Those who’ve traveled extensively in the developing world will not be overwhelmed by air pollution even in Panama [1]’s most congested urban areas. But this problem is growing, particularly as more and more cars clog Panama’s roads. Parts of Panama City [2] register well above acceptable limits for airborne toxins.
In the past, strong winds kept Panama City’s air relatively fresh. In recent years, however, a brown haze hangs over the city more and more often.
