Fracking Releases 750+ Chemicals

Posted by feww on December 18, 2013

Hydraulic fracturing (fracking) releases endocrine-disruptors to the environment: Report

Endocrine disruptors (endocrine disrupting chemicals, EDCs) are chemicals that can interfere with the endocrine (or hormone system) in mammals, causing cancerous tumors, birth defects, and other developmental disorders.

“Hundreds of products containing more than 750 chemicals and components are potentially used throughout the extraction process, including over one hundred known or suspected endocrine disrupting chemicals,” says a new study on fracking.

Hydraulic fracturing (hydro-fracking) is credited as being first employed by Halliburton in 1948. The process injects a mixture of chemical additives, proppants (particles, like sand or ceramic), and water under high pressure into a target oil or gas zone in order to facilitate the flow of the gas or oil back to the surface for recovery. From 1999 to 2007, the Hydraulic Fracturing market expanded from just under $3 billion to 12.8 billion USD. [Global hydraulic fracturing market is forecast to grow from an estimated $31 billion in 2011, and  $40 billion in 2012 to $64 billion by 2017.] In 2009, the EPA and internal studies from natural gas companies themselves found that wastewater from this process contains levels of radioactivity and carcinogenic properties that are above the level that treatment plants are currently equipped to handle.

To determine the extent of the risks involved, researchers conducted tests on 12 suspected or known EDCs used throughout the extraction process and measured their ability to influence the body’s reproductive hormones.

The researchers then collected surface and ground water samples from various sites in Colorado, including the “drilling-dense” region of Garfield County with more than 10,000 active natural gas wells and compared them to samples taken from other sites in the state where heavy fracking is absent.

Samples from the areas near heavy-drilling sites showed higher levels of EDC activity, according to the Endocrine Society, including a greater presence of chemicals that disrupt both testosterone and estrogen.

Some of the samples showing high traces of EDCs weren’t necessarily taken from fracking sites, but from areas of Colorado where known spills had been reported.

“In comparison,” the report says, “little activity was measured in the water samples from the sites with little drilling.”

These harmful chemicals “could raise the risk of reproductive, metabolic, neurological and other diseases, especially in children who are exposed to EDCs,” says the report co-author Susan Nagel of the University of Missouri’s School of Medicine.

“The rapid expansion in drilling operations utilizing hydraulic fracturing increases the potential for environmental contamination with the hundreds of hazardous chemicals used,” says the report .

“With fracking on the rise, populations may face greater health risks from increased endocrine-disrupting chemical exposure.”

“Fracking is exempt from federal regulations to protect water quality, but spills associated with natural gas drilling can contaminate surface, ground and drinking water,” Nagel added. “We found more endocrine-disrupting activity in the water close to drilling locations that had experienced spills than at control sites.”

  • Authors: Christopher D. Kassotis, Donald E. Tillitt, J. Wade Davis, Annette M. Hormann and Susan C. Nagel
  • Abstract: The rapid rise in natural gas extraction utilizing hydraulic fracturing increases the potential for contamination of surface and ground water from chemicals used throughout the process. Hundreds of products containing more than 750 chemicals and components are potentially used throughout the extraction process, including over one hundred known or suspected endocrine disrupting chemicals. We hypothesized that a selected subset of chemicals used in natural gas drilling operations and also surface and ground water samples collected in a drilling-dense region of Garfield County, CO would exhibit estrogen and androgen receptor activities. Water samples were collected, solid-phase extracted, and measured for estrogen and androgen receptor activities using reporter gene assays in human cell lines. Of the 39 unique water samples, 89%, 41%, 12%, and 46% exhibited estrogenic, anti-estrogenic, androgenic, and anti-androgenic activities, respectively. Testing of a subset of natural gas drilling chemicals revealed novel anti-estrogenic, novel anti-androgenic, and limited estrogenic activities. The Colorado River, the drainage basin for this region, exhibited moderate levels of estrogenic, anti-estrogenic, and anti-androgenic activities, suggesting that higher localized activity at sites with known natural gas related spills surrounding the river might be contributing to the multiple receptor activities observed in this water source. The majority of water samples collected from sites in a drilling-dense region of Colorado exhibited more estrogenic, anti-estrogenic, or anti-androgenic activities than reference sites with limited nearby drilling operations. Our data suggest that natural gas drilling operations may result in elevated EDC activity in surface and ground water.  Copyright © 2013 by The Endocrine Society

Monsanto Chemical Found in Euro Urine

Posted by feww on June 15, 2013

“Quantifiable levels” of Monsanto herbicide found in urine samples from 18 Euro countries

In a recent study by Medical Laboratory Bremen in Germany humane urine samples from 18 European countries showed residues of Glyphosate and the metabolite AMPA.

“On average 44 % and 36 % of the urine samples analyzed were found to contain quantifiable levels of Glyphosate and AMPA, respectively,” said the report.

  • The frequency of detection ranged from 10% to 90%.  The highest Glyphosate concentration was 1,8 μg/L  in Latvia, followed by Malta, UK and Germany, while the highest AMPA concentration was 2,6 μg/L  found in Croatia.
  • A total of 6.6% of  samples showed residues that “significantly exceeded the tentative reference value of 0,8 μg/L forGlyphosate,” the report said.

The report concludes; “The results give a first idea to which extent adults in 18 European countries are exposed to Glyphosate. The regional and individual variations are large. Diet seems to be the main sources of exposure. However, more scientific work is needed to distinguish between different exposure situations.”

Glyphosate was discovered to be a herbicide by a Monsanto chemist and was marketed in the 1970s under the trade name Roundup.

Aminomethylphosphonic acid (AMPA), an organic acid, is one of the primary degradation products of the herbicide glyphosate.

Both Glyphosate and AMPA are said to have low toxicity, with glyphosate being an EPA Toxicity Class III chemical (on a scale of I to IV, Class I is most toxic) for oral and inhalation exposure.

In 2007, Glyphosate was the most used herbicide in the United States, with about 100,000 tons applied  by the agricultural sector, government and home and garden users.

NY sanity questioned as state plan shale gas drilling

Posted by feww on January 2, 2010

The Test of Sanity: Clean Water or Shale Gas?

Never mind their door steps, 9,000,000 New Yorkers could have their drinking water fouled

The U.S. Environmental Protection Agency (EPA)  warns New Yorkers about the real threat to their drinking water if they drill for shale Gas.

‘Diarrhea water’

But some residents say the drilling has clouded their drinking water, sickened people and animals and made their wells flammable. REUTERS/Tim Shaffer. Image may be subject to copyright.

EPA is temporarily halting the drive by energy companies to drill for gas in the state’s Marcellus Shale formation, said to contain enough natural gas to satisfy U.S. demand for at least 10 years, Reuters reported.

“We have concerns regarding potential impacts to human health and the environment that we believe warrant further scientific and regulatory analysis,” reported John Filippelli, chief of the agency’s Strategic Planning and Programs Branch on Wednesday.

“EPA has serious reservations about whether gas drilling in the New York City watershed is consistent with the vision of high-quality unfiltered water supply,” he wrote in .

New York City asked the state to ban shale gas drilling in the city’s watershed last week.

You can’t have your clean water and drill for gas near it, too!

Shale gas extraction known as hydraulic fracturing, or “fracking,” uses toxic chemicals that are known to pollute drinking water wells near the drill sites. AMAZINGLY, fracking is NOT covered by the U.S. Clean Water Act.

Despite the natural gas industry’s denials that drilling poses no risk to drinking water, EPA has previously admitted that  fracking chemicals are in fact contaminating drinking water. According to many reports “private wells near gas installations having water that is discolored, foul tasting, or even flammable because of methane that has escaped from drilling operations.”

“Theo Colborn, a researcher with the Endocrine Disruption Exchange who has drawn links between fracturing chemicals and a range of illnesses including cancer, said the EPA report indicates the agency was taking a new look at fracturing in light of growing public concern and media coverage.” Reuters said.

“The natural gas industry can’t keep saying it’s clean,” she said.

An environmental impact statement issued in September by the New York state Department of Environmental Conservation recommended  that energy companies be permitted to drill in New York’s Marcellus Shale formation.

“We’re pleased to see that the EPA recognizes what the state so far has not, that gas drilling is entirely inappropriate with in the drinking supply for 9 million people,” said James Simpson, a staff attorney for Riverkeeper, a New York environmental group.

New York City officials have warned the city could be forced to build a $10 billion filtration system if shale gas drilling is allowed.


EPA admits water contaminated near gas-drilling sites

FEWW wrote:

Now, for the first time ever, EPA scientists have revealed that drinking water wells  near natural gas [and oil] drilling operations contain chemical contaminants. They found dangerous chemicals in the water from 11 of 39 wells tested near the Wyoming town of Pavillion in March and May 2009.  Unfortunately, their report  falls shy of concluding what causes the contamination, though it admits the gas drilling is a potential source.

‘Diarrhea water’

In Dimock, Pennsylvania, drilling for natural gas has clouded the drinking water, sickened people and animals and made their wells flammable.

Isn’t it remarkable that two distant communities, one in Dimock, Pennsylvania, and the other in Pavillion, Wyoming, some 2,668 km (1,658 miles) apart, share a common fate by way of their contaminated drinking water, where the only common denominator between them is gas-drilling activities.

The Dementia Dozen: Foods to Avoid

Posted by feww on December 21, 2009

Should You Worry About Pesticides in Your Food?

That depends on whether you think dementia adds to your 50-something charm!

Exposure to pesticides could permanently affect the nervous system, increasing the risk of Alzheimer’s disease later in life, researchers say.

New findings support a probable link between toxic chemicals and Alzheimer’s disease.

“While no cause for Alzheimer’s disease has been found, [non-inherited] cases are likely due to a combination of genetic and environmental factors,” said Kathleen M Hayden, PhD, Duke University Medical Center in Durham, N.C.

Hayden’s research shows that pesticides could affect the rate of flow of acetylcholine, a chemical that’s important for memory.

More than 18,000 pesticides are licensed in the U.S., and about 1 million tons (2 billion pounds) are applied to fruit and crops each year, Hayden said.

“There are 5.3 million Americans [1.7 percent of the US population] living with Alzheimer’s disease, which disrupts memory, learning, and other mental functions. By 2010, there will be nearly half a million new cases each year and by 2050, there will be nearly a million new cases annually, according to the Alzheimer’s Association.” WebMed reported.

“The World Alzheimer’s Report 2009 estimates that 35 million people will have dementia worldwide by 2010. That is less than one half of one percent (0.5%)  of the world population.” ANZ Blog reported.

In a new study that involved 4,000 participants, researchers found that the likelihood of developing Alzheimer’s disease increased by 53% among people who worked with pesticides, having adjusted for other factors including age, gender, education and a gene known to raise Alzheimer’s risk.

Pesticide Exposure Linked to Parkinson’s, Alzheimer’s Disease

Two new studies provide additional evidence “pointing to a link between pesticide exposure and the risk for neurological disorders.” Medscape reported.

“One study linked high levels of an organochlorine pesticide called beta-hexachlorocyclohexane (beta-HCH) to an increased risk for Parkinson’s disease (PD), while another showed an association between agricultural pesticide exposure and dementia, including Alzheimer’s disease (AD).”

Persistent organochlorine pesticides

“[P]ersistent organochlorine pesticides (including DDT, dieldrin) were used widely in New Zealand. The main areas of use were agriculture, horticulture, timber treatment and public health (Table 1). Smaller amounts were also used for amenity purposes and in households.” New Zealand Government says.

“Organochlorine contamination: Some of the 60,000 or so synthetic organochlorines that have been formulated since about 1940 are highly persistent or long-lived (e.g. DDT, DDE, PCBs, PCP, HCBs, dioxins, chlordane, lindane, aldrin, dieldrin).” —Truth about New Zealand

Why Do Some Countries Score Much Higher on Parkinson’s, Alzheimer’s Cases?

In short, two reasons:  First, previous applications of now banned persistent organochlorine pesticides (including DDT, dieldrin); Second, the volume of pesticides applied.

ANZ believes there’s a direct relationship between the volumes of pesticides applied in a given country and numbers of dementia cases nationwide.

Pesticide manufacture

“New Zealand has ‘about a dozen’ pesticide manufacturing sites. No information is publicly available about the scale and extent of land contamination associated with these sites with the exception of ‘a disused site in the small coastal town of Mapua , on the Waimea inlet near Nelson. Various pesticides and agricultural chemicals were manufactured and formulated there from 1945 to 1988 by the Fruitgrowers Chemical Company.’”

“DDT was mixed with fertiliser and applied to pasture in a bid to control grass grubs and porina caterpillars. It was also used on lawns and market gardens, parks and sports fields. Its use …was finally banned in 1989. DDT has a half-life of 10 years in dry soils, but its main residue, DDE, is far more persistent, showing little change in soil levels over 20 years.”—Truth about New Zealand

The US study, “1 of the largest of its kind to date and perhaps the first to link a particular pesticide with PD, found that 9 of the 16 pesticides tested were present in study subjects. The pesticide found most often was p.pDDE. It was detected in 100% of the AD patients, 72% of the PD patients, and 86% of the controls.” Medscape report said.

How does that translate into your family’s food safety?

Safe Food Campaign List of  “The Dirty Dozen” food is reproduced below:

Safe Food Campaign research

Safe Food Campaign researcher Alison White has listed the top 12 foods in New Zealand that are most likely to contain pesticide residues.

White’s list of the ‘Dirty Dozen’ food is based on data complied by the New Zealand Food Safety Authority and includes Bread, dairy products and fruit, both fresh and canned.

They have ranked the food according to the most pesticide residues,  number of pesticides detected in total samples and the percentage contaminated with pesticides.

What about other food that are not on the list, but are contaminated nonetheless?

The ‘dirty dozen’ crops and farm produce that are listed on the table were closely followed by cucumber, nectarines, lettuce, tomatoes, wine and pears, according to safe food Campaign research.

How could that affect your kids’ health?

In Birth to Alzheimer’s in 12 products, quoting Food Safety researcher Alison White, ANZ says:

According to  a 2006 study, “children who were exposed prenatally to the organophosphate insecticide chlorpyrifos, as measured in the umbilical cord, were significantly more likely to have poorer mental and motor development by three years of age and increased risk for behaviour problems.” New Zealand uses  Chlorpyrifos on almost all grain, fruit and vegetables.  Apples, apricots, celery, grapes,  mandarins, oranges, pears, peaches, raisins, sultanas, tomatoes, as well as bread and wine, among others, were recently found to contain the toxic chemical.

“We do not know enough about the effects of these chemicals in our food. However, there are various serious long term effects associated with particular pesticides that are found in our food, including endocrine or hormonal disruption, cancer, immune system suppression, nervous system damage, genetic damage and birth defects. We also know that various pesticides used to grow food have damaging effects on wildlife and the ecosystem.”

The highly toxic chlorothalonil, a fungicide, believed to be a human carcinogen, is found in Celery. The deadly chemical “in laboratory studies has caused DNA damage and embryo loss.”  The EPA in the US intends to study Chlorothalonil as a potential endocrine disruptor. “This pesticide has also been found in groundwater, sea water and air and is toxic to many species, including earthworms.”

Celery also contain mancozeb, yet another fungicide, which breaks down to  ethylene thiourea and causes cancer, endocrine disruption, goitre and birth defects, the report said.

[Moderator’s Note: The parties involved seem to have intentionally left out any mention of the kiwifruit, possibly the most toxic of all NZ produce.]
