Ozone's effect on signalling in animals may therefor become more significant than its direct affect as an antibiotic at higher concentrations. [8] Developments of techniques capable of more accurately monitoring ozone levels inside cells will enable investigation of endogenous ozone in cells, perhaps clarifying how cells use endogenous ozone.

Reaction with daylight ultraviolet (UV) rays and these precursors create ground-level ozone pollution. Ozone is known to have the following health effects at concentrations common in urban air: Irritation of the respiratory system, causing coughing, throat irritation, and/or an uncomfortable sensation in the chest.
Ozone depletion is not a primary cause of climate change, however there exists a physical science connection between the two phenomena. The Earth's atmospheric ozone has two major effects on the Earth's temperature balance. Firstly, it absorbs solar ultraviolet radiation, leading to the heating of the stratosphere.
Ozone depletion would magnify all of the effects of UV on human health, both positive (including production of vitamin D) and negative (including sunburn, skin cancer, and cataracts). In addition, increased surface UV leads to increased tropospheric ozone, which is a health risk to humans. [61]
For the last few decades, scientists studied the effects of acute and chronic ozone exposure on human health. Hundreds of studies suggest that ozone is harmful to people at levels currently found in urban areas. [78] [79] Ozone has been shown to affect the respiratory, cardiovascular and central nervous system. Early death and problems in ...
[86] [87] High ozone concentrations irritate the lungs and thus affect respiratory function, especially among people with asthma. [81] People who are most at risk from breathing in ozone air pollution are those with respiratory issues, children, older adults and those who typically spend long periods of time outside such as construction workers ...
Schematic drawing, causes and effects of air pollution: (1) greenhouse effect, (2) particulate contamination, (3) increased UV radiation, (4) acid rain, (5) increased ground-level ozone concentration, (6) increased levels of nitrogen oxides. An air pollutant is a material in the air that can have many effects on humans and the ecosystem. [61]
In women, while overall effects on fertility do not appear significant there is an association between increased exposure to PM 10 and early miscarriage. Exposure to smaller particulate matter, PM 2.5, appears to have an effect on conception rates in women undergoing IVF but does not affect live birth rates. [2] Ozone structure showing three ...
