When you visit any Web site, it may place a small text file, known as a "cookie" on your computer. The cookie allows the Web site to "remember" specific information about your visit while you are connected or when you return to that site. The Office of Management and Budget Memo M-10-22, Guidance for Online Use of Web Measurement and Customization Technologies (PDF, 1.03MB), 6/25/10, allows Federal agencies to use session and persistent cookies, defined below.
The cookie makes it easier for you to use the dynamic features of Web pages. Cookies from Environment Effects Web pages only collect information about your browser's visit to the site; they do not collect personal information about you. While visiting certain Environment Effects sites, you may occasionally encounter a Web page that automatically employs cookies to make it easier to use the dynamic features of these Web pages.
Environment Effects Web sites may use either single session (temporary) or multi-session (persistent) cookies. Session cookies last only as long as your Web browser is open. Once you close your browser, the cookie disappears. Persistent cookies are stored on your computer for longer periods.
Session Cookies: We use session cookies for technical purposes such as to enable better navigation through our site. The OMB Memo 10-22 Guidance defines our use of session cookies as "Usage Tier 1 – Single Session." This tier encompasses any use of single session Web measurement and customization technologies.
Persistent Cookies: Environment Effects uses persistent cookies to enhance the Web experience for our users. Persistent cookies remain on your computer between visits to Environment Effects until they expire.

For example, Environment Effects uses persistent cookies to enable a PubMed retrieval system feature called "MyNCBI." The persistent cookie retains user preferences such as search result filters, LinkOut displays, institutional icon links, document delivery services, etc. across user sessions. Users may opt out of the persistent cookie selection in their MyNCBI settings at any time. Environment Effects also uses persistent cookies to avoid repeated invitations to take the American Customer Satisfaction Inventory (ACSI) survey. The persistent cookies that block repeated survey invitations expire in 90 days. Environment Effects may employ persistent cookies in other ways consistent with our mission and the OMB guidelines to analyze use patterns and improve our users' experience on Environment Effects Web sites.
