Iranians were issued a smog warning for this week, starting their Monday off by being told to stay indoors or don face masks if they venture outdoors. Tehran is known for many things — a vibrant city full of culture, life, the capital of the nation and the third biggest metropolitan city in the Middle East (after Cairo and Istanbul). But one thing that has uniquely set it apart from its neighbouring metropolises is its persistent smog. In recent years the problem has escalated. In December 2015, Tehran was put under an unprecedented warning that contaminants in the air were seven times the maximum level recommended by the World Health Organization (WHO). The record high of last year was not reached, but on 13 November, 2016 similar warnings were issued for contaminants being three times over the the WHO recommendation. Schools were shut down on Monday and continue to be closed into the week, as ordered by the Ministry of Education. Residents were warned not to go out unless absolutely necessary, with particular warnings to remain indoors for the elderly, children, pregnant and those with respiratory problems. The pressure is expected to lift on Wednesday when a wind us expected to push through the stagnant and polluted air. Smog becomes a matter of national concern every year as the weather cools. Cold weather traps the high levels of exhaust within the city, fuelled by the millions of ageing cars and motorbikes in a city of 10 million residents. The issue has become a political talking point, especially as hardliners blame the moderate administration of Hassan Rouhani for failing at their environmental policy. It's no surprise that the hardline Javan newspaper ran a headline on Monday claiming “the peaceful death of citizens in the polluted air.” Their front page article referenced a 2014-2015 study that claimed 5,158 residents of Tehran had lost their lives owing to respiratory problems caused by the pollution. It appears that this week, many of the residents of Tehran are continuing about their daily activities as per usual, although many with face masks or with efforts to use the cities developing metro system.

One reoccurring image that has been springing up on Iranian Instagram and Telegram accounts is Tehran's iconic Milad Tower, either engulfed by the smog or wearing a face mask to deal with the smog. Below are some samples of various Tehran based Instagram users depicting versions of the tower amidst the city's smog. In the first, the tower screams out “komak,” Persian for “help,” as it's surrounded by polluted air: بدون شرح #آلودگی_هوا#تهران#برج_میلاد#آلودگی_هوای_تهران#غلظت#دود 🔻 #ایران#ایران_من#ساخت_ایران#زنده_باد_ایران_و_ایرانی#پاینده_باد_ایران_ایرانی#ایران_من#کار#شغل#اشتغال#آینده#آینده_شغلی#دولت#مسئولین#made_in_iran#made_in_iran_98# A photo posted by made_in_iran🇮🇷ساخت_ایران (@made_in_iran98) on Without explanation #air_pollution #Tehran #Milad_Tower #air_pollution_Tehran #density #smog_Iran #my_iran #iran_creation #long_live_iran_and_iranians #lasting_wind_iran_irania #my_iran #work #profession #occupation #future_profession #made_in_iran #made_in_iran_98 #velt #officials In the second post, a user uses the occasion of smog to make a romantic sonnet for a lover who has left, only to leave smog behind in her absence: ؁ تا تو تهران را ترک کردی آلوده شد – به دود، به نبود – برگرد حال ما را خوب کن . #امید_دیوسالار . . #امیددیوسالار #دود #دل #قلب #راه #هوای_خوب #دیوسالار #شعر #ماسک #ادبیات #تایپوگرافی #تایپوگرافی_فارسی #typography #تهران #برج_میلاد #Design #illustration #photography #photo #هوای_آلوده #هوای_پاک #شعرسپید #عاشقانه #غزل #برگرد #iloveyou #illustrator #فتوشاپ A photo posted by امید دیوسالار ﴿شعر و گرافیک﴾ (@omiddivsalar) on Just when you left Tehran the pollution started — towards smog, towards absence — come back and make us better. #hope_divsalar #hope_forSalar #smog #heart #Tehran #milad_Tower #typography #heart #way #good_weather #divsalar #poetry #mask #literature #typography #farsi_typogaphy #iloveyou #polluted_weather #white_poetry #romantic #sonnet #comeback #photo #photography #illustration #design #photoshop #illustrator The last photo, a cartoon of the tower with Tehranis blindly reaching up towards it, is posted with a somber caption describing the poisoning of the city's population: #پست_موقت . . #تصویر_نوشت . آمدم بیرون فقط در آسـمان‌ها #دود بود در هـوای شهر من تنها هوا کمبود بود . . . . . #دود_نوشت . حاشا به #دود و گرد و غبار آنکه حل شود #تهران برای مردم دنیا مثل شود . . . . . #طنز_نوشت .
