The  instrument is so sensitive that it can detect parts per billion of  hydrogen cyanide, a pollutant generated by fire and plentiful over Asia.  Measurements between 2004 and 2009 show an increase in hydrogen cyanide  in the stratosphere during the monsoons, which create a vortex over  Asia in the summers.<\/p>\n<p>The study&#8217;s authors say more time is needed to research the impact  of the pathway, but they add that the pathway can alter the makeup of  other gases in the stratosphere, like water vapor, and it can affect how  much solar heat reaches the planet (Margaret Munro, <a href=\"http:\/\/www.canada.com\/technology\/Monsoons%20create%20direct%20pathway%20pollution%20Study\/2725707\/story.html\" >Canwest  News Service<\/a>, March 25). <strong>&#8211; JP<\/strong><\/p>\n<p class=\"akst_link\"><a href=\"http:\/\/www.earthportal.org\/news\/?p=3241&amp;akst_action=share-this\"  title=\"E-mail this, post to del.icio.us, etc.\" id=\"akst_link_3241\" class=\"akst_share_link\" rel=\"nofollow\">Share This<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Greenwire: A Canadian satellite has discovered a direct route for Asian pollution to enter the upper atmosphere: monsoons.
