ABSTRACT
In this study, emulsion and mine water samples were collected from the Daliuta area, and the
emulsion composition was analyzed. The typical pollutants in the emulsion were triethanolamine,
sodium benzoate, sodium nitrite, and sodium hyponitrotriacetate. Furthermore, migration and
transformation studies were conducted with respect to these typical pollutants in the emulsion. When
the mine water was passed through the aeration zone of a water accumulation leaching device, the
pollutant concentrations considerably decreased, resulting in significant adsorption and migration
effects. Subsequently, the adsorption effect was significantly reduced. The adsorption rate of sodium
benzoate and sodium hyponitrotriacetate increased with an increase in the emulsion concentration on
the 30th day. The adsorption rate of sodium nitrite in 1 L mine water with 20 mL emulsion on the 30th
day was 86.4%. The noncarcinogenic health risk assessment and exposure index (EI) model calculations
of the simulated mine water containing emulsion revealed that all the hazard quotient (HQ) and EI
values of carcinogens were >1. Furthermore, reference pollutant concentrations under the specific
conditions of HQ and EI were obtained. These study findings are expected to provide scientific data
support for local governments to strengthen geological environment management in mining areas.
