Ozone layer depletion causes increased UV radiation levels at the Earth’s surface , which is damaging to human health. ... Aquatic life just below the water’s surface, the basis of the food chain, is particularly adversely affected by high UV levels. UV rays also affect plant growth, reducing agricultural productivity.
What are the effects of ozone depletion on the environment?
Ozone layer depletion causes increased UV radiation levels at the Earth’s surface , which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.
What are the environmental and economic effects of ozone depletion?
Ozone layer depletion causes increased UV radiation levels at the Earth’s surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders. ... UV rays also affect plant growth, reducing agricultural productivity.
What are the causes and effects of ozone depletion?
The main effect of ozone depletion is an increase in UV-B rays reaching the earth’s surface. Causes : chlorofluorocarbon
What are the causes of ozone depletion?
Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants —are released into the atmosphere (see details below).
How does ozone depletion affect human life?
Ozone layer depletion causes increased UV radiation levels at the Earth’s surface , which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders. ... UV rays also affect plant growth, reducing agricultural productivity.
What is effect of ozone?
Ozone can inflame the lung’s lining . ... Breathing ground-level ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema, and asthma. Ozone also can reduce lung function and inflame the lining of the lungs.
What are the advantages and disadvantages of ozone layer?
The ozone layer protects life on earth by absorbing harmful ultraviolet radiation . As the layer thins, the upper atmosphere grows colder, causing winds in the stratosphere and in the troposphere below to shift, displacing jet streams and storm tracks.
How ozone depletion can be prevented?
How can we protect the ozone layer? Avoid the consumption of gases dangerous to the ozone layer , due to their content or manufacturing process. Some of the most dangerous gases are CFCs (chlorofluorocarbons
What is the importance of ozone layer?
The ozone layer protects the Earth against most UVB coming from the sun . It is always important to protect oneself against UVB, even in the absence of ozone depletion, by wearing hats, sunglasses, and sunscreen. However, these precautions will become more important as ozone depletion worsens.
What are the effects of ozone depletion on plants and animals?
Scientists have demonstrated a direct reduction in phytoplankton production due to ozone depletion-related increases in UVB . UVB radiation has been found to cause damage to early developmental stages of fish, shrimp, crab, amphibians, and other marine animals.
How harmful is ozone?
When inhaled, ozone can damage the lungs . Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath and, throat irritation. It may also worsen chronic respiratory diseases such as asthma as well as compromise the ability of the body to fight respiratory infections.
What level of ozone is safe?
The Food and Drug Administration (FDA) requires ozone output of indoor medical devices to be no more than 0.05 ppm . The Occupational Safety and Health Administration (OSHA) requires that workers not be exposed to an average concentration of more than 0.10 ppm for 8 hours.
What level of ozone is harmful?
These ozone molecules form the ozone layer and are commonly referred to as “good ozone.” At concentrations as high as 12,000 ppb (the EPA considers anything over 70 ppb to be unhealthy for human health and welfare) this ozone protects and shields people, trees, crops, property, and microorganisms from the harmful ...
Is ozone stronger than bleach?
One of the most powerful disinfectants is ozone. In fact, when compared to the most popular disinfectant chlorine bleach, the effects of ozone sanitation are 1000 times stronger than chlorine bleach and kills any and all bacteria and viruses within 2 seconds!
What are 3 disadvantages of using ozone to treat water?
- Solubility and Activity. If the dose of ozone is too low, some of the germs and especially those that can form cysts may survive. ...
- Reactivity. Ozone’s reactivity is what makes it such a great disinfectant. ...
- Expense. ...
- Residuals and Byproducts.
