Many states and local governments, as well as the federal government, have passed legislation, referred to as right-to-know laws, that requires the release of information on the hazards associated with chemicals produced or used in a given facility. Most right-to-know laws address both community and employee access to information about potential hazards. Requirements of these laws usually include providing public access to information on hazardous materials present, conducting inventories or surveys, establishing recordkeeping and exposure reporting systems, and complying with labeling regulations. Notification of emergency releases of hazardous substances into the environment is also required under right-to-know laws, such as the Federal Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA).

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
