The Distribution of Microphytoplankton and Heavy Metal Content of Xiangshan Bay in Spring

Abstract:

The abundance of microphytoplankton and distribution of soluble heavy metal content of Xiangshan Bay were investigated in 2012. And the results showed that the abundance of microphytoplankton was 22×10⁴~502×10⁴ cells/m³ and the average cell abundance was 117×10⁴ cells/m³. The dominant species of microplankton were Coscinodiscus jonesianus. The abundance of microplankton cells reduced from middle port to the mouth of the port. The concentrations of Hg, As, Cu, Pb, Zn, Cd and total Cr of surface seawater in the whole areas studied were satisfied the class I water standard. Due to human activities, the concentrations of some areas in the bottom and middle of the port were relatively high and approximately satisfied class II water standard. The concentrations reduced from bottom to the mouth, however, most sea areas were still satisfied class I water standard
