Guidelines also cover indoor mould and dampness (WHO, 2009) and emissions of gases and chemicals from furnishings and building materials that collect indoors (2010).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.The document also summarizes the available information on the conditions that determine the presence of mould and measures to control their growth indoors.
The WHO is working on producing an updated set of guidelines on selected pollutants.
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.
Two sound level monitors recorded concurrently for 24 hours at the ICU central stations and adjacent to patients.
Sample values to determine levels generated by equipment and external noise were also recorded in an empty ICU side room.
The guidelines aim to eliminate or reduce exposure to these pollutants, and are targeted at public health professionals, specialists and authorities involved in the design of buildings and indoor materials and products.
They provide a scientific basis for legally enforceable standards.
Pollutants covered include benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons, radon, trichloroethylene and tetrachloroethylene.
These substances are often found indoors in concentrations high enough to merit concern.
The WHO air quality guidelines offer guidance on reducing the effects on health of air pollution.
This book presents revised guideline values for the four most common air pollutants - particulate matter, ozone, nitrogen dioxide and sulfur dioxide - based on a review of the accumulated scientific evidence.
In 2014, WHO issued the first-ever health-based guidelines on clean fuels and technologies for household cooking, heating and lighting.Tags: Adult Dating, affair dating, sex dating
