“…One study aims to find a viable method of direct water determination by combining dispersive liquid–liquid microextraction with solid-phase extraction to prepare samples for the graphite furnace . Another method sometimes used for its uniquely nondestructive testing is magnetic resonance imaging (MRI) alongside high-resolution magic angle spinning nuclear magnetic resonance (HR-MAS NMR) to observe changes in metabolites of polluted samples .

Arsenic is a naturally occurring element with a long history of toxicity. Sites of contamination are found worldwide as a result of both natural processes and anthropogenic activities. The broad scope of arsenic toxicity to humans and its unique interaction with the environment have led to extensive research into its physicochemical properties and toxic behavior in biological systems. The purpose of this review is to compile the results of recent studies concerning the metalloid and consider the chemical and physical properties of arsenic in the broad context of human toxicity and phytoremediation. Areas of focus include arsenic's mechanisms of human toxicity, interaction with plant systems, potential methods of remediation, and protocols for the determination of metals in experimentation. This assessment of the literature indicates that controlling contamination of water sources and plants through effective remediation and management is essential to successfully addressing the problems of arsenic toxicity and contamination.

“…By using the comet assay, Lin et al ( 2008 ) proved that arsenate (10 μM) induced DNA damages in V. faba leaves and roots, in a dose-dependent manner and that these effects were associated with oxidative stress. Sturchio et al ( 2011 ) confirmed As genotoxicity in V. faba roots grown on sandy and clay-loamy soil spiked with arsenate. In the same species, Boccia et al ( 2013 ) combined the comet assay with infrared (FTIR), and near infrared (FTNIR) spectroscopy, to show that arsenate (20 and 30 mg/L) induced DNA damages which were associated with structural changes of different functional groups, suggesting the possible replacement of phosphate by arsenate in DNA.…”

The use of comet assay in plant toxicology: recent advances

The systematic study of genotoxicity in plants induced by contaminants and other stress agents has been hindered to date by the lack of reliable and robust biomarkers. The comet assay is a versatile and sensitive method for the evaluation of DNA damages and DNA repair capacity at single-cell level. Due to its simplicity and sensitivity, and the small number of cells required to obtain robust results, the use of plant comet assay has drastically increased in the last decade. For years its use was restricted to a few model species, e.g., Allium cepa, Nicotiana tabacum, Vicia faba, or Arabidopsis thaliana but this number largely increased in the last years. Plant comet assay has been used to study the genotoxic impact of radiation, chemicals including pesticides, phytocompounds, heavy metals, nanoparticles or contaminated complex matrices. Here we will review the most recent data on the use of this technique as a standard approach for studying the genotoxic effects of different stress conditions on plants. Also, we will discuss the integration of information provided by the comet assay with other DNA-damage indicators, and with cellular responses including oxidative stress, cell division or cell death. Finally, we will focus on putative relations between transcripts related with DNA damage pathways, DNA replication and repair, oxidative stress and cell cycle progression that have been identified in plant cells with comet assays demonstrating DNA damage.

“…However, MRI has been used to measure water, [41] fat, [42] other metabolites of plant vegetation and fruit, [43][44][45][46] and to study plant morphology, histochemistry, development, and cell metabolism. [47,48] Metals including Co, Fe, Gd, Ni, Mg, Li, Cu, Cr, and Mn, and diatomic gases such as O₂ and NO are paramagnetic and can potentially be used as MRI contrasting agents because their unpaired electrons align with and enhance external magnetic fields (positive magnetic susceptibility), decreasing the relaxation time constants, and consequently increasing NMR signal intensity.…”

The goal of this research was to visualize the uptake of copper by plants to promote phytoremediation. The hypothesis was that regions of the plant that contain more copper have enhanced nuclear magnetic resonance using copper as a paramagnetic contrast agent. Earth field magnetic resonance imaging (EFMRI) spectrometry uses a magnetic field 300,000 times weaker than a 600 MHz nuclear magnetic resonance spectrometer. As in conventional human MRI, this portable instrument is capable of recording one, two, and three dimensional images, although the sample size is reduced. The enhancement of signal was first demonstrated recording the two dimensional images of different concentrations of aqueous copper sulfate. The study also focused on growing mesquite and soybean plants in hydroponic media containing 0.25 mM copper nitrate for four and three weeks, respectively, and recording their EFMRI images with plants grown without copper nitrate. The results showed that EFMRI allows the probing the plant absorption of copper without having to dissect the specimen and therefore requires less sample preparation and time than current techniques. This technique may be beneficial to phytoremediation by imaging plants to evaluate their copper accumulation.
