Silver Nanoparticles Can Mutate and Kill Fish Embryos

Posted on Nov 25, 2009 by Derek Markham.

Nanoparticles of silver are in more than 200 different products on the market as anti-microbial agents, but scientists are now questioning whether the practice is safe for our environmental and personal health. Nanoparticles, silver in particular, get washed down the drain and into our waterways, exposing fish and other aquatic life and raising big concerns about the potential effects.

Water Supplies Tainted by Artificial Sweeteners

Posted on Aug 05, 2009 by Jennifer Lance.

Municipal water supplies contain “significant amounts” of artificial sweeteners, according to a new study from the Water Technology Centre in Karlsruhe, Germany.  Featured in the peer-reviewed scientific journal Analytical and Bioanalytical Chemistry, the study found water treatment does not remove the artificial sweeteners.  Natural News writes:

Researchers from the Water Technology Centre in Karlsruhe, Germany examined levels of seven common sweeteners – acesulfame, saccharin, aspartame, cyclamate (currently banned in the US and Canada), sucralose, neotame and NHDC – using a new method that enables detection of the substances simultaneously. Analysis of the water samples revealed that up to 80% and 59% of sucralose and acesulfame remained respectively, despite treatment and advanced filtration. Acesulfame was found to be the most treatment resistant sweetener, with several hundred nanograms of saccharin and cyclamate also remaining.

Biologists Warn 3 Pesticides Harm Salmon

Posted on May 15, 2009 by Jennifer Lance.

Three common agricultural pesticides carbaryl, carbofuran and methomyl are jeopardizing the survival of salmon and steelhead in the Pacific Northwest.  Federal biologists warn these pesticides can affect andronomous fishes’ abilities to smell, swim, grow, and avoid predators, and ultimately will kill them in certain concentrations.  The National Marine Fisheries Service is recommending restrictions and bans be placed on these pesticides’ applicationa near salmon habitat.
