Phytoremediation is a viable strategy to remove trace metal contaminants from sewage sludge but still poorly investigated. The aim of this study was quantify the removal B. napus, juncea, H. annuus, Z. mays grown on pure sludge. Each species six different for 8 weeks and were analysed content physico-chemical characteristics. Our results confirmed that all tested supported plant growth. showed ...

The Madagascar Periwinkle, Catharanthus roseus (L.) G. Don (a valued medicinal plant) was exposed to different concentrations ofheavymetals like, CdCl, and PbCl, with a view to observe their bioaccumulation efficiency. Germination was inhibited by both the heavy metals in the seeds previously imbibed in GA, and KNO, for 24 hr. EC50 (the effective concentration which inhibits root length by 50%)...

Phytoremediation use plants to remove pollutants from the environment and render them harmless. It is an economically feasible and sustainable ways regarding to the remediation of our environment without introducing any new contaminants. Considering the vast diversity of pollutants and the different kinds of environmental conditions are two most important aspects that plants used for the remedi...

Cumulative effect of urbanization, industrialization and population growth is increasing pressure on the limited natural resources. The change in living style has aggravated the problems. Among the diverse environmental problems, the discharge of heavy metals in environment through industrial, agricultural and domestic activities is of great concern. Removal of heavy metal from environment is a...

Anthropogenic activities are resulting in an increase of the use and extraction of heavy metals. Heavy metals cannot be degraded and hence accumulate in the environment, having the potential to contaminate the food chain. This pollution threatens soil quality, plant survival and human health. The remediation of heavy metals deserves attention, but it is impaired by the cost of these processes. ...

Copper smelting and refinery factories are the final stages of a pyrometallurgical processing chain, and they cause many environmental challenges around the world. One of the most common environmental problems of these factories is toxic emissions. These toxic gases have harmful effects on the vegetation, animal species, soils, and water resources around the factories. Phytoremediation can play...

Background & Aims of the Study: Heavy metals contaminate drinking water, air and soils. It is very harmful for humans and other live organisms. Phytoremediation is one of the direct bio-remediation methods for heavy metal removal from polluted water and soils. This method is accepted environmentally, economically and aesthetically. The purpose of this study was to assess Tamari...

The hyperaccumulating ecotype of Sedum alfredii Hance is a cadmium (Cd)/zinc/lead co-hyperaccumulating species of Crassulaceae. It is a promising phytoremediation candidate accumulating substantial heavy metal ions without obvious signs of poisoning. However, few studies have focused on the regulatory roles of miRNAs and their targets in the hyperaccumulating ecotype of S. alfredii. Here, we co...

Air pollution has been becoming a necessary evil with rapid industrialization and urbanization around the world, after it results in kinds of human health problems, such as ophthalmic, respiratory and cardiovascular diseases (Brunekreef & Holgate, 2002; Giles et al., 2011; Gudmundsson, 2011; Jamrozik & Musk, 2011; Miller et al., 2007; Nandasena, 2010). The direst threat posted by air pollution ...
