effects of indoor air pollution

In the 1600s, ants were controlled with mixtures of honey and arsenic. Indoor air pollutants also cause symptoms like sneezing, coughing, nasal congestion, watery eyes, fatigue, headaches, difficulty breathing, and dizziness. Research on exactly how indoor air quality impacts unborn babies and their mothers is limited. This important book will be of interest to a wide-ranging audience of science, health, engineering, and building professionals, government officials, and members of the public. Chrysotile asbestos, also known as white asbestos, is the predominant commercial form of asbestos. Steam pipes, boilers, and furnace ducts insulated with an asbestos blanket or asbestos paper tape. Front. Sick building syndrome occurs in buildings where people experience negative health effects, but the source of these symptoms cannot be identified. Patching and joint compounds for walls, ceilings, and textured paints. Both major and minor repairs must be done only by a professional trained in methods for safely handling asbestos. Author content. The U.S. population, on the average, spends as much as 90% of its time indoors. A typical used mattress may have from 100,000 to 10 million mites in it. Asbestos cement roofing, shingles, and siding. Methylene chloride is also converted to CO in the body and can cause symptoms associated with CO exposure. Changes in the climate affect the air we breathe, both indoors and outdoors. Pulmonary and respiratory diseases. In the modern home, many organic chemicals are used as ingredients in household products. In recent years, there have been numerous advertisements for ion generators that destroy harmful indoor air pollutants. Battery-powered CO detectors provide continuous protection and do not require recalibration in the event of a power outage. We make recommendations for Government and local authorities, and provide guidance for families. Mold Assessment Methods. These products contain asbestos that could be inhaled and are required to be labeled as such. Ventilate your indoor space, including the kitchen, attic and basement. These cooking practices are inefficient, and use fuels and technologies that produce high levels of household air pollution with House dust mites also can be detected using diagnostic tests that measure the presence and infestation level of mites by combining dust samples collected from various places inside the home with indicator reagents [7]. In the United States, EPA regulates pesticides under the pesticide law known as the Federal Insecticide, Fungicide, and Rodenticide Act. Found insideThe book covers new and updated technologies, such as combustion improvement and after treatment, SCR, the NOx reduction method, Ox scrubber, DPF, Electrostatic precipitator, Plasma PM decomposition, Plasma NOx reduction, and the Exhaust ... Asbestos is also a cause of indoor air pollution. Radon found in the house is the second leading cause of lung cancer in America, according to the US National Cancer Institute. Higher levels of uranium are often contained in rock such as light-colored volcanic rock, granite, dark shale, and sedimentary rock containing phosphate. These include moldlike fungi, as well as other fungi such as yeasts and mushrooms. Another group of arthropods linked to asthma is house dust mites. The following summarizes several important regulations that affect lead-hazard reduction projects. Effect on indoor air pollution. ), Is Cardboard Biodegradable? In the small number of studies that have specifically looked at asbestos exposure in children, there is no indication that younger people might develop asbestos-related diseases more quickly than older people. The EPA also estimates that approximately 3,000 lung cancer deaths occur each year in nonsmokers due to ETS. Use alternative products, such as wood panel products not made with UF glues, lumber, or metal. No standard numeric guidelines exist for assessing whether mold contamination exists in an area. Effects of indoor air pollution can cause children to develop health issues at a very early stage. Residential Lead-Based Paint Hazard Reduction Act of 1992, Title X [62]. Some of these chemicals may be emitted from aerosol products, dry-cleaned clothing, paints, varnishes, glues, art supplies, cleaners, spot removers, floor waxes, polishes, and air fresheners. These materials may release asbestos fibers if damaged, repaired, or removed improperly. Opening the windows is the easiest and simplest way to reduce indoor air pollution. 0: 370. doi: 10.3389/fenvs.2021.709718 These activities make it easier for children to be exposed to lead. According to the American Lung Association (ALA) [33], breathing low levels of CO can cause fatigue and increase chest pain in people with chronic heart disease. Long-term effects may include an increased risk of cancer. Professional testing for lead in paint is recommended. This book deals with several air pollution issues air pollution chemistry; air pollutant emission control; radioactive pollution and d) indoor air quality. Sometimes the treatment is simply eliminating the person's exposure to the source of the pollution, if it can be identified. It is classified as a known human carcinogen by the World Health Organization,and there have been several cases where it has also caused cancer. According to Lyon [7], house dust mites thrive in homes that provide a source of food and shelter and adequate humidity. Indoor air pollution: protecting air quality to prevent asthma. Some of the known triggers of intrinsic asthma are infections, such as cold and flu viruses, exercise and cold air, industrial and occupational pollutants, food additives and preservatives, drugs such as aspirin, and emotional stress. These orchards are often turned into subdivisions as cities expand and sprawl occurs. The Community Environmental Health Resource Center reports that cockroach debris, such as body parts and old shells, trigger asthma attacks in individuals who are sensitized to cockroach allergen [6]. Inhaling small amounts of ozone can result in chest pain, coughing, shortness of breath, and throat irritation. Every year, indoor air pollutants kill more people than HIV/AIDS and malaria combined, ranging from 3.5-4.3 million each year, while negatively impacting the health of millions more. Learn more about indoor air pollutants and sources of: If too little outdoor air enters indoors, pollutants can accumulate to levels that can pose health and comfort problems. The four main cyclodiene pesticides—aldrin, dieldrin, chlordane, and heptachlor—were used to guard soil and seed against insect infestation and to control insect pests in crops. A number of indoor environmental asthma triggers are biologic pollutants. Is Stainless Steel Sustainable? Many reproduce via the production and dispersion of spores. This condition causes the lungs to swell and produce excess mucus, making it difficult to breathe. A layer of gas-permeable material under the foundation, The foundation (usually 4 inches of gravel), Plastic sheeting over the foundation, with all openings in the concrete foundation floor sealed and caulked, A gas-tight, 3- or 4 inch vent pipe running from under the foundation through the house to the roof. While cooking at home, it is important to ensure the gas … Effects with particular interest concerning allergic and respiratory health disorders. Common methods for sampling for mold growth include bulk sampling techniques, air sampling, and collection of settled dust samples. damp and mould. Radon-222 is the radon isotope of most concern to public health because of its longer half-life (3.8 days). The emission rate for both resins will change over time and will be influenced by high indoor temperatures and humidity. CPSC [40] notes that formaldehyde is a colorless, strong-smelling gas. 11. However, if you have an old home that was constructed a long time ago, the risks for asbestos are much greater than that of a newer home. Thoroughly clean the home (including floors and walls) after animal removal. 35, 1465–1477. When too little outdoor air enters indoors, pollutants can accumulate to levels that can pose health and comfort problems. Driving in cars, flying in airplanes, engaging in recreational activities, and being exposed to environmental pollutants all pose varying degrees of risk. Surface sampling in mold contamination investigations may also be used when a less destructive technique than bulk sampling is desired. The mobility of radon gas is much greater than are uranium and radium, which are solids at room temperature. Synthetic fragrances, perfumes, air fresheners and deodorizers use substances that are largely unregulated and are not monitored by the government. A recent Institute of Medicine (IOM) review of the scientific literature found sufficient evidence for an association between exposure to mold or other agents in damp indoor environments and the following conditions: upper respiratory tract symptoms, cough, wheeze, hypersensitivity pneumonitis in susceptible persons, and asthma symptoms in sensitized persons [15]. Issued by OSHA, these regulations address worker safety, training, and protective measures. The ion detector generally is only available through laboratories. maintaining heating, ventilating, and air conditioning (HVAC) systems; changing HVAC filters frequently, as recommended by manufacturer; keeping gutters and downspouts in working order and ensuring that they drain water away from the foundation; routinely checking, cleaning, and drying drip pans in air conditioners, refrigerators, and dehumidifiers; increasing ventilation (e.g., using exhaust fans or open windows to remove humidity when cooking, showering, or using the dishwasher); venting clothes dryers to the outside; and. 2. Ozone Found insideReviews and research papers describe air pollution in five main contexts: Monitoring, Modeling, Risk Assessment, Health, and Indoor Air Pollution. The book is recommended to experts interested in health and air pollution issues. Lead-based paint was used extensively on exteriors and interior trim-work, window sills, sashes, window frames, baseboards, wainscoting, doors, frames, and high-gloss wall surfaces, such as those found in kitchens and bathrooms. CDC data show that deteriorated lead-based paint and the contaminated dust and soil it generates are the most common sources of exposure to children today. There are still billions of people who use these types of fuels to heat their homes on a daily basis. Many reports and studies indicate that the following populations may be disproportionately impacted by indoor asthma triggers, secondhand smoke, mold, radon and other indoor pollutants: EPA's Indoor Environments Division (IED) provides guidance and programs to help build the capacity of communities to understand and avoid indoor and outdoor health impacts. Environmental Tobacco Smoke or Secondhand Smoke Dry cleaned clothes containing highly toxic substances such as trichloroethylene and perchloroethylene are known to cause cancer. It also causes cancer, among other risks to the body. Formaldehyde is a colorless gas with a characteristic pungent smell. With an emphasis on passive sampling, this volume focuses on the environmental monitoring for common gaseous pollutants. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns. Title X calls for the reduction of lead in federally supported housing. The Global Burden of Disease is a major global study on the causes and risk factors for death and disease published in the medical journal The Lancet. The National Cancer Institute (NCI) [ 36], states that ETS is the combination of two forms of smoke from burning tobacco products: The physiologic effects of ETS are numerous. Pesticides Asthma is more common in children than in adults, with nearly 1 of every 13 school-age children having asthma [3]. Thus, radon can leave rocks and soil, move through fractures and pore spaces, and ultimately enter a building to collect in high concentrations. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. The health effects of indoor air pollution have caused increasing attention in recent years. This includes children, older adults, and people with long-term (chronic) illnesses. In the last several years, a growing body of scientific evidence has indicated that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities. Surface water sources typically contain little radon because it escapes into the air. Additionally, passive smoking can lead to coughing, excess phlegm, and chest discomfort. 5. Certain immediate effects are similar to those from colds or other viral diseases, so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution. While pollutants commonly found in indoor air can cause many harmful effects, there is considerable uncertainty about what concentrations or periods of exposure are necessary to produce specific health problems. Serious effects of Indoor Air pollution. Most individuals are exposed to small amounts of asbestos in daily living activities; however, a preponderance of them do not develop health problems. Ventilate the home well by opening doors and windows and installing an exhaust fan(s). Use appliances that have electronic ignitions instead of pilot lights. Numerous studies show that arsenic sticks to children’s hands when they play on treated wood, and it is absorbed through the skin and ingested when they put their hands in their mouths. A flight is canceled to Delhi because smog is too dense. It is estimated that an additional 7,500 to 15,000 hospitalizations resulting from increased respiratory infections occur in children younger than 18 months of age due to ETS exposure. In addition, high temperature and humidity levels can increase the concentration of some pollutants. Indoor air pollution caused by the use of biomass energy in heating and cooking adversely affects the health status of household members. 7. Around 3 billion people still cook using solid fuels (such as wood, crop wastes, charcoal, coal and dung) and kerosene in open fires and inefficient stoves. Chemical Pollutants Common pollutants, such as pollen, originate from plants and can elicit symptoms such as sneezing, watery eyes, coughing, shortness of breath, dizziness, lethargy, fever, and digestive problems. According to WHO sick building syndrome is a reaction to an indoor environment like excessive exposure to a known contaminant or a defective ventilation system. People spend 65 to 90 percent of their time in indoor and maximum of that time in home. Pesticides help to control or kill pests which may include insects, rodents, and organisms such as fungi and bacteria. As with fire deaths, the risk for unintentional CO death is highest for the very young (ages 4 years and younger) and the very old (ages 75 years and older). Mold Standards. This individual will take samples for analysis and submit them to an EPA-approved laboratory. The latter type of resin generally emits formaldehyde at a considerably slower rate than those containing UF resin. A national study by Crain et al. Medium-density fiberboard should be in conformance with ANSI A208.2-1994 and hardwood plywood with ANSI/HPVA HP-1-1994. According to the National Fire Protection Association (NFPA), CO-related nonfire deaths are often attributed to heating and cooking equipment. Lead compounds also were used as driers in paint and window-glazing putty. These products are found in sprays, sticks, powders, crystals, balls, and foggers. Such groups include the young, the elderly, and the chronically ill, especially those suffering from respiratory or cardiovascular disease [1]. The health effects of these chemicals are varied. Arsenic is on EPA’s short list of chemicals known to cause cancer in humans. For this reason, it is important to pay attention to the time and place symptoms occur. Houses typically draw less than 1% of their indoor air from the soil. Worker Protection When Conducting Mold Assessment and Mitigation Projects. Ambient air pollution is a major environmental threat to human health. Asbestos is the leading cause of indoor air pollution. Arsenic The main source of high-level radon pollution in buildings is surrounding uranium-containing soil. These products are not likely to release asbestos fibers unless sawed, drilled, or cut. 5) and “sick build- Found insideThe impact of air pollution on human health is currently of international concern. A comprehensive review of the subject is given in this volume, which complements the previous title covering air quality management. Never use gas-powered equipment, charcoal grills, hibachis, lanterns, or portable camping stoves in enclosed areas or indoors. The highly volatile and semi-volatile chemicals used in these products can cause indoor air pollution. If you have a home that was built prior to the ban of asbestos, it is important to make sure there is none still lingering within the home. Figure 5.1 shows mold growth in the home. To prevent the onset and progress of asthma, prioritising indoor air quality is key. 4. Indoor air pollution of the farming environment, characterised by an excess of bio-contaminants, might partly explain such effects. Various governmental and private organizations have, however, proposed guidance on the interpretation of fungal measures of environmental media in indoor environments (quantitative limits for fungal concentrations). Indoor environment conditions contribute greatly to human wellbeing, as most people spend around 90% of their time indoors, mainly at home or in the workplace [1]. The only way to determine which building components are coated with lead paint is through an inspection for lead-based paint. New study on effects of indoor air pollution on human skin uses NativeSkin® models. For example, the American Academy of Pediatrics recommends that infants under 1 year of age are not exposed at all to chronically moldy, water-damaged environments [18]. Atmos. The Merriam-Webster Dictionary [56] defines lead as “a heavy soft malleable ductile plastic but inelastic bluish white metallic element found mostly in combination and used especially in pipes, cable sheaths, batteries, solder, and shields against radioactivity.” Lead is a metal with many uses. Provided the surrounding outdoor environment is free from effluent, smoke, volatile organic compounds or dust, it offers free circulation of fresh air that reduces indoor air pollution. Therefore, the only way to accurately determine the amount of lead present in older paint is to have it analyzed. Pollutants can be up to 100 times higher in indoor air than outdoor air! “Indoor air pollution refers to chemical, biological and physical contamination of indoor air. Found insideThis book presents WHO guidelines for the protection of public health from risks due to a number of chemicals commonly present in indoor air. (And Should We Stop Camping? 5. CDC twenty four seven. Older, substandard housing low income families can be particularly prone to mold problems because of inadequate maintenance (e.g., inoperable gutters, basement and roof leaks), overcrowding, inadequate insulation, lack of air conditioning, and poor heating. The Harvard study is one of several that suggest air pollution is affecting COVID-19 mortality. A certified inspector or risk assessor can test paint, soil, or lead dust either on-site or in a laboratory using methods such as x-ray fluorescence (XRF) analyzers, chemicals, dust wipe tests, and atomic absorption spectroscopy. We summarise in this section the effects of air pollution found in the rural setting as its comprehension could lead to a better understanding of respiratory and allergic diseases. A potential asbestos problem both inside and outside the home is that of vermiculite. Click here for lead action levels. Adverse health responses attributed but not proven to be caused by VOCs in nonindustrial indoor environments include (1) irritant effects resulting from mucous membrane irritation, (2) systemic effects such as fatigue and difficulty concentrating, and (3) toxic effects such as carcinogenicity.21, 22, 23 The strongest association has been with VOCs causing mucous membrane irritation.22, 23 Improve the quality of indoor air pollutants may become airborne during renovations, whether main of...
