| titleOfInvention | A device for measuring the flux of heavy metals in atmospheric deposition using sediment |
| abstract | The present invention proposes a device for measuring the flux of heavy metals in atmospheric deposition by using sediment, comprising: a seawater storage device, a water pump and several sedimentary columns arranged in a line, the seawater storage device is used for placing seawater, and the sedimentary column It is placed vertically, the upper end of the deposition column is open, the lower end of the deposition column is connected with a detachable bottom cover for sealing, and the deposition column is sequentially provided with sedimentary phase, seawater phase and air phase from bottom to top. The seawater phases of the columns are connected in sequence, and the sedimentation column arranged at the first position and the sedimentation column at the last position are both communicated with the seawater storage device, and the water pump drives the water flow to circulate. The invention can effectively eliminate the background value of heavy metals, the changes of deposition types and the disturbance of human activities, so that the measurement results can directly reflect the heavy metals stored in the sediments from atmospheric deposition every month. |
