هوای تبریز برای تمامی گروه‌های سنی ناسالم شد

ایسنا/آذربایجان شرقی مدیر روابط عمومی اداره کل محیط زیست آذربایجان‌شرقی گفت: هوای تبریز برای تمامی گروه‌های سنی ناسالم شد.

داود قاسم زاده در گفت‌وگو با خبرنگاران، اظهار کرد: میانگین شاخص کیفیت هوای امروز تبریز برابر با ۱۵۳ بوده و برای همه گروه‌ها ناسالم است.

وی افزود: در وضعیتی که هوا برای همه گروه‌ها ناسالم است، توصیه می‌شود با مشارکت عمومی از هرگونه فعالیتی که منجر به افزایش آلودگی هوا می‌شود خودداری به عمل آید.

وی گفت: هم‌چنین افراد مبتلا به بیماری‌های قلبی یا ریوی، زنان باردار و شیرده، سالمندان و کودکان از فعالیت در خارج از منزل خودداری کنند.

قاسم زاده صرفه جویی در مصرف انرژی، پرهیز از ترددهای غیر ضروری درون شهری، مدیریت زمانی و مکانی سفرهای درون شهری و استفاده از حمل و نقل عمومی و عمل به توصیه‌های زیست محیطی را از راه‌های موثر در کاهش آلودگی هوا دانست.

بر اساس این گزارش؛ شاخص کیفی هوا (AQI) یا شاخص آلودگی هوا (PSI) معیاری است که غلظت ترکیبات مختلف آلاینده موجود در هوا نظیر منوکسید کربن، دی اکسیدگوگرد، ترکیبات نیتروژن‌دار، ازون و ذرات معلق (ذرات کوچک‌تر از ۱۰ میکرومتر و ذرات کوچک‌تر از ۲.۵ میکرومتر) را که دارای حدود مجاز متفاوت با واحدهای مختلف هستند، تبدیل به یک عدد بدون واحد کرده و وضعیت آلودگی هوا را سطوح مختلف نمایش می‌دهد.

بر اساس شاخص آلودگی هوا نیز این شاخص از صفر تا ۵۰ هوای پاک، ۵۱ تا ۱۰۰ هوای سالم، ۱۰۱ تا ۱۵۰ ناسالم برای گروه‌های حساس، ۱۵۱ تا ۲۰۰ ناسالم برای عموم، ۲۰۱ تا ۳۰۰ بسیار ناسالم، ۳۰۱ تا ۵۰۰ خطرناک است.
