What are emissions? Where do they come from?

Emissions is the term used to describe the gases and particles which are put into the air or emitted by various sources.

emissions brochureRestaino et al (Restaino 1995) has shown that ozonated water is highly effective in killing both gram positive and gram negative food associated bacteria.

The Restaino study shows that ozonated water can effectively kill spoilage organisms. (Pseudomonas aeruginosa and Zygosaccharomeyces bacilli), Faecal contaminants (Enterococcus faecallis and Escherichia coli) and food bourne pathogens (listeria monocytogenes, Bacillus cereus, Salmonella typhimurium, Yersinia enterocolitica and Staphylococcus areus). More than 5 log reduction of Salmonella typhimurium and Escherichia coli was reached instantaneously in ozonated water with or withouemissionst the addition of 20 ppm of soluble starch.

Among gram-positive bacteria, listeria monocytogenes, was signifficantly the more sensitive (5 log immediate reduction). More than 4.5 log units each of Candida albicans and Zygosaccharomeyces bacilli cells were killed instantaneously in ozonated water, whereas less than 1 log unit of Aspergillus niger spores were inactivated after 5 minutes of exposure.

In the Restaino study, the gram negative bacteria were substantially more sensitive to ozonated water than the gram positive bacteria either in the absence or in the presence of added organic material.
