Etymology

There are various theories pertaining to the origin of the name Tehran. One plausible theory is that the word 'Tehran' is derived from Tiran/Tirgan, "The Abode of Tir" . The ancient Parthia Parthia

Parthia was a civilization situated in the northeast of modern Iran, but at its height covering all of ... 

n town of Tiran was a neighbor to the town of Mehran . Both of these were mere villages in the suburbs of the great city of Ray/Rhages Ray, Iran

[i]
... 

. Mehran is still extant and forms a residential district inside the Greater Tehran, as is also Ray Ray, Iran

[i]
... 

--which forms the southern suburbs of Tehran.

Another theory is that Tehran means "a warm place", as opposed to "a cool place" - a cooler district in northern Tehran. Some current texts in this regard claim that the word Tehran in Persian means "warm mountain slope" .

The official City of Tehran website says that “Tehran” comes from the Persians words "Tah" meaning "end or bottom" and "Ran" meaning “[mountain] slope" - literally, bottom of the mountain slope. Given Tehran's geographic position at the bottom of the slope of the Alborz Mountains, this appears to be the most plausible explanation of the origin of the name of the city .

Economy

About 30% of Iran’s public-sector workforce and 45% of large industrial firms are located in Tehran and almost half of these workers work for the government. Most of the remainder of workers are factory workers, shopkeepers, labourers, and transport workers. Few foreign companies operate in Tehran because of the Islamic government and its poor relations with the west. But before the Islamic revolution Iranian Revolution

 many western companies were active in this region. Today many modern industries of this city include the manufacturing of automobiles, electronics and electrical equipment, weaponry, textiles, sugar, cement, and chemical products. It is also a leading center for the sale of carpets and furniture. There is an oil refinery nearby. The city has two airports, including Mehrabad International Airport, and Imam Khomeini International Airport. Tehran relies heavily on private cars, buses, motorcycles, and taxis, and is one of the most car-dependent cities in the world. The Tehran Stock Exchange, which is a full member of the Federation Internationale des Bourses de Valeurs  and a founding member of the Federation of Euro-Asian Stock Exchanges, was one of the world's best performing stock exchanges in recent years..

. Problems arising from the late completion of the metro led to buses taking on the role of the metro lines, serving mainly long distance routes. Taxis filled the void for local journeys. The taxis only drive on main roads, and only within the local area, so it can be necessary to take several taxis to get to one's final destination. This has all led to extreme congestion and air pollution within the city.

Tehran is served by Mehrabad International Airport, the old airport which doubles as a military base located in the western part of the city, and Imam Khomeini International Airport, 50 kilometers south, which handles flights from the Persian Gulf Persian Gulf

[i] region, is an extension of the [[Gulf of Oman]... 

 but which will eventually handle all international flights. The new airport is more than overdue, but is efficient, although security concerns have made the governments of Britain and Australia warn their foreign nationals in Iran.

Tehran also has a central train station with connecting services round the clock to various cities in the country. There are four bus terminals that also provide connections at low fares. These are the South, East, West, and Bei-haghi Park-Drive Terminals.

Pollution


Tehran, like many big cities, suffers from severe air pollution and the city is often covered by smog Smog

Smog is a kind of air pollution [i] — the name is a portmanteau [i] of smoke [i] and fog [i]. ... 

 making breathing difficult and causing widespread pulmonary illnesses. It is estimated that about 27 persons die each day from pollution-related diseases.

The air pollution is due to several different reasons: 1) Economical: most Iranian industries are located on the outskirts of Tehran. The city is also overrun with old and aging cars which do not meet today's emission regulations. Furthermore, Iran's busiest airport, Mehrabad International Airport, is located in the west of the city; 2) Infrastructure: Tehran has a poor public transportation network. Buses and metros do not cover every area of the city. Most people are then obliged to either use private cars or hire taxis. This has created severe traffic and congestion; 3) Geographical: Tehran is bound in the north by the massive Alborz Alborz

The government, however, is engaged in a battle to reduce the air pollution. It has for instance encouraged taxis and buses to convert from petrol engines to engines that run on compressed natural gas Compressed natural gas

Compressed Natural Gas is a substitute for gasoline [i] or diesel [i] fuel [i]. ... 

. Furthermore, since 1979 the government of the Islamic Republic of Iran has setup a "Traffic Zone" covering the city center during peak traffic hours. Entering and driving inside this zone is only allowed with a special permit. The government is also trying to raise people's awareness about the hazards of the pollution. One method that is currently been employed is the installation of Pollution Indicator Boards all around the city to monitor the current level of particulate matter Particulate
