Keep a close eye on mercury

Gas instrumentation manufacturer Ion Science says its Mercury Vapour Indicator (MVI) can provide rapid and reliable mercury detection during decommissioning, demolition, repurposing or refurbishment of industrial plant, laboratories and other premises.

Making sense of sensor arrays

Research at Oregon State University is working towards the development of an electronic "nose" capable of monitoring air quality, detecting safety threats, and measuring gases in a patient's breath.

Describing pollutant distribution in 3d

A team led by environmental physicist Stefan Schreier at the University of Natural Resources and Applied Life Sciences in Vienna is attempting to build up a better picture of nitrogen dioxide pollution in the city. The work includes the first attempts to describe how this pollution is distributed in the vertical axis, from street-level upwards, as well as the use of data from satellite measurements.
