Pollutants that act like hormones flush into lakes and streams worldwide from farm runoff and treated sewage. Scientists worry about these compounds’ presence in aquatic food webs because studies have connected them to feminized fish. Now, researchers report that endocrine-disrupting chemicals could accumulate in the brownish-green slimes called biofilms that coat stream and lake bottoms (Environ. Sci. Technol., DOI: 10.1021/es2000134). Their buildup there could make them a convenient meal for aquatic wildlife.

The Laundry Cost Calculator uses a dozen drop-down menus as variables to come up with the final number. It displays the final estimated cost per load, cost per month, and cost per year, based on water/power/gas usage needed to both wash and dry your clothes. It’s not exactly pretty, but it’s thorough, and it allows you to calculate two different scenarios at once for comparison.
