during recent years there has been increasing consciousness of, and concern about, groundwater water pollution and monitoring in iran. in this context, a comprehensive review of the trace elements and heavy metals in groundwater of oshtorinan plain in northern part of boroujerd has carried out to investigate the effects of weathering minerals, agricultural and industrial activities. groundwater...

The new approaches of the animal production systems make managing the mineral nutrition a challenge. Versus the excessive, trace mineral supply in intensively managed livestock, well above the physiological requirements, is the no trace mineral supplementation of organic systems, which become highly dependent on trace minerals in the soil. Nowadays, in addition to the animal health perspective,...

This article illustrates the importance of having analytical data on the vitamin and mineral contents of dietary supplements in nutrition studies, and describes efforts to develop an analytically validated dietary supplement ingredient database (DSID) by a consortium of federal agencies in the USA. Preliminary studies of multivitamin mineral supplements marketed in the USA that were analyzed as...

The Zambezi River rises at the center of southern Africa, flows across low-relief Kalahari Plateau, meets Karoo basalt, plunges into Victoria Falls, follows along rifts, and pierces through Precambrian basement to eventually deliver its load onto Mozambican passive margin. Reflecting polyphase evolution, river is subdivided segments with different geological geomorphological character, a subdiv...

Medicinal plants form the basis of sophisticated traditional medicine system that has been in existence for thousands of years, which continue to provide mankind with new remedies. Herbal plants are consumed worldwide for the treatment of several diseases and such plants are the important source of raw material for pharmaceutical industries. As a micronutrient, heavy metal plays an essential ro...

Heavy metals transport to groundwater relies on the characteristics of soil, such as carbonate and clay minerals, organic matter content, soil pH, some other factors. Most heavy in calcareous soils are precipitated metal minerals; consequently, their is not anticipated. Therefore, current study focused impacts calcium presence adsorption lead (Pb) copper (Cu) using batch column experiments. To ...
