The Birth Control Pill Threatens Fish Reproduction
Posted on Apr 12, 2010 by Jennifer Lance.
An estimated 80 million women worldwide take oral contraceptives (aka “the Pill“) to “inhibit ovulation and thus prevent pregnancy”. First available to the public in the 1960s, the Pill has been pronounced as “the most significant medical advance of the 20th century”. Although the Pill revolutionized women’s health, traces of the contraceptive are ending up in treated wastewater and harming fish.

NY Proposes Recycling Cooling Water at Nuclear Power Plants
Posted on Mar 24, 2010 by Jennifer Lance.
When one thinks of nuclear power, images of cooling towers rising into the sky come to mind. Water is needed in nuclear power production in order to cool the “waste heat” generated and in case an accident occurs. The Union of Concerned Scientists explains:
For every three units of energy produced by the reactor core of a U.S. nuclear power plants, two units are discharged to the environment as waste heat. Nuclear plants are built on the shores of lakes, rivers, and oceans because these bodies provide the large quantities of cooling water needed to handle the waste heat discharge.

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.
