Their spread in the environment can affect both plant and animal health. Ecohydrology serves as a solution for assessment approaches (i.e., threat identification, ecotoxicological assessment, and cause–effect relationship analysis) and solution approaches (i.e., the elaboration of nature-based solutions: NBSs), mitigating the toxic effect of CECs. However, the wide array of potential molecular analyses are not fully exploited in ecohydrological research. Although the number of publications considering the application of molecular tools in freshwater studies has been steadily growing, no paper has reviewed the most prominent studies on the potential use of molecular technologies in ecohydrology. Therefore, the present article examines the role of molecular methods and novel omics technologies as essential tools in the ecohydrological approach to CECs management in freshwater ecosyste...

The experiment was performed for 4 weeks in a growth chamber under controlled conditions. Amendment of Hudson River sediment to soil led to a gradual increase in PCB content of the substratum from 13.7 μg/kg (with 10% sediment) to 255 μg/kg (with 100% sediment). Sediment amendment showed no phytotoxic effects during the initial stages, even Lepidium sativum root growth was stimulated; however, this positive response diminished following a 4-week growth period, with the greatest inhibit...

The aim of this study was to investigate the effect of selected PSMs (ferulic acid—FA; syringic acid—SA) on the removal of structurally-similar phenoxy herbicides (PHs): 2,4-dichlorophenoxyacetic acid (2,4-D) and 2-methyl-4-chlorophenoxyacetic acid (MCPA). The study also examines the biodegradation potential of soil bacteria, based on the occurrence of functional tdfA-like genes, and the ecotoxicity of the samples against two test species: Sinapis alba L. and Lepidium sativum L. The microbial cultures spiked with the PSMs demonstrated higher phenoxy acid removal: 97–100% in the case of 2,4-D and 99%–100% for MCPA. These values ranged from 5% to 100% for control samples not amended with FA or SA. The higher herbicide removal associated with PSM spiking can be attributed to acceleration of the microbi...

Microorganisms can degrade almost all organic pollutants, but this process might be very slow in some cases. A promising way to enhance removal of recalcitrant xenobiotics from the environment lies in the interactions between plant exudates such as plant secondary metabolites (PSMs) and microorganisms. Although there is a considerable body of evidence that PSMs can alter the microbial community composition and stimulate the microbial degradation of xenobiotics, their mechanisms of action remain poorly understood. With this in mind, our aim was to demonstrate that similarity between the chemical structures of PSMs and xenobiotics results in higher micropollutant degradation rates, and the occurrence of corresponding bacterial degradative genes. To verify this, the present study analyses the influence of syringic acid, a plant secondary metaboli...

The study examine the impact of fertilizing poor quality soil with sewage sludge from three sizes of wastewater treatment plants (WTP) (small, medium and large) located in Central Poland, applied in two doses (3 and 9tons per hectare), on biomass yield and selected biochemical parameters in willow plants. The WTPs were selected based on the size criterion given in Polish regulations. Three variables were analyzed in the leaves and roots of willow cuttings after twenty weeks of cultivation: the degree of oxidative reaction, assessed as thiobarbituric-acid-reactive substances (TBARS) content; catalase activity (CAT, EC 1.11.1.6), reflecting the efficiency of the antioxidative response; and changes in the concentration of proline, one of the major cellular osmoprotectants. For plants growing in poor-quality soil, sewage sludge administration results in a large increase of willow biomass b...

This paper reports the analyses of Cyanobacteria toxigenicity (the degree of potential toxicity) in lowland dam reservoir (Sulejów Reservoir, Central Poland) by the use of PCR-based methods. The reservoir (area 22 km2, mean depth 3.3 m) is very eutrophic water body permanently blooming with blue-green algae (mainly Microcystis aeruginosa). For identification of cyanobacterial genus the 16S rRNA region was used. Cyanobacterial genus was detected during the whole monitoring period in summer 2003. The potential toxicity of cyanobacteria was determined by amplification of selected mcyA,B,E genes in the microcystin biosynthesis pathway. All of the analyzed genes were detected at the beginning of the growing season during low cyanobacterial biomass (0.67 mg l–1). 89% of the samples were found to be positive for mcyA detection. Early detection of mcy genes at the b...

The hybrid SBS was constructed with two barriers, a geochemical (filtration beds with limestone, coal and sawdust) and a biological barrier (wetlands with Glyceria, Acorus, Typha, Phragmites), operating in parallel. Significant differences were found between inflow and outflow from the SBS with regard to wastewater contaminant concentrations, the efficiency of removal being 16% (max. 93%) for Total Phosphorus (TP), 25% (max. 93%) for Soluble Reactive Phosphorus (SRP), 15% (max. 97%) for Total Nitrogen (TN), 17% (max. 98%) for NO3(-)N, and 21% for PCB equivalency (PCB EQ). In the case of PCB EQ concentration, the highest efficiency of 43% was obtained using beds with macrophytes. The SBS remove...

The analysis also considered the effect of wastewater outflow on the final concentrations of PCDDs/Fs, as the samples were collected during flooding and stable hydrological conditions. None of the studied WTPs were found to completely remove toxic congeners of PCDDs/Fs from wastewater: the PCDD concentrations in the outgoing effluent during stable wastewater flow ranged from 2.99 to 177.19 pg/L, PCDFs from 6.05 to 51.30 pg/L, and the Toxic Equivalent (TEQ) was between 0.94 and 4.87 pg/L. The results from high wastewater flow were less diversified, ranging from 5.04 to 8.85 pg/L for PCDDs, from 11.47 to 32.33 pg/L for PCDFs and from 2.00 to 4.65 pg/L for TEQ. The smallest...

The study also evaluated the impact of this sewage sludge on the biometric and physiological parameters and detoxification reaction of willow (Salix sp.) as a typical crop used for the remediation of soil following sludge application. The cultivation of willow on soil treated with sludge was found to result in a gradual increase of humus fractions, total organic carbon content and bacterial abundance as well as soil properties measured using Lepidium sativum. However, it also produced an initial increase of soil phytotoxicity, indicated by Sinapis alba and Sorghum sacharatum, and PCDD/PCDF Toxic Equivalent (TEQ) concentrations, which the...

Although there is a considerable body of evidence that PSMs can cause changes in microbial community composition and stimulate microbial degradation of xenobiotics, the mechanisms of action on the molecular level (e.g. degradative gene induction) in relation to their chemical structure have not been fully understood yet. With this in mind, PLASMMIX aims to acquire new knowledge on the role of PSMs in the microbial degradation of structurally related xenobiotics and in the expression level of the corresponding degradative genes. In particular, the project will assess the influence of two cucurbits PSMs: cucurbitacin A and ferulic acid on the changes of the microbial community composition, presence of degradative genes and degradation efficiency of Ethinylestradiol (EE2) and 4-chloro-2 methylphenoxyacetic acid (MCPA). The expression of genes involved in the degradation pathways of EE2 and MCPA will be additionally assessed. The project relies on the interdisciplinary approach, involving integrated methodology and expertise and knowledge in environmental microbiology (metagenomics applied to the rhizosphere), microbial physiology (catabolism and assimilation of xenobiotics, gene regulation), plant physiology (PSM production), environmental chemistry (analytics and radioanalytics) as well as soil science Results will increase the knowledge in PSM-mediated xenobiotics removal and will prove valuable in designing efficient rhizoremediation strategies.
