Insights into the Effects of Hydroxycinnamic Acid and Its Secondary Metabolites as Antioxidants for Oxidative Stress and Plant Growth under Environmental Stresses

Current Issues in Molecular Biology, Год журнала: 2023, Номер 46(1), С. 81 - 95

Опубликована: Дек. 21, 2023

Plant immobility renders plants constantly susceptible to various abiotic and biotic stresses. Abiotic stresses are known produce reactive oxygen species (ROS), which cause comparable cellular secondary reactions (osmotic or oxidative stress), leading agricultural productivity constraints worldwide. To mitigate the challenges caused by these stresses, have evolved a variety of adaptive strategies. Phenolic acids form key component strategies, as they predominantly be secreted in response can divided into different subclasses based on their chemical structures, such hydroxybenzoic hydroxycinnamic acids. This review analyzes derivatives increase under stressful conditions, so withstand environmental regulate physiological processes through acting signaling molecules that gene expression biochemical pathways. The mechanism action used acid involves minimization damage maintain homeostasis protect vital components from harm. purpose this is highlight potential metabolites/derivatives antioxidants. We uses metabolites associated with contributions plant growth development.

Trace element of small lake sediments sensitively recorded environmental changes in the watershed: Implications for mining history and urbanization

Ecological Indicators, Год журнала: 2023, Номер 158, С. 111422 - 111422

Опубликована: Дек. 20, 2023

Lake sediments serve as a sink for trace elements and provide record of watershed changes resulting from anthropogenic activities natural processes. In this study, eight in the Aha, an urban lake Guiyang City, Southwest China, were investigated to reveal effects historical coal mining rapid urbanization watershed. Results showed that median contents measured order Zn (220.00 mg/kg) > Ni (98.16 Cr (70.26 Cu (66.20 As (58.14 Co (41.66 Pb (28.33 Cd (1.39 mg/kg). Except Pb, concentrations Cd, As, Zn, Ni, Co, 4.64, 2.33, 2.00, 1.92, 1.81, 1.09 times higher than regional background values respectively. Trace element center significantly rest sediment cores, relatively stable hydrodynamic processes region. Vertical variation indicated fluctuations intensity tributaries effectively tracked by variations levels middle layer Youyu River Baiyan estuaries. The elevated surface Jinzhong estuary reflected basin over past 20 years. PMF analysis demonstrated mixture activities, Cu, originated mining. This study provides important information comprehending small-scale lakes environmental changes.

Novel Materials for Heavy Metal Removal in Capacitive Deionization

Applied Sciences, Год журнала: 2023, Номер 13(9), С. 5635 - 5635

Опубликована: Май 3, 2023

Heavy metals are considered a class of contaminant that can accumulate in the food chain and thus must be removed from contaminated media. by electrocoagulation, electroflotation, electrodialysis, capacitive deionization, so on. Among methods to remove heavy metals, deionization is one most attractive metal ions without using large volume chemicals producing high number containing solid wastes. In this study, after brief introduction mechanism we focus on materials have been developed as electrodes for removal summarize latest advancements. Finally, with particular emphasis material design, provide some further insights area.

Assessment of heavy metal pollution in sediments from the urban section of Yihe River, Linyi City, China

PLoS ONE, Год журнала: 2025, Номер 20(2), С. e0318579 - e0318579

Опубликована: Фев. 13, 2025

The Yihe River is the largest mountain torrent river in Shandong Province, which plays an important role flood control, irrigation and climate regulation. Due to impacts of upstream urban domestic sewage, as well industrial agricultural wastewater, Linyi City section expected have a high risk metal pollution. Sediments are main reservoir potential release source metals (metalloid) systems. Assessment sediments can identify anthropogenic In this study, 25 sediment samples were collected from its tributaries, concentration As, Cd, Cr, Cu, Ni, Pb Zn quantified by inductively coupled plasma mass spectrometry (ICP-MS), Hg was determined atomic fluorescence (AFS). pollution levels evaluated determining contamination factor, load index, geoaccumulation ecological assessment toxicity index. Correlation analysis absolute principal component-multiple linear regression (APCS-MLR) used conduct apportionment. Pb, Zn, detected all samples. Overall, stream mostly within environmental background value, overall state no slightly polluted, while tributaries polluted state. Cd two pollutants surface study area, with average content 1.65 1.11 times respectively. Most areas free pollution, low risk. risks (Suhe River, Benghe Liuqinghe River) center island (Yihe North Island) assessed presenting toxicity. Source showed that As mainly come natural sources activities, result transportation industry. results help us understand distribution sediments, also provide management support local departments relevant national departments.
