In the natural environment, interactions of different types nanoparticles (NPs) may alter their toxicity, thus masking true environmental effects. This study investigated toxicity silver NPs (AgNPs) combined with hematite (HemNPs) or polystyrene (PsNPs) toward freshwater algae Chlamydomonas reinhardtii and Ochromonas danica. The former has a cell wall cannot internalize these NPs, while latter without can. Therefore, AgNPs C. was attributed to released Ag ions, had direct toxic effects on O....
Abstract The thermal decomposition of Nafion N117 membrane, a typical perfluorosulfonic acid membrane that is widely used in various chemical technologies, was investigated this study. Structural identification thermolysis products water and methanol performed using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC/ESI-MS/MS). fluoride release studied an ion-chromatography system the stability characterized by thermogravimetric analysis. Notably, several types...
When nanoparticles can enter a unicellular organism directly, how may they affect the bioaccumulation and toxicity of other pollutants already present in environment? To answer this question, we conducted experiments with protozoan Tetrahymena thermophila. The well-dispersed polyacrylate-coated TiO2 (PAA-TiO2–NPs) were used as representative nanomaterial, Cd conventional pollutant. We found that PAA-TiO2–NPs could get into cells directly. Such internalization was first induced by low...
The bioaccumulation kinetics of thioglycolic acid stabilized CdTe quantum dots (TGA-CdTe-QDs) in a freshwater alga Ochromonas danica was comprehensively investigated. Their photoluminescence (PL) determined by flow cytometry. Its cellular intensity increased hyperbolically with exposure time suggesting real internalization TGA-CdTe-QDs. This hypothesis evidenced the nanoparticle uptake experiment heat-killed or cold-treated cells and their localization vacuoles. TGA-CdTe-QD accumulation...
Potassium ferrate [Fe(VI)] is a promising oxidant widely used in water treatment for the elimination of organic pollutants. In this work, reaction kinetics, products, and mechanisms antimicrobial agent chlorophene (CP) undergoing Fe(VI) oxidation aqueous solutions were investigated. CP very readily degraded by Fe(VI), with apparent second-order rate constant, k, being 423.2 M–1 s–1 at pH 8.0. A total 22 products identified using liquid chromatography–quadrupole time-of-flight–mass...
Calcium plays versatile roles in aquatic ecosystems. In this study, we investigated its effects on the uptake of polyacrylate-coated TiO2 nanoparticles (PAA-TiO2-NPs) by water flea (cladoceran) Daphnia magna. Particle distribution these daphnids was also visualized using synchrotron radiation-based micro X-ray fluorescence spectroscopy, transmission electron microscopy, and scanning microscopy. At low ambient Ca concentrations experimental medium ([Ca]dis), PAA-TiO2-NPs were well dispersed...
