摘　　要：应用氢化物发生-原子荧光光谱方法（HC-AFS）研究了舟山岛海域沉积物和生物样中砷的质量分数并进行了评价．结果如下：1．建立方法的线性方程为：If（As）=6．1669C-1．0649，方法的检出限为0．2ng／mL，该法测定两种标准样品的偏差分别为-6．6％和0．2％．2．沉积物和生物体中均检测到一定量的砷，沉积物中砷质量分数为：12．33～16．49μg／g，生物样中质量分数为：1．31～17．25μg／g．参考海洋沉积物和生物质量标准，前者属于一类沉积物，后者属于二类海洋生物；参考FAO／WHO建议的每日摄入总量，适当食用此类海洋生物是安全的．The study of arsenic was taken up to determined and to evaluate sediments and organisms from zhoushan Island by atomic fluorescence spectrometry. The results were that： 1. The method is accuracy, linear equation ：If （As）=6. 166 9 C-1. 064 9,detection limit：0. 2 ng/mL, differences with two certificated reference materials were -6.6% and 0.2%. 2. Arsenic was determined in sediments and organisms, the detected arsenic range in sediments was 12.33-16.49 μg/g, in organisms was 1.31-17.25 μg/g. Referring to marine sediment quality and marine bi- ological quality, sediments belongs to the first species marine sediment, organisms belongs to the second species ma- rine biological organism. Refer to daily gross advised by FAO/WHO,it is safe to take moderate oceanic organisms.
