- The measurement of greenhouse gases is pivotal to understanding changes in the Earth's climate.
- Technological progress in several high-tech industries is enabled, if not driven, by the ability to operate at ever smaller scale. This introduces new challenges.
Trace Analysis & Electrochemistry
- Some heavy metals are known to be toxic and carcinogenic. They are emitted during industrial processes and through the abrasion and degradation of metal-containing materials. Heavy metals are present in the air in particulate matter (PM) and, in the case of mercury, also in the vapour phase.
- Measurement of mercury in the environment is of growing importance due to its high toxicity. Recent European legislation requires the UK government to monitor the mercury content of ambient air - NPL is responsible for carrying out these measurements at 13 locations around the UK as part of the UK Heavy Metals Monitoring Network.
