Tolerance to Cadmium of Agave lechuguilla (Agavaceae) Seeds and Seedlings from Sites Contaminated with Heavy Metals

We investigated if seeds of Agave lechuguilla from contaminated sites with heavy metals were more tolerant to Cd ions than seeds from noncontaminated sites. Seeds from a highly contaminated site (Villa de la Paz) and from a noncontaminated site (Villa de Zaragoza) were evaluated. We tested the effect of Cd concentrations on several ecophysiological, morphological, genetical, and anatomical resp...

Bioremediation of Waters Contaminated with Heavy Metals Using Moringa oleifera Seeds as Biosorbent

Heavy Metals Contaminated Environments and the Road Map with Phytoremediation

This review presents the justification of research into heavy metals and clean-up technologies with particular emphasis on phytoremediation of heavy metals contaminated soils. The generating sectors and heavy metal contaminant contributors are reviewed alongside likely types. The new paradigm by researchers in response to negative impacts of various clean-up methodologies has been discussed. Th...

Extraction Heavy Metals from Contaminated Water Using Chelating Agents

Water pollution caused by toxic elements is one of the most important environmental problems in the world. Heavy metals are toxic to human and dangerous for the environment. The objectives of this study were: the effects of chelating agents on heavy metals extraction from polluted water were carried out to examine. In different concentrations : 0.01, 0.05, 0.1 mg/l of Chelating agents: Ethylene...

Performance of purslane (Portulaca oleracea) in nickel and cadmium contaminated soil as a heavy metals-removing crop

Specific plants can remove heavy metals from the soil and contribute to pollution remediation in cropping systems. Determining the level of highest heavy metals that a super-accumulator crop can withstand without reducing its yield is important for management. The objective of this study was to investigate the heavy metal-removing capacity of purslane by studying different stress criteria and b...
