Ozone may provide environmentally safe protection for grains
... They used five-gallon plastic pails and 50-gallon steel
drums, storage bins filled with grain, and buried mesh bags all filled with grain and a known number of grain-eating bugs to test ozone's killing efficacy. The team's previous studies on ozone flow and effectiveness in eliminating insects were done e...
