تداوم هوای ناسالم برای گروه‌های حساس در پایتخت

براساس اعلام شرکت کنترل کیفیت هوای ‌پایتخت، کیفیت هوای ‌پایتخت طی ۲۴ ساعت گذشته و هم‌اکنون (۲۶ اسفند ماه) در محدوده ناسالم برای گروه‌های حساس قرار داشته است اما وزش باد موثر طی روز بهبود کیفیت هوا در بیشتر مناطق ‌پایتخت را به‌همراه خواهد داشت.

به گزارش ایسنا، پیش‌بینی‌های انجام‌شده در شرکت کنترل کیفیت هوای شهر تهران حاکی از آن است که در صبحگاه امروز (۲۶ اسفند ماه) کیفیت هوا در بیشتر مناطق در محدوده ناسالم و ناسالم برای گروه‌های حساس قرار خواهد گرفت که ناشی از پایداری جوی، عدم وزش باد مؤثر و انباشت آلاینده‌ها طی ساعات گذشته همراه با افزایش حجم ترافیک صبحگاهی است.

به‌تدریج با رشد ناپایداری جوی طی روز و احتمال وقوع رگبار پراکنده در برخی ساعات بعدازظهر بر تندی باد افزوده می‌شود و شرایط مناسب جهت پراکندگی آلاینده‌ها فراهم خواهد شد. این شرایط مساعد جوی تا اواخر وقت ادامه خواهد داشت و باوجود افزایش ترافیک شامگاهی در بیشتر مناطق پایتخت برقراری وضعیت قابل‌قبول را به دنبال خواهد داشت.

صبح فردا (۲۷ اسفند ماه) در بیشتر مناطق کیفیت هوا در محدوده قابل‌قبول قرار خواهد گرفت، هرچند با افزایش ترافیک افزایش غلظت آلاینده‌ها در مناطق پرتردد دور از انتظار نخواهد بود. وزش باد مؤثر طی روز پراکندگی آلاینده‌ها را تسهیل خواهد کرد و در شامگاه فردا (۲۷ اسفند ماه)  نیز با برقراری شرایط مساعد جوی پیش‌بینی می‌شود که در بیشتر مناطق کیفیت هوا در محدوده قابل‌قبول قرار خواهد گرفت.

به گزارش ایسنا، آلاینده شاخص هوای پایتخت طی ۲۴ ساعت گذشته «ذرات معلق کمتر از ۲.۵ میکرون» با میانگین ۱۴۱ بود و هوای پایتخت در شرایط ‌ناسالم برای گروه‌های حساس قرار داشت. آلاینده شاخص هم‌اکنون «ذرات معلق کمتر از ۲.۵ میکرون» با میانگین  ۱۳۲ است و هوا در محدوده ناسالم برای گروه‌های حساس قرار دارد.
