Capillary Electrophoresis of Quantum Dots: Minireview.

Stanisavljevic M1, Vaculovicova M, Kizek R, Adam V.Author information 1Department of Chemistry and Biochemistry, Faculty of Agronomy, Mendel University in Brno, Zemedelska 1, CZ-613 00, Brno, Czech Republic, European Unio.AbstractIt has been already three decades, since the fluorescent nanocrystals called quantum dots appeared and attracted attention of a broad scientific community. Their excellent not only optical but also electronic properties predetermined quantum dots (QDs) for utilization in a variety of areas. Besides lasers, solar cells and/or computers, QDs have established themselves in the field of (bio)chemical labeling as well as medical imaging. However, due to the numerous application possibilities of QDs there are high demands on their properties which need to be precisely controlled and characterized. Capillary electrophoresis with its versatile modes and possibilities of detection was found to be an effective tool not only for characterization of QDs size and/or surface properties but also for monitoring of their interactions with other molecules of interest. In this mini-review we are giving short insight in analysis of QDs by capillary electrophoresis, and summarizing the advantages of this method for QDs characterization.

Bioaccumulation of selected metals in bivalves (Unionidae) and Phragmites australis inhabiting a municipal water reservoir.

Rzymski P1, Niedzielski P, Klimaszyk P, Poniedziałek B.Author information 1Department of Biology and Environmental Protection, Poznan University of Medical Sciences, Rokietnicka 8, 60-806, Poznań, Poland, rzymskipiotr@gmail.com.AbstractUrbanization can considerably affect water reservoirs by, inter alia, input, and accumulation of contaminants including metals. Located in the course of River Cybina, Maltański Reservoir (Western Poland) is an artificial shallow water body built for recreation and sport purposes which undergoes restoration treatment (drainage) every 4 years. In the present study, we demonstrate an accumulation of nine metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn) in water, sediment, three bivalve species (Anodonta anatina, Anodonta cygnea, Unio tumidus), and macrophyte Phragmites australis collected before complete drainage in November 2012. The mean concentrations of metals in the sediment, bivalves, and P. australis (roots and leaves) decreased in the following order: Fe > Mn > Zn > Cu > Cr > Ni > Pb > Co > Cd. A considerably higher bioconcentration of metals was observed in samples collected from the western and southern sites which undergo a higher degree of human impact. Sediments were found to be a better indicator of metal contamination than water samples. Interspecific differences in levels of metal accumulation were found between investigated unionids. U. tumidus accumulated higher levels of Cr, positively correlated with ambient concentrations, predisposing this species as a potential bioindicator of this metal in aquatic environments. On the other hand, species of Anodonta genus demonstrated higher accumulation of Cu and Cd. Positive correlations were found between Pb content in the sediments and tissues of all three bivalve species. In P. australis, metals were largely retained in roots except for Cd and Pb for which higher concentrations were found in leaves suggesting additional absorption of these metals from aerial sources. P. australis and bivalve from the Maltański Reservoir may be a potential source of toxic metals for animals feeding upon them and contribute to further contamination in the food chain.

Endocrine-disrupting effects of compounds in Danish streams.

Long M1, Strand J, Lassen P, Krüger T, Dahllöf I, Bossi R, Larsen MM, Wiberg-Larsen P, Bonefeld-Jørgensen EC.Author information 1Unit of Cellular and Molecular Toxicology, Department of Public Health, Centre for Arctic Health, Aarhus University, BartholinsAllé 2, Building 1260, 8000, Århus C, Denmark, ml@mil.au.dk.AbstractEffluents from municipal wastewater-treatment plants and scattered dwellings, as well as runoff from agricultural fields, are sources of endocrine-disrupting compounds (EDCs) in the aquatic environment. The present study investigated the correlation between the occurrence of EDCs in nine Danish streams using passive samplers (polar organic integrative samplers and silicone membranes) and determined their possible biological effects as assessed by mammal cell cultures and the mussel (Unio tumidus). The passive samplers and mussels were exposed simultaneously at the study sites. The extracts from the passive samplers were used to measure the concentrations of EDCs and the biological effects on the estrogen (ER), androgen (AR), and aryl hydrocarbon (AhR)-receptor transactivation. Male mussels were investigated for biomarkers of endocrine effects, such as the levels of vitellogenin-like proteins measured as alkali-labile phosphate (ALP). EDC concentrations, hormone-receptor transactivation (ER, AR, AhR), and level of ALP were greater downstream of wastewater-treatment plants compared with upstream sites and sites supposed to be relatively nonimpacted by wastewater. Furthermore, there was a significant positive correlation between in vitro AhR transactivation and frequency of ALP of male mussels. We conclude that wastewater effluent is an important source of endocrine-disrupting effects in the aquatic environment and that the combination of biological effect measurements and chemical analyses based on passive sampling is useful in the assessment of the ecological state of the aquatic environment.

琵琶湖周辺で食用とされているイシガイ科の二枚貝であるタテボシガイの貝殻の有効利用を目的として，金属吸着凝集材の開発を試みた。貝殻粉末の鉛，六価クロム，ヒ素に対する吸着能を調べたところ，鉛に対して特に高い吸着能を示した。鉛に対する吸着能は，ホタテガイ，マガキ及びアコヤガイの貝殻粉末でも認められた。タテボシガイ貝殻を焼成することによって表面の多孔質化とカルサイト化が認められ，鉛に対する吸着能の向上が確 …
