Abstract: The aims of this study were to estimate the total amount of mercury released to theenvironment during 60 years of gold mining (1867–1926) at Gympie, Queensland, Australia and to measurethe mercury levels in soil samples surrounding the mining activity. We estimated that 1902 tonnes of mercurywas released to the environment and about 1236 tonnes of which was released to the air. The mean mercury inthe soil samples in the vicinity of the Scottish battery varied from 1.07 to 99.26 µg g⁻¹ as compared to 0.075 µgg⁻¹ as background mercury concentrations. The maximum mercury concentration measured in sediments ofthe Langton Gully was 6.12 µg g⁻¹. These results show that large amount of mercury was used in this areaduring gold mining. Since mining is active in the area and Langton Gully flows into Mary River, we therefore,recommend that mercury concentration in air and fish should be monitored.
