آلودگی هوای تهران «در مرز هشدار»

تهران نفس نمی‌کشد (مهر)

این عکس‌ها هولناک هستند. باور کردنی نیست؛ اما حقیقت دارد.

پدیده‌ی «وارونگی» (Inversion) مهمان همیشگی پاییزهای تهران است و اهالی این شهر را به ضیافت آلودگی هوا می‌برد.

آن قدر پاییز و زمستان‌های آلوده آمده‌اند و رفته‌اند که دیگر نام «وارونگی» برای ساکنان تهران و چندین شهر بزرگ دیگر این مرز و بوم ناآشنا نیست. قرار گرفتن هوای سرد در لایه‌های پایین جوی و هوای گرم در لایه‌های بالایی، به همراه نوزیدن باد، مانع از تهویه هوای شهر می‌شود و آلاینده‌ها همین طور روی هم تلنبار می‌شود تا جایی که دیگر هوایی برای انسان‌ها نماند.

هر چند که چند سالی است که دیگر خبری از سرب در بنزین و بالطبع هوای تهران نیست، اما امروز میزان آلودگی هوا در تهران، بار دیگر به مرز «هشدار» رسید. هر چند که هنوز به مرز «اضطرار» نرسیده است تا مدارس تعطیل شوند و محدوده طرح ترافیک گسترش یابد و کسی واقعاً کاری انجام دهد.

امروز واقعاً نفس کشیدن در هوای تهران، سخت و دشوار بود. باید به این امید بنشینیم که باد یا بارانی بیاید و نفس شهر را باز کند.
