Abstract

The estimated annual emissions and measured ambient concentrations of metals in the United Kingdom 1980-2007 have been compared. Both quantities show decreases over this time period and exhibit a broad correlation, although many obfuscating factors impose significant noise on this relationship. A generalised least regression analysis has been performed for each metal, to estimate the sensitivity of measured ambient concentrations to emissions, and to predict ambient concentrations in the absence of emissions. This process has shown that metals emitted mainly from diffuse sources, such as transport, show the highest ambient concentrations to emissions sensitivities. The results also provide some evidence to suggest that vanadium emissions may be over-estimated.
