Ozone is a poisonous gas that can build up in the air in...?

Question

in dense cities. Thus, there are many enviromental initiatives to lower the amount of ozone in the air. One way you can make Ozone, however, is by baking bread. The nice smell you associate with baking bread is actually due, in part, to ozone. If ozone is poisonous, why is baking bread not considered a dangerous activity.

Now I want serious answers not..oh it bread blah blah blah. Dont be stupid...seriuosly.

Answer 1

Ozone is only considered to be dangerous in high enough concentrations. I searched and it appears that the California Health Standard for ozone levels is set at 90 ppb.

I read somewhere that if you can identify the smell of ozone in the air, the concentration is high enough that prolonged exposure would be bad for your health. Since the smell of baking bread does not noticably smell of ozone, I would think that the amount of ozone caused by this activity is very small.

Answer 2

You sound very angry when it comes to mother earths well being. This is a good thing. Believe me Ozone is not caused by baking bread. Besides most of our ovens today have extractor fans that suck that due into a filter which is agitated by a fan. The amount of ozone generated by on ore two plumes of due from baked bread is so minute that it will have to take at least a billion plumes of due to cause damage. Now what you should be worried about is the amount of vehicles on the road, and industry. This is where the real problem lies. We are now building huge filtration plants in industry to minimize amount of monoxide and other harmful gasses that cause damage to our earth. So little lady you have not to worry, things are being sorted out as you read this.

The highest levels of ozone in the atmosphere are in the stratosphere, in a region also known as the ozone layer between about 10 km and 50 km above the surface. Here it filters out the shorter wavelengths (less than 320 nm) of ultraviolet light (270 to 400 nm) from the Sun that would be harmful to most forms of life in large doses. These same wavelengths are also responsible for the production of vitamin D, which is essential for human health.

Low level ozone (or tropospheric ozone) is regarded as a pollutant by the World Health Organisation[11]. It is not emitted directly by car engines or by industrial operations. It is formed by the reaction of sunlight on air containing hydrocarbons and nitrogen oxides that to form ozone directly at the source of the pollution or many kilometers down wind.

Ozone reacts directly with some hydrocarbons such as aldehydes and thus begins their removal from the air, but the products are themselves key components of smog.

As well as having an impact on human health (see below) there is also evidence of significant reduction in agricultural yields due to increased ground-level ozone and pollution which interferes with photosynthesis and stunts overall growth of some plant species.[13][14]

Although ozone was present at ground level before the industrial revolution, peak concentrations are far higher than the pre-industrial levels and even background concentrations well away from sources of pollution are substantially higher.[15][16] This increase in ozone is of further concern as ozone present in the upper troposphere acts as a greenhouse gas, absorbing some of the infrared energy emitted by the earth. Quantifying the greenhouse gas potency of ozone is difficult as it is not present in uniform concentrations across the globe. However, the most recent scientific review on the climate change (the IPCC Third Assessment Report[17]) suggests that the radiative forcing of tropospheric ozone is about 25% that of carbon dioxide.

There is a great deal of evidence to show that high concentrations (ppm) of ozone, created by high concentrations of pollution and daylight UV rays at the earth's surface, can harm lung function and irritate the respiratory system [11][18]. There has also been shown to be a connection between increased ozone caused by thunderstorms and hospital admissions of asthma sufferers [19]. Air quality guidelines

Answer 4

air toxins takes position even as an undesirable gas or particle (or too a lot of a needed gas or particle) pollutes the gaseous mix all of us comprehend as air. This has been happening for the time of the history of the planet. although, with the creation of the business revolution and the linked exponential boom in inhabitants, air toxins has skyrocketed. the biggest causes of air toxins are transportation, power era, and market. The above polute the air with techniques from the freeing Hydrocarbons into the air.

Answer 5

Are you sure of this? I mean have you checked it out w/a reliable source or two? I have never heard this but here are some thoughts... yes, it could be because it's bread, and we love it/need it no matter what it does. Or many people may not know this happens. Or the output could be sooo small it doesnt really have that big of an impact. Hope this helps!
