Chemicals & Chemical Byproducts In The Great Lakes
The Alliance indicates that more troubling is that "these pharmaceuticals represent just a fraction of the chemical contaminants that make up what some researchers look upon as a vast chemical soup stretching from Minnesota to New York." The study reports that many emerging contaminants are found in the Great Lakes today, among them flame retardants, modern pesticides, pharmaceuticals, the antibacterial and antifungal agent Triclosan, and the insect-repellent DEET. The now-notorious bisphenol A (BPA), commonly used in a wide variety of plastics such as baby bottles and food packaging, was found in more than half the water samples analyzed in all the studies to date.
The report, Emerging Contaminant Threats and the Great Lakes: Existing science, estimating relative risk, and determining policies, says there's too little data from the lakes and not enough understanding of the effects of these emerging contaminants. "What is known, it concludes, is worth worrying about." Dr. Rebecca Klaper, Shaw Associate Professor at the Great Lakes WATER Institute in Milwaukee and lead author of the report said, "Exposure to some of these chemicals . . . is cause for consternation for people and concern over fish and wildlife impacts."
The Alliance is calling for legislation to reform the federal Toxic Substances Control Act (TSCA), the 1976 law from which EPA derives its authority to require reporting, record-keeping and testing of chemical substances. Among the needed reforms they are calling for: Grant the EPA administrator the ability to act immediately on chemicals we know are dangerous, such as persistent and bioaccumulating toxics, asbestos and formaldehyde; Require chemical manufacturers to provide basic information on the health and environmental hazards associated with their chemicals, and grant the public full access to information about a chemical's safety; and Ensure chemicals meet a standard of safety for all people -- including children, pregnant women and workers.
New App Provides Beach Water Quality & Information
Currently in the beta testing phase, the app retrieves advisory and closure data from the states of Michigan, Indiana and Ohio, all of which utilize BeachGuard, a centralized reporting database for monitoring data collected by health departments across each state. Data from the other Great Lakes states will be incorporated in time for the app's full launch in May 2012. The app was designed for the Android platform by LimnoTech, a water resources and engineering company based in Ann Arbor, MI, in partnership with GLC and the states. A mobile-enhanced website available on the Great Lakes Information Network will offer complementary information for other mobile devices. Funding is being sought to develop a corresponding native app for the iPhone.

Autumn Leaves (Litterfall) Mercury Pathway Equals Precipitation
USGS research hydrologist Martin Risch said, "Before these studies, we didn't know the extent of litterfall as a mercury pathway in different types of forests across the eastern U.S. Our research found that annual amounts of mercury deposited in autumn litterfall from deciduous forests were equal to or exceeded the annual amounts deposited in precipitation." Most of the mercury that eventually ends up in fish and food webs comes from the air, and much of the mercury in the air comes from human sources such as coal-fired power plants, industrial boilers, cement manufacturing, and incinerators. Forest canopies naturally remove mercury from the air and incorporate the mercury into and onto the leaves and needles of trees.
USGS scientists researched mercury levels in litterfall from forests over a three-year period in 15 eastern U.S. states. When they compared the results to those from a separate study of mercury in precipitation within the Great Lakes region, they found similar geographic patterns for mercury in litterfall and mercury in precipitation: Both types of mercury deposition were generally high in the same areas and low in the same areas. Risch said, "The similar geographic patterns indicate that the same mercury emissions sources affecting mercury levels in precipitation in an area also may affect mercury levels in forests and litterfall in that same area."
Furthermore, USGS said the precipitation study found no improvement in the amount of atmospheric mercury deposited by precipitation in the Great Lakes region over a 7-year period, and found that the amount of precipitation in the region had increased during this time. This precipitation study covers a time period that precedes new regulations by U.S. EPA to reduce mercury emissions in the U.S.
