Abstract

The invention relates to the environment ecological risk assessment field, and in particular relates to an organic chemical exposure level forecasting model and data analysis system for a surface water environment medium based on mass balance and dynamic subduction under the surface water environment. The organic chemicals are finally discharged into the surrounding water environment along with the modern industrial production wastewater after being treated, and volatized into atmosphere along with the water, and then enter water bottom sediment through adsorption effect or settlement effect. An exposure forecasting model system which is simple in model structure, clear in forecasting rule, easy to understand and effective is established, the model in an appropriate level can be selected according to the research aim and requirements, and the model has significance to the environment exposure and security management of the organic chemicals and the environment ecologic risk assessment.

Description

technical field

[0001] The invention relates to the field of environmental ecological risk assessment, in particular to a multi-medium exposure prediction model and data analysis method based on mass balance and dynamic reduction in a surface water environment. Background technique

[0002] In recent years, with the rapid development of my country's chemical industry, the types, output, usage and discharge of organic chemicals have increased sharply, and the waste water generated has been discharged into the sewage treatment plant, and finally into the surrounding water environment, and the organic chemicals entering the water environment system Under the action of various trans-medium migration processes, they can volatilize from the water body into the atmosphere, can be enriched in suspended particles through adsorption, and enter the sediment at the bottom of the water body through particle sedimentation. In environmental risk assessment, the exposure level of organic chem...

Examples

Embodiment 1

[0109] This example introduces specific methods for predicting exposure levels of organic chemicals in surface water environmental media.

[0110] The method for predicting exposure levels of organic chemicals in surface water environmental media specifically includes the following steps:

[0111] Step 1: Determine the main environmental phase and its sub-phases of the surface water environment system to be tested, measure and obtain the main environmental parameters of the surface water system; determine the physical and chemical parameters and background discharge parameters of the target pollutants.

[0112] Step 2. Input the obtained data into the system. Firstly, based on the Mackay multi-media fugacity model method, the fugacity capacity, degradation reaction reduction parameters, and interphase mass exchange parameters of each environmental phase are obtained, and according to the pollution in step 1, The background emission parameter of the substance is established as ...
