Trace elements account for about 0.1% of the human body and are also crucial for the existence of lower organisms, being necessary for proper development, cell metabolism, reproduction, and immune function. WHO categorizes trace elements into three groups: essential, probably essential, and ...
Trace elements concentrations in aquatic biota from the Iron Gates wetlands in RomaniaHeavy metalswetlandsfishplantsmolluscsConcentration of four heavy metals was studied in living organisms from the wetlands ecosystems within the Iron Gates Natural Park in Romania. Samples included aquatic plants (...
Over 100 years ago, macro-scale analytical techniques were used to discover the roles of special compounds (especially of metallic elements) in living organisms, and investigations were focussed on selected proteins and pigments suspected of containing percentage quantities of metals. In contrast, presen...
Living organisms, naturally occurring in human environment, gained in the last decade, increasing interest in analytical chemistry. This review presents the application of bacteria, yeast, algae, and fungi for the preconcentration of heavy metals from environmental samples. The specific bonding sites on...

Trace elements in agricultural subsurface drainage water may bioaccumulate in wildlife through their feeding on organisms living in evaporation ponds or other habitats that receive the drainage water. Selenium is the element of greatest concern, but arsenic, boron, and molybdenum also are discussed brie...
摘要: Trace elements are vital for the operation of metabolic pathways that promote growth and structural integrity. Trace elements are essential for plant growth, i.e., iron, zinc, copper, manganese,...DOI: 10.1007/978-981-15-8636-1_6 年份: 2020 ...
This study aimed to characterize the water quality of 4 sites in Lake Idku, the third largest wetland region in Egypt regarding the physicochemical indicators, the spatial distributions of certain trace elements and organochlorine compounds (OCs). Most of the tested water quality indicators were above...
This article presents a method of obtaining biologically acceptable and effective trace elements in the form of aqueous dispersions of metals. A complex compound was prepared, which includes metal nanoparticles in particular, such as iron (Fe)—1800 ppm; copper (Cu)—400 ppm; zinc (Zn)—1000 ...
