To know more about Air Quality and Pollution, check the wikipedia Air Quality topic or the airnow guide to Air Quality and Your Health.įor very useful health advices of Beijing Doctor Richard Saint Cyr MD, check blog. Health alert: everyone may experience more serious health effectsĮveryone should avoid all outdoor exertion The entire population is more likely to be affected.Īctive children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion everyone else, especially children, should limit outdoor exertion. With an approximately carbon dioxide emission per person in a cinema of 0.05 m 3 /h - the CO 2 emission from 100 persons can be calculated to approximately 5 m 3 /h. Example - Carbon Dioxide Concentration in a Cinema. The units of ppm and ppb in gas systems are computed on a volume -per-volume ratio and should more accurately be termed ppmV and ppbV. )normal carbon dioxide concentration in outside air is aprox. Here i give some examples 1.Nox ppm0.001587 total exhaust (kg/hr) Total exhaust fuel flow in kg/hr + air flow in kg/hr The fuel and air flow should me measure for particular speed and load. The general public is not likely to be affected.Įveryone may begin to experience health effects members of sensitive groups may experience more serious health effectsĪctive children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion everyone else, especially children, should limit prolonged outdoor exertion However, indoor air units are not expressed as a mass-per-mass ratio, even though they are given as ppm or ppb. Answer: For each gas there are some constant to convert ppm into g/kwhr. Members of sensitive groups may experience health effects. Air quality is considered satisfactory, and air pollution poses little or no riskĪir quality is acceptable however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.Īctive children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
