Oxidative toxicity mediated oophoritis alters ovarian growth in Channa punctatus under prolonged exposure to herbicide, paraquat dichloride

open access: yesScientific Reports
Herbicide paraquat dichloride, a potent redox agent found its way to natural water bodies and influences their health; however, its impact on the reproductive health of fish is potentially less studied and requires clear investigation.

Integrated Evaluation of Contaminant Profiles, Detection Techniques, and Management Strategies for Tannery Sludge

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This review article critically examines the environmental and health hazards of tannery sludge (TS), a complex by‐product of the leather tanning industry. TS is characterized by a diverse array of contaminants, including heavy metals like chromium, organic pollutants such as polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds ...

Mechanism of Hydrogen Sulfide Generation and Prevention Strategies in Oil and Gas Fields: A Case Study of the Sickle Bay Operation Area

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To address the persistent exceedance of hydrogen sulfide (H2S) concentrations and the limited effectiveness of existing treatments in the Sickle Bay oil production area, this study deeply analyzes the mechanism of H2S generation in the Sickle Bay oil production area and proposes targeted prevention and control strategies. The results show that

Oxidative stress, inflammation, and steatosis elucidate the complex dynamics of HgCl2 induced liver damage in Channa punctata

open access: yesScientific Reports
Water bodies are highly pollution-prone areas in which mercury (Hg) is considered as a major menace to aquatic organisms. However, the information about the toxicity of mercuric chloride (HgCl2) in a vital organ such as the liver of fish is still ...

High temperature induces reproductive dysfunction in male zebrafish via DNA methylation-mediated tssk6 downregulation

open access: yesEcotoxicology and Environmental Safety
High temperature (HT) poses a significant threat to aquatic organisms, yet the molecular mechanisms underlying HT-induced reproductive impairment in fish remain unclear. In this study, we demonstrated that both short-term (< 21 days) and long-term (> 120

Spatial distribution, sources, and risk assessment of potentially toxic elements in cultivated soils using isotopic tracing techniques and Monte Carlo simulation

open access: yesEcotoxicology and Environmental Safety, 2023
Potentially toxic elements (PTEs) in cultivated lands pose serious threats to the environment and human health. Therefore, improving the understanding of their distinct sources and environmental risks by integrating various methods is necessary.

Soybean Adaptation Mechanisms to Drought Through Stomatal Regulation, Carbon Assimilation, and Water Use Efficiency in Sustainable Farming Systems

open access: yesAGRIVITA Journal of Agricultural Science
Unlike other crops, soybeans can be produced for both direct human consumption and industrial use. However, soybean production is highly sensitive to drought. This is because drought conditions can reduce photosynthesis and crop yield.
