Ionic liquids: structure–toxicity relationships, predictive toxicology, and sustainable design

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract Ionic liquids (ILs) have often been described as green alternatives to conventional solvents because of their negligible vapor pressure and highly tunable properties. However, low volatility does not necessarily translate into environmental safety, as their biological and ecological effects are strongly influenced by molecular structure.

Daphnia metacommunity dynamics : the roles of inbreeding, parasitism, competition, and dispersal [PDF]

open access: yes, 2011
The habitats of many species are not continuous but fragmented, either naturally or increasingly due to human land use. Communities of species inhabiting fragmented habitat patches are connected by dispersal and form a metacommunity, a spatial overlay of

Genotoxic Effects of Acute Difenoconazole Exposure on Daphnia magna

open access: yesÇanakkale Onsekiz Mart University Journal of Marine Sciences and Fisheries
Difenoconazole, a fungicide often used in agriculture, is harmful to aquatic organisms. However, its toxicity to aquatic organisms is not yet well recognized. Among the triazole fungicides, Difenoconazole (PEN) is one of the most extensively used in many

Oleic Acid‐Mediated Double Emulsification Enables Enhanced Aqueous Stability and Localized Photothermal Heating of Liquid Metal Droplets

open access: yesSmall Methods, EarlyView.
Oleic acid‐mediated double emulsification creates a yolk–shell‐like liquid metal photothermal platform in which the intermediate oil phase limits water transport to the liquid metal and reduces convection‐mediated heat dissipation from the irradiated region.

Acute toxicity of carbofuran to selected species of aquatic and terrestrial organisms

open access: yesPlant Protection Science, 2003
Carbofuran is an anticholinesterase carbamate commonly used as an insecticide, nematicide and acaricide in agricultural practice throughout the world. The aim of the study was to investigate the acute toxicity of carbofuran to selected species of aquatic

Influence of Age and Exposure Pathway on Copper and Cadmium Mixture Toxicity: A Study on Daphnia magna

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.
