Thanks. I was shocked at how it could be that high. That would mean people dropping dead left right and centre.
BTW, what is the greenery and nature like in and around Tehran? Is it like nice like Islamabad or a concrete Island like karachi?
Allow me inform you as someone who's lived there.
A key characteristic of Tehran is the abundance of parks, gardens, forest parks and natural features such as mountainside promenades or resorts, in keeping with the Iranian culture of gardening.
Gardens are part and parcel of the civilizational heritage of Iran. Of universal fame, the Persian garden has been added to UNESCO's world heritage list.

I would say Iranian garden culture is easily on par with, say, Japan's in terms of aesthetic depth and historical significance. Some of the subsisting Iranian gardens of old can be considered to rank among the finest anywhere, such as the Safavid era Bāq-e Fin in the city of Kāshān (Esfahān province).

This tradition is linked since ancient times to the sophisticated underground irrigation techniques which emerged on the Iranian plateau and allowed for the formation of lush, refreshing oases in the midst of arid land. The irrigation system in question - the Iranian qanāt, is another item on UNESCO's world heritage index by the way:

The term 'paradise' itself stems from an Old Iranian noun meaning walled enclosure. Iranian gardens traditionally have been surrounded by walls.

So the mentioned parks and greenery in Tehran represent one of the first things that impresses visitors arriving from countries like Iraq for instance. As far as orderliness and tidiness are concerned, I recall several Pakistani friends viewing relevant photographs in the Iranian section and finding Iranian cities to be clean.
A cursory glimpse into some of the parks and recreational areas in Tehran:

Indeed Iranian cities benefit from more than decent public services. This is also reflected in the development of public transportation. No less than six urban centers in Iran are equipped with metro networks, the capital being served by six inner city lines (with an average length of about 30 kilometers each) plus two suburban routes (of which one is an express commuter rail).
In short, for a city its size Tehran is pretty clean at the ground level and as far as edifices and construction works concerned, certainly not worse than a place like Paris (however, there's an issue with vacationing city folk leaving behind waste in the countryside, which is a habit that needs to be fixed).
Air pollution is a different matter though. Problem resides partly in the geography of Tehran, flanked as it is to its north and to a lesser extent to the east by quite elevated mountains which tend to block rain clouds and trap polluting substances above the city.
Another factor contributing to air pollution is Tehran's very high population density. To put things into perspective, the surface area of Tehran proper (without its suburbs nor the connected cities of the agglomeration), is 730 square kilometers housing nearly 9,5 million inhabitants. By contrast London stretches upon 1572 square kilometers while being populated by some 9 million souls. Tehran is therefore constructed twice as densely (knowing that the respective proportions of residential, non-residential and non-built up areas are comparable).
Add to it the fact that motor fuel is not always on par with latest environmental standards. And quite the amount of industrial factories are active in Tehran (some within administrative city limits and many nearby).
Nevertheless the figure in the OP does not seem realistic, I guess it is quite overblown in relation to the following entries.
