November 6, 2018, Cary Institute of Ecosystem Studies Sixty-nine pharmaceutical compounds have been detected in stream insects, some at concentrations that may threaten animals that feed on them, such as trout and platypus. When these insects emerge as flying adults, they can pass drugs to spiders, birds, bats, and other streamside foragers. These findings by an […]

Nicholas J. Niemuth, Rebecca D. Klaper Highlights Fish were exposed to metformin at concentrations relevant to wastewater effluent. Exposure from early life stages to adulthood caused intersex in male fish. Exposure caused a reduction in fecundity and in overall size of male fish. Results suggest that metformin is a potential endocrine disruptor in the environment. […]

To River Watch readers: Our website has had several articles in the past on the impacts of endocrine disruptors in streams and other waters of the USA. Most of these chemicals come from pharmaceutical sources released through normal waste discharge without being filtered or treated. What has been revealed is that, unlike many other potentially […]

Extensive results challenge a core assumption in toxicology by Pete Myers, Ph.D. and Wendy Hessler The “dose makes the poison” is a common adage in toxicology. It implies that larger doses have greater effects than smaller doses. That makes common sense and it is the core assumption underpinning all regulatory testing. When “the dose makes […]

University of Iowa-led research shows some drugs can partially regenerate themselves Assessing the risk posed to aquatic organisms by the discharge of certain steroids and pharmaceutical products into waterways is often based on a belief that as the compounds degrade, the ecological risks naturally decline. But there’s growing sentiment that once in the environment, some […]

Hi all! I just received this article, EPA Responds to Scientists’ Concerns about Low Dose Hormones,  stating that the EPA will begin to study low dose effects of endocrine disrupting chemicals. It is just a first step, but an incredibly important one. This can represent a sea change in how toxicity is assessed and may […]

April 12, 2012 The fluorescent fish has shown that oestrogenic chemicals, which are already linked to reproductive problems, impact on more parts of the body than previously thought. The research by the University of Exeter and UCL (University College London) is published today (April 18, 2012) in the journal Environmental Health Perspectives. Numerous studies have linked ‘endocrine-disrupting’ chemicals, […]

ScienceDaily (June 5, 2012) – Wastewater from large dairy farms contains significant concentrations of estrogenic hormones that can persist for months or even years, researchers report in a new study. In the absence of oxygen, the estrogens rapidly convert from one form to another; this stalls their biodegradation and complicates efforts to detect them, the […]

Just about all of these concerns can be addressed if toxicology moved toward a nonanimal approach. The method of using animals originated in the 1930-60 and is completely outdated today. The blueprint for development and implementation of alternatives is the National Research Council report, Toxicity Testing in the 21st Century: A Vision and a Strategy […]

In a 2004-2009 study, USGS scientists found that pharmaceutical manufacturing facilities can be a significant source of pharmaceuticals to the environment. Effluents from two wastewater treatment plants (WWTPs) that receive discharge from pharmaceutical manufacturing facilities (PMFs) had 10 to 1000 times higher concentrations of pharmaceuticals than effluents from 24 WWTPs across the nation that do […]
