Abstract The evaluation of a chemical substance's persistence is key to understanding its environmental fate, exposure concentration, and, ultimately, risk. Traditional biodegradation test methods were developed many years ago for soluble, nonvolatile, single‐constituent substances, which do not represent the wide range manufactured substances. In addition, Organisation Economic Co‐operation and Development (OECD) screening simulation fully reflect conditions into substances are released therefore, estimates degradation half‐lives can be very uncertain may misrepresent real processes. this paper, we address challenges limitations facing current scientific advances that helping both understand provide solutions them. Some these advancements include following: (1) robust deeper microbial composition, diversity, abundance ensure consistency and/or interpret variability between tests; (2) benchmarking tools reference aid in evaluations through comparison against with well‐quantified profiles; (3) analytical allow quantification parent metabolites at environmentally relevant concentrations, inform on substance bioavailability, biochemical pathways, rates primary versus overall degradation, metabolite formation decay; (4) modeling predict likelihood biotransformation, as well pathways; (5) approaches derivation more generally applicable biotransformation rate constants, by accounting physical processes system design when evaluating data. We also identify that, while such could improve certainty accuracy assessments, mechanisms they translated regulatory practice development new OECD guidelines need improving accelerating. Where uncertainty remains, holistic weight evidence required accurately assess chemicals. Integr Environ Assess Manag 2022;18:1454–1487. © 2022 Authors.

Environmental Science and Pollution Research, Journal Year: 2023, Volume and Issue: 30(30), P. 75126 - 75140

Published: May 22, 2023

The aim of the study was to determine totoxicity bisphenol A (BPA) and its derivatives (bisphenol S (BPS), F (BPF), tetrabromobisphenol (TBBPA)) due high accumulation in environment. performed analysis revealed toxicity BPA, BPF, BPS against Kurthia gibsoni, Microbacterium sp., Brevundimonas diminuta as most sensitive, reaching microbial toxic concentrations range 0.018-0.031 mg ∙ L-1. Moreover, genotoxicity assay shows ability all tested compounds increase β-galactosidase level at concentration 7.81-500 µM (in Escherichia coli, PQ37). In turn, matbolic activation bishpenols has caused enhacement cytotoxicity effect. Interestingely, highest phytotoxicity effect pointed for BPA TBBPA 10 L-1 50 L-1, which cause inhibition root growth by 58% 45%, respectively (especially S. alba saccharatum). Furthermore, analyses show BPS, significantly decrease metabolic activity human keratynoctes vitro after 24 h treatment micromolar concentrations. Simialry, impact certain bisphenols on proliferation-, apoptosis-, inflammation-related mRNA expression shown cell line. Summarizing, presented results have proved that derrivatives are able negative living orgnisms such bacteria, plants, cells, is strict related pro-apoptotic genotoxic mechanism action.

Negative public sentiment built up around bisphenol A (BPA) follows growing awareness of the frequency this chemical compound in environment. The increase air, water, and soil contamination by BPA has also generated need to replace it with less toxic analogs, such as Bisphenol F (BPF) S (BPS). However, due structural similarity BPF BPS BPA, questions arise about safety their usage. toxicity BPF, towards humans animals been fairly well understood. biodegradability potential microorganisms each these bisphenols is widely recognized. scale inhibitory pressure on microbiomes enzyme activity not estimated. These parameters are extremely important determining health, which turn influences plant growth development. Therefore, manuscript, knowledge expanded systematized regarding differences between its two analogs. In context synthetic characterization effects permeation into environment, impact microbiological biochemical soils was traced. response cultivated plants influence analyzed.

Maize (Zea mays L.) Plants Alter the Fate and Accumulate Nonextractable Residues of Sulfamethoxazole in Farmland Soil

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(21), P. 9292 - 9302

Published: May 16, 2024

The fate of sulfonamide antibiotics in farmlands is crucial for food and ecological safety, yet it remains unclear. We used [phenyl-U-14C]-labeled sulfamethoxazole (14C-SMX) to quantitatively investigate the SMX a soil–maize system 60 days, based on six-pool model. Formation nonextractable residues (NERs) was predominant unplanted soil, accompanied by minor mineralization. Notably, maize plants significantly increased dissipation (kinetic constant kd = 0.30 day–1 vs 0.17 day–1), while substantially reducing NER formation (92% 58% initially applied SMX) accumulating (40%, mostly bound roots). Significant NERs (maximal 29–42%) were formed via physicochemical entrapment (determined using silylation), which could partially be released taken up plants. consisted considerable amount (1–8%) alkali-hydrolyzable covalent bonds (2–12%, possibly amide linkage). Six 10 transformation products quantified soil extracts NERs, respectively, including hydroxyl substitution, deamination, N-acylation, among N-lactylated found first time. Our findings reveal composition instability SMX-derived soil–plant underscore need study long-term impacts reversible NERs.
