Haze-shrouded Beijing could restrict more cars and shut more factories if air pollution persists during the Olympic Games, a report said on Monday, as an environmental group said endurance athletes could face problems. Beijing has ordered many cars off roads and halted much construction and factory production in an effort to cut smog before the Games open on Aug. 8. But the city has still endured hazy skies over the past week, and again on Monday, raising fears that the sultry heat Beijing often experiences in August could make for a cocktail of haze, fumes and dust for tens of thousands of athletes and visitors.
