Quebec.<br> (attribution: <a href='https://en.wikipedia.org/wiki/Flag_of_Quebec'>wikipedia</a>) </small> </div> <p class="bigletter">Τα δεδομένα ποιότητας αέρα για <a href='/city/montreal/el/'>το Μόντρεαλ</a> και <a href='/map/quebec/el/'>το Κεμπέκ</a> ήταν διαθέσιμα εδώ και λίγο καιρό, αλλά πρόσφατα λάβαμε λίγες ερωτήσεις σχετικά με την κλίμακα AQI που χρησιμοποιείται σε αυτό το τμήμα του Καναδά. Ένας από αυτούς είναι από τη Marie A., η οποία ρώτησε:</p> <blockquote> <p>Θα ήθελα να μάθω γιατί ο δείκτης ποιότητας αέρα στον ιστότοπό σας είναι διαφορετικός από το AQI στον ιστότοπο του Μόντρεαλ; Υπολογίζετε ξανά κάτι για να πληροίτε τα πρότυπα AQI EPA των ΗΠΑ; Αν ναι, πώς; Με τι δεδομένα;</p> <p>Για παράδειγμα, ημερομηνία 14 Ιουλίου 2:00 μ.μ., τα περισσότερα ευρετήρια στον <a href='/city/montreal/el/'>ιστότοπό</a> σας κυμαίνονται από 53 έως 65 (ένας δείκτης είναι 37) και υποτίθεται ότι είναι AQI σε πραγματικό χρόνο. Στον ιστότοπο της <a href='http://ville.montreal.qc.ca/portal/page?_pageid=7237,74495616&_dad=portal&_schema=PORTAL'>πόλης του Μόντρεαλ</a> , ημερομηνία 14 Ιουλίου 2:00 μ.μ., οι περισσότεροι δείκτες κυμαίνονται από 16 έως 37 και είναι επίσης AQI σε πραγματικό χρόνο.</p> <p>Λοιπόν, μπορείτε να μου εξηγήσετε τη διαφορά και ποιες λεπτομέρειες στα πρότυπα χρησιμοποιείτε;</p> </blockquote> <p>Αυτή είναι πράγματι μια πολύ καλή ερώτηση. και θα εξηγήσουμε σε αυτό το άρθρο τις διαφορετικές κλίμακες που χρησιμοποιούνται, πώς συγκρίνονται οι ζυγαριές μεταξύ τους και πώς μπορεί να γίνει η μετατροπή.</p> <br><br> <center><br>oOo<br><br></center> <p>Όπως εξηγήσαμε σε ένα από τα <a href='faq/2015-03-20/a-comparison-of-worldwide-air-quality-scales-part-1/'>προηγούμενα άρθρα</a> μας , όλα τα στοιχεία AQI που δημοσιεύτηκαν στο έργο World Air Quality Index <sup><a href="#nowcast-footnote-1">[1]</a></sup> χρησιμοποιούν αυτήν τη στιγμή το πρότυπο EPA των ΗΠΑ. Ούτε το Μόντρεαλ ούτε το Κεμπέκ αναμένουν αυτόν τον κανόνα, επομένως αυτό επιβεβαιώνει ότι οι τιμές που εμφανίζονται στη σελίδα <a href='/city/montreal/el/'>πόλη/μόντρεαλ</a> χρησιμοποιούν το πρότυπο EPA των ΗΠΑ.</p> <p>Αυτός είναι ο λόγος για τη διαφορά μεταξύ των αναγνώσεων του έργου World Air Quality Index και του ιστότοπου της πόλης του Μόντρεαλ ( <a href='http://ville.montreal.qc.ca/portal/page?_pageid=7237,74495616&_dad=portal&_schema=PORTAL'>montreal.qc.ca</a> ): Η EPA της πόλης του Μόντρεαλ (Υπηρεσία Προστασίας Περιβάλλοντος) χρησιμοποιεί τη δική της κατάλληλη κλίμακα AQI, η οποία περιγράφεται με σαφήνεια στο την ίδια ιστοσελίδα. Για να το κάνει λίγο πιο «σύνθετο», το Κεμπέκ χρησιμοποιεί στην πραγματικότητα μια άλλη κλίμακα AQI ( <a href='http://www.iqa.mddefp.gouv.qc.ca/contenu/calcul.htm'>που καθορίζεται σε αυτόν τον σύνδεσμο</a> ) σε σύγκριση με το Μόντρεαλ (ταμπαρνάκ!). Και φυσικά, ο Καναδάς χρησιμοποιεί μια άλλη κλίμακα, που ονομάζεται AQHI for Air Quality Health Index - αλλά αυτό είναι κάτι για το οποίο έχουμε ήδη γράψει σε άλλο <a href='/faq/2015-06-03/overview-of-hong-kongs-air-quality-health-index'>άρθρο</a> .</p> <br> <p>Η περίληψη των σημείων διακοπής AQI του Μόντρεαλ και του Κεμπέκ παρατίθεται σε αυτόν τον πίνακα:</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>Για να μετατραπούν οι τιμές στο πρότυπο EPA των ΗΠΑ, απαιτούνται οι ακατέργαστες συγκεντρώσεις που εκφράζονται σε χιλιοστόγραμμα ή <a href='https://en.wikipedia.org/wiki/Parts-per_notation'>ppb/ppm</a> (αριθμός σωματιδίων ανά δισεκατομμύριο/εκατομμύριο).</p> <p>Δυστυχώς, ούτε το Μόντρεαλ ούτε η κομητεία του Κεμπέκ παρέχουν αυτές τις ακατέργαστες συγκεντρώσεις. Αντίθετα, παρέχουν μόνο τις ενδείξεις ποιότητας αέρα που έχουν ήδη μετατραπεί στις δικές τους αντίστοιχες κλίμακες AQI. Αλλά αυτό στην πραγματικότητα δεν είναι πρόβλημα, καθώς η εκ νέου μετατροπή σε συγκέντρωση μπορεί να γίνει χρησιμοποιώντας αυτόν τον απλό γραμμικό τύπο:</p> <center><code>Raw concentration (pollutant) = Reference value (pollutant) * AQI }(pollutant) / 50</code></center> <p>Για παράδειγμα, εάν μια τιμή PM <sub>2,5</sub> AQI 18 δημοσιεύεται στον ιστότοπο της πόλης του Μόντρεαλ, τότε η ακατέργαστη συγκέντρωση σε χιλιοστόγραμμα είναι 18*35/50 = 12,6 mg/m3. Σημειώστε ότι για το Όζον, το CO, το SO <sub>2</sub> και το NO <sub>2</sub> η μονάδα είναι διαφορετική για το Κεμπέκ και το Μόντρεαλ (ppb για το Κεμπέκ - πρότυπο ΗΠΑ και mg για το πρότυπο ΕΕ του Μόντρεαλ), αλλά αυτή είναι απλώς μια πρόσθετη μετατροπή (εξηγείται εν μέρει σε αυτό <a href='/faq/2015-05-18/ground-ozone-air-quality-index-update-with-instant-cast'>το άρθρο</a> ) .</p> <p>Σημειώστε ότι το PM <sub>2.5</sub> AQI βασίζεται σε μέσο όρο 3 ωρών, ενώ στο έργο World Air Quality Index, χρησιμοποιείται η ωριαία αναφορά <a href='/faq/2015-03-15/air-quality-nowcast-a-beginners-guide/el/'>PM <sub>2.5</sub> Instant Cast</a> AQI. Δεδομένου ότι δεν είναι δυνατό να αφαιρεθούν τα ωριαία δεδομένα από τον μέσο όρο των 3 ωρών, αυτό σημαίνει στην πραγματικότητα ότι το PM <sub>2.5</sub> AQI που αναφέρεται στο έργο World Air Quality Index για το Μόντρεαλ και το Κεμπέκ δεν είναι ακριβώς μια αναφορά "Instant Cast".</p> <center><br>oOo<br><br></center> <p>Λοιπόν, τελευταίο, εδώ είναι η οπτική σύγκριση 3 κλιμάκων AQI (US EPA, Κεμπέκ και Μόντρεαλ) για PM <sub>2,5</sub> και Όζον (σημειώστε ότι για το Όζον χρησιμοποιείται η μονάδα ppm - επομένως η μετατροπή από mg σε ppm γίνεται για το Μόντρεαλ) .</p> <p>Ένα ενδιαφέρον σημείο που πρέπει να παρατηρήσετε είναι ότι τόσο το Κεμπέκ όσο και το Μόντρεαλ χρησιμοποιούν την τιμή AQI του 25 ως σημείο διακοπής μεταξύ Καλό (πράσινο) και Αποδεκτό (κίτρινο), ενώ για την EPA των ΗΠΑ, αυτό το σημείο διακοπής ορίζεται στο 50. Άρα, συνολικά , όταν συγκρίνετε apple-to-apple έχοντας κατά νου τη σωστή μετατροπή και σημεία διακοπής, το αναφερόμενο εύρος AQI είναι πολύ παρόμοιο μεταξύ του προτύπου EPA των ΗΠΑ και των προτύπων Κεμπέκ/Μόντρεαλ.</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.
