摘要
为了研究海藻体内元素的变迁在监测海洋环境污染状况方面的应用 ,作者利用同步辐射 X射线荧光 ,对分别在 1985年 7月和 1999年 7月采自中国山东省青岛海滨的浒苔 (Enteroinorpha prolifera)、海蒿子 (Sargassumpallidum)和鸭毛藻 (Symphyocladia latiuscula)进行了元素的分析。研究结果表明 ,各种不同的海藻 ,各自有相当稳定的 XRF谱型。同 1985年样品的 XRF谱相比 ,在 1999年的所有样品中 ,许多元素的峰强都明显增高了。 Br的含量在鸭毛藻中最高 ,海蒿子次之 ,浒苔最少。同 1985年相比 ,1999年的鸭毛藻中 Br的含量几乎无变化 ,可能在 1985年就已接近饱和。
In order to study the changes of elements for the purpose of monitoring the oceanic contamination in marine algae,we have analyzed Enteroinorpha prolifera,Symphyocladia latiuscula and Sargassum pallidum for elements,which were collected from the seaside of Qingdao of Shandong Province in China separately in July 1985 and July 1999,with X-ray fluorescence of synchrotron radiation.The result expresses that there is a quite stable type of XRF spectra respectively,among different species of marine algae.In comparison with the specimens of 1985,the peak value of XRF about many elements,had risen in all ones of 1999.S.latiuscula is the highest in the concentration of Br,S.pallidum is second,E.prolifera is the lowest.In comparison with 1985,Br with S.latiuscula hardly change in 1999,and it had been already saturated for absorbing Br in 1985.
