A simple, efficient and cost effective method was developed and optimized for the digestion of fish tissue for the determination of Lead, Cadmium, Mercury, Antimony, Arsenic and Selenium by FAAS, CVAAS and HGAAS. Three of the more common classical open tubed acid digestion procedures were explored with the purpose of optimizing the variables and selecting the single most efficient, convenient a...
During last century, waste water of gold mine has accumulated heavy metals such as lead, zinc and cadmium in Zarshuran region soil, and thus has increased epidemic disease in this region drastically. The purpose of this research was to reduce the mobility and bioavailability of zinc, lead and cadmium in rhizosphere of sunflower grown in soil around the mine by inorganic sorbents. A pot experime...
introduction due to mining, considerable amounts of heavy metal bearing mineralsare scattered in the atmosphere in the form of dust and make the surrounding air, water and soils polluted.runoff water movingfrom the mountainstowardsplains may also transport heavy metals from mines to the soils.one type ofpollutions is contamination withheavy metals.the purpose of the present research has been to...
Effect of Municipal Wastewater on the Accumulation of Heavy Metals Cadmium and Lead in Soil and Corn
Background and Objective: Using wastewater as a renewable water source to irrigate plants is a safe and effective solution. In contrast, the accumulation of heavy elements in soil and plants is one of the concerns of the use of wastewater in agriculture. This study was conducted to investigate the effects of urban wastewater use on the most important physiological parameters related to the grow...
