A large fraction of the bacteria found in indoor air and dust are shed from humans. Even if you are not a smoker.
As particulate matter with an aerodynamic diameter below 25 µm PM.
Identify two specific indoor air pollutants. Basic Information on Pollutants and Sources of Indoor Air Pollution. Carbon Monoxide CO Cookstoves. Lead Pb Nitrogen Dioxide NO 2 Pesticides.
Radon Rn Indoor Particulate Matter. Secondhand Smoke Environmental Tobacco Smoke. Volatile Organic Compounds VOCs Wood Smoke.
7 Common Indoor Air Pollutants 1 Pollutant. Carbon monoxide CO Carbon monoxide is an odorless invisible gas. Its produced by the incomplete.
Radon Radon is an odorless colorless gas that is found everywhere in low levels. It is made naturally as. Indoor air pollution is on the rise due to our everyday activities and use of modern household products.
Appliances deodorants room fresheners and scented paints are contributing to air pollution inside our homes. Indoor smoking poor ventilation and pipe leaks are also creating problems for the quality of air in our homes. The exposure these pollutants are contributing to long-term health complications.
Indoor pollutants can be placed into two groups biologic and chemical. Biologic Pollutants Biologic pollutants include bacteria molds viruses animal dander cat saliva dust mites cockroaches and pollen. For developed nations such as the US the two most dangerous indoor air pollutants are tobacco smoke and radon.
Even if you are not a smoker. Indoor air pollutants can have NATURAL sources such as radon mold dust and pet dander. They can be human-made sources such as VOCs.
Or particulate s such as. John Ray Cuevas. Primary air pollutants are air pollutants emitted directly from sources to the atmosphere.
Some of the examples of primary pollutants are NO x from automobile exhaust carbon monoxide carbon dioxide sulfur dioxide nitrogen oxide nitrogen dioxide most hydrocarbons and most suspended particles. Identify TWO air pollutants released during the burning of biomass indoors for cooking and. Click card to see definition.

An air quality monitor such as the Laser Egg Chemical has sensors that can measure pollutants such as PM 25 and VOCs. That means it can track any outdoor pollution that may be creeping inside or help you understand if new products are emitting something thats irritating your airways. By using a monitor you can make more calculated observations about the exact location and cause of pollution.
Indoor air pollution There are myriad forms and sources of indoor pollution including combustion tobacco smoke stoves fireplaces and wood stoves household products construction materials biologic agents eg microbes pets off-gassing from water and soil gas. In particular soil gas is the origin of most indoor radon. Concentrations commonly observed in indoor air.
In addition to the 17 chemicals included in the tool a literature review and expert consultation identified a range of other indoor air pollutants of concern Annex 2. Information about the methods relevant for these chemicals and particulate matter is also included in this publication. As particulate matter with an aerodynamic diameter below 25 µm PM.
A large fraction of the bacteria found in indoor air and dust are shed from humans. Among the most important bacteria known to occur in indoor air are Mycobacterium tuberculosis Staphylococcus aureus Streptococcus pneumoniae. Second it detects and identifies the existence of peak indoor PM 25 and PM 1 levels as a result of stove use.
Third it seeks to clarify whether the level of indoor air pollution is originating from indoor or outdoor sources. Finally it seeks to determine the extent to which these emissions are coming from a specific category of stoves. Those that are certified as a Smoke Exempt Appliance by the UKs.
Usually primary pollutants are substances directly emitted from a process such as ash from a volcanic eruption the carbon monoxide gas from a motor vehicle exhaust or sulphur dioxide released from factories. Secondary pollutants are not emitted directly. Rather they form in the air when primary pollutants react or interact.
Outdoor air pollution is a complex mixture of several pollutantsIn 1970 Congress passed the Clean Air Act that established national air pollutant standards for 6 criteria pollutants. Ozone respirable particulate matter PM sulfur compounds lead carbon monoxide CO and nitrogen dioxide NO2. Sensory irritation of the eyes and upper airways is a specific effect often related to exposure to indoor air pollutants Alarie 1973.
2004 and needs particular attention. Sensory irritation may be induced by specific chemicals but also by factors such as too low relative humidity of air.
