Abstract
|
|
|
In this study, mercury, methylmercury and heavy metals in sediment from the lake Andong were analyzed, along with the estimation of mercury flux between sediments and water in the lake Andong. Average mercury concentrations in sediments sampled in 2009~2011 were 155.0±71.9 ng/g, 211±62 ng/g and 198±6.88 ng/g, respectively. The average methylmercury concentration were 1.85±1.09 ng/g (2009) and 3.49±1.79 ng/g (2011), and %methylmercury, the fraction of methylmercury in total mercury were 1.17±0.39% and 1.77±0.94%, respectively. Heavy metal (Zn, Cd, Pb, Cu) concentrations of the sediments exceeded ERL (Effect Range Low) level of US NOAA (National Oceanic and Atmospheric Administration)’s sediment quality criteria. Estimated mercury sedimentation flux was found to be 83.7 ng/cm2
·yr and mercury diffusion flux was estimated as 1.24 ng/cm2 ·yr
