Special Issue Information

Dear Colleagues,

Mass spectrometry is one of the most technologically driven research areas that has been successfully applied to the identification of almost all types of compounds. It is versatile, efficient, and sensitive, and has essential characteristics for the identification of unknown compounds, even at trace level. These can be found in a wide range of areas, such as the environment, where the nature and identity of contaminants in water, air, and soils are a priority due to the strong implications they may have on human health, as well as their risk to aquatic organisms.

Dioxin-like compounds, atmospheric polycyclic aromatic hydrocarbons, emerging contaminants, are just a few examples of priority pollutants that can be found in air, water, and soils. Their detection, identification, and quantification, as well as the development of degradation procedures for these compounds, together with the identification of the resulting degradation products are of major importance. For this, mass spectrometry and hyphenated techniques mass spectrometry-based, such as GC-MS, LC-MS, and MS-MS, are of the utmost importance.

This Special Issue will publish contributions from researchers in the field of mass spectrometry applied to the environment, which review and discuss the most current methodologies used for the identification of contaminants and their transformation products. Particular emphasis should be focused on new methodologies that involve pollutant transformation and identification/characterization procedures involving mass spectrometry.

I would like to invite you to submit original research papers to the Special issue “Mass Spectrometry and Analytical Techniques in the Environment”.

Acidic soils can promote the bioavailability of Al, Mn, and Fe to toxic levels, reducing crop growth and productivity. Symptoms of metal excess/deficit are dependent on the chemical composition of the soil solution and of plant tissues. In the present study, the concentration and subcellular distribution of Al, Mn, Fe, and Si (known to alleviate metal stress) were quantified through inductively coupled plasma mass spectrometry (ICP-MS) in roots and shoots of wheat grown in acidic soils with rising levels of Mn. In control acidic soil, wheat showed high concentrations of Al, Mn, and Fe. After Mn supplementation, bioavailable Al, Fe, and Si levels increased in the soil solution, but plant uptake ratio decreased. Root Mn levels increased, while those of Al, Fe, and Si decreased. Although elements were increasingly translocated to the shoot, root Al and Fe concentrations were 10-fold higher than those in the shoot. At the highest Mn concentration supplied, Al, Fe, and Si proportions increased in the organelles, while Mn proportion increased in the vacuole. High bioavailable Mn levels disrupt metal homeostasis in wheat grown in acidic soils, influencing element subcellular distribution. Symptoms of metal toxicity result from interactions between several elements, and therefore a comprehensive chemical analysis of soil solution and plant tissues contributes to a more accurate understanding of their uptake dynamics and their agronomic implications.
