意大利八城市空气检测出毒品成分
<p>最近一项针对意大利八大城市空气成分的检测研究指出，各城市空气中都含有不同程度的可卡因和大麻成分，其中都灵空气中的毒品含量最高，佛罗伦萨空气中的大麻含量较高，而巴勒莫空气中的毒品含量最少。另外，研究人员还发现，全年空气检测中可卡因和尼古丁的含量相对稳定，而冬季时各城市空气中的大麻和咖啡因含量却明显高于夏季，他们认为这是季节性抑郁导致的。2006年罗马空气中检测出可卡因成分后，政府开始资助此项研究进行跟进，研究结果将有助于政府了解各地的毒品使用情况，并合理配置警力和戒毒资源。</p><p><span word="A">A</span> <span word="study">study</span> <span word="of">of</span> <span word="eight">eight</span> <span word="major">major</span> <span word="metropolitan">metropolitan</span> <span word="hubs">hubs</span> <span word="in">in</span> <span word="Italy">Italy</span>, <span word="published">published</span> <span word="this">this</span> <span word="week">week</span> <span word="in">in</span> <span word="the">the</span> <span word="journal">journal</span> <span word="Environmental">Environmental</span> <span word="Pollution">Pollution</span>, <span word="has">has</span> <span word="found">found</span> <span word="trace">trace</span> <span word="levels">levels</span> <span word="of">of</span> <span word="cocaine">cocaine</span> <span word="and">and</span> <span word="cannabanoids">cannabanoids</span> <span word="from">from</span> <span word="marijuana">marijuana</span> <span word="use">use</span>. <span word="The">The</span> <span word="researchers">researchers</span> <span word="also">also</span> <span word="monitored">monitored</span> <span word="the">the</span> <span word="more">more</span> <span word="pedestrian">pedestrian</span> (<span word="and">and</span> <span word="legal">legal</span>) <span word="drugs">drugs</span> <span word="of">of</span> <span word="abuse">abuse</span>, <span word="nicotine">nicotine</span> <span word="and">and</span> <span word="caffeine">caffeine</span>. <span word="The">The</span> <span word="study">study</span> <span word="is">is</span> <span word="a">a</span> <span word="government">government</span>-<span word="sponsored">sponsored</span> <span word="follow">follow</span>-<span word="up">up</span> <span word="to">to</span> <span word="a">a</span> 2006 <span word="study">study</span> <span word="in">in</span> <span word="Rome">Rome</span>, <span word="which">which</span> <span word="found">found</span> <span word="trace">trace</span> <span word="elements">elements</span> <span word="of">of</span> <span word="cocaine">cocaine</span> <span word="in">in</span> <span word="the">the</span> <span word="air">air</span>.</p><p><span word="Why">Why</span> <span word="measure">measure</span> <span word="atmospheric">atmospheric</span> <span word="coke">coke</span>?
