Phytoremediation efficiencies of Brassica napus and Chenopodium quinoa in experimental soils contaminated with Pb using chelator complexes

Arbuscular mycorrhizal phytoremediation of soils contaminated with phenanthrene and pyrene.

An available remediation technique--arbuscular mycorrhizal phytoremediation (AMPR)--is further proposed for soils contaminated with phenanthrene and pyrene as representative polycyclic aromatic hydrocarbons (PAHs) utilizing a greenhouse pot experiment. The initial concentrations of phenanthrene and/or pyrene in soils were 103 mg kg(-1) and 74 mg kg(-1), respectively. The host plant was alfalfa ...

Distribution of minerals in quinoa (Chenopodium quinoa Willd.) seeds.

The distribution of minerals in quinoa (Chenopodium quinoa Willd.) seed was examined using energy dispersive X-ray microanalysis (EDX) in combination with scanning electron microscopy (SEM). Phosphorus, K, and Mg coincided in localization in embryonic tissue. Since phytin globoids have been known to localize in protein bodies in embryonic cells of quinoa seed, it is thought that P is attributed...

Recent advances in phytoremediation of arsenic-contaminated soils

Arsenic contamination in soils occurs widely in a range of ecosystems resulting from geological origins and anthropogenic activities. On average, arsenic concentration ranges from 5 to 10 mg kg−1 in uncontaminated soils and above 10 mg kg−1 in contaminated soils (Hossain, 2006). Increased buildup of arsenic in irrigated soils has been widely recognized in South and South-east Asia (Brammer and ...

Phytoremediation of contaminated soils and groundwater: lessons from the field.

BACKGROUND, AIM, AND SCOPE The use of plants and associated microorganisms to remove, contain, inactivate, or degrade harmful environmental contaminants (generally termed phytoremediation) and to revitalize contaminated sites is gaining more and more attention. In this review, prerequisites for a successful remediation will be discussed. The performance of phytoremediation as an environmental r...
