Regular dust measurement at the workplace is recommended to check the quality of the current safety measures.   <\/p>\n\n\n\n<p><br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>The &#8220;aerodynamic diameter&#8221; &#8211; its role as a descriptive variable<\/strong><\/h3>\n\n\n\n<p>The term <strong>&#8220;aerodynamic diameter&#8221; <\/strong>is a<strong> <\/strong>size specification to describe the<strong> particle size of (suspended) solid particles<\/strong>.  <\/p>\n\n\n\n<p>In this functional description of the transport and deposition of dust, the diameter of a sphere with a density of 1g\/cm\u00b3 is used as a reference object.  <\/p>\n\n\n\n<p>Its sinking speed in still air is equated with that of the particle under consideration. A small <strong>example<\/strong> follows to illustrate this:   <\/p>\n\n\n\n<p><br>If a particle has an aerodynamic diameter of 10\u00b5m, it has the same sinking speed as a sphere with a diameter of 10\u00b5m and a density of 1g\/cm\u00b3. From this it can be deduced that a dust particle with a diameter of 1\u00b5m has an approximate sink time of around seven hours.   <\/p>\n\n\n\n<p><br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Differentiation of particulate matter according to particle size<\/strong><\/h3>\n\n\n\n<p>The <strong>terms &#8220;fine dust&#8221;<\/strong> and <strong>&#8220;total dust&#8221;<\/strong> are outdated, but still commonly used definitions for <strong>A-dust<\/strong> (fine dust) and <strong>E-dust (total dust)<\/strong>.  <\/p>\n\n\n\n<p><br><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>A-dust<\/strong><\/h4>\n\n\n\n<p>The general description<strong> <\/strong>for the dust fraction of <strong>A-dust<\/strong> defines <strong>respirable<\/strong> <strong>dust<\/strong><em>.<\/em> This means that these dust particles can penetrate into the alveoli (pulmonary alveoli) and cause serious damage to health. An aerodynamic diameter of up to 10\u00b5m is assumed. <\/p>\n\n\n\n<p><br><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>E-dust<\/strong><\/h4>\n\n\n\n<p><strong>The term for the dust fraction of E-dust<\/strong> describes the <strong>inhalable dust<\/strong>, i.e. the solid particles that enter the respiratory tract through the mouth and nose.  <\/p>\n\n\n\n<p><br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>DIN EN 481<\/strong><\/h3>\n\n\n\n<p>The regulation<strong> DIN EN 481<\/strong> with the name <strong>&#8220;Workplace atmosphere. Determination of the particle size distribution for the measurement of airborne particles<\/strong> contains the definitions and areas of application of various fractions and is required in conjunction with<strong> Technical Rules for Hazardous Substances (TRGS) <\/strong>in occupational health and safety.<\/p>\n\n\n\n<p>Two conventions are defined there, which have specific separation characteristics: PM2<sub>.<\/sub>5 and PM10. These can be used to carry out comparable measurements. The values 2.5 and 10 describe the diameter of the particles.<\/p>\n\n\n\n<p><br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Health hazards from dust for humans<\/strong><\/h3>\n\n\n\n<p>If solid particles enter the airways and lungs, they can cause serious damage. The lung tissue becomes irritated and can scar, which can lead to permanent <strong>impairment<\/strong> and <strong>chronic shortness of breath<\/strong> with long-term exposure.   <\/p>\n\n\n\n<p>However, in addition to all the dangers, there is also a positive aspect to consider. In medicine, the aerodynamic diameter and the resulting inhalation potential are utilized. In this context, inhaled medications are being developed that deliver the active ingredient to the affected areas of the lungs and help to provide relief (e.g. in the case of bronchitis).    <\/p>\n\n\n\n<p><br><\/p>\n\n\n\n<p>Sources:<br>[1]: Source contribution image: own source<br>[2]: https:\/\/www.pharmazeutische-zeitung.de\/ausgabe-402006\/physikalische-einfluesse-steuern-die-pulmonale-deposition\/<br>[3]: https:\/\/www.dguv.de\/staub-info\/was-ist-staub\/a-staub\/index.jsp<br>[4]: https:\/\/www.toxikologie.de\/fileadmin\/user_upload\/GT\/Arbeitskreise\/Regulatorische_Toxikologie\/Veranstaltungen\/2006\/2006_Koch.pdf<br>[5]: https:\/\/macau.uni-kiel.de\/servlets\/MCRFileNodeServletdissertation_derivate_00004563\/121213_Stolte_Aerodynamische.pdf<br>[6]: https:\/\/www.bgrci.de\/fileadmin\/BGRCI\/Veranstaltungen\/Sifa_Tagungen_HH_Soltau_und_Timmendorfer_Strand_2018\/Neumann_Allgemeiner_Staubgrenzwert.pdf<br>[7]: https:\/\/www.lgl.bayern.de\/downloads\/gesundheit\/arbeitsplatz_umwelt\/doc\/feinstaub_begriffe.pdf<br>[8]: https:\/\/www.dguv.de\/medien\/ifa\/de\/pub\/grl\/pdf\/2009_058.pdf<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dust particle measurement for fine dust The SG10-2A can be used to measure dust particles very precisely, taking into account the respective size specification of the &#8220;aerodynamic diameter&#8221;.
