| 工业废气对人体健康的危害 Harm of Industrial Exhaust Gas to Human Health 人需要呼吸空气以维持生命。一个成年人每天呼吸大约2万多次，吸入空气达15～20立方米。因此，被污染了的空气对人体健康有直接的影响。 People need to breathe air to keep alive. An adult breathes about 20,000 times a day and inhales 15 to 20 cubic meters of air. Therefore, polluted air has a direct impact on human health. 大气污染物对人体的危害是多方面的，主要表现是呼吸道疾病与生理机能障碍，以及眼鼻等粘膜组织受到刺激而患病。 The harm of atmospheric pollutants to human body is manifested in many aspects, including respiratory diseases and physiological dysfunction, as well as irritation of mucosal tissues such as eyes and nose. 对植物的危害 Harm to plants 大气污染物，尤其是二氧化硫、氟化物等对植物的危害是十分严重的。当污染物浓度很高时，会对植物产生急性危害，使植物叶表面产生伤斑，或者直接使叶枯萎脱落；当污染物浓度不高时，会对植物产生慢性危害，使植物叶片褪绿，或者表面上看不见什么危害症状，但植物的生理机能已受到了影响，造成植物产量下降，品质变坏。 Atmospheric pollutants, especially sulfur dioxide and fluoride, are very harmful to plants. When the concentration of pollutants is very high, it will cause acute harm to plants, causing the surface of plant leaves to be damaged, or directly causing the leaf to wither and fall off; when the concentration of pollutants is not high, it will cause chronic harm to plants, making the leaves of plants chlorotic, or seemingly invisible harmful symptoms, but the physiological function of plants has been affected, resulting in the decline of plant production and deterioration of plant quality. |
