1 Air pollution and health Introduction:The human health effects of poor air quality are reaching, but principally affect the body's respiratory system and the cardiovascular system. Individual reactions to air pollutants depend on the type of pollutant a person is exposed to, the degree of exposure, the individual's health status and genetics. People who exercise outdoors, for example, on hot, smoggy days increase their exposureto pollutants in the air.
2 Definition:An atmospheric condition in which certain substances present in high concentration effects humans.
3 Sources and effects of air pollution: There are six air pollutants that are commonly found throughout the United States. The six pollutants are ozone, carbon monoxide, nitrogen dioxide, particulate matter, sulfur dioxide and lead.
4 Potential Health Effects* Environmental Tobacco Smoke Major Indoor SourcesPollutantRespiratory irritation, bronchitis and pneumonia in children, emphysema, lung cancer, and heart diseaseCigarettes, cigars, and pipesEnvironmental Tobacco SmokeHeadache; nausea; angina; impaired vision and mental functioning; fatal at high concentrationsUnvented or malfunctioning gas appliances, wood stoves, and tobacco smokeCarbon Monoxide
5 Unvented or malfunctioning gas appliances Eye, nose, and throat irritation; increased respiratory infections in childrenUnvented or malfunctioning gas appliancesNitrogen OxidesEye, nose, and throat irritation; headaches; loss of coordination; damage to liver, kidney and brain; various types of cancerAerosol sprays, solvents, glues, cleaning agents paints, moth repellents, air fresheners, drycleaned clothing, and treated waterOrganic ChemicalsEye, nose, and throat irritation; headache; allergic reactions; cancerPressed wood products such as plywood and particleboard; wallpaper; durable press fabricsFormaldehyde
6 Cigarettes, wood stoves, fireplaces, aerosol sprays, and house dust Eye, nose and throat irritation; increased susceptibility to respiratory infections and bronchitis; lung cancerCigarettes, wood stoves, fireplaces, aerosol sprays, and house dustRespirable ParticlesAllergic reactions; asthma; eye, nose, and throat irritation; humidifier fever, influenza, and other infectious diseasesHouse dust; pets; bedding; poorly maintained air conditioners, humidifiers and dehumidifiers; wet or moist structures; furnishingsBiological Agents (Bacteria, Viruses, Fungi, Animal Dander, Mites)Asbestosis, lung cancer, mesothelioma, and other cancersDamaged or deteriorating insulation, fireproofing, and acoustical materialsAsbestos
7 Sanding or open-flame burning of lead paint; house dust Nerve and brain damage, particularly in children; anemia; kidney damage; growth retardationSanding or open-flame burning of lead paint; house dustLead
8 Note: *Depends on factors such as the amount of pollutant inhaled, the duration of exposure and susceptibility of the individual exposed.
11 Prevention and control of air pollution Source ControlSource control is a method used to eliminate the contributor to the indoor air quality problem. Usually the most effective way to improve indoor air quality is to eliminate individual sources of pollution or to reduce their emissions. We can provide sealed combustion appliances and heating systems to eliminate the potential of combustion gasses leaking into our homes.
12 Ventilation Another approach to lowering the concentrations of indoor air pollutants in your home is to increase the amount of outdoor air coming indoors. Good ventilation assists in the removal and/or the dilution of indoor air pollutants.
13 Air Purification This method of controlling indoor air pollutants can handle both particulate matter and to some degree, gasses.
14 Some important steps you can take to reduce your indoor pollutant and allergen exposure in your home include:
15 1.Use a central vacuum system (exhausts outside) or portable sealed HEPA Vacuum Cleaners to prevent air particles and pollutants such as allergens from being dispersed into the air when cleaning. 2.Encase your bedding with Allergen Control Barriers that prevent dust mite proliferation in an area that you spend 1/3 of your day. 3.Wash bedding fabrics weekly in hot water (minimum 130° F). 4.Use surface treatments for Dust Mite Control, Animal Dander Control, Mold Control and Dust Control that will reduce your exposure to these allergens throughout the home.
16 5. Don't allow pets in the bedroom. 6 5.Don't allow pets in the bedroom. 6.Reduce your exposure to chemical gasses and vapors with natural ingredient based Household Cleaners and Personal Care Products. 7.Reduce your exposure to airborne particulates with the use of a portable HEPA Air Purification Unit or a central air filtering system.
17 8.Increase low moisture levels in the home and prevent the release of mold into the air when using humidifiers by using Germ-Free Humidifiers that kill mold and bacteria before moist air is released into the room. 9.Remove the build-up of molds and bacteria and clean your home without irritating chemicals with a home Vapor Steam Cleaning System. 10.Control excess indoor humidity with adequate ventilation and the use of dehumidifiers and air conditioners as necessary.
