Presentation transcript:

Volatile Organic Compounds (VOC) Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOCs are emitted by a wide array of products numbering in the thousands. Organic chemicals are widely used as ingredients in household products. Paints, varnishes & wax all contain organic solvents, cleaning, disinfecting, cosmetic, degreasing and hobby products. Fuels are made up of organic chemicals. All of these products can release organic compounds while you are using them & to some degree, when they are stored. EPA's Office of Research and Development's "Total Exposure Assessment Methodology (TEAM) Study" (Volumes I through IV, completed in 1985) found levels of about a dozen common organic pollutants to be 2 to 5 times higher inside homes than outside, regardless of whether the homes were located in rural or highly industrial areas. TEAM studies indicated that while people are using products containing organic chemicals, they can expose themselves and others to very high pollutant levels, and elevated concentrations can persist in the air long after the activity is completed.

Sources of VOCs Household products, including: Paints, paint strippers and other solvents Wood preservatives Aerosol sprays Cleansers and disinfectants Moth repellents and air fresheners Stored fuels and automotive products Hobby supplies Dry-cleaned clothing Pesticide Other products, including: Building materials and furnishings Office equipment such as copiers and printers, correction fluids and carbonless copy paper Graphics and craft materials including glues and adhesives, permanent markers and photographic solutions.

Health Effects Health effects may include: Eye, nose and throat irritation ,headaches, loss of coordination and nausea damage to liver, kidney and central nervous system. Some organics can cause cancer in animals, some are suspected or known to cause cancer in humans. Key signs or symptoms associated with exposure to VOCs include: Conjunctival irritation Nose and throat discomfort Headache Allergic skin reaction Dyspnea Declines in serum cholinesterase levels Nausea Emesis Epistaxis Fatigue Dizziness

Contd….. The ability of organic chemicals to cause health effects varies from those that are highly toxic, to those with no known health effect. As with other pollutants, the extent and nature of the health effect will depend on many factors including level & time exposed. Among the immediate symptoms that some people have experienced soon after exposure to some organics include: Eye and respiratory tract irritation headaches dizziness visual disorders and memory impairment

Levels in Homes Studies have found that levels of several organics average 2 to 5 times higher indoors than outdoors. During and for several hours immediately after certain activities, such as paint stripping, levels may be 1,000 times background outdoor levels.   Steps to Reduce Exposure Increase ventilation when using products that emit VOCs. Do not store opened containers of unused paints and similar materials within the school/home Formaldehyde, one of the best known VOCs, is one of the few indoor air pollutants that can be readily measured. ( a must in Ply) Use integrated pest management techniques to reduce the need for pesticides. USE ECOCARAT TILES …….ONLY ONE of its kind in world. Made in Japan
