Short summary

Exposure to mercury (Hg), is a significant issue from a human health perspective. Understanding the chemistry that leads to exposure is important. We have developed a laser-based sensor for the detection of gas-phase elemental mercury, Hg(0). The instrument is capable of fast in situ measurement of Hg(0) at ambient levels. The RAMIX experiment intercompared atmospheric Hg measurement systems. We typically saw good agreement for measurements of Hg(0) but not for total oxidized mercury.
