我们于1980年8月—1981年5月分析测定了渤海海区30个站位(图1)三个不同季节的样品,其中包括121份表层、底层水样和30个站位海底沉积物以及39份生物样品(共计190份样品)中~(137)Cs含量的测定。~(137)Cs测定方法按“海洋污染调查暂行规范”中的磷钼酸铵—碘铋酸铯—β计数法进行,研究分析了渤海~(137)Cs含量的分布状况,探讨了一些环境因素,如地理位置、水深、季节、盐度等对渤海环境中~(137)Cs含量分布的影响。
In August 1980-May 1981, we analyzed and measured three samples from 30 stations in the Bohai Sea (Figure 1) in different seasons, including 121 surface and bottom water samples and 30 stations of seafloor sediments and 39 Determination of ~ (137) Cs in Parts of Biological Samples (Total of 190 Samples). The determination of ~ (137) Cs was carried out in accordance with the Cesium-β counting method of ammonium phosphomolybdate-iodine-bismuth in the Interim Provisions for the Investigation of Marine Pollution, and the distribution of ~ (137) Cs in Bohai Sea was studied and analyzed. Factors, such as geographical location, depth, season, salinity and other factors on the distribution of 137Cs in the Bohai Sea.
