System and method for determining transfer of atmospheric settling heavy metals in sediments

Abstract

The invention belongs to the technical field of pollution monitoring. The invention discloses a system and a method for determining transfer of atmospheric settling heavy metals in sediments. The system for determining the transfer of atmospheric settling heavy metals in the sediments comprises a sample collection module, a deposition column preparation module, a seawater sample treatment module,an air sample treatment module, a soil sample treatment module, a first calculation module, a central control module, a bryophyte sample treatment module, a bryophyte sample analysis module, a secondcalculation module, a heavy metal transfer comparison module, a cloud storage module and a display module. According to the invention, atmospheric flow and disturbance of the external environment canbe isolated by utilizing the sediment seawater isolation method, the sediment is well protected, and a measurement result can accurately reflect a real numerical value of heavy metal from atmosphericsedimentation in the region; and the bryophyte is used as a biological monitoring indication plant, the atmospheric settlement heavy metal pollution condition is monitored by using a moss bag method,and basic data is provided for ecological environment protection.

Description

technical field [0001] The invention belongs to the technical field of pollution monitoring, and in particular relates to a system and a method for measuring the transfer of atmospheric deposition heavy metals in sediments. Background technique [0002] Currently, heavy metals refer to metal elements with a relative density equal to or greater than 5.0. Heavy metals are generally not easy to leach with water and cannot be decomposed by soil microorganisms, but can be absorbed by soil microorganisms and plants by adsorbing on soil colloids, and transformed into more toxic substances through the food chain or other methods, seriously endangering human health. Heavy metals in soil mainly come from atmospheric deposition and heavy metals entering the soil with solid waste, sewage, and agricultural materials. In the initial stage of heavy metal accumulation in soil, it is not easy to be noticed and concerned by people, which is a potential hazard. However, once the soil is pollu...

AI Technical Summary

Problems solved by technology

At present, there is no system for measuring the transfer of heavy metals in sediments by atmospheric deposition, and it is impossible to detect the transfer of heavy metals, making it more difficult to prevent and control heavy metal pollution

[0003] Through the above analysis, the existing problems and defects of the existing technology are: currently there is no system for measuring the transfer of heavy metals in sediments in atmospheric deposition, and the detection of heavy metal transfer cannot be realized, making it more difficult to prevent and control heavy metal pollution
