Acute toxicity of titanium dioxide nanoparticles in Daphnia magna and Pontogammarus maeoticus
Titanium dioxide nanoparticles (nTiO2) are the world's second most widely consumed nanomaterial and large quantities of this material enters the aquatic ecosystem annually. Therefore, understanding the effects of nTiO2 on aquatic organisms is very important. The present study used Daphnia magna as a model freshwater organism and Pontogammarus maeoticus as a brackish water organism to evaluate s...
متن کاملCalcium interacts with temperature to influence Daphnia movement rates
Predicting the ecological responses to climate change is particularly challenging, because organisms might be affected simultaneously by the synergistic effects of multiple environmental stressors. Global warming is often accompanied by declining calcium concentration in many freshwater ecosystems. Although there is growing evidence that these changes in water chemistry and thermal conditions c...
متن کاملFreshwater ciliates as ecophysiological model organisms – lessons from Daphnia, major achievements, and future perspectives
Similar to Daphnia, many planktonic ciliates are algivores that occur in virtually every natural lake and reproduce primarily asexually. Due to their larger population size and shorter generation time, their significance as algal consumers and secondary producers may exceed that of Daphnia during algal blooms and when averaged over the season. The high reproduction rate, the ease of culturing, ...
متن کاملSurvey of indicator toxicity of Isfahan south of wastewater treatment plant by using of daphnia magna
Introduction: Bioassay is necessary for assessment of pollution. Because physical and chemical taste are not enough for assessment of potential effects on water ecosystem. Bioassay tests have alot of scientific value inanition doing of them is easy and need less time, also need less space, laboratory equipment’s and expenditure. Therefor such tests have found special attention in water pollutio...
متن کاملImproving Photobioreactor wall Using Optical Brightener: Investigating the Photostability of Coated Layer and Algal Growth
In this work, photostability, absorption and emission intensity of coated polycarbonate (PC) sheets with optical brightener (OB) as a wavelength converter material have been investigated. In addition, this coated sheet was used as a wall for microalgae culture flask, as a small scale photobioreactor, for studying the spectral conversion of UV-A radiation to blue light region and its effect ...
