As shown in previous studies, the litter from the polluted site, which had endured high levels of atmospheric nitrogen oxides and ozone, had higher nitrogen content than litter from the clean site.

But it can promote the formation of ground - level ozone, which irritates the lungs and at high levels makes it dangerous for people with respiratory problems to be outside.

The formation of large areas of high pressure in the lower atmosphere both lowers ozone levels, by squeezing the ozone layer above, and may provide the very cold conditions in which ozone destruction is greatest.

Ozone was recorded at 160 micrograms per cubic metre, a level considered moderate - to - high on the UK's pollution index and almost twice as high as Aberdeen, which had the UK's worst ozone levels at time of wriOzone was recorded at 160 micrograms per cubic metre, a level considered moderate - to - high on the UK's pollution index and almost twice as high as Aberdeen, which had the UK's worst ozone levels at time of wriozone levels at time of writing.

Another example would be ozone levels which become more unhealthy with high temperatures or the heat index.

The electron belt is on top of the proton belt, the so called van Allen belts, then there is the upper ionosphere which tends negative and the lower ionosphere that tends positive, and this coupling impact, and space particles attracted to opposing sings and a dance of high energy particles that come with O2 splitting and ozone level increases, namely toward the tropics, while the closing isobars bring particles to the poles... all mean that flaring has a HUGE electrical meaning.

Crops, which tend to be situated in areas with high ozone levels, would be particularly stunted because they are fertilized.

Similar negative effects occur with worsening air pollution — higher levels of ground - level ozone smog and other pollutants that increase with warmer temperatures have been directly linked with increased rates of respiratory and cardiovascular disease — food production and safety — warmer temperatures and varying rainfall patterns mess up staple crop yields and aid the migration and breeding of pests that can devastate crops — flooding — as rising sea levels make coastal areas and densely - populated river deltas more susceptible to storm surges and flooding that result from severe weather — and wildfires, which can be ancillary to increased heat waves and are also responsible for poor air quality (not to mention burning people's homes and crops).

Hotter summers and more frequent fires will lead to more cases of heat stroke and deaths, and to higher levels of near - surface ozone and smoke, which would cause more «code red» air quality days.

High ozone levels downstream of pollution sources can cause elevated OH radical concentrations, which in turn increases the concentration of condensable species and thus the potential for nucleation.
