摘要

2017年10月至2018年7月,对伊兹密尔湾两种大型藻类(Cystoseira crinita和Halopteris scoparia)和海草(Cymodocea nodosa)作为痕量金属和210Po生物监测物的生物利用度进行了评估。采用能量色散x射线荧光光谱法测定样品中Al、Fe、Zn、Mn和Pb的含量。用α光谱法测定了210 - po的活性浓度,结果表明,冬冬冬冬藤积累的210 - po浓度最高。此外,大型藻类(c.c reinita和H. scoparia)在同一区域也有不同水平的210Po积累。另外,调查测定微量金属在h . scoparia和c nodosa在冬天。在研究中观察到微量金属和210Po浓度的季节性波动。

Trace Metals and 210Po Activity Concentrations in Macroalgae (Cystoseira Crinita and Halopteris Scoparia) and Seagrass (Cymodocea Nodosa) in Izmir Bay, Aegean Turkish Coast
Two types of macroalgae (Cystoseira crinita and Halopteris scoparia) and seagrass (Cymodocea nodosa) have been evaluated for their bioavailability as biomonitors of trace metals and 210Po in Izmir Bay during the period of October 2017-July 2018. The levels of Al, Fe, Zn, Mn and Pb in the samples were determined using energy dispersive x-ray fluorescence spectrometry. The activity concentrations of 210Po were measured by alpha spectrometry and the results have shown that C. nodosa were found to accumulate the maximum 210Po concentration in the winter. Besides, macroalgae (C.crinita and H. scoparia) were also found to accumulate 210Po at different levels in the same area. Additionaly, the investigated trace metals were determined in H. scoparia and C. nodosa in the winter. A seasonal fluctuations in trace metals and 210Po concentrations were observed in the study.
