Scientists at the University of California Davis have developed a machine that may improve air monitoring technology, according to a release. The new system is capable of determining which air pollution sources will give off the most toxic particles.

Officials can use the device to save money by focusing on unnatural sources of the toxic particles instead of others, according to the researchers.

To show the importance of separately sensing particles, the group used a mass-spectrometer to collect 10  particle samples that were analyzed and then separated. Lab mice inhaled the samples and were then monitored for signs of toxicity. The results showed different responses based on where the sample was collected.

Development of the system, which appears to be unnamed, was funded by the California Air Resources Board and the Electric Power Research Institute.
