What is the common name for the tropospheric ozone?
Formation. The majority of tropospheric ozone formation occurs when nitrogen oxides (NOx), carbon monoxide (CO) and volatile organic compounds (VOCs), react in the atmosphere in the presence of sunlight. NOx, CO, and VOCs are called ozone precursors.
Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. The total amount of effective halogens (chlorine and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).
- The emission of ODS account for roughly 90% of total depletion of ozone layer in stratosphere. These gases are carried to the stratosphere layer of atmosphere where ultraviolet radiations from the sun break them to release chlorine (from CFCs) and bromine (from methyl bromide and halons).
- Depletion of the ozone layer has consequences on humans, animals and plants. This typically results from higher UV levels reaching us on earth. Research confirms that high levels of UV Rays cause non-melanoma skin cancer. Additionally, it plays a major role in malignant melanoma development.
- Ozone is a gas made up of three oxygen atoms (O3). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation.
Although the concentration of the ozone in the ozone layer is very small, it is vitally important to life because it absorbs biologically harmful ultraviolet (UV) radiation coming from the sun.
- Schönbein had noticed the same characteristc smell during his experiments, that Van Marum had tried to identify earlier. He called this gas 'ozone', which is distracted from ozein; the Greek word for scent. Generally, the discovery of ozone is ascribed to Schönbein.
- Although the concentration of the ozone in the ozone layer is very small, it is vitally important to life because it absorbs biologically harmful ultraviolet (UV) radiation coming from the sun.
- High in the atmosphere, some oxygen (O2) molecules absorbed energy from the Sun's ultraviolet (UV) rays and split to form single oxygen atoms. These atoms combined with remaining oxygen (O2) to form ozone (O3) molecules, which are very effective at absorbing UV rays.
Ozone therapy is a form of alternative medicine treatment that purports to increase the amount of oxygen in the body through the introduction of ozone. Various techniques have been suggested, with purported benefits including the treatment of cancer, AIDS, and multiple sclerosis, among others.
- Benefits of Ozone Hair Treatment: On coming in contact with the roots of the hair strands, ozone rejuvenates and fortifies the hair follicles to strengthen and nourish the hair and scalp. This therapy improves blood circulation and eliminates any microbial infection present in the scalp and hair.
- Ozone May Help Herniated Disc Pain. March 9, 2009 -- An experimental treatment that involves injections of ozone gas into the spine is showing promise for the relief of herniated disc-related lower back pain.
- When contaminants such as odors, bacteria or viruses make contact with ozone, their chemical structure is changed to less odorous compounds. As more ozone attacks the remaining compounds, the odor is eventually destroyed. This process is called oxidation. Ozone essentially reverts back to oxygen after it is used.
