his winter fog and haze much of our attention, haze harmful, several cities have in its move, so we should strengthen environmental management efforts, not let the fog and haze rampant.Causes haze presumably a lot of people know, haze you, of course, by the fog and haze is composed of a large number of the main causes of fog suspended in the air, ground water droplets or ice crystals composed of tiny aerosol system, is near the ground floor air, water condensation product. The main causes fog reduced visibility, it will cause traffic problems, but there is little risk to people.Haze is dust in the air, sulfuric acid, nitric acid and other harmful material composition, it will make the atmosphere muddy, blurred vision and lead to reduced visibility, and the body will cause greater damage.
