I always see the weather say this… but does that mean the air quality is bad due to pollen and other allergens in the air, or does that mean the air quality is bad due to car pollution? I assume pollen, because I see this alert when it hasn’t rained for a while so I assume all of the pollen is just floating around in the air.

Most Big Towns & Metro Areas- have Air Pollution monitors- scattered all over Them. And these Report to a Centralized Location- several times a Day, how much "stuff" there is in the Air at THAT given time. When the Weather Service forecasts a stretch calm, dry weather coming up, They can Predict ( based on PAST Recordings of JUST such Occasions)- what the Air Quality is Going to be Like, in the coming day or Two. In the Spring, -Pollen is usually the main Culprit affecting Air Quality- because Everything Blooming or Leafing out, & a LOT of people have Allergies. In the Summer ( & sometimes- winter), calm air and Heat ( or Cold) Inversions can set up over an Area- trapping the Car & Industrial Exhaust over it. And the Weather Service can see these conditions "Coming", and thus Issue Air Quality Alerts as They are Needed. So it ALL Depends, on the Time of year, & the Conditions present, -WHAT kind of Alert will be issued- for any given Area…

Where i live there is a code orange air quality alert, of course its memorial day and i want to go in my pool and go outside but I’m scared it’s not safe. Any info would be great!

■"Unhealthy for Sensitive Groups" AQI is 101 - 150. Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.

The parag above is from an epa website. Code orange means unhealthy for sensitive groups.

Does cutting a vast, vast number of trees down affect the oxygen found in the atmosphere? Does it deteriorate air quality?

Trees breathe in carbon dioxide (a greenhouse gas) and breathe out oxygen, so massive deforestation could increase the atmosphere’s carbon dioxide and reduce the oxygen.

I play trombone in my band and I would like to be able to play more measures without having to breathe every two measures. I also want to be able to play louder without having to take in more air. Can someone help me improve my air quality?

The best thing for you to do is breathing exercised. Getting "The Breathing Gym" would probably help you out immensely. The longer you play, the more air you should be able to use.

at what time in the morning is the air quality best to practice pranayam daily?

I am planing to relocate a good place in California. If anybody know about a good city that has good neighborhood, clean air quality, good schools and neat recreational parks. I would like relocate a good place that does not have desert fever or California fever. I am looking to the north side of the California, especially near by Sacramento or San francisco area. Please give me an idea about a good place. Thanks in advance

Air quality standards are the maximum allowable amounts of various pollutants. The federal government and some state governments issue these standards. Find and state the current standards that have been issued by the EPA. find the amount of pollutants in a city outside the United States. How do these values compare with the current EPA standards?

use perhaps the Riemann’s dzeta function

I have a small office in a building full of artists, musicians etc… The office has a very strong smell to it. It almost smells like very strong crayons. I would like to test the air quality in the space. I feel as though there might by some noxious fumes coming from somewhere.
Any recommendations on how to test the air quality for pollutants? No need to test for allergens.

This is a stretch, but OSHA requires all work places to keep a list of chemicals and their hazards on site. This location sounds like a school and I doubt you will find the HAZMAT sheets on site, but you could contact Windsor Newton and any other artist paint manufacturers for the hazard sheet on their product. The toxic paint thinners of old have been replaced with newer stuff with less fumes. Walk around the studios and check the labels. You may find they need ventilation when used. Clay would also have an odor. I personally love that smell. Just about any diverse art center has it. Your other option would be to hire a safety engineer to check your work space. Radon testers and carbon monoxide detectors are the only air quality testers I have seen for the general public.

I am looking for objective info about air quality (pollen count, particles from the Iceland volcano). Not interested in just mood music saying everything is great and that we are more at risk from slipping in the bath tub. My grandfather has asthma and other lung problems (no, he never smoked) so air quality is an important issue when planning a trip. Thanks. It’s ok if the website is in French.

Sadly, Paris and London are among two of the worst cities in Western Europe as far as air quality goes. APHEA (Air Pollution and Health - A European Approach) is the authority on this subject. Their information is somewhat technical, but according to http://ec.europa.eu/research/success/en/env/0267e.html "in a region such as Ile de France for instance, sulphur dioxide and particle emissions (especially caused by diesel engines) lead to an excess mortality of more than 400 cases a year: between 260 to 350 deaths caused by cardiovascular accidents and 50 to 80 due to severe respiratory complications"

How do you test the air quality outdoors, especially in cities. Please use scientific explanation and included were u got the information. thanx:)

One of the most well-used devices in air quality monitoring is the passive sampler, because they are relatively cheap and easy to use with no utilities needed. This makes them desirable in rural areas. They measure cumulative exposures to specified contaminants like NOx and SO2.

Air quality is a multidisciplinary thing, drawing from expertise in a number of sciences, the most obvious being chemistry and meteorology. For example, this Canadian company described in the reference uses atmospheric scientists, meteorologists and engineers for air quality testing and reporting. Their webpage goes into greater detail.
