50. No. The most important means for avoiding adverse health effects is the prevention (or minimization) of persistent dampness and microbial growth on interior surfaces and in building structures. These guidelines review the evidence on health impacts from indoor dampness and exposure to microbes such as mould, fungi and bacteria which emit spores into indoor air. [6] The NAAQS are health based and the EPA sets two types of standards: primary and secondary. The National Emissions Standards for Hazardous Air Pollutants cover many other chemicals, and require the maximum achievable reduction that the EPA determines is feasible. They can be read in conjunction with Air quality guidelines for Europe, 2nd edition, which is still the authority on guideline values for all other air pollutants. World Health Organization These substances are often found indoors in concentrations high enough to merit concern. The guidelines also explain how well-designed, well-constructed, well-maintained building envelopes are critical to the prevention of microbial growth and moisture. The guidelines also include recommendations against the use of unprocessed coal as a household fuel, and against the use of kerosene as a household fuel, in the light of health and safety risks.

View lists of pre-registered speakers for May 20, 21 & … What is an Air Contaminant Pollutant? The WHO is working on producing an updated set of guidelines on selected pollutants. The public must be informed if ozone levels exceed the following thresholds, Nitrogen dioxide 1 ppb = 1.91 ug/m3 Sulphur dioxide 1 ppb = 2.66 ug/m3 Ozone 1 ppb = 2.0 ug/m3 Carbon monoxide 1 ppb = 1.16 ug/m3 Benzene 1 ppb = 3.24 ug/m3, PO Box 3000 Johnstown Castle Estate Wexford, Y35 W821 Tel. Fact Sheet, Fact Sheet – Air Quality Designations for the 2010 Primary Nitrogen Dioxide (NO. The Clean Air Act, which was last amended in 1990, requires EPA to set National Ambient Air Quality Standards (40 CFR part 50) for pollutants considered harmful to public health and the environment.The Clean Air Act identifies two types of national ambient air quality standards. In order to protect our health, vegetation and ecosystems, EU directives set down air quality standards in Ireland and the other member states for a wide variety of pollutants. Guidelines also cover indoor mould and dampness (WHO, 2009) and emissions of gases and chemicals from furnishings and building materials that collect indoors (2010). These guidelines make recommendations for reducing health risks from exposure to ambient emissions of gases and chemicals that may infiltrate and collect indoors, as well as from chemicals that may be used in building materials or furnishings that contribute to indoor air pollution. Most recently, WHO Guidelines for indoor air quality - household fuel combustion, set limits on emissions from cooking and heating stoves, as well as recommendations regarding clean fuel use. Ambient air quality limits serve to indicate what levels of exposure to pollution are generally safe for most people, including the very young and the elderly, over their lifetimes. In response, the European Union has developed an extensive body of legislation which establishes health based standards and objectives for a number of pollutants present in the air. Limit values of CAFE Directive 2008/50/EC. [25] A complete list of FRMs and FEMs is available. Four "daughter" directives lay down limits for specific pollutants: The Ambient Air Quality and Cleaner Air for Europe (CAFE) Directive (2008/50/EC) was published in May 2008. The U.S. National Ambient Air Quality Standards (NAAQS, pronounced \'naks\) are limits on atmospheric concentration of six pollutants that cause smog, acid rain, and other health hazards. Pollutants covered include benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons, radon, trichloroethylene and tetrachloroethylene. 271 of 2002), the Ozone in Ambient Air Regulations 2004 (S.I. Learn more. 180 of 2011). Air quality standards View real-time air quality up-to-date information for air monitoring locations.. Another recommendation addresses the need for policies that prioritize substantial health benefits during the transition from use of solid, polluting fuels to clean fuels and technologies, especially in low-income and rural households. The limit and target values for both Directives are outlined below. [5] The Clean Air Act requires the EPA to set US National Ambient Air Quality Standards (NAAQS) for the six CAPs. The primary standards are designed to protect the health of 'sensitive' populations such as asthmatics, children, and the elderly. "[24], EPA has set NAAQS for six major pollutants listed as below. In order to protect our health, vegetation and ecosystems, EU directives set down air quality standards in Ireland and the other member states for a wide variety of pollutants. WHO guidelines for protecting public health are formulated on the basis of the review. Air quality standards and objectives At a glance Air quality limits and thresholds are fundamental to effective air quality management. [1], The EPA National Exposure Research Laboratory can designate a measurement device using an established technological basis as a Federal Reference Method (FRM) to certify that the device has undergone a testing and analysis protocol, and can be used to monitor NAAQS compliance. 1211 Geneva 27 Secondary standards are designed to protect public welfare, damage to property, transportation hazards, economic values, and personal comfort and well-being from any known or anticipated adverse effects of a pollutant. The secondary standards are concerned with protecting the environment. These rules include how we should monitor, assess and manage ambient air quality. The document also summarizes the available information on the conditions that determine the presence of mould and measures to control their growth indoors. [1] Established by the United States Environmental Protection Agency (EPA) under authority of the Clean Air Act (42 U.S.C. Approved new methods are formally announced through publication in the Federal Register. WHO sets recommended limits for health-harmful concentrations of key air pollutants both outdoors and inside buildings and homes, based on global synthesis of scientific evidence.

[7], The EPA established the NAAQS according to Sections 108 and 109 of the U.S. Clean Air Act, which was last amended in 1990. [27], Michigan Department Of Environmental Quality, January 2004. 53 of 2004) and S.I. 33 of 1999. [2], The six criteria air pollutants (CAP), or criteria pollutants, for which limits are set in the NAAQS are ozone (O3), atmospheric particulate matter, lead, carbon monoxide (CO), sulfur oxides (SOx), and nitrogen oxides (NOx).
