What effect can stratospheric ozone depletion have on the environment?
What effect can stratospheric ozone depletion have on the environment?
Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV) radiation that reaches Earth’s surface, which increases the rate of skin cancer, eye cataracts, and genetic and immune system damage.
What will happen if the concentration of ozone in the stratosphere decreases?
Ozone in the stratosphere absorbs most of the ultraviolet radiation from the Sun. Without ozone, the Sun’s intense UV radiation would sterilize the Earth’s surface. These reduced ozone levels have increased the amount of harmful ultraviolet radiation reaching the Earth’s surface.
How does ozone in the stratosphere protect human health?
The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earth’s surface.
Does ozonated water kill fungus?
An ozone level of 0.4 ppm for 4 minutes has been shown to kill any bacteria, virus, mold and fungus. Mold and mildew are easily controlled by Ozone present in air and in water. Giardia and Cryptosporidium cysts are susceptible to Ozone but not affected by normal levels of Chlorine.
How long does ozone last in bottled water?
20 to 30 minutes
Does ozone kill E coli?
Results from this study show that ozone treatment was effective in both E. coli and Listeria spp.
Can you bottle tap water and sell it?
You can sell it directly to consumers in bottles as well as other containers, such as: tetra packs and cartons. water coolers.
Can I bottle my own water?
You can store your own water if you use the proper containers and follow proper sanitation methods. What is the shelf life of water you store yourself? In theory indefinitely, but this assumes you do not contaminate the water at some point or it is not contaminated before you fill up a container with it.
Is Bottled Water profitable?
As you might assume, the profit margins in the bottled water industry are exceedingly high; the normal profit margin on bottled water is an astounding 50 to 200%. Ironically, as select corporations become richer because of these profit margins, many in the developing world lack access to clean water.
