EMRP project ENV02 PartEmission designs new experiment to aid mercury emissions legislation

A new experiment, designed as part of the EMRP PartEmission project, will help meet emerging requirements for measuring pollutants from automotive exhaust emissions.

More exacting emissions and ambient air regulations for mercury have been introduced under a European Directive as the detrimental effects of this element on human health and the environment have been increasingly recognised. Enforcing this legislation requires highly accurate and traceable measurements of the mass concentration of mercury vapour at saturation in air. However, the most accurate way of doing this is still under debate. 

In EMRP project PartEmission 'Emerging requirements for measuring pollutants from automotive exhaust emissions' an experiment was designed by project partners from the Joint Research Centre - Institute for Research Materials and Measurements (JRC-IRMM) with support from NPL and has produced fully SI traceable results. The determined values are expected to underpin a future international agreement on how to accurately define the mass concentration of mercury vapour at saturation in air.
