Health effects depend on ozone precursors, which is a group of pollutants, primarily generated during the combustion of fossil fuels. Ground-level ozone is created by nitrous oxides reacting with organic compounds in the presence of sunlight. [22]

The ozone at ground level is primarily from fossil fuel precursors, but methane is a natural precursor, and the very low natural background level of ozone at ground level is considered safe. This section examines the health impacts of fossil fuel burning, which raises ground level ozone far above background levels.
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 ...
The Environmental Protection Agency is delaying plans to tighten air quality standards for ground-level ozone — better known as smog — despite a recommendation by a scientific advisory panel ...
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]
Ozone was originally found to be damaging to grapes in the 1950s. The US EPA set "oxidants" standards in 1971, which included ozone. These standards were created to reduce agricultural impacts and other related damages. Like lead, ozone requires a reexamination of new findings of health and vegetation effects periodically.
Climate change leads to a warmer ground temperature and its effects include earlier snowmelt dates, drier than expected vegetation, increased number of potential fire days, increased occurrence of summer droughts, and a prolonged dry season. [56] Wood smoke from wildfires produces particulate matter that has damaging effects to human health. [57]
