Tehran Plunged in Smog
TEHRAN, Iran, December 8, 1999 , (IRNA) -- Air pollution in Tehran Wednesday morning reached its climax, plunging the city into a halo of smog.
Air pollution indicators on panels installed at several crossings in the capital, showed pollutants such as carbon monoxide and suspended particles as high and above ''dangerous'' level in the morning. However, despite constant warnings of the traffic control center, most streets in the capital were crippled with heavy traffic jams caused by vehicles mostly traversing in the city with a single passenger.
Over two million vehicles travel in the megalopolis, causing 72 percent of the pollution in the city.
