A widely used pesticide could be placing frog populations in danger by diminishing their ability to reproduce properly. Not only does exposure to the chemical linuron a potato herbicide reduce male frog fertility, it skews the sex ratios of growing tadpoles significantly towards females. The devastation pesticides have caused to insect populations has been well documented, with German scientists warning of an ecological Armageddon when they found numbers had plummeted by 75 per cent in the countrys nature reserves. Knock-on effects further up the food chain are thought to be behind the disappearance of many bird species from the European countryside. But pesticides can have toxic effects on other animals too, and there has been a distinct lack of research into their effects on amphibians. To improve this situation, ecotoxicologist Dr Cecilia Berg of the University of Uppsala and a team of ... researchers set out to investigate the effects of linuron in the West African clawed frog. They found that the tadpoles grew ovaries substantially more than they grew testicles, an effect the team attributed to the endocrine disrupting or hormone disrupting properties of linuron, which could hinder production of testosterone. The male frogs exposed to the chemicals as tadpoles were less fertile and had certain feminine characteristics. While linuron is not licensed for use in the UK ... it is widely used in other parts of the European Union (EU) and North America.

The latest study to look at the long-term effects of Roundup, a popular weed killer developed by Monsanto in the 1970s, raises questions about the herbicide’s possible contributions to poor health in certain communities. The study, published Tuesday in JAMA, tracked people over the age of 50 in southern California from 1993-1996 to 2014-2016, with researchers periodically collecting urine samples during that time. The percentage of people who tested positive for a chemical called glyphosate, which is the active ingredient in the herbicide Roundup, shot up by 500% in that time period. The levels of glyphosate also spiked by 1208% during that time. One trial from the UK, in which rats were fed low levels of glyphosate throughout their lives, found that the chemical contributed to a higher risk of nonalcoholic fatty liver disease, a condition in which fat accumulates in the liver and contributes to inflammation and scarring of the tissue. [Researcher Paul] Mills says that the levels of glyphosate documented in the people in his study were 100-fold greater than those in the rats. While Roundup was developed to eliminate most weeds from genetically modified crops — and thus reduce the amount of pesticides sprayed on them — recent studies have found that many weeds are now resistant to Roundup. That means growers are using more Roundup, which could only exacerbate potential negative health effects on people who consume those products.
Note: Bayer recently agreed to a $10 billion settlement over claims that its glyphosate-containing product RoundUp causes cancer. Meanwhile, Mexico is banning glyphosate and GMO corn.

Adding fluoride to public drinking water for dental purposes has been controversial since the practice first began in 1945. A new study suggests that prenatal exposure to this chemical may affect cognitive abilities and that children born to mothers exposed to high amounts of fluoride could have lower IQs. The study ... found an association between lower intelligence and prenatal fluoride exposure in 299 mother-child pairs in Mexico. Even when other possible factors were taken into account, such as exposure to other chemicals, results continually showed that higher prenatal fluoride exposure was linked to lower scores on tests of cognitive function in children at age 4 and then again between 6 and 12. The mothers in this study did not have fluoride added to their water. In Mexico, fluoridated salt is the main way that women get salt into their diet, says Hu, unlike in the U.S., where fluoridated water is the main avenue. The data could renew the debate about the safety of adding fluoride to tap water, in part because experts have not been quick to dismiss the findings. "This is a very well-conducted study, and it raises serious concerns about fluoride supplementation in water," says Dr. Leonardo Trasande, a pediatrician who studies potential links between environmental exposures and health problems at New York University. Trasande ... also explains that fluoride is known to disrupt thyroid function, which in turn is crucial for brain development.
Note: Another Newsweek article and this MSNBC article also raise serious questions about the benefits and risks of fluoride in our water. For more along these lines, see concise summaries of deeply revealing health news articles from reliable major media sources.
For decades, some of the dirtiest, darkest secrets of the chemical industry have been kept in Carol Van Strums barn. The ... structure in rural Oregon housed more than 100,000 pages of documents obtained through legal discovery in lawsuits against Dow, Monsanto, the Environmental Protection Agency, the U.S. Forest Service, the Air Force, and pulp and paper companies, among others. As of today, those documents and others ... will be publicly available through a project called the Poison Papers. The library contains more than 200,000 pages of information and lays out a 40-year history of deceit and collusion involving the chemical industry and the regulatory agencies that were supposed to be protecting human health and the environment, said Peter von Stackelberg, a journalist who along with the Center for Media and Democracy and the Bioscience Resource Project helped put the collection online. Van Strum didnt set out to be the repository for the peoples pushback against the chemical industry. But [in 1974] she realized the Forest Service was spraying her area with an herbicide called 2,4,5-T. The chemicals hurt people and animals. Residents ... filed a suit that led to a temporary ban on 2,4,5-T in their area in 1977 and, ultimately, to a total stop to the use of the chemical in 1983. For Van Strum, the suit was also the beginning of lifetime of battling the chemical industry. We didnt think of ourselves as environmentalists, that wasnt even a word back then, Van Strum said. We just didnt want to be poisoned.
Note: The herbicide 2,4,5-T is a main ingredient of Agent Orange. As recently as 2012, Monsanto, a manufacturer of Agent Orange, agreed to pay $93 million to settle claims of this poison's pollution of a US town.

Children exposed to relatively high levels of PCBs in the womb may have an increased risk of developing autism, a new study suggests. PCBs, or polychlorinated biphenyls, are man-made chemicals once used in a wide range of products, from electrical appliances to fluorescent lighting. Use of these chemicals was banned in the 1970s because of concerns about their health effects. But since they do not easily break down, PCBs still linger in the environment - and in people. In the new study, researchers found that when pregnant women had relatively high levels of certain PCBs in their blood, their children were about 80 percent more likely to be diagnosed with autism versus other kids. Those children also had a roughly twofold higher risk of intellectual disabilities unrelated to autism. "Autism is a complex condition with many different causes, and those causes vary among individuals," said Kristen Lyall, lead researcher on the study. Experts believe that for children to develop autism, they have to have a genetic susceptibility and be exposed to certain environmental factors during critical periods of early brain development. Researchers are still trying to figure out what those environmental factors are. But some suspects include prenatal exposure to poor nutrition, certain infections, heavy air pollution and pesticides, according to the non-profit Autism Speaks. The new findings suggest that PCBs could be another one of the "puzzle pieces," said Lyall.
Note: Monsanto and other chemical manufacturers spent decades dumping PCBs in low-income areas. For more along these lines, see concise summaries of deeply revealing news articles on corporate corruption and health.
As part of an ongoing effort to exploit medical intelligence, the National Security Agency teamed up with the military-focused Defense Intelligence Agency to extract medical SIGINT from the intercepted communications of nonprofit groups starting in the early 2000s, a top-secret document shows. Medical intelligence can include information about disease outbreaks; the ability of a foreign regime to respond to chemical, biological, and nuclear attacks; the capabilities of overseas drugs companies; advances in medical technology; medical research, and the medical response capabilities of various governments, according to the document and others like it, provided by NSA whistleblower Edward Snowden. One of the more prominent examples of focused medical spying came in 2010, when the agency crafted a plan to stow tracking devices with medical supplies bound for an ill Osama bin Laden in order to locate the terrorist leader. One article from August 2003 identifies an NSA project to keep an eye on the evolution of biotechnology in various countries. Can we ... determine the specific features that would distinguish a Bio Warfare Program from a benign civilian pharmaceutical production effort? the author wrote, identifying a suspect Iranian [biological warfare] facility as a target for inspection. Medical intelligence gathering has continued since then, according to the so-called black budget proposed for the 2013 fiscal year, published in February 2012.
