Heavy metal pollution risk assessment system

Abstract

The invention discloses a heavy metal pollution risk assessment system, which comprises the following steps: firstly, acquiring historical pollution data of a research target under a set duration and a plurality of corresponding pollution data at a current acquisition moment through a heavy metal acquisition subsystem, and acquiring corresponding input data and output data; then, constructing a pollution risk assessment model based on the historical pollution data, constructing a plurality of matrixes with weights according to the plurality of pollution data, and obtaining a plurality of corresponding assessment levels with weights through the pollution risk assessment model; calculating a corresponding risk level in combination with the input data and the output data, displaying and storing the corresponding data, and performing corresponding early warning according to the risk level, so that the system can be suitable for heavy metal risk assessment under multiple research targets, and can improve the risk assessment efficiency in combination with historical data and the corresponding input and output data .

Description

technical field [0001] The invention relates to the technical field of heavy metal pollution risk prevention and control, in particular to a heavy metal pollution risk assessment system. Background technique [0002] Risk assessment is widely used in many aspects such as natural disasters, resource utilization, and climate change. In the field of environmental protection, risk assessment methods have been used in the risk management of toxic and harmful chemicals. Heavy metals are toxic chemical pollutants that enter the environment in large quantities and have serious impacts. They not only cause serious pollution to the ecological environment, but also directly threaten human health through the food chain. The current common risk assessment only focuses on a single research target such as farmland, and the risk assessment of heavy metals only stays on the currently collected data, resulting in limited assessment data and reducing the efficiency of risk assessment. Conten...
