Anyone interested in weighing in on changes to water-quality standards that will impact the Great Salt Lake is invited to a public meeting Tuesday, 6:30 p.m., at the Utah Department of Environmental Quality, 168 N. 1950 West, Salt Lake City.

One focus of discussion so far has been selenium's impact on the lake's habitat. Selenium is a naturally occurring mineral, but it can show up in ecosystems at higher levels due to industrial activity. At high enough levels, it can impact the reproductive success of nesting shorebirds. A new "tissue-based" selenium standard for the lake may become the first of its kind in the country.
