Ren W, Wang Y, Huang Y, Liu F, Teng Y. Uptake, translocation and metabolism of di-n-butyl phthalate in alfalfa (Medicago sativa). THE SCIENCE OF THE TOTAL ENVIRONMENT 2020; 731:138974. [PMID: 32413654 DOI: 10.1016/j.scitotenv.2020.138974] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/24/2020] [Revised: 04/20/2020] [Accepted: 04/23/2020] [Indexed: 05/22/2023]
Abstract
Uptake and metabolism by plants are important biotransformation processes of organic pollutants in ecosystems. However, very limited information is currently available on the metabolism of phthalic acid esters (PAEs) in plants. In this study, alfalfa, highly efficient in phytoremediation of PAE contaminated soil, was chosen as the model to understand the fate of di-n-butyl phthalate (DnBP) in remediation plant. The results of hydroponic experiments indicated that DnBP accumulated mainly in alfalfa roots and adsorption to root epidermis might be the primary uptake mechanism. A large proportion of DnBP was subjected to apparent metabolism. De-esterification could be specified to be the predominant metabolism pathway. Mono-n-butyl phthalate (MnBP) and phthalic acid (PA) were detected as DnBP metabolites in all alfalfa roots and shoots throughout the entire exposure period. Around >90% of MnBP were distributed in cell soluble components and organelles, and MnBP gradually transferred from organelles and cell walls to soluble components as the exposure time extended. Similar to MnBP, PA located mainly in soluble components and organelles as well, while no PA existed in alfalfa cell walls. Exposure to DnBP ultimately resulted in the coexistence of DnBP and MnBP for a long term in interior plants, raising concerns on their combined potential toxicity on plant health or even ecosystem.

Abstract
Phthalates are micro-pollutants of great concern due to their negative effects on ecosystem functioning and human health. Thanks to its capability in uptake and accumulation of organic pollutants, Populus alba L. "Villafranca" clone could be a good candidate for reducing the impacts derived by the persistence of such compounds in the environment. We investigated plant response and uptake of dioctyl phthalate (DOP) by poplar, grown in hydroponics condition, for 21 days with 0, 40, and 400 μg L-1 of d4-DOP. Treated plants, after 21 days of 400 μg L-1 d4-DOP, showed an increase in root dry biomass (+ 29%) at the expense of aerial parts (- 8%) compared with control. The root development could be sustained by the increase of Mg uptake by poplar. LC-MS/MS analysis demonstrated the uptake and accumulation in roots of d4-DOP starting from day one (3.5 ± 3.29 and 7.1 ± 3.28 in 40 and 400 μg L-1 d4-DOP respectively), despite volatilization of d4-DOP was observed from nutritive solution. The chemical interaction between d4-DOP and Zn occurred in roots of plants treated with the high d4-DOP concentration, without limiting the Zn concentration in leaves. Results confirm the high tolerance of "Villafranca" clone to xenobiotic and suggest the poplar capability in d4-DOP uptake and accumulation at root level.

Abstract
An improved method for solid-phase extraction (SPE)-liquid chromatography-tandem mass spectrometry was developed to analyze eight monoalkyl phthalate esters (MPEs) in eight different kinds of porcine tissues. The tissue samples were processed using enzymatic deconjugation with β-glucuronidase, followed by SPE with Oasis MAX cartridges. A pentafluorophenyl column was first used to solve the coeluting issues of MPE isomers. The limits of detection and recoveries were 0.01-0.6 ng/g and 62.5-123.7%, respectively. The intra- and interday precisions were less than 7.1 and 9.4%, respectively. The robust method was successfully applied for the investigation of MPEs in various porcine tissue samples collected from markets in Beijing, China. The occurrence of MPEs with total concentrations of 48.0-108 ng/g was detected, and monoethylhexyl phthalate was the predominant MPE (accounting for 30-57%) in all of the porcine tissue samples. The results will be helpful in assessing the potential risks of diets that include pork.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 660:733-740.

Abstract
The indigenous microorganisms with the ability of metabolising di-(2-ethylhexyl) phthalate (DEHP) in agricultural soils and their interactions with non-degrading microbes were revealed by DNA-based stable isotope probing coupled with molecular ecological network. Aside from the previously reported DEHP degraders (family Planococcaceae and genus Sphingobacterium), five OTUs representing bacteria affiliated with genus Brevundimona, class Spartobacteria, genus Singulisphaera, genus Dyella and class Ktedonobacteria were linked with DEHP biodegradation. The analysis of the constructed ecological network based on soil microbial communities demonstrated the negative relationships between DEHP degraders and the dominant family Oxalobacteraceae in soils. Additionally, two cultivable bacteria isolated from the same soils, Rhizobium-1 and Ensifer-1, had strong capabilities in degrading DEHP but their involvement in in situ DEHP degradation was questioned, as their DNA was not labelled with 13C from DEHP. These findings provide deeper understanding on the indigenous DEHP-degrading communities and will benefit the remediation of phthalate esters contaminated soils.
