The smokestacks of Kremikovtzi steel mill on Sofia's outskirts may have shut down years ago, but ancient cars ensure that Bulgaria's capital is still the most polluted in Europe.
When the steel plant went bankrupt in 2008, it did little to improve the thick smog that still hangs over Sofia.
Experts say old cars and chronic traffic jams are to blame, made worse by the capital's location in a lowland surrounded by mountains.
Out of the 250,000 cars bought in 2013, only 20,000 were new, says Lyubomir Dorosiev, head of a used car dealer association.
