A closed-system algal toxicity test with no headspace was applied to evaluate the toxicity of 11 aldehydes and two nitriles to Raphidocelis subcapitata. Algal growth rate and dissolved oxygen (DO) production were used as the test endpoints. Compared to literature data, our test results based on the endpoint of DO production is 2.5 to 257 times more sensitive than the conventional algal batch te...
Degradation products formed during removal of an aqueous nonylphenol ethoxylate compound (NP-10) by the H2O2/UV-C, Fenton (Fe/H2O2) and photo-Fenton (Fe/H2O2/UV) advanced oxidation processes and their relationship with the acute toxicity toward Vibrio fischeri photobacteria were investigated. Polyethylene glycols with 3-8 ethoxy units, aldehydes and carboxylic acids were identified as the prima...
The effects of nanoparticle (NP) properties, such as size, shape and surface charge, on their efficacy and toxicity have been studied extensively. However, the effect of controlled drug release on NP efficacy and toxicity has not been thoroughly evaluated in vivo. Our study aims to fill this knowledge gap. A key challenge in characterizing the relationship between drug release and therapeutic r...
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
the toxicity of 7 herbicides to the three cyanobacteria was tested in this work. the results indicated that: (1) there was a highly significant relationship between dried weight or chlorophyll-a and od680nm for tested cyanobacteria; (2) the toxicity of the tested herbicides with the order from high to low was: photosynthesis-inhibiting > accase inhibitor > protox inhibiting herbicides; (3) the ...
