کاهش کیفیت هوا در مناطق پرتردد پایتخت طی امروز

بر اساس اعلام شرکت کنترل کیفیت هوای تهران، اگرچه صبح امروز (۲۷ آبان ماه) کیفیت هوا در شرایط قابل قبول است اما با حاکمیت جو نسبتاً پایدار و آرام تا اواخر وقت همزمان با افزایش ترافیک، کاهش کیفیت هوا در مناطق پرتردد انتظار می‌رود.

به گزارش ایسنا، پیش‌ بینی‌های انجام‌شده در شرکت کنترل کیفیت هوای شهر تهران حاکی از آن است که در صبحگاه امروز(۲۷ آبان ماه) در بیشتر مناطق کیفیت هوا در محدوده‌ قابل‌ قبول قرار خواهد گرفت که ناشی از ناپایداری جوی طی ساعات گذشته و برقراری شرایط مساعد جهت پراکندگی آلاینده‌ها است.

با عدم وزش باد مؤثر در طول روز پراکندگی آلاینده‌ها محدود خواهد شد. با حاکمیت جو نسبتاً پایدار و آرام تا اواخر وقت پنجشنبه (۲۷ آبان ماه) همزمان با افزایش ترافیک به‌تدریج بر غلظت ذرات معلق افزوده خواهد شد که کاهش کیفیت هوا در مناطق پرتردد را به‌دنبال خواهد داشت.

با تداوم این شرایط جوی تا صبح روز جمعه (۲۸ آبان ماه) باوجود کاهش تردد خودروها در روز تعطیل برقراری وضعیت ناسالم برای گروه‌های حساس در برخی مناطق دور از انتظار نخواهد بود. عدم وزش باد مؤثر در طول روز از پراکندگی آلاینده‌ها جلوگیری خواهد کرد. با تداوم پایداری و سکون جو تا ساعات پایانی جمعه همراه با ترافیک شامگاهی برقراری وضعیت ناسالم برای گروه‌های حساس در برخی مناطق پرتردد پیش‌بینی می‌شود.

به گزارش ایسنا، آلاینده شاخص هوای پایتخت طی ۲۴ ساعت گذشته «ذرات معلق کمتر از ۲.۵میکرون» با میانگین ۷۳ بود و کیفیت هوای پایتخت در وضعیت قابل قبول قرار داشت. آلاینده شاخص هم‌اکنون «ذرات معلق کمتر از ۲.۵میکرون» با میانگین ۶۸ و کیفیت هوا در وضعیت قابل قبول است.
