Abstract
Disclosed is a method for detection of air-water exchange flux of organic contaminants, which passively and continuously collects contaminants at consecutive points close to a sea surface microlayer, acquires the freely dissolved concentration at the consecutive points of the air and water body close to a water body surface microlayer, and obtains the air-water exchange flux of the contaminants through fitting a self-developed model, wherein the consecutive points include a plurality of sampling points along a height direction above an air-water interface and a plurality of sampling points along a depth direction below the air-water interface. The present invention can be applied to determine the air-water body exchange flux of organic contaminants.
