Background & Aims of the Study: The main objectives of the current research were (1) to study the extent of soil pollution by heavy metals (Ag, Cd, Cr, Cu, Mn, Ni, Pb, Zn, Ba and Li) in sampling locations (2) to investigate the extent of heavy metal pollution and soil to plant transfer of these elements in wheat and barley (3) to study the health risk of heavy metals via consum...

Treatment of soils contaminated with heavy metals using plant species is a method which has been widely used in thepast. This method, which is known as phytoremediation, has been applied for pollution treatment using different plantspecies worldwide. The method has been used for remediation of various types of pollutants in laboratory, pilot andindustrial scales. The aim of this study was to co...

the use of fertilizers npk and amendments in sugar cane crops may change the heavy metalsconcentrations in soils, making them available for plants and, consequently, they can be transferred to thehuman food chain. this study describes the redistribution of heavy metals (cd, cr, cu, ni, pb and zn) in soils with sugar cane crops due to fertilizers npk and amendments at corumbataí river basin, são...

The aim of this paper was to determine the concentration heavy metals in dust samples by method analysis inductively coupled plasma optical emission spectrometry (ICP-OES) and assess degree pollution studied areas. subjected analytical analyzes were collected from vicinity industrial areas urban localities Jiu Valley, a monoindustrial area. main determined were: Cu, Zn, Pb, Ni, Cr, Co etc. Dust...

The fate and transport of mercury are of critical concern in lowland floodplains and wetlands worldwide, especially those with a history of upstream mining that increases the mobility of both dissolved and sediment-bound Hg in watersheds. A mass budget of total mercury (THg) quantifies sources and storage for particular areas - knowledge that is required for understanding of management options ...

In this study, heavy metals such as Al, Cr, Cu, Zn, Cd, Hg, Pb etc. content in liver, muscle and gill of three economical marine species [striped seabream (Lithognathus mormyrus Linneaus, 1758), two-band bream (Diplodus vulgaris Geoffroy Saint-Hilaire, 1817) and Common pandora (Pagellus erythrinus Linneaus, 1758)] obtained from 4 stations (Fethiye, Bodrum, Datça, Marmaris) in South Aegean coast...

One of the most important methods to investigate heavy metals as pollutants is more likely to use bio-monitors which can be applied as an appropriate index to express the quality of environment. In current study, in order to investigate the effects of dominant plants in the desired region and role of aquatic macrophytes in monitoring such elements as zinc (Zn), lead (Pb), copper (Cu) and cadmiu...

Background: Due to environmental contamination in recent years, contamination of food chain by heavy metals is not far-fetched. The purpose of this study is to determine heavy metals in soybeans cultivated in Iran to monitor the food chemical contaminants. Methods: To assess metal contamination, four varieties (Sahar, Katool, Williams, and M7) of soybean cultivated in Iran, were collected. Met...

Juvenile hybrid tilapia (Oreochromis sp.) was tested with different concentration of heavy metals under varying exposure time to examine acute toxicity effect on their survival rate and bioaccumulation in fish tissues. Copper (Cu), cadmium (Cd) and zinc (Zn) was used at rates 0.0, 0.50, 1.0, 3.0 and 5.0 mg L-1. The medial lethal concentration of Cu, Cd and Zn (96h LC50) was determined to be 0.4...

Vegetable fields near villages in China are suffering increasing heavy metal damages from various pollution sources including agriculture, traffic, mining and Chinese typical local private family-sized industry. 268 vegetable samples which included rape, celery, cabbages, carrots, asparagus lettuces, cowpeas, tomatoes and cayenne pepper and their corresponding soils in three economically develo...
