“…Earlier papers published beneficial information on the metal accumulation potential of members of the Salicaceae family, out of which Populus (poplar) is a thoroughly mapped genus in this regard (Guerra et al 2011;Marmiroli et al 2011). The advantages of this genus over other genera with rapid growth and high biomass production rate (e.g., Brassica and Sorghum species) are its high biomass, soil stabilization effect due to the deep root system, continuous metal accumulation, and applicability in short rotation coppice (SRC) management even in the long term at the same time, favoring its common use for phytoremediation purposes (Chandra et al 2016;Villette et al 2019).…”

Populus species are well documented for being potentially suitable for phytoremediation purposes regarding their accumulation characteristics. However, published results are contradictory. Based on the data gathered during an extensive literature search, we aimed to assess and revise the metal accumulation potential in the root, stem, and leaf of Populus species growing in contaminated soils, with meta-analysis. We evaluated the influences of pollution level, soil pH, and exposure time on the metal uptake patterns. We found accumulations of Cd, Cr, Cu, Pb, and Zn to be significant in each plant part, while that was only moderate for Ni, and limited for Mn. By calculating the soil pollution index (PI), we observed significantly intensive, PI-independent accumulation for Cd, Cr, Cu, Ni, Pb, and Zn. A decrease in soil pH significantly increased the uptake of Mn and significantly decreased the accumulation of Pb in the stem. Metal uptake was significantly influenced by exposure time as well; Cd concentration was significantly decreased in the stem, while concentrations of Cr in the stem and leaf, and Mn in the stem were significantly increased with time. These aforementioned findings support a well-founded metal-and-growth condition-specific application of poplars in phytoremediation processes, also triggering further in-depth assessments to enhance the efficiency of relevant poplar-based technologies.

“…Samples were analysed by LC coupled with HRMS using a DioneX Ultimate 3000 (Thermo, Massachusetts, USA) coupled to a Q-TOF Impact II (Bruker, Bremen, Germany) using the TargetScreener method (Bruker), which allows targeted identification of micropollutants using a database containing 2072 pollutants (848 pesticides and 1224 toxicants), their retention time, their exact mass and the exact mass of their fragments in broad-band collision-induced dissociation (bbCID) fragmentation mode. Samples were analysed on a C18 column (Acclaim TM RSLC 120 C18, 2.2 µm, 120 A, 2.1 × 100 mm 2 , Dionex bonded silica products) equipped with an Acquity UPLC® BEH C18 pre-column (1.7 µm, 2.1 × 5 mm 2 ) using a gradient of solvent A (H 2 O:MeOH 90:10, 0.01% formic acid, 314 mg L −1 ammonium formate) and solvent B (MeOH, 0.01% formic acid, 314 mg L −1 ammonium formate) as described in detail by Villette et al 46 . The spectrometer was operated in positive ion mode using bbCID fragmentation mode in a mass range from 30 to 1000 Da, with a spectra rate of 2 Hz.…”

In human society, there is a demand for sustainable solutions for water preservation and efficient treatment systems. An important water reservoir is road runoff defined as rainwater leaching from roads, loading micropollutants and infiltrating the soil. We aimed to study this poorly understood feature using large-scale metabolomic analysis coupled with analysis of soil physico-chemical properties and molecular chemical similarity enrichment. A total of 2406 micropollutants were assayed to understand their distribution and assess the trapping abilities of a road runoff infiltration system composed of a sedimentation pond and an infiltration pond. Here, we confirm the essential role of the infiltration pond in preventing environmental contamination and propose a model correlating micropollutant abundance and the soil physico-chemical properties. We demonstrate that sand in infiltration ponds is a key player, helping retain 86% of the micropollutant abundance and propose a model that could be easily applied for road runoff management.

Mass spectrometry imaging for biosolids characterization to assess ecological or health risks before reuse

et al. 2023

Biosolids are byproducts of wastewater treatment. With the increasing global population, the amounts of wastewater to be treated are expanding, along with the amounts of biosolids generated. The reuse of biosolids is now accepted for diversified applications in fields such as agriculture, engineering, agro-forestry. However, biosolids are known to be potential carriers of compounds that can be toxic to living beings or alter the environment. Therefore, biosolid reuse is subject to regulations, mandatory analyses are performed on heavy metals, persistent organic pollutants or pathogens. Conventional methods for the analysis of heavy metals and persistent organic pollutants are demanding, lengthy, and sometimes unsafe. Here, we propose mass spectrometry imaging as a faster and safer method using small amounts of material to monitor heavy metals and persistent organic pollutants in different types of biosolids, allowing for ecological and health risk assessment before reuse. Our methodology can be extended to other soil-like matrices.
