An overview of atmospheric mercury monitoring at Auchencorth Moss, the UK EMEP Supersite in southern Scotland: trends, patterns and a source analysis
Centre for Ecology & Hydrology, Bush Estate, Penicuik, Midlothian, EH26 0QB, UK
Speciated atmospheric mercury has been measures semi-continuously at the Auchencorth Moss field site in southern Scotland since 2004. Here we present an analysis of the data from 2009 to 2011 for the three species: elemental, gaseous oxidized (GOM) and particulate bound (PBM) mercury. Measurements of elemental mercury were made using the Tekran 2537A analyser and the Tekran 1130 and 1135 speciation units were used to collect GOM and PBM respectively. The data shows no upward or downward trend for elemental mercury, with yearly average concentrations between 1.3 and 1.5 ng m-3. We will continue the work started in Kentisbeer et al, 2010 to analyse the effect of wind direction on the mercury species, making further of air mass back trajectories and introducing cluster analysis to investigate the effects of longer rangetransport to the site.
Key words: elemental mercury / gaseous oxidized mercury / particulate bound mercury / monitoring
