The programs of managing waste materials in developing countries are often unsatisfactory and the unreasonable disposal of waste is a major issue in the worldwide. The main aim of the current study is to: Assess the applicability of Rumex crispus L. in removing heavy metals from the contaminated wastewater effluent form Pharmaceutical laboratories by bio-adsorption method. The dried R. crispus ...

Aims: to investigate and to compare the variation of the bioaccumulation of heavy metals (Cr, Cd, Fe, Mn, Pb and Zn) by two different molluscs species and also heavy metal concentration in sea water and sediment in Timsah Lake-Suez Canal. And finally to study the correlation between metal concentrations in different size classes of each molluscan species. Study Design: Levels of the heavy metal...

The increasing prevalence of environmental pollution, especially soil contamination with heavy metals has led to their uptake in the human food chains through plant parts. Accumulation and magnification of heavy metals in human tissues through consumption of herbal remedies can cause hazardous impacts on health. Therefore, chemical profiling of nine heavy metals (Mn, Cr, Pb, Fe, Cd, Co, Zn, Ni ...

Therefore fruits and vegetables are very useful for the maintenance of health as a preventive treatment of various diseases (D’ mello, 2003). The presence of heavy metals may have a negative influence on the quality of vegetables and fruits causing changes to their taste and smell. The term heavy metals to any metallic elements that has a relative density greater than 4gcm -3 . In the group of ...

There is an increasing concern about heavy metal contamination in farmland in China and worldwide. In order to reveal the spatial features of heavy metals in the soil-rice system, soil and rice samples were collected from Nanxun, Southeastern China. Compared with the guideline values, elevated concentrations of heavy metals in soils were observed, while heavy metals in rice still remained at a ...

ABSTRACT The lethal threats to human health from heavy metals are associated with untreated ground water. We developed a high throughput single step heavy metal purification process based on Ion Concentration Polarization mechanism. Instead of microfluidic channel networks, the plastic prototype made of plastic meshes and Nafion nanoporous material was built so that the manufacturability and co...

Background & Aims of the Study: Leachate production is a major problem for solid waste landfills and causes important threat to health public and environment. One of the typical properties of heavy metals is that they cannot easily decompose in the environment. The aim of this study was to measure of heavy metals concentrations in old-age leachate from Qazvin landfill site, Ira...

The purpose of this work was to provide information on heavy metals concentration in soils and in irrigation water in Thessaly, Central Greece, where tobacco (Nicotiana tabacum) is cultivated. Tobacco tends to accumulate high levels of heavy metals, especially Cadmium. During the years 1998, 1999 and 2000, 795 surface soil samples (0-30 cm depth) and 200 water samples were collected from Kardit...
