Adsorption of Estradiol by Natural Clays and Daphnia magna as Biological Filter in an Aqueous Mixture with Emerging Contaminants

چکیده
Among emerging pollutants, endocrine disruptors such as estradiol are of most concern. Conventional water treatment technologies not capable removing this compound from water. This study aims to assess a method that combines physicochemical and biological strategies eliminate even when there other compounds present in the matrix. Na-montmorillonite, Ca-montmorillonite zeolite were used remove medium with sulfamethoxazole, triclosan, nicotine using Plackett–Burman experimental design; each was followed by filtration Daphnia magna. Results showed between 40 92% adsorption clays; no mixture adsorbed. The significant factors for presence triclosan which favored adsorption, use Ca-montmorillonite, Zeolite, time did favor estradiol. After treatment, magna able 0–93% remaining combination optimal conditions allowed removal 98% initial concentration.

Biological uptake and depuration of carbon nanotubes by Daphnia magna.
It is inevitable that carbon nanotubes (CNTs) will be released to and widely dispersed in environmental ecosystems, given their numerous expected applications. Determination of their potential for bioaccumulation by ecological receptors is thus critical. Previous, research involving several different terrestrial and benthic organisms has indicated that CNTs spiked to soils or sediments do not b...
متن کاملDaphnia magna
The cellular architecture of the Daphnia compound eye visual system was studied by using computer-aided techniques. All the neurons in one half of the bilaterally symmetric optic ganglion (OG) were reconstructed in three dimensions from serial electron micrographs. The techniques employed were those developed by Levinthal and collaborators (Macagno, Levinthal, and Sobel, Ann. Rev. Biophys. Bioe...
متن کاملBiological Surface Coating and Molting Inhibition as Mechanisms of TiO2 Nanoparticle Toxicity in Daphnia magna
The production and use of nanoparticles (NP) has steadily increased within the last decade; however, knowledge about risks of NP to human health and ecosystems is still scarce. Common knowledge concerning NP effects on freshwater organisms is largely limited to standard short-term (≤48 h) toxicity tests, which lack both NP fate characterization and an understanding of the mechanisms underlying ...
متن کاملDaphnia as an Emerging Epigenetic Model Organism
Daphnia offer a variety of benefits for the study of epigenetics. Daphnia's parthenogenetic life cycle allows the study of epigenetic effects in the absence of confounding genetic differences. Sex determination and sexual reproduction are epigenetically determined as are several other well-studied alternate phenotypes that arise in response to environmental stressors. Additionally, there is a l...
متن کاملHazard assessment for a pharmaceutical mixture detected in the upper Tennessee River using Daphnia magna
Widespread use of pharmaceuticals has resulted in mixture concentrations ranging from mg/L in effluent to µg/L concentrations in surface water. In a 2008 study, 13 pharmaceuticals, ranging in amounts from 0.0028 to 0.1757 µg/l, were identified in the Tennessee River, USA and its tributaries. In order to address the need for risk assessment of environmentally relevant pharmaceutical mixtures, <e...
