc and iron concentration, the integration of independent QTL is useful for understanding the genetic foundation of traits.

Ferrous iron (Fe) and zinc (Zn) at high concentration in the soil cause heavy metal toxicity and greatly affect rice yield and quality. To improve rice production, understanding the genetic and molecular resistance mechanisms to excess Fe and Zn in rice is essential. Genome-wide association study (GWAS) is an effective way to identify loci and favorable alleles governing Fe and Zn toxicty as well as dissect the genetic relationship between them in a genetically diverse population.

The C2H2 zinc finger protein ZAT12 has been classified as a plant core abiotic stress response gene in the early response to multiple stresses. ZAT12 links the iron deficiency and oxidative stress responses through the direct interaction with/and negative regulation of a central regulator - FIT. For further research on the regulation of the ZAT12 protein in planta, a huge quantity of ZAT12 proteins is required to inject into mice for the generation of ZAT12 antiserum.
