<a href='/map/quebec/fa/'>کبک</a> برای مدتی در دسترس بوده است، اما اخیراً سؤالات کمی در مورد مقیاس AQI مورد استفاده در این بخش از کانادا دریافت کردیم. یکی از آنها از Marie A. است که پرسید:</p> <blockquote> <p>من می خواهم بدانم چرا شاخص کیفیت هوا در وب سایت شما با AQI در وب سایت مونترال متفاوت است؟ آیا چیزی را برای مطابقت با استانداردهای EPA AQI ایالات متحده دوباره محاسبه می کنید؟ اگر چنین است، چگونه؟ با چه داده ای؟</p> <p>به عنوان مثال، تاریخ 14 جولای ساعت 2:00 بعد از ظهر، بیشتر ایندکس ها در <a href='/city/montreal/fa/'>وب سایت</a> شما از 53 تا 65 متغیر است (یک شاخص 37 است) و قرار است AQI بیدرنگ باشد. در وب سایت <a href='http://ville.montreal.qc.ca/portal/page?_pageid=7237,74495616&_dad=portal&_schema=PORTAL'>شهر مونترال</a> ، تاریخ 14 ژوئیه ساعت 2:00 بعد از ظهر، بیشتر شاخص ها از 16 تا 37 متغیر است و همچنین AQI بلادرنگ است.</p> <p>بنابراین، می توانید تفاوت را برای من توضیح دهید و از چه جزئیات استانداردهایی استفاده می کنید؟</p> </blockquote> <p>این واقعاً سؤال بسیار خوبی است. و در این مقاله ترازوهای مختلف مورد استفاده، نحوه مقایسه ترازوها با یکدیگر و نحوه تبدیل را توضیح خواهیم داد.</p> <br><br> <center><br>oOo<br><br></center> <p>همانطور که در یکی از <a href='faq/2015-03-20/a-comparison-of-worldwide-air-quality-scales-part-1/'>مقالات قبلی</a> خود توضیح دادیم، تمام ارقام AQI منتشر شده در پروژه شاخص کیفیت هوای جهانی در حال حاضر <sup><a href="#nowcast-footnote-1">[1]</a></sup> از استاندارد EPA ایالات متحده استفاده می کنند. نه مونترال و نه کبک انتظار این قانون را ندارند، بنابراین این تأیید می کند که مقادیر نمایش داده شده در صفحه <a href='/city/montreal/fa/'>شهر/مونترال</a> از استاندارد EPA ایالات متحده استفاده می کنند.</p> <p>دلیل تفاوت بین خوانش‌های پروژه شاخص کیفیت هوای جهانی و وب‌سایت شهر مونترال ( <a href='http://ville.montreal.qc.ca/portal/page?_pageid=7237,74495616&_dad=portal&_schema=PORTAL'>montreal.qc.ca</a> ) به همین دلیل است: EPA شهر مونترال (آژانس حفاظت از محیط زیست) از مقیاس AQI مناسب خود استفاده می‌کند که به وضوح در توضیح داده شده است. همان وب سایت برای اینکه آن را کمی «پیچیده‌تر» کند، کبک در واقع از مقیاس AQI دیگری ( <a href='http://www.iqa.mddefp.gouv.qc.ca/contenu/calcul.htm'>که در این پیوند مشخص شده است</a> ) در مقایسه با مونترال (تابرناک!) استفاده می‌کند. و البته، کانادا از مقیاس دیگری به نام AQHI برای شاخص سلامت کیفیت هوا استفاده می‌کند - اما این چیزی است که قبلاً در <a href='/faq/2015-06-03/overview-of-hong-kongs-air-quality-health-index'>مقاله</a> دیگری درباره آن نوشتیم.</p> <br> <p>خلاصه نقاط شکست مونترال و کبک AQI در این جدول آمده است:</p> <center> <table

میلی گرم یا <a href='https://en.wikipedia.org/wiki/Parts-per_notation'>ppb/ppm</a> (تعداد ذرات در هر میلیارد در میلیون) مورد نیاز است.</p> <p>متأسفانه، نه مونترال و نه شهرستان کبک این غلظت های خام را ارائه نمی کنند. در عوض آنها فقط خوانش‌های کیفیت هوا را ارائه می‌کنند که قبلاً به مقیاس‌های AQI مربوطه خود تبدیل شده‌اند. اما این در واقع مشکلی نیست، زیرا تبدیل مجدد به غلظت را می توان با استفاده از این فرمول خطی ساده انجام داد:</p> <center><code>Raw concentration (pollutant) = Reference value (pollutant) * AQI }(pollutant) / 50</code></center> <p>به عنوان مثال، اگر مقدار PM <sub>2.5</sub> AQI 18 در وب سایت شهر مونترال منتشر شود، غلظت خام بر حسب میلی گرم 18*35/50 = 12.6 میلی گرم بر متر مکعب است. توجه داشته باشید که برای ازن، CO، SO <sub>2</sub> و NO <sub>2</sub> واحد برای کبک و مونترال متفاوت است (ppb برای کبک - استاندارد ایالات متحده، و mg برای استاندارد اتحادیه اروپا مونترال)، اما این فقط یک تبدیل اضافی است (تا حدی در این <a href='/faq/2015-05-18/ground-ozone-air-quality-index-update-with-instant-cast'>مقاله</a> توضیح داده شده است). .</p> <p>توجه داشته باشید که PM <sub>2.5</sub> AQI بر اساس میانگین 3 ساعته است، در حالی که در پروژه جهانی کیفیت هوا، از گزارش ساعتی <a href='/faq/2015-03-15/air-quality-nowcast-a-beginners-guide/fa/'>PM <sub>2.5</sub> Instant Cast</a> AQI استفاده می شود. از آنجایی که نمی توان داده های ساعتی را از میانگین 3 ساعت کسر کرد، این در واقع به این معنی است که PM <sub>2.5</sub> AQI گزارش شده در پروژه شاخص کیفیت هوای جهانی برای مونترال و کبک دقیقاً یک گزارش "بازیگر فوری" نیست.</p> <center><br>oOo<br><br></center> <p>بنابراین، در آخر، در اینجا مقایسه بصری 3 مقیاس AQI (US EPA، کبک و مونترال) برای PM <sub>2.5</sub> و ازن است (توجه داشته باشید که برای ازن، واحد ppm استفاده می شود - بنابراین تبدیل از mg به ppm برای مونترال انجام می شود). .</p> <p>نکته جالب توجه این است که هم کبک و هم مونترال از مقدار AQI 25 به عنوان نقطه شکست بین خوب (سبز) و قابل قبول (زرد) استفاده می کنند، در حالی که برای EPA ایالات متحده، این نقطه شکست 50 تعیین شده است. بنابراین، در مجموع، ، هنگام مقایسه سیب به سیب با تبدیل مناسب و نقاط شکست در ذهن، محدوده AQI گزارش شده بین استاندارد EPA ایالات متحده و استانداردهای کبک/مونترال بسیار مشابه است.</p> <table width=100% id='pm-table'> <tr> <div id='scale-pm25'></div> <div id='scale-o3'></div> </table> <script
