هوای مطلوب پایتخت طی امروز

بر اساس اعلام شرکت کنترل کیفیت هوای تهران، هوای پایتخت در حال حاضر در شرایط کیفی قابل قبول قرار دارد.

به گزارش ایسنا، کیفیت هوای پایتخت در حال حاضر با میانگین ۸۰ در شرایط قابل قبول (سالم) است. کیفیت هوای ۲۴ ساعت گذشته نیز با میانگین ۵۸ در شرایط قابل قبول (سالم) قرار داشت.

بر اساس این گزارش شاخص کیفیت هوا (AQI) به پنج دسته اصلی تقسیم‌بندی می‌شود. بر اساس این تقسیم‌بندی از عدد صفر تا ۵۰ هوا پاک، از ۵۱ تا ۱۰۰ هوا قابل قبول یا متوسط، از ۱۰۱ تا ۱۵۰ هوا ناسالم برای گروه‌های حساس، از ۱۵۱ تا ۲۰۰ هوا ناسالم برای همه گروه‌ها، از ۲۰۱ تا ۳۰۰ هوا بسیار ناسالم و از ۳۰۱ تا ۵۰۰ شرایط کیفی هوا خطرناک است.

گفتنی است در هوای پاک که با رنگ سبز نشان داده می‌شود، شرایط کیفیت هوا مناسب است و خطری برای سلامت انسان ندارد. در هوای قابل قبول که به رنگ زرد شناخته می‌شود، کیفیت هوا قابل قبول و غلظت آلاینده‌ها کمتر از حدی است که بر سلامت انسان تاثیر منفی داشته باشد اما در هوای ناسالم برای گروه‌های حساس که به رنگ نارنجی نشانه‌گذاری می‌شود، مقدار AQI بین ۱۰۱ تا ۱۵۰ قرار می‌گیرد که در نتیجه آن گروه‌های حساس اثرپذیری بیشتری از آلودگی هوا خواهند داشت.

در هوای ناسالم که به رنگ قرمز است، کلیه افراد جامعه در معرض مخاطرات ناشی از آلودگی هوا قرار می‌گیرند و حتی ممکن است گروه‌های حساس دچار عوارض شدیدتری شوند. افزون بر این در هوای بسیار ناسالم که به رنگ بنفش نشان داده می‌شود و عدد AQI بین ۲۰۱ تا ۳۰۰ قرار می‌گیرد، احتمال بروز عوارض جدی برای سلامت افراد جامعه افزایش می‌یابد.
