“Environmental factors that can affect one’s health include any influence exerted on the body after conception. These can include any events during fetal development and after birth – such as physical trauma, exposure to chemicals and infections, and nutrition. Some studies, but not all, indicate that pesticide use, rural living and the drinking of well water – all factors that increase exposure to pesticides – contribute to the development of PD. Pesticides are thought to adversely affect the brain by inhibiting energy production resulting in brain cell death. Studies have also shown that smoking and caffeine use appear to protect against the development of PD. However, it is universally agreed that the health risks associated with smoking are worse than any incidental benefits that might be gained by this habit.”

The 8th edition of MLA has resulted in changes to the citation format. Correcting the citations on our website will take some time. Until then, please reference the guidelines below to correct the citation format. You will still be using the information provided here, but you may need to adjust the format for MLA 8.

Most MLA citations on our site should follow this format:

Author, A. Title of Source. Publisher, Date, URL. Accessed, 1 Jan 2050.
"Web." removed
  • Medium of publication does not need to be stated if obvious.
  • Listing the "name of the site" is not necessary if it is the same as the name of the publisher.
No brackets around URLs
  • URLs should be placed after the publication date, separated by a comma, and before the date accessed, with a period at the end.

For citing an article in a scholarly journal you will use the journal title instead of publisher, and retain any volume, issue, and page numbers. Use a DOI in place of URL if one is available.
