آلودگی هوای تهران «در مرز هشدار»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. > دیگر عکسهای خبرگزاری مهر از آلودگی امروز هوای تهران را ببینید 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. |
