JSI has expertise in the field of Hg analysis, toxicity, and fate. JSI was strongly involved in the preparation of the Minamata Convention and thus will support the dissemination of the outcomes of the project directly to stakeholders. The project coordination will be performed by Dr. Milena Horvat, Head of the Department of Environmental Sciences, from JSI, who has much experience in coordinating large EU funded research projects and with research in metrology in chemistry and with the EMRP through, JRPs ENV02 PartEmission and ENV51 MeTra where she was a work package leader. In this project, JSI is more or less involved in all WPs.
Activity descriptions:
In addition to other activities in WP1, JSI, with support from VTT, Optoseven, VSL, PSA and CNR, will produce a method for the on-site traceable generation of HgCl2 at sub-ng/m3 levels, including portable reference gases for atmospheric (oxidised) mercury measurements (1.3.3).

In WP2 JSI together with LGC and UPPA will select at least 3 of the most common/widely used methods for the selective determination of Hg(II) and Hg(0), in the gas phase, that has been selectively trapped in denuders, sorbent traps and impinger solutions. JSI will then evaluate these methods for determining Hgtot /Hg(II) in materials specific for Hg(II) trapping via selective reduction/derivatisation and/or thermal desorption-CV-AAS/CV-AFS/MS detection. We will also investigate a method for Hg(II) species specific determination within gaseous traps using APCI-MS. The novel APCI-MS methodology will be used for Hg(II) species specific determination at environmentally relevant concentrations (i.e. typically a few tens of pg-m -3) for PM bound Hg(II). JSI will develop SI traceable methods to accurately determine Hgtot isotopic ratio signatures using MC-ICP-MS, from species specific Hg(II) and Hg(0) gases from denuders, sorbent traps, impinger solutions. Additionally, traceable methods to accurately determine Hgtot isotopic ratio signatures in PM using femto-Sec-LA-ICP-MS or MC-ICP-MS will be developed (from A2.2.8).

In WP3 JSI will investigate Hg speciation in stack gas emissions. Together with other partners will produce optimised and validated sampling methods for gaseous Hg species using traceable reference standards for Hg(0) and Hg(II)). JSI will then submit the review of the methods to EURAMET as Deliverable 6. (Contact: This email address is being protected from spambots.

In WP4, JSI will test and validate existing methods for on-line Hg and sorbent trap measurement a) in the atmosphere under different environmental conditions, b) in the emission monitoring in a coal fired power plant and c) cement clinker production facility. JSI together with UPPA will apply the traceable isotope measurements developed in WP2 in the coal fired power plant and cement clinker production facility.
