هوای ناسالم تهران برای گروه‌های حساس
عکس خبر آرشیوی است.

بر اساس اعلام شرکت کنترل کیفیت هوای شهر تهران، هم اکنون، دوشنبه (۵ مهر ۱۴۰۰) باوجود کاهش تردد خودروها در روز تعطیل، کیفیت هوا در بیشتر مناطق در محدوده ناسالم برای گروه‌های حساس قرار دارد.

 پیش‌بینی‌های انجام‌شده در شرکت کنترل کیفیت هوای شهر تهران نشان می‌دهد که در صبح روز دوشنبه (۵ مهر ۱۴۰۰) باوجود کاهش تردد خودروها در روز تعطیل، کیفیت هوا در بیشتر مناطق در محدوده ناسالم برای گروه‌های حساس قرار خواهد گرفت که ناشی از عدم وزش باد مؤثر و انباشت آلاینده‌ها طی ساعات گذشته است.
همچنین کاهش تندی باد در طول روز پراکندگی آلاینده‌ها را محدود خواهد کرد. با تداوم این شرایط جوی تا اواخر وقت دوشنبه همراه با افزایش ترافیک شامگاهی کیفیت هوا در مناطق پرتردد در وضعیت ناسالم برای گروه‌های حساس قرار خواهد گرفت.
در این گزارش آمده است که با وزش باد مؤثر تا صبح روز سه‌شنبه (۶ مهر ۱۴۰۰) انتظار می‌رود کیفیت هوا در محدوده قابل‌قبول قرار گیرد، اگرچه با آغاز تردد خودروها احتمال کاهش کیفیت هوا در پاره‌ای از مناطق پرتردد وجود خواهد داشت. افزایش نسبی تندی باد در طول روز پراکندگی آلاینده‌ها را تسهیل خواهد کرد. به‌تدریج با کاهش تندی باد تا اواخر وقت سه‌شنبه هم‌زمان با افزایش تردد خودروها، افزایش غلظت ذرات معلق و بنابراین کاهش کیفیت هوا در برخی مناطق پایتخت پیش‌بینی می‌شود.
آلاینده شاخص هوای پایتخت طی ۲۴ ساعت گذشته ذرات معلق کمتر از ۱۰ میکرون با میانگین ۱۲۹ بود و کیفیت هوای پایتخت در وضعیت ناسالم برای گروه‌های حساس قرار داشت. آلاینده شاخص هم‌اکنون ذرات معلق کمتر از ۲.۵ میکرون با میانگین ۱۰۴ و کیفیت هوا در وضعیت ناسالم برای گروه‌های حساس است.
