OZONE TO PROTECT GRAIN
A new study finds ozone can eliminate insects in grain storage facilities without harming food quality or the environment. Purdue University researchers the gas is an alternative to fumigants -- coming at a time when an international treaty bans the use of ozone-layer harming chemicals currently used to rid food storage facilities of insects.
When ozone is used for killing grain insects, it lasts for a short period of time and does not damage the environment or the grain, Purdue scientists report. "Ozone has a very short half-life and we're using relatively low dosages, but enough to kill an insect," said Linda Mason, Purdue entomology associate professor.
"The chemicals currently used can kill everything in and around the grain bin, including people. With ozone, we're not generating ozone at deadly concentrations, and we have better control over it when it's present."
