Resolving the distribution and speciation of metal(loid)s within biological environmental samples is essential for understanding bioavailability, trophic transfer, and environmental risk. We used synchrotron x-ray microspectroscopy to analyze a range of samples that had been exposed to metal(loid) contamination. Microprobe x-ray fluorescence elemental mapping (mSXRF) of decomposing rhizosphere ...

Durability of concrete structure in marine environments is a big issue for many decades due to chloride attack. Chloride penetrates the concrete structure and accelerates the corrosion process of reinforcement which decreases the life of those structures. Also shrinkage cracks in concrete play main role for chloride penetration through concrete surface.  Many researchers tried to find easy and ...

Selenium pollution from coal ash wastewater was investigated in Lake Sutton, NC. This lake has been continuously used as a cooling pond for a coal-fired power plant since 1972. Historic and recent levels of contamination in fish tissues (14-105µg Se/g dry weight in liver, 24-127 in eggs, 4-23 in muscle, 7-38 in whole-body) exceeded toxic thresholds and teratogenic effects were observed in fish ...

Periphyton development and composition were studied in three different treatments: (i) two fishpond units of wetland-type wastewater treatment pond systems, (ii) two fishponds in combined intensive-extensive fish farming systems and (iii) three traditional polyculture fishponds. Results showed that amounts of periphyton developed in traditional polyculture fishponds (iii) were different compare...
