爲什麽需要24小時在線監測VOCs？

VOCs排放源和其污染物排放量研究是大气VOCs治理的基础, VOCs气体来源非常广。

典型VOCs排放源可以分爲人爲排放源包括固定源和移動源及自然排放源包括生物源和非生物源兩大類，主要是人爲排放源，大多是石油化工及其他相關行業生産過程，産品消費行爲及機動車尾氣所引起。

VOCs會損害人體健康？

VOCs给人造成的伤害可谓从外而内、不择手段。一些VOCs会使皮肤产生丘疹和瘙痒，刺激眼鼻呼吸道和其他部位，造成眼，鼻和喉咙的炎症，严重者还会造成气喘，神志不清，晕倒，呕吐和支气管炎。更有甚者, VOCs很容易经呼吸道，消化道及皮肤等途径进入人体内，导致胃胀满，胃疼，伤及肝肾，累及中枢神经系统而引发头痛等不适。VOCs最杀手锏就是令大家都不寒而栗的两个词，那就是癌症。在室内长时间接触VOCs,可增加患肺癌，白血病，淋巴瘤等疾病的机会。

世界衛生組織（WHO）發布的環境致癌物報告中屬一級致癌物苯，芥子氣，氯乙烯，4-氨基聯苯，雙氯甲醚及工業品級氯甲醚，甲醛等對人有致癌證據，屬二級致癌物丙烯腈，四氯化碳，四氯乙烯，三氯乙烯，環氧乙烷，硫酸二甲酯，多氯聯苯類等有動物實驗致癌證據，屬三級致癌物苯乙烯，三氯乙烯等有動物實驗致癌物。而且毫無例外，以上物質均屬VOCs範疇。

爲什麽要對VOCs進行全天候的監控？

現階段人們已了解到的VOCs類型多樣複雜，如果判斷每種化學物質，定量分析地解剖，不僅用時較長，增加了成本，而且結果往往是不全面。工業園區VOCs在線監測能夠在一定範圍內了解總體排汙情況，盡管和定量化檢測准確性相比常常會有一定誤差，但是通過全天候在線監測能夠在廣度內掌握VOCs總體變化趨勢，得知生産和停工過程中VOCs轉換情況，進而掌握汙染物來源並爲進一步治理汙染提供數據基礎。

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.
