Kaolinite is non-sensitive, low swelling clay with high chemical resistance and high workability. It is commonly found as a major fraction of clay liner in waste disposal sites. These clay liners are usually exposed to different concentrations of heavy metals. Even though there are several researches focusing on the interaction process of kaolinite and heavy metal contaminations, there are only...
Background and Objectives: Heavy metal pollution has always been a major cause contamination of environment and considered as a major concern for food health. Rice is the most popular food among Iranians and presence of heavy metals in trace level in rice has received special attention because they are directly related to health.The aim of this research was to investigate the concentration of P...
To solve the water pollution problem by toxic heavy metal contamination resulting from humans technological activities has for long presented a challenge. Biosorption can be a part of the solution. Some types of biosorbents such as seaweeds, molds, yeasts, bacteria or crab shells are examples of biomass tested for metal biosorption with very encouraging results. The uptake of heavy metals by bi...
In this issue, Singh and colleagues[1] highlight the persistent international problem of heavy metal contamination, particularly lead, in traditional medicine products (TMPs). Certain TMPs from Asia, Latin America and the Middle East have all been associated with lead poisonings.[2] With travel and migration, contaminated TMPs have resulted in heavy metal intoxications in persons residing in co...
Heavy metal contamination of aquatic environment has attracted global attention owing to its abundance, persistence, and environmental toxicity, especially in developing countries like Bangladesh. Five heavy metals, namely chromium (Cr), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) were investigated in surface and core sediments of the Karnaphuli River (KR) estuary in Chittagong, Banglades...
Background: Non-biodegradation in nature and the creation of adverse health effects in humans is important features of heavy metals. The main purpose of this study was to determine the carcinogenic and non-carcinogenic risks of heavy metals As, Cd, Cu, Cr, Pb, Ni, V, and Zn in the soils of industrial areas of Mahshahr port for adults and children. Methods: To study the environmental effects of ...
ría and coastal zone are, in particular, vulnerable to heavy metals pollution. concentrations of 10 metals in liver, muscle and kidney of the sole (solea vulgaris) from ría of vigo and its coastal zone (spain) were measured from april 2006 to february 2007 and the relationships between fish size age and metal concentrations in the tissues was investigated. concentrations of the heavy metals in...

This paper reviews contamination status, sources and remediation of heavy metals in agricultural land of most Asian countries, with an emphasis to China, which are undergoing rapid economic development. Some farmland soil in suburbs of most cities and sewage irrigation district in China are polluted to some extend with heavy metals such as Cd, As, Zn, Cu, and Hg, consequently resulting in metal...
Urbanization, industrialization and agricultural practices have resulted in soil contamination with heavy metals in many world areas. Phytostabilization is an emerging solution to limit pollutant dispersion out of the contaminated area without expensive costs (Vangronsveld et al., 2009). However, because of the heavy metal phytotoxicity, the implementation of a plant cover could be jeopardized....
