There is a worldwide increase of heavy metal or potentially toxic element (PTE), contamination in agricultural soils caused mainly by human and industrial action, which leads to food contamination in crops such as in maize. Cadmium (Cd) is a PTE often found in soils and it is ingested through food. It is necessary to determine the bioabsorption, distribution, and accumulation levels in maize to...

Organochlorine pesticides such as DDT and HCH had been abundantly produced and used since the around twentieth century in all over the world and environmental pollution, food contamination and human body pollution had developed into social problem because of their high bioconcentration potential and high persistency. The use and manufacturing of DDT and HCH were forbidden in many countries incl...

as a result of human activities, metal pollution has become one of the most serious environmental problems today. phytoremediation utilizes plants to uptake contaminants and can potentially be used to remediate metal-contaminated sites. a pot experiment was conducted to compare the phytoextraction and phytostabilization potential of two plant species (populus alba and morus alba) for some eleme...

. The metal bioaccumulation potential of selected macroalgae species as different pH ranges were study for usage as part of a possible secondary passive AMD treatment technology in algae ponds in temperate regions during winter months. . Two separate studies were conducted to determine the suitability of macroalgae for passive treatment when metabolic processes in macrophytes and microrganisms ...

Water pollution is one of the global challenges that society must address in 21st century aiming to improve water quality, reduce human pollutants and ecosystem health impacts. In phytotoxicity test, plant Iresine herbstii was exposed remove nickel from simulated wastewater using two different ratios (mass mass nickel) (,Rp/Ni) for 21 days with sub-surface batch system. During exposure period, ...

This study aimed to assess the phytoremediation potential of Ricinus communis L. for heavy metals remediation via rhizospheric bacterial activities distillery wastewater detoxification and management. Results revealed that contained high levels other physico-chemical pollution parameters could cause environmental aquatic toxicity. The identified bacterium produced several plant growth-promoting...

Abstract Background and aims Cadmium (Cd) contamination is a serious threat to plants humans. Silicon (Si) was reported have some alleviative effects on Cd stress in plants. However, whether Si alleviates toxicity maize genotypes with contrasting root system size are unknown. Methods Effects of application (200 mg kg ?1 soil) shoot growth, uptake transportation under (20 were assessed at the si...

This study was undertaken to evaluate the phytoremediation potential of Ficus Benjamina plant for removal polycyclic aromatic hydrocarbons (PAHs): Acenaphthene (ACN), naphthalene (NAP) and phenanthrene (PHE) from contaminated soil. The transplanted into pot containing 4 kg soil spiked with PAHs: ACN, NAP PHE at concentrations 1600, 2000 2400 mg respectively. A separate untreated used as a contr...
