Estrogens have attracted extensive attention because of their harmful effects on organisms such as endocrine disturbance and reproductive toxicity. This study investigated the spatial temporal distribution ecological risk assessment 7 targeted estrogens in surface water a seasonal freeze-thaw basin. It mainly includes three natural estrogens, estrone (E1), 17β-estradiol (E2) estriol (E3), two synthetic 17α-ethinylestradiol (EE2) diethylstilbestrol (DES), phenolic environmental bisphenol-A (BPA) nonylphenol (NP). The total estrogen concentration was 15.30-489.62 ng·L-1. BPA, NP, DES E3 were major estrogenic pollutants showed significant differences process, from high to low wet, thawing freezing seasons. Principal sources primarily originated mixed discharge livestock domestic sewage landfill leachate. Increased runoff promoted pollution into rivers, increasing during wet seasons, latter posed higher aquatic that would be breeding season. Targeted fish moderate algae crustaceans. estradiol equivalent concentrations (EEQT) all seasons exceeded safe threshold. Therefore, it is suggested strengthen monitoring frequency different adopt strict treatment measures reduce harm environment.

Pollution Characteristics and Risk Prediction of Endocrine Disruptors in Lakes of Wuhan

Toxics, Год журнала: 2022, Номер 10(2), С. 93 - 93

As a new and ubiquitous trace organic pollutant, endocrine-disrupting compounds (EDCs) can cause effects on organisms even at low levels. However, little information is available the resource assessment of EDC risks in water environment. The study area was selected based paucity pollution status inland lakes. Wuhan has numerous diverse types lakes which receive micropollutants from different pathways. In this study, spatial distribution, occurrence, quantity ecological EDCs 12 were investigated. Five EDCs, including 17-alpha-ethinylestradiol (17α-EE2), estrone (E1), β-estradiol (β-E2), estriol (E3) bisphenol A (BPA) detected surface waters. distribution content ordered as follows: exurban zone < suburban urban areas. sources remote mainly included agricultural aquaculture wastewater, while those areas domestic or industrial wastewater. Areas with higher frequently related to activities, dense populations. Water quality parameters, dissolved oxygen, pH temperature, significantly occurrence Risk demonstrated that posed minimum medium risk aquatic results showed faced threat hormone though it lower doses and, thus, should be considered future environmental policies decisions China.

Assessment of estrogenic potential from exudates of microcystin-producing and non-microcystin-producing Microcystis by metabolomics, machine learning and E-screen assay

Journal of Hazardous Materials, Год журнала: 2024, Номер 470, С. 134170 - 134170

Опубликована: Апрель 9, 2024

Cyanobacterial blooms, often dominated by Microcystis aeruginosa, are capable of producing estrogenic effects. It is important to identify specific compounds produced cyanobacteria, though this can prove challenging owing the complexity exudate mixtures. In study, we used untargeted metabolomics compare components exudates from microcystin-producing and non-microcystin-producing M. aeruginosa strains that differed with respect their ability produce microcystins, across two growth phases. We identified 416 chemicals found similar components, mainly organoheterocyclic (20.2%), organic acids derivatives (17.3%), phenylpropanoids polyketides (12.7%), benzenoids (12.0%), lipids lipid-like molecules (11.5%), oxygen (10.1%). then predicted group using random forest machine learning. Six (daidzin, biochanin A, phenylethylamine, rhein, o-Cresol, arbutin) belonging (3), (2), compound (1) were tested exhibited potency based upon E-screen assay. This study confirmed both contain properties, a growing concern in cyanobacteria management.

Bioremediation of Synthetic Wastewater with Contaminants of Emerging Concern by Nannochloropsis sp. and Lipid Production: A Circular Approach

Bioengineering, Год журнала: 2025, Номер 12(3), С. 246 - 246

Опубликована: Фев. 28, 2025

Contaminants of emerging concern (CECs) pose a potential risk to human and environmental health. Microalgae bioremediation is promising approach for transforming or removing contaminants from the environment, while contributing circular economy. In this study, Nannochloropsis sp. was effectively used simultaneous removal six CECs: paracetamol, ibuprofen, imidacloprid, methylparaben bisphenol A at 10 µg mL−1 triclosan 0.5 synthetic wastewater, which were able survive under such concentrations, higher than those commonly found in environment (up 2.82 methylparaben). High efficiencies reached (100%) (93 ± 2%), paracetamol 30 1%, 64 2% 49 5% removed, respectively. Subsequently, lipids extracted, FAME profile characterised using GS-MS. The main fatty acids identified after hexadecadienoic acid isomers (C16:2), palmitic (C16), linoleic (C18:2) γ-linolenic (C18:3). absence oleic stearic noticed, suggesting an alteration lipidic due contaminant exposure. By exploring quantification future work, applications extracted can be explored, further demonstrating feasibility process.

Microalgal consortium tolerance to bisphenol A and triclosan in wastewater and their effects on growth, biomolecule content and nutrient removal

Ecotoxicology and Environmental Safety, Год журнала: 2023, Номер 262, С. 115117 - 115117

Amongst the many treatments available for removal of emerging contaminants in wastewater, microalgal cultures have been shown to be effective. However, effectiveness exposure a native consortium such as bisphenol-A (BPA) and triclosan (TCS) determine half-maximum effective concentrations (EC50) has not yet determined. The effect on growth nutrient treatment well production biomolecules carbohydrates, lipids, proteins are, at present, unknown. In this study, EC50 BPA TCS (96-hour experiments) was determined using microalgae (Scenedesmus obliquus Desmodesmus sp.) define maximum tolerance these contaminants. synthetic wastewater (SWW) investigated terms growth, chlorophyll (Chl-a), carbohydrate, lipid, protein content, removal. Assays were performed heterotrophic conditions (12/12 light/dark cycles). EC50-96 h values 17 mg/L 325 µg/L TCS, respectively, found 72 h. For an initial inoculum ≈ 300 mg TSS/L (total suspended solids per litre), increased by 16.1% when exposed 17.78% TCS. At 500 TSS/L, 8.25% with 9.92% respectively. did limit wastewater. Moreover, they stimulate content Chl-a, proteins, enhance AVAILABILITY OF DATA AND MATERIAL: Data sharing applicable article no datasets generated or analysed during present study.
