The Antarctic ozone hole is an area of the Antarctic stratosphere in which the recent ozone levels have dropped to as low as 33 percent of their pre-1975 values. [47] The ozone hole occurs during the Antarctic spring, from September to early December, as strong westerly winds start to circulate around the continent and create an atmospheric ...
Stomach cancer is more common in Japan due to its high-salt diet. [9] [11] Dietary recommendations for cancer prevention typically include weight management and eating a healthy diet, consisting mainly of "vegetables, fruit, whole grains and fish, and a reduced intake of red meat, animal fat, and refined sugar."
Ozone in the troposhere is determined by photochemical production and destruction, dry deposition and cross-tropopause transport of ozone from the stratosphere. [2] In the Arctic troposphere, transport and photochemical reactions involving nitrogen oxides and volatile organic compounds (VOCs) as a result of human emissions also produce ozone resulting in a background mixing ratio of 30 to 50 ...
The United States Food and Drug Administration (FDA) prohibits all medical uses of ozone "in any medical condition for which there is no proof of safety and effectiveness", stating "ozone is a toxic gas with no known useful medical application in specific, adjunctive, or preventive therapy. For ozone to be germicidal, it must be present in a ...
The signs and symptoms of refeeding syndrome can vary based on the severity of electrolyte disturbances, including weakness, arrhythmias, and respiratory difficulty. Hypophosphatemia, a key feature of refeeding syndrome, may lead to muscle weakness, heart failure, and impaired diaphragmatic function, while hypokalemia and hypomagnesemia can ...
The amount of ozone manufactured for use in the food and other industries is reflected in the considerable effort placed on producing it efficiently in high performance ozone generators. [17] Where non-targeted antibiotic action is required, such as in water purification, it is widely used.
Ozone remains depleted in the midlatitudes of both hemispheres. The global-average total column ozone amount for the period 1997-2001 was approximately 3% below the pre-1980 average values. Models capture the observed long-term ozone changes in northern and southern midlatitudes.
The ozone hole was much more seen as a "hot issue" and imminent risk compared to global climate change, [13] as lay people feared a depletion of the ozone layer (ozone shield) risked increasing severe consequences such as skin cancer, cataracts, [23] damage to plants, and reduction of plankton populations in the ocean's photic zone. This was ...
