Quebec.<br> (attribution: <a href='https://en.wikipedia.org/wiki/Flag_of_Quebec'>wikipedia</a>) </small> </div> <p class="bigletter">Die Luftqualitätsdaten für <a href='/city/montreal/de/'>Montreal</a> und <a href='/map/quebec/de/'>Quebec</a> sind schon seit einiger Zeit verfügbar, aber wir haben kürzlich einige Fragen zur AQI-Skala erhalten, die in diesem Teil Kanadas verwendet wird. Eine davon stammt von Marie A., die fragte:</p> <blockquote> <p>Ich würde gerne wissen, warum sich der Luftqualitätsindex auf Ihrer Website vom AQI auf der Website von Montreal unterscheidet. Berechnen Sie etwas neu, um die US-amerikanischen EPA-AQI-Standards zu erfüllen? Wenn das so ist, wie? Mit welchen Daten?</p> <p>Beispiel: Datum 14. Juli, 14:00 Uhr, die meisten Indizes auf Ihrer <a href='/city/montreal/de/'>Website</a> liegen zwischen 53 und 65 (ein Index ist 37) und es soll ein Echtzeit-AQI sein. Auf der Website der <a href='http://ville.montreal.qc.ca/portal/page?_pageid=7237,74495616&_dad=portal&_schema=PORTAL'>Stadt Montreal</a> vom 14. Juli, 14:00 Uhr, liegen die meisten Indizes zwischen 16 und 37 und es handelt sich ebenfalls um Echtzeit-AQI.</p> <p>Können Sie mir den Unterschied erklären und welche Standarddetails Sie verwenden?</p> </blockquote> <p>Das ist in der Tat eine sehr gute Frage. und wir werden in diesem Artikel die verschiedenen verwendeten Skalen erklären, wie die Skalen miteinander verglichen werden und wie die Umrechnung durchgeführt werden kann.</p> <br><br> <center><br>oOo<br><br></center> <p>Wie wir in einem unserer <a href='faq/2015-03-20/a-comparison-of-worldwide-air-quality-scales-part-1/'>vorherigen Artikel</a> erklärt haben, basieren alle im Rahmen des World Air Quality Index-Projekts veröffentlichten AQI-Zahlen derzeit <sup><a href="#nowcast-footnote-1">[1]</a></sup> auf dem US-amerikanischen EPA-Standard. Weder Montreal noch Quebec unterliegen dieser Regel. Dies bestätigt, dass die auf der Seite <a href='/city/montreal/de/'>Stadt/Montreal</a> angezeigten Werte dem US-amerikanischen EPA-Standard entsprechen.</p> <p>Dies ist der Grund für den Unterschied zwischen den Messwerten des World Air Quality Index-Projekts und der Website der Stadt Montreal ( <a href='http://ville.montreal.qc.ca/portal/page?_pageid=7237,74495616&_dad=portal&_schema=PORTAL'>montreal.qc.ca</a> ): Die EPA (Environment Protection Agency) der Stadt Montreal verwendet ihre eigene richtige AQI-Skala, die auf klar beschrieben ist die gleiche Website. Um es etwas „komplexer“ zu machen, verwendet Quebec tatsächlich eine andere AQI-Skala ( <a href='http://www.iqa.mddefp.gouv.qc.ca/contenu/calcul.htm'>siehe diesen Link</a> ) im Vergleich zu Montreal (Tabarnac!). Und natürlich verwendet Kanada noch eine weitere Skala namens AQHI für den Air Quality Health Index – aber darüber haben wir bereits in einem anderen <a href='/faq/2015-06-03/overview-of-hong-kongs-air-quality-health-index'>Artikel</a> geschrieben.</p> <br> <p>Die Zusammenfassung der AQI-Haltepunkte von Montreal und Quebec ist in dieser Tabelle aufgeführt:</p> <center> <table class='fancy' style='width:90%;'> <tr style='background-color:#ccf;'> <th rowspan=2>Pollutant <th colspan=2 style='border-left:2px solid black;'>Quebec <th colspan=2 style='border-left:2px solid black;'>Montreal <tr style='background-color:#ccf;font-size:12px;'> <th style='border-left:2px solid black;'>Averaging Period <th>Reference Value <th style='border-left:2px solid black;'>Averaging Period <th>Reference Value <tr> <td>Fine Particles (PM<sub>2.5</sub>) <td style='border-left:2px solid black;'>3 hours <td>35µg/m3 <td style='border-left:2px solid black;'>3 hours <td>35µg/m3 <tr> <td>Ozone (O<sub>3</sub>) <td style='border-left:2px solid black;'>1 hour <td>82 ppb <td style='border-left:2px solid black;'>1 hour <td>160 µg/m3 <tr> <td>Nitrogen dioxide (NO<sub>2</sub>) <td style='border-left:2px solid black;'>1 hour <td>213 ppb <td style='border-left:2px solid black;'>1 hour <td>400 µg/m3 <tr> <td>Sulfur dioxide (SO<sub>2</sub>) <td style='border-left:2px solid black;'>4 minutes mobile <td>213 ppb <td style='border-left:2px solid black;'>10 minutes mobile <td>500 µg/m3 <tr> <td>Carbon monoxide (CO) <td style='border-left:2px solid black;'>1 hour <td>30 ppm <td style='border-left:2px solid black;'>1 hour <td>35 µg/m3 </table> </center> <br> <center><br>oOo<br><br></center> <p>Um die Werte auf den US-EPA-Standard umzurechnen, werden die Rohkonzentrationen ausgedrückt in Milligramm oder <a href='https://en.wikipedia.org/wiki/Parts-per_notation'>ppb/ppm</a> (Partikelanzahl pro Milliarde/Million) benötigt.</p> <p>Leider liefern weder Montreal noch der Landkreis Quebec diese Rohkonzentrationen. Stattdessen stellen sie nur die Luftqualitätswerte bereit, die bereits in ihre jeweiligen AQI-Skalen umgewandelt wurden. Dies stellt jedoch eigentlich kein Problem dar, da die Rückumrechnung in die Konzentration mit dieser einfachen linearen Formel erfolgen kann:</p> <center><code>Raw concentration (pollutant) = Reference value (pollutant) * AQI }(pollutant) / 50</code></center> <p>Wenn beispielsweise auf der Website der Stadt Montreal ein PM <sub>2,5-</sub> AQI-Wert von 18 veröffentlicht wird, beträgt die Rohkonzentration in Milligramm 18*35/50 = 12,6 mg/m3. Beachten Sie, dass die Einheit für Ozon, CO, SO <sub>2</sub> und NO <sub>2</sub> in Quebec und Montreal unterschiedlich ist (ppb für Quebec – US-Standard und mg für Montreal EU-Standard), aber das ist nur eine zusätzliche Umrechnung (teilweise in diesem <a href='/faq/2015-05-18/ground-ozone-air-quality-index-update-with-instant-cast'>Artikel</a> erklärt). .</p> <p>Beachten Sie, dass der PM <sub>2,5-</sub> AQI auf dem 3-Stunden-Durchschnitt basiert, während beim World Air Quality Index-Projekt die stündliche <a href='/faq/2015-03-15/air-quality-nowcast-a-beginners-guide/de/'>PM <sub>2,5</sub> Instant Cast</a> AQI-Berichterstattung verwendet wird. Da es nicht möglich ist, die stündlichen Daten aus dem 3-Stunden-Durchschnitt abzuleiten, bedeutet dies tatsächlich, dass der im Rahmen des World Air Quality Index-Projekts für Montreal und Quebec gemeldete PM <sub>2,5</sub> AQI nicht gerade eine „Instant Cast“-Berichterstattung ist.</p> <center><br>oOo<br><br></center> <p>Zum Abschluss folgt hier der visuelle Vergleich von drei AQI-Skalen (US EPA, Quebec und Montreal) für PM <sub>2,5</sub> und Ozon (beachten Sie, dass für Ozon die Einheit ppm verwendet wird – die Umrechnung von mg in ppm erfolgt also für Montreal). .</p> <p>Ein interessanter Punkt ist, dass sowohl Quebec als auch Montreal den AQI-Wert von 25 als Grenzwert zwischen „Gut“ (grün) und „Akzeptabel“ (gelb) verwenden, während dieser Grenzwert für die US-EPA bei 50 liegt. Alles in allem also Beim Vergleich von Apfel zu Apfel unter Berücksichtigung der richtigen Konvertierung und Haltepunkte ist der gemeldete AQI-Bereich zwischen dem US-amerikanischen EPA-Standard und den Quebec-/Montreal-Standards sehr ähnlich.</p> <table width=100% id='pm-table'> <tr> <div id='scale-pm25'></div> <div id='scale-o3'></div> </table> <script src="/jscripts/forecast/d3.v3.min.js"></script> <script src='/air/view/faq/images/aqi-scales/scales-viewer.min.js?_=1555547488'></script><link href='/air/view/faq/images/aqi-scales/scales-viewer.css?_=1555547488' rel='stylesheet'/> <script type="text/javascript"> function doInitPage() { var scales=new AqiScale({"montreal":{"standard":{"epa":"Ville de Montr\u00e9al","url":"http:\/\/ville.montreal.qc.ca\/portal\/page?_pageid=7237,74495616&_dad=portal&_schema=PORTAL","unit":["IQA","indice de la qualit\u00e9 de l\u2019air"]},"flag":"ca","levels":[{"range":25,"title":"Bon","color":"#78a22f","description":"-"},{"range":50,"title":"Aceptable","color":"#f5dd27","description":"-"},{"range":2000,"title":"Mauvais","color":"#ef4035","description":"-"}],"units":{"o3":"ug\/m3","no2":"ug\/m3","so2":"ug\/m3","co":"mg\/m3"},"pm25":[[25,17.5],[50,35],[100,70],[200,140],[300,210],[400,280],[500,350]],"o3":[[25,0.08],[50,0.16],[100,0.32],[200,0.74],[300,1.06]]},"quebec":{"standard":{"epa":"Minist\u00e8re du D\u00e9veloppement durable, de l\u2019Environnement et de la Lutte contre les changements climatiques","url":"http:\/\/www.iqa.mddefp.gouv.qc.ca\/contenu\/index.asp","unit":["IQA","indice de la qualit\u00e9 de l\u2019air"]},"flag":"ca","levels":[{"range":25,"title":"Bon","color":"#00ce00","description":"-"},{"range":50,"title":"Aceptable","color":"#ffff00","description":"-"},{"range":2000,"title":"Mauvais","color":"#ff0000","description":"-"}],"pm25":[[25,17.5],[50,35],[100,70],[200,140],[300,210],[400,280],[500,350]],"o3":[[25,0.041],[50,0.082],[100,0.164],[200,0.338],[300,0.502]]},"us":{"standard":{"epa":"United States Environmental Protection Agency","url":"http:\/\/epa.gov","unit":["AQI","Air Quality Index"]},"levels":[{"range":50,"title":"Good","color":"#009966","description":"Air quality is considered satisfactory, and air pollution poses little or no risk","textcolor":"#ffffff"},{"range":100,"title":"Moderate","color":"#ffde33","description":"Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution."},{"range":150,"title":"Unhealthy for Sensitive Groups","color":"#ff9933","description":"Members of sensitive groups may experience health effects.
