| 中文摘要 |
| 采用氢化物发生-电热石英管-原子吸收光度法对土壤、海水、海洋生物及人尿样中不同形态的砷进行了广泛的分析测定.结论指出,土壤中砷以无机砷为主,而无机砷中又以As(V)为主;海水和人尿中以有机胂为主;海洋生物体中也主要以有机胂形态存在. |
| 英文摘要 |
| Different arsenic species in soils,sea waters, marine organisms and urine are determined by using the hydride generation-electrothermal quartz furnace-atomic absorption spectrometry.The results indicates that the inorganic arsenic is a major part of arsenic in soils and As(V) is major part of inorganic arsenic.Methylated arsenic species is important in sea waters and urine.Moreover MMAA and DMAA are significant fractions in marine organisms. |
