کیفیت هوای پایتخت در محدوده قابل قبول

بنابر اعلام شرکت کنترل کیفیت هوای تهران، کیفیت هوا در بیشتر مناطق در محدوده قابل‌قبول است.

به گزارش ایسنا، براساس پیش‌بینی‌های انجام‌شده در شرکت کنترل کیفیت هوا، در صبح روز جمعه (۱۵مرداد ۱۴۰۰) در بیشتر مناطق کیفیت هوا در محدوده قابل‌قبول است که ناشی از کاهش تردد خودروها در روز تعطیل و همچنین حاکمیت جو ناپایدار و پراکندگی آلاینده‌ها طی ساعات گذشته است.
با عدم وزش باد مؤثر در طول روز پراکندگی آلاینده‌ها محدود خواهد شد، حضور عوامل کافی در برخی ساعات بعدازظهر نیز سبب تولید آلاینده ازن خواهد شد که به‌تبع آن برقراری وضعیت ناسالم برای گروه‌های حساس در برخی مناطق دور از انتظار نخواهد بود. تا اواخر وقت جممه به‌تدریج بر تندی باد افزوده خواهد شد و بنابراین کیفیت هوا در بیشتر مناطق در محدوده قابل‌قبول قرار خواهد گرفت.
کاهش تندی باد تا صبح روز شنبه (۱۶ مرداد ۱۴۰۰) همراه با آغاز تردد خودروها در نخستین روز هفته شرایط مناسب جهت تجمع آلاینده‌ها را فراهم خواهد کرد و کیفیت هوا در مناطق پرتردد در محدوده ناسالم برای گروه‌های حساس قرار خواهد گرفت. افزایش تندی باد در طی روز سبب پراکندگی آلاینده‌ها خواهد شد، بااین حال با افزایش دما احتمال کاهش کیفیت هوا به دلیل تولید و افزایش غلظت آلاینده ازن وجود خواهد داشت. با تداوم وزش باد مؤثر تا ساعات پایانی شنبه کاهش غلظت ذرات معلق و برقراری وضعیت قابل‌قبول در بیشتر مناطق پیش‌بینی می‌شود.
به گزارش ایسنا، آلاینده شاخص هوای پایتخت طی ۲۴ ساعت گذشته «ازن» با میانگین ۱۱۵ بود و هوای پایتخت در وضعیت ناسالم برای گروه‌های حساس قرار داشت. آلاینده شاخص هم‌اکنون «ذرات معلق کمتر از ۲.۵ میکرون» با میانگین ۷۸ است‌ و کیفیت هوا در محدوده قابل قبول است.
