Are New Phthalate Ester Substitutes Safer than Traditional DBP and DiBP? Comparative Endocrine-Disrupting Analyses on Zebrafish Using In Vivo, Transcriptome, and In Silico Approaches

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(37), P. 13744 - 13756

Published: Sept. 7, 2023

Although previous studies have confirmed the association between phthalate esters (PAEs) exposure and endocrine disorders in humans, few to date systematically assessed threats of new PAE alternatives disruptions. Herein, zebrafish embryos were continuously exposed two PAEs [di-n-butyl (DBP) diisobutyl (DiBP)], structurally related [diiononyl (DINP) diisononyl hexahydrophthalate (DINCH)], non-PAE substitutes [dipropylene glycol dibenzoate (DGD) glyceryl triacetate (GTA)], endocrine-disrupting effects investigated during early stages (8–48 hpf). For five endogenous hormones, including progesterone, testosterone, 17β-estradiol, triiodothyronine (T3), cortisol, tested chemicals disturbed contents at least one hormone environmentally relevant concentrations (≤3.9 μM), except DINCH GTA. Then, concentration-dependent reduced transcriptome analysis was performed. Thyroid (TH)- androgen/estrogen-regulated adverse outcome pathways (AOPs) types biological most sensitive exposure. Notably, six compounds disrupted four TH-mediated AOPs, from inhibition deiodinases (molecular initiating event, MIE), a decrease T3 levels (key KE), mortality (adverse outcome, AO) with quantitatively linear relationships MIE-KE (|r| = 0.96, p 0.002), KE-AO 0.88, 0.02), MIE-AO 0.89, 0.02). Multiple structural analyses showed that benzoic acid is critical toxicogenic fragment. Our data will facilitate screening development green alternatives.

Exfoliation and physico-chemical characterization of novel bioplasticizers from Nelumbo nucifera leaf for biofilm application

Heliyon, Journal Year: 2023, Volume and Issue: 9(12), P. e22550 - e22550

Published: Nov. 20, 2023

Due to the extreme threats as environmental and health issues caused by petroleum-based leachable plasticizers, researchers among different domains are more interested in finding unique biodegradable plasticizers from natural sources. The present study used Nelumbo nucifera leaf extract novel biopolymers viable substitutes for chemical plasticizers. extraction was carried out through means its physico-chemical morphological characterization were confirm plastic nature. polymers extracted possess a low glass transition temperature (77.17 °C), good thermal stability (230 density (0.94 g/cc), surface roughness (34.154 μm), crystallinity index (25.1%) moderate crystallite size (16.36 nm). presence of an organic polymer with specific groups olefinic alkenes, epoxide, imino/azo groups, hydrophobic siloxane signify that material is condensed phenolic derivative. Furthermore, bio-film formulated using NLP poly lactic acid (PLA) matrix evaluate plasticizing effect film-forming ability. Variation properties film noted after bio-plasticizer addition, where tensile strength (20.94 ± 1.5 MPa 19.22 1.3 MPa) Young's modulus (1.462 0.43 GPa 1.025 0.52 GPa) found be decreased whereas increased percentage elongation at break (26.30 1.1% 39.64 1.6%). In (Tg) (59.17 compatibility, flexibility NLP-PLA contrast pure PLA authorizes bio-plasticizers on PLA. Since could suitable replacement harmful synthetic lightweight packaging applications bioplastics sector.

ICE-SSD Model: Bridging the Ecological Risk Assessment Gap between Plasticizer and the Substitute

ACS ES&T Water, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 6, 2025

The eco-safety of plasticizer alternative di-isobutyl phthalate (DiBP) has received continued concerns owing to its large usage as a and high detection frequency in environments. concentrations dibutyl (DBP) DiBP the surface waters ranged from ng/L μg/L. However, accurate ecological risk assessment alternatives is limited by data on toxic effects potencies. interspecies correlation estimation (ICE) model combined with species sensitivity distribution (SSD) was used assess DBP DiBP. acute reproductive predicted no-effect (PNECs) were derived 0.05 mg/L 1.23 μg/L for 0.16 0.51 based ICE-SSD models. Our results showed that risks (risk quotient (RQ) < 0.1) mainland China waterbodies, except Hangzhou Bay, acceptable. quotients indicated Yangtze River (RQ = 1.55 0.48), Hun 1.74 6.03), Bay 7.33 13.49) had relatively levels PNECs Furthermore, joint probability curves needed further concern. Thus, could effectively compensate lack toxicity assessment.
