Health Effects of Ozone in the General Population | US EPA

· Effects of ozone on daily mortality have been detected even when study days are restricted to those with a 24hour average ozone concentration below 60 ppb (approximately equivalent to an 8hour average below 90 ppb). In one study, hospital admissions for respiratory causes appear to follow a linear relationship down to background levels. (Figure 9). Limited exposureresponse modeling …

NASA Ozone Watch: Latest status of ozone

· Ozone is a colorless gas. Chemically, ozone is very active; it reacts readily with a great many other substances. Near the Earth’s surface, those reactions cause rubber to crack, hurt plant life, and damage people’s lung tissues. But ozone also absorbs harmful components of sunlight, known as “ultraviolet B”, or “UVB”.

How is Ozone Formed? | SCDHEC

Ozone is a molecule made up of three oxygen atoms, often referenced as O is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NO X ) and Volatile Organic Compounds (VOC), which are also known as reaction can occur both near the ground and high in the atmosphere.

Nasa Ozone Watch: Ozone facts

· Ozone is a gas made up of three oxygen atoms (O 3 ). 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. In the lower atmosphere (the troposphere) near the Earth’s surface, ozone is created by chemical reactions between air ...

Ozone depletion Wikipedia

Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth''s atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth''s polar regions. The latter phenomenon is referred to as the ozone are also springtime polar tropospheric ozone depletion ...
