Interspecific Differences in the Effects on Embryos Between Freshwater and Marine Fish Exposed to Water‐Accommodated Fractions Derived From Very‐Low Sulfur Fuel Oil

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the toxic effects of water‐accommodated fractions (WAFs) of very‐low sulfur fuel oil (VLSFO) on freshwater and marine fish embryos. Embryos of Japanese medaka (Oryzias latipes), Java medaka (Oryzias javanicus), and grass puffer (Takifugu alboplumbeus) were exposed to various concentrations of VLSFO‐WAF, and the effects on ...

Potential of Salicylic Acid and Synthetic Surfactant on Anthracene and Fluoranthene Remediation by Impatiens balsamina

Walailak Journal of Science and Technology, 2019
Plant growth regulators and synthetic surfactants are alternative choices for enhancing the efficiency of PAH phytoremediation. In this study, the use of salicylic acid alone, surfactant alone (Triton X-100 or Tween 80) or salicylic acid together with ...

Wildfire Ash Alters Freshwater Crustacean Behavior: Disentangling the Contributions of Suspended Macroparticles and Ash‐Induced Alkalinization

Environmental Toxicology, EarlyView.
ABSTRACT Climate change and anthropogenic ignitions are intensifying wildfire frequency worldwide, elevating the risk of freshwater contamination by ash. In water, dissolved ash releases ions and other toxic constituents that increase pH and alter physicochemical conditions, while suspended ash particles may impose mechanical stress, disrupt behavior ...

Volatile Organic Compounds in Rainwater: A New Frontier in Atmosphere–Biosphere Interactions

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Rainwater is a key vector of atmospheric deposition, linking the atmosphere with terrestrial and aquatic ecosystems. While the inorganic chemistry of precipitation (dominated by sulfate, nitrate, ammonium, and trace metals) has been extensively studied, organic compounds in rainwater have received less attention, and Volatile Organic Compounds
