The current study investigates the concentration of eleven trace elements in biomaterials including hair (85) and nails (85) along with seventy five (75) road dust samples collected from a healthy population of habitable urban-industrial areas of Hefei, China. The samples were acid digested and analyzed using ICPMS for trace elements content. The mean concentration of Elements followed descending order of Zn > Mg > Fe > Cr > Al > Sn > Sr > Ti > Cu > As > Cd and Mg > Zn > Fe > Cr > Al > Sn > Ti > Cu > Sr > As > Cd in hair and nails, respectively. Overall, the concentration of elements was found to be high in female subject as compared to male. The concentration of trace elements in hair and nail exceeded the maximum permissible limits in most cases. The corresponding mean values from dust samples were fairly high as compared to background values of trace elements. Middle age groups (21-30 years and 31-40 years) were observed to be the most vulnerable there-by posing a high health risk, as the concentration of trace elements was significantly high in these groups except for Al, which was detected high in age < 20 in case of both male and female. A significantly high correlation was found between trace elements in biomaterials and those detected in dust samples. In hair samples, a significantly positive correlation was noticed for As with Mg, Zn, Sn and Fe, Sn/Mg and Mg/Ti. In the case of nails, a significant correlation was observed for elements like Al, Mg, Zn, Cr, and Cu. The Cluster and principal component analysis revealed industrial and vehicular emissions as main sources for trace elements exposure in humans. (C) 2018 Elsevier Ltd. All rights reserved.

Comparison of satellite-derived LAI and precipitation anomalies over Brazil with a thermal infrared-based Evaporative Stress Index for 2003-2013 Anderson, Martha C.; Zolin, Cornelio A.; Hain, Christopher R.; Semmens, Kathryn; Yılmaz, Mustafa Tuğrul; Gao, Feng (2015-07-01) Shortwave vegetation index (VI) and leaf area index (LAI) remote sensing products yield inconsistent depictions of biophysical response to drought and pluvial events that have occurred in Brazil over the past decade. Conflicting reports of severity of drought impacts on vegetation health and functioning have been attributed to cloud and aerosol contamination of shortwave reflectance composites, particularly over the rainforested regions of the Amazon basin which are subject to prolonged periods of cloud cov...
In situ synthesis of micro-plastics embedded sewage-sludge co-pyrolyzed biochar: Implications for the remediation of Cr and Pb availability and enzymatic activities from the contaminated soil Mujtaba Munir, Mehr Ahmed; Yousaf, Balal; Ali, Muhammad Ubaid; Dan, Chen; Abbas, Qumber; Arif, Muhammad; Yang, Xiaoe (2021-06-15) Careful designing of biochar (BC) employing biological and industrial waste materials has gained much attention to improve soil health via reducing the bioavailability of heavy metals (HMs) in the contaminated-soil. Herein, a forty-day pot experiment was conducted to explore the influence of micro-plastic (MP) embedded sewage-sludge (SS). The effects of SS and MP dosage ratios (0–15%) on the physicochemical properties of the modified-biochars were also studied with slow-pyrolyzed (SBC-500 °C) and flash-pyro...
Evaluation of a compacted bentonite/sand seal for underground waste repository isolation Akgün, Haluk; AKTÜRK, ÖZGÜR (Springer Science and Business Media LLC, 2006-06-01) This study investigates the performance of an optimum compacted bentonite/sand mixture seal for the isolation of underground waste repositories. Engineering geological tests such as compaction, flow, swelling, mechanical and shear strength tests have been conducted to select an optimum mixture and to recommend a stable bentonite/sand seal length-to-radius ratio (L/a) as far as the factor of safety (F) is concerned. The results of the compaction permeameter tests led to a recommendation to select an optimum ...
Assessment of trace metal pollution in the coastal sediments of Fethiye-Go spacing diaeresis cek Bay (SW Turkey) and evaluation of pollution sources Gulsen-Rothmund, Halil Ibrahim; ARSLAN, ŞEBNEM; Kurtulus, Bedri; Tunca, Evren; Avşar, Ulaş; Avsar, Ozgur (2023-01-01) This research evaluated the trace metal pollution and the pollution sources in the coastal sediments of Fethiye-Go center dot cek Bay by using the spatial distribution maps, correlation and statistical analysis, which were acquired from 69 sampling points. Spatial distribution maps for eleven elements (namely Al, As, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Ti, V, and Zn) revealed that there is an enrichment of the studied elements, especially near Fethiye harbor. Moreover, the contamination evaluation carried out b...
Radon concentration in hot springs of the touristic city of Sarein and methods to reduce radon in water Jalili-Majareshin, A.; Behtash, A.; Rezaei-Ochbelagh, D. (2012-07-01) The aim of this research was to measure the efficiency of various simple methods to decrease the concentration of radon in hot springs of the touristic city of Sarein (a touristic city in northwest Iran). With the aid of "RAD7" radon detector, concentrations in water varied from 212 Bq m(-3) to 3890 Bq m(-3). Using 250 mL. vials half-filled with water samples, our research showed that when the temperature of the water increased from 17 degrees C to 27 degrees C, the radon concentration decreased from 3230 B...
