Environmental Contaminants Encyclopedia

Organization of each entry

To become familiar with the organization of each file, first search for a topic with the search engine, then double click on any Contaminants Encyclopedia file with the ".pdf" target="_blank" extension. Once the file is open:

  1. First single click on the "bookmark" button (usually third from the left on the upper tool bar in internet versions) to bring up a split screen showing the bookmarks, and then
  2. Move down the list of bookmarks on the narrow split screen to the left and single click on each bookmark in turn to move through and become familiar with the major headings. The same procedure may be used to bring up bookmarks in any of the PDF files provided herein.

    Note: The bookmark button always has text to the right and bullets with lines to the left. On certain (not all) computer/browser/ISP combinations, the bookmarks take a while to load the first time the bookmark button is clicked. In subsequent uses, the conversion is much faster.

Details of the organization (standard fields) within each entry is provided as follows. When already in a PDF file, the easiest way to find these headings is to use the bookmarks. One can also move to any of the following headings by using the Adobe Acrobat "Find" function (the stand-alone binoculars on the tool bar):
