Clemson University and Georgia Institute of Technology scientists are reporting in Science Express, a refinement of alginate is a promising new binder material for lithium-ion battery electrodes that not only could boost energy storage, but also eliminate the use of toxic compounds now used to manufacture the components.  In tests so far, it has helped boost energy storage and output for both graphite-based electrodes used in existing batteries and silicon-based electrodes being developed for future generations of batteries…Read more

Watch for blue-green algae http://www.microbexpert.com/blog/2011/09/late-summer-at-the-lake-watch-for-blue-green-algae.html http://www.microbexpert.com/blog/2011/09/late-summer-at-the-lake-watch-for-blue-green-algae.html#comments Thu, 15 Sep 2011 04:43:08 +0000 admin http://www.microbexpert.com/blog/?p=1346 SPOKANE – The Washington Department of Ecology (Ecology) is reminding residents of Eastern Washington who live on or near lakes or who visit lakes, to keep children and animals away from blooms of blue-green algae because they can be toxic.

When an algal species reproduces rapidly and reaches high concentrations, it is called an algae bloom. The algae blooms show up every year in many of our lakes and even rivers, often in late summer or early fall when the water is warm, sunshine is abundant and the weather is calm. However, they can occur at any time. Within only a few days, a clear lake can become cloudy.

The problem comes when a bloom produces toxins. Although many blue-green blooms are not toxic, some blue-green algae produce nerve or liver toxins. Toxicity is hard to predict since single species of algae can have both toxic and non-toxic strains.

Some dangerous kinds of algae produce a toxin that is found most often in the scum that people can see on top of the water. Only laboratory tests can confirm whether a bloom is toxic or non-toxic…Read more

Adrian Reyes-Prieto of the University of New Brunswick is studying the evolution of these ancient organisms, aided by a federal grant.

As part of a Canada Foundation for Innovation grant announced last Thursday, Reyes-Prieto received more than $169,000 to help outfit and staff his lab…Read more

Todd Lovin, park manager, said that with this warning there is to be “no direct water contact,” including swimming or renting canoes or kayaks due to the risk of tipping over. However, the River Pond Area is open to those with fishing boats.

The prime reason a warning has been issued for the River Pond Area is due to the toxins that blue-green algae produce. These toxins have the potential to make humans and animals sick or even cause death…Read more

Routine water monitoring results provided by the Bay of Plenty Regional Council confirms the levels of blue-green algae in the areas affected are now within safe limits.

Medical Officer of Health Dr Neil de Wet says that while there are currently no algal blooms of concern they can occur rapidly and unpredictably, especially during the summer months…Read more

Water monitoring has confirmed the presence of blue-green algae that can produce toxins harmful to humans and animals. These algae levels are likely to be associated with dangerous toxin concentrations in the water, according to World Health Organization guidelines.

Swallowing or inhaling water droplets should be avoided, as well as skin contact with water by humans or animals…Read more

West Virginia environmental officials responded; after months of deliberation, they issued what amounted to slap-on-the wrist penalties.

Unfortunately for Consol, the Dunkard Creek kill didn’t end at the Monongalia County line. The stream flowed onward into Pennsylvania, wiping out life on that side of the border, too. Now Pennsylvania fisheries officials are taking action, and they appear to be made of sterner stuff than their Mountain State counterparts…Read more

After searching a few different marinas and camp sites, only one boat and one family fishing were spotted.

Many people who live in the area were driving around, running errands and exercising in the beautiful weather, but vacationers just weren’t around.

“The most I’ve seen today are the people with the campers, I haven’t seen a lot of boating, or boaters passing by today,” Tracy Gilley said, Tackle Box Too Manager.

Boaters and fisherman scared away by either the algae or the high winds…Read more
