The legitimacy of such a value had to be based on the work of the World Health Organization (WHO). In order to reduce the then valid WHO guideline value of 150 micrograms, a working group was formed there, which made use of a meta-analysis from a five-year older report by the US Environmental Protection Agency. According to Kekul\u00e9, the meta-analysis evaluated various research projects whose parameters were completely different. Despite these completely different influencing factors, the result was &#8220;that respiratory diseases are 20 percent more frequent in households with gas cookers than in households with electric cookers&#8221;. However, no measured values could be derived from this, as very different concentrations (8 &#8211; 2500 micrograms) were found in households with gas cookers. <em>&#8220;In the absence of useful data, the experts estimated without further ado that a gas stove increases the mean annual NO concentration in the household to about 40 micrograms and suggested this value as a guideline. To date, there is no evidence that the figure has anything to do with the health effects of NO&#8221;.<\/em> Without verifying this, the EU adopted it as the legal limit. <em>&#8220;To date, there are no robust data supporting the 40 microgram limit.&#8221;<\/em><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Alexander Kekul\u00e9, Director of the Institute for Medical Microbiology of the University Hospital Halle (Saale), has written an article in the ZEIT [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[25],"tags":[30,52,53],"_links":{"self":[{"href":"http:\/\/www.retrievaldreams.de\/en\/wp-json\/wp\/v2\/posts\/270"}],"collection":[{"href":"http:\/\/www.retrievaldreams.de\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.retrievaldreams.de\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.retrievaldreams.de\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/www.retrievaldreams.de\/en\/wp-json\/wp\/v2\/comments?post=270"}],"version-history":[{"count":1,"href":"http:\/\/www.retrievaldreams.de\/en\/wp-json\/wp\/v2\/posts\/270\/revisions"}],"predecessor-version":[{"id":271,"href":"http:\/\/www.retrievaldreams.de\/en\/wp-json\/wp\/v2\/posts\/270\/revisions\/271"}],"wp:attachment":[{"href":"http:\/\/www.retrievaldreams.de\/en\/wp-json\/wp\/v2\/media?parent=270"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.retrievaldreams.de\/en\/wp-json\/wp\/v2\/categories?post=270"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.retrievaldreams.de\/en\/wp-json\/wp\/v2\/tags?post=270"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
