Any city that has little to no internal combustion engine traffic, or is not downwind from a fossil fuel powered power plant will have low ozone. These will be very small cities. Any city that has constant wind will have low ozone. These are usually located in mountain passes and will also be small.
The positives are quite simple: Oxygen enables life. Life is good. The negatives may include: Too much oxygen can offset the balance in the ozone layer, which protects us from the sun. This works in reverse, if there is not enough oxygen, the ozone may be lost. If the ozone is lost, the earth would have NO shielding from the sun's Ultra Violet Ray (UV rays). If this happens, earth could conservatively reach extremes as high as several hundred degrees F. in the day, and as low as hundreds below 0*
the Low Low is for a Very Low level Alarm, or an emergency status. the Low is just a low level switch who activate any normal output
Low density is when a country has a low number of population.
Gasses have an incredibly low density, less than a liquid or a solid.
low immunity
Ozone level is the concentration of ozone. It should not be very low.
Low ozone concentrations are caused in part by chlorofluorocarbons, or CFCs.
ozone layers are low when they feel like it
Ozone layer hole is the low concentration of ozone. It is present in both hemisphere.
The ozone depletion is at the poles. It is due to the low temperatures there.
Ozone gas in the troposphere is very low. It is a pollutant.
The ozone levels in 1998 were low. It was because of the CFC's.
The hole in ozone is at the poles. It is due to the low temperature there.
Ozone is depleted at Antarctica. It is because of low temperatures.
The ozone depletion requires low temperatures. It is because ozone is depleted in Antarctica.
It depletes rapidly at low temperatures. This is the reason for ozone depletion at poles.
The ozone hole is actually the low concentration of ozone. It is pretty big over Antarctica.
