摘要：In order to study the possibility of using shellfish shell as a carrier for monitoring and recording heavy metal pollution of rivers, Unio Dou Glasiae samples from five rivers were collected, including the Harbin river section of the upper reaches of Songhua River, the Zhaoyuan river section, the Songyuan river section, the Qigihar river section of the Nenjiang upstream of the Songhua River upstream, and the Da an river section. Twelve metal elements including aluminum (Al), chromium (Cr), iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), selenium (Se), cadmium (Cd), and lead were detected by the collision cell inductively coupled plasma mass spectrometry (ICP-MS), the test results showed the shell of Unio Dou Glasiae enriched a large amount of metal elements. Seven elements of aluminum (Al), chromium (Cr), iron (Fe), manganese (Mn), cobalt (Co), zinc (Zn) and arsenic (As) in water samples and shellfish samples have high content in the shell samples collected from large urban sampling points such as Harbin and Qigihar, which reflects the correlation between the enrichment range of these elements and human activities, and a comprehensive circle. The distribution of the mussel, the size of the individual and the living habits of the clam, the conclusion is that the shell of the dome is suitable for monitoring the heavy metal pollution in the water environment on Songhua River.
