TLDR
Bioavailability is the key to understanding the risks from pollution and to defining remediation strategies, since organisms only respond to the fraction that is biologically available.Abstract:
Bioavailability is the key to understanding the risks from pollution and to defining remediation strategies, since organisms only respond to the fraction that is biologically available. Plants are able to uptake the substances only if present in available forms in the soil environment; this means that bioavailability is the key to evaluating the feasibility of phytoextraction as a remediation technology.read more

Mitigation of arsenic accumulation in rice: An agronomical, physico-chemical, and biological approach–A critical review
TL;DR: In this paper, an urgent need to either remediate As contaminated paddy soils, or to screen for low As accumulating rice varie... human exposure to As through rice consumption is a worldwide health concern.

Inoculation with abscisic acid (ABA)-catabolizing bacteria can improve phytoextraction of heavy metal in contaminated soil.
TL;DR: It is demonstrated that Rhodococcus qingshengii can increase the accumulation of Cd, Zn, and Ni in plants via an ABA-mediated HM transporters-associated mechanism, and that metabolizing ABA might be indispensable for R. qinghengii to improve metal accumulation in plants.

Arbuscular mycorrhizal wheat inoculation promotes alkane and polycyclic aromatic hydrocarbon biodegradation: Microcosm experiment on aged-contaminated soil☆
TL;DR: The results demonstrated that the inoculation of wheat with Rhizophagus irregularis allowed a better dissipation of PAHs and alkanes after 16 weeks of culture by comparison to non-inoculated condition, and suggested that mycorrhization led to a better hydrocarbon biodegradation in the aged-contaminated soil.

Soil particle size fraction and potentially toxic elements bioaccessibility: A review
TL;DR: In this article, a review of the relation between PTE bioaccessibility and soil particle size fractions is provided, which indicates a general trend of higher bio-accessibility in finer size fraction was found.
Journal ArticleDOI
Screening of Indigenous Ornamental Species from Different Plant Families for Pb Accumulation Potential Exposed to Metal Gradient in Spiked Soils
TL;DR: In this paper, the authors explore ways to remediate contaminated surface soils with lead (Pb) in order to solve the problem of lead contamination in surface soil with Pb.

Regulation and function of root exudates.
TL;DR: This review focuses on compiling the information available on the regulation and mechanisms of root exudation processes, and provides some ideas related to the evolutionary role ofRoot exudates in shaping soil microbial communities.
Journal ArticleDOI
Aging, bioavailability, and overestimation of risk from environmental pollutants
TL;DR: As they persist, or age, in soil, organic compounds become progressively less available for uptake by organisms, for exerting toxic effects, and for biodegradation and bioremediation by microorganisms.

Root exudates as mediators of mineral acquisition in low-nutrient environments
TL;DR: The current understanding of how plants use root exudates to modify rhizosphere pH and the potential benefits associated with such processes are assessed are assessed in this review.
