曆史上的霧霾災害

最近幾年，“霧霾”頻繁出現在新聞媒體報道以及大衆口中。由于工業生産排放的二氧化硫等汙染物質，汙染大氣，天空出現灰蒙蒙一片的樣子，人們不得不戴上口罩出行。其實，霧霾並不只是近幾年才出現的問題，早在20世紀，西方國家就經過了慘重的教訓。

曆史上的霧霾災害

英國

英國是最早开展工业革命的国家，蒸汽机排放出大量的烟尘和二氧化碳，几年后空气污染的弊端就显示出来了。1873年，一场灰色的雾霾席卷英國。根据统计，在1879-1880年的冬天，有3000人死于雾霾。

此後在1952年，災難再次降臨。由于冬季居民大量燃煤，爆發了嚴重的霧霾災害。這就是著名的倫敦煙霧事件，根據統計，在此次霧霾災害中，大約有10萬倫敦市民患上了哮喘等呼吸道疾病。

比利時

1930年，比利時马斯河谷爆发了一场雾霾灾害，马斯河谷聚集了一系列煤炭、重金属加工等重工业。1930年12月，大部分地区被浓雾掩盖，两天内就有63位居民因空气污染死亡。

巴西

1980的庫巴唐俨然是一座擁有10萬多人口的大城市，鋼鐵、化肥産業繁榮，然而當地的嬰兒死亡率居高不下，一度被認爲是死亡之谷。

美國

20世紀汽車産業繁榮，燃煤帶來的汙染沒有解決之際又出現了新的汙染源——汽車尾氣。此時普遍使用含鉛的汽油，導致鉛中毒率高。1940年，洛杉矶已經有250多萬輛汽車，再加上地形因素導致的空氣流動緩慢，很容易集聚化學煙霧。1943年，洛杉矶上空漂浮著藍色的煙霧，氣味刺鼻。這就是著名的洛杉矶光化學汙染事件。

While they were discussing him, he returned suddenly and said: "And what is sa-kee, please?" "Life is strife indeed to her," I said. Both thanked me and buckled on their belongings, but Ferry's look was peculiarly intelligent; "I was in the small parlor, looking for you," he said; "I thought you would be near the music." And so he had seen Gholson with his revolver on him, and must have understood it! Bruce kissed her behind the demure corner of a Japanese screen. His eyes were dancing with mischief and pleasure. However large the crowd, it was silent as death when the priest Jacobs addressed them. He spoke words of encouragement, hope, and confidence, and urged them to send up their prayers to God Almighty—prayers for peace. When he had ended, these thousands sang the "Hymn to Mary," in18 such perfect order as if only one superhuman body sent forth an immensely powerful sound from earth to Heaven. collars and the material for a new blouse and a jar of violet cream Accession of George II.—Characters of the King and Queen—Adroit Tactics of Walpole—Rise and Fall of Compton—Attitude of the Opposition—Congress of Soissons—Causes of Dispute with Spain—Stanhope's successful Negotiations with King Philip—Retirement of Townshend—Walpole Supreme—Peace Abroad and at Home—Walpole's System of Wholesale Bribery and Corruption—The Public Prisons—Duel between Pulteney and Lord Hervey—The Excise Scheme—Great Outcry—Withdrawal of the Bill—Walpole's Vengeance—Attack on the Septennial Act—Wyndham's Speech—Depression of the Opposition—Definitive Peace of Vienna—Gin Act—The Porteous Riots—The Prince of Wales and the Opposition—Application for an Increase of his Allowance—Birth of George III.—Death of Queen Caroline—Attempt to Reduce the Army—Disputes with Spain—"Jenkins' Ear"—Walpole's Negotiations—Secession of the Opposition—Further Difficulties with Spain—Declaration of War—Privateers and Reprisals—Vernon's Victory—Frederick invades Silesia—Assistance of England—Parliament Meets—Sandys' Motion—Walpole's Defence—Disasters of Maria Theresa—She throws herself on the Magyars—Misfortunes of the English Fleets—Vernon Repulsed from Carthagena—Power slips from the Hands of Walpole—His Last Battles—The Chippenham Election Petition—His Fall. "I say, tell that engineer to uncouple his engine and bring it back up here where the head-light'll cover the other side," said Shorty. "It'll make the other side as light as day and we kin see every move, while we'll be in the dark." "Yes, I reckon so." HoME 少妇合集小说ENTER NUMBET 004www.cqytl.net.cn
