  • Gov't. Sprays Barium and Aluminum over South Florida Health Effects The health effects of the different barium compounds depend on how well the specific barium compound dissolves in water. For example, barium sulfate does not dissolve well in water and has few adverse health effects. Doctors sometimes give barium sulfate orally or by placing it directly in the rectum of patients for purposes of making x-rays of the stomach or intestines. The use of this particular barium compound in this type of medical test is not harmful to people. Barium compounds such as barium acetate, barium carbonate, barium chloride, barium hydroxide, barium nitrate, and barium sulfide that dissolve in water can cause adverse health effects. Most of what we know comes from studies in which a small number of individuals were exposed to fairly large amounts of barium for short periods. Eating or drinking very large amounts of barium compounds that dissolve in water may cause paralysis or death in a few individuals. Some people who eat or drink somewhat smaller amounts of barium for a short period may potentially have difficulties in breathing, increased blood pressure, changes in heart rhythm, stomach irritation, minor changes in blood, muscle weakness, changes in nerve reflexes, swelling of the brain, and damage to the liver, kidney, heart, and spleen. One study showed that people who drank water containing as much as 10 ppm of barium for 4 weeks did not have increased blood pressure or abnormal heart rhythms. We have no reliable ...

  • Radiation!!! - Alam Na,,,, The effect of mobile phone radiation on human health is the subject of recent interest and study, as a result of the enormous increase in mobile phone usage throughout the world (as of June 2009, there were more than 4.3 billion subscriptions worldwide[1]). Mobile phones use electromagnetic radiation in the microwave range. Other digital wireless systems, such as data communication networks, produce similar radiation. The WHO has classified mobile phone radiation on the IARC scale into Group 2B - possibly carcinogenic. That means that there "could be some risk" of carcinogenicity, so additional research into the long-term, heavy use of mobile phones needs to be conducted.[2] Some national radiation advisory authorities[3] have recommended measures to minimize exposure to their citizens as a precautionary approach. Many scientific studies have investigated possible health symptoms of mobile phone radiation. These studies are occasionally reviewed by some scientific committees to assess overall risks. A recent assessment was published in 2007 by the European Commission Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR).[4] It concludes that the three lines of evidence, viz. animal, in vitro, and epidemiological studies, indicate that "exposure to RF fields is unlikely to lead to an increase in cancer in humans".

  • Chemtrails, Stoke on Trent, England 2012 Took a series of photos and videos in a hour time span. You can clearly see the chemtrails being made in long lines in various places, and in that hour, they change from just a trail, to spreading into full clouds, and they do cover the sky within 5 hours. (Sorry, about the music not looping at the end and you hear my voice on one of the videos at the end, but oh well.) :) ................................................................................................................ For more than a decade, first the United States and then Canada's citizens have been subjected to a 24/7/365 day aerosol assault over our heads made of a toxic brew of poisonous heavy metals, chemicals, and other dangerous ingredients. None of this was reported by any mainstream media. The US Department of Defense [DOD] and military have been systematically blanketing all our skies with what are known as Chemtrails (also known as Stratospheric Aerosol Geoengineering).(2) These differ vastly from the usual plane contrails that evaporate rather quickly in the sky. Chemtrails do not dissipate. Rather, planes (fitted with special nozzles) release aerosols "lines" in the sky that do not evaporate. Multiple planes are deployed, flying parallel (or often "checkerboard" patterns) overhead; and soon the sky is blanketed with many grayish-white lines [miles and miles long, although this is changing]. At first, these lines are thin; but soon they expand and, in a short time, merge together. Our once ...
  • Marijuana Causes Cancer? Office of Environmental Health Hazard Assessment Prop 65 Implementation PO Box 4010 1001 I St., 19th Floor Sacramento CA 95812-4010 We are responding to OEHHA's request for scientific information regarding the carcinogenicity of marijuana smoke for hearings by the Carcinogen Identification Committee on November 19, 2007. The best current evidence is that marijuana smoke does not cause cancer. Even though it can contain various carcinogenic pyrolytic compounds similar to those found in tobacco smoke, the best epidemiological studies have failed to detect elevated cancer rates in marijuana smokers. One possible explanation is that the major psychoactive ingredient of marijuana, delta-9-tetrahydrocannabinol (THC) has anti-carcinogenic properties, whereas the major ingredient of tobacco, nicotine, is cancer promoting [Melamede[1]].

  • Recycling mercury from a manometer In this video the elemental mercury is removed from the manometer for recycling. The mercury collected is reused for new products after it has been triple distilled. A Manometer is a device to measure pressures. A common simple manometer consists of a U shaped tube of glass filled with some liquid. Typically the liquid is mercury because of its high density. Elemental mercury or metallic mercury is the element in its pure, 'un-combined' form. It is a shiny, silver-white metal that is liquid at room temperature, but is rarely found in this form in nature. If not sealed off, mercury slowly evaporates into the air, forming a vapor. The quantity of vapor formed increases as temperatures rise. Elemental mercury is traditionally used in thermometers and some electrical switches. In this case mercury was used in this manometer. Elemental mercury is toxic to the nervous system. Humans are mainly exposed by inhaling vapors. These are absorbed into the body via the lungs and move easily from the bloodstream into the brain. The inhalation of elemental mercury vapors can cause neurological and behavioral disorders, such as tremors, emotional instability, insomnia, memory loss, neuromuscular changes and headaches. They can also harm the kidneys and thyroid. High exposures have also led to deaths. However, there is no evidence at present that elemental mercury causes cancer in humans and it has been classified by IARC into Group 3 "unclassifiable as to carcinogenicity in humans". If ...

  • Ca35fRev The LD50 test short for lethal dose, is one of the worst tests that was developed back in 1927 and is still in use today. Groups of animals are dosed with different amounts of a test substance in order to determine the dose which kills half of the animals! Animals are often force-fed the substance. The LD50 test is known to use huge, unrealistic doses that are completely unrelated to possible exposure levels. There are now other tests available that use less animals and lower doses, yet this old, discredited LD50 test continues.
  • Occupational cancer an introduction 1978 Clipped from the 1978 US government film, More than a Paycheck (narrated by John Wayne), the late Dr. Selikoff provides a brief introduction to this issue. Based on well-documented associations between occupational exposures and cancer, it is now estimated that approximately 20000 cancer deaths and 40000 new cases of cancer each year in the US are attributable to occupation. Millions of US workers are exposed to substances that have tested as carcinogens in animal studies. However, less than 2% of chemicals in commerce have been tested for carcinogenicity. OSHA regulates fewer than 30 sunstances as cancer causing. For more information and resources, go to the NIOSH website on occupational cancer at: www.cdc.gov

The evolution of the management and regulation of pesticides reflects changes in scientific understanding of pesticides as well as changes in human values. As technology allowed for testing of pesticides at smaller and smaller concentrations, restrictions on pesticide use grew. The government's growing understanding of cumulative risk also has led to changes in pesticide testing and regulation. 00:00 - Chapter 1.

  • Bottled Chemical Water Chemical contaminants in drinking water pose a health risk for all of us, although some people may be more vulnerable to these pollutants than the general population. These more sensitive populations include infants, the elderly, as well as people with weakened immune systems due to viral infections, immune disorders, cancer, chemotherapy or recent organ transplants (CDPH 2008; EPA 2005a). Concerned about tap water quality, some consumers turn to bottled water, hoping to find a guarantee of safety and quality (Doss 2008; IBWA 2008d). But the reality is very different from this expectation: all bottled waters tested by EWG contained some chemical contaminants while bottled waters sold by two national retailers contained signature pollutants at levels very close to water. WATER TREATMENT CHEMICALS: DISINFECTION BYPRODUCTS AND FLUORIDE Toxic disinfection byproducts (DBPs) such as chloroform, bromodichloromethane, and haloacetic acids, are formed when disinfectants (chlorine, ozone, chlorine dioxide or chloramine) react with organic matter, urban and agricultural contaminants, bromine, and iodide during the treatment of drinking water (EPA 2008a). While only eleven DBPs are currently regulated in the US, up to 600 different chemicals may form as byproducts of disinfection (Richardson 1998, 1999a,b, 2003), including 74 DBPs that are not regulated but that may be associated with either DNA damage or carcinogenicity (Richardson 2007).

Part 1 - An announcement last month from the International Agency for Research on Cancer of the World Health Organization (WHO/IARC) that they have classified radio frequency (RF) electromagnetic fields, such as those from mobile/cell phones, as possibly cancer-causing in humans has garnered apprehension particularly in Africa where the use of cell phones is the highest in the world. Despite modern era of information overdose and associated abuse, there are some organizations that, in the minds of public health professionals in particular and the general public in general, have an aura of authenticity. The World Health Organization (WHO) is one such organization. When the WHO comes up with a report that associates cancer to mobile phone usage, there is bound to be worldwide excitement. And for good reason. There is an estimated five billion mobile phone connections around the world. If mobile phones do indeed cause cancer, it is something to be actually worried about. But what did the IARC actually say and what does it mean? It was reported that 31 scientists from 14 countries met in Lyon, France, to pore over hundreds of previous scientific articles to assess the potential carcinogenic hazards from exposure to radiofrequency electromagnetic fields. The IARC Monograph Working Group, as the researchers are called, discussed and evaluated the available literature and concluded that the data was inadequate to draw ...
  • TV9 - Mobile Phone Tower Radiation Effect On Health : "Danger Tower" - 1/3 TV9 - Mobile Phone Tower Radiation Effect On Health : "Danger Tower" - 1/3......! The effect of mobile phone radiation on human health is the subject of recent interest and study, as a result of the enormous increase in mobile phone usage throughout the world (as of June 2009, there were more than 4.3 billion users worldwide[1]). Mobile phones use electromagnetic radiation in the microwave range. Other digital wireless systems, such as data communication networks, produce similar radiation. The WHO has classified mobile phone radiation on the IARC scale into Group 2B - possibly carcinogenic. That means that there "could be some risk" of carcinogenicity, so additional research into the long-term, heavy use of mobile phones needs to be conducted.[2] Some national radiation advisory authorities[3] have recommended measures to minimize exposure to their citizens as a precautionary approach.

  • SHOULD You Eat Organic? [SUBSCRIBE TO MY CHANNEL] [JOIN US ON MY FACEBOOK ARMY] [MY FEMALE WORKOUT CHANNEL!] [FOLLOW ME ON TWITTER] [MY FAT LOSS PROGRAM] [MY MASS AND STRENGTH PROGRAM] Common knowledge that our domestic produce is routinely sprayed with pesticides What's not clear is the effect that these 35000 + registered pesticides have on us, as fewer than a quarter have been tested for carcinogenicity, mutations and birth defects. The truth is we don't know how bad some of these pesticides are. The solution is to buy "organic" produce exclusively Number one that's very impractical, as it's ***ing expensive. And number two, the term "organic" is loosely regulated and enforced, not ensuring you get what you pay for. You always have to do your own research. The solution for the every man is the following, certain produce have exponentially higher levels of pesticides than others, and some have very low levels of chemicals The biggest common offenders that when possible should be bought organic are Berries (strawberries, blueberries, raspberries) Bell peppers Spinach Apples pears Celery Cucumbers Potatoes Those you don't have to worry about are: Sweet potatoes Onions Cabbage Avacados Pineapples Mangos Asparagus Grapefruits Watermelon Honeydew mellon Don't let our chemical laden produce prevent you from getting your fruits and veggies.

  • Geo Engineering Chemtrail Activity - Orange County CA. 11/30/2010 Aluminum Poisoning: Brain Injury Even with the increases in preventable illnesses, the issue that has not been linked or addressed --with what Clifford Carnicom rightly calls "aerosol crimes"-- is the deterioration of cognitive function. Our immune system is already under siege daily; and this has resulted in millions (possibly billions) of people with not just one illness, but often multiple ones. The skin, the largest organ in our body, is a permeable membrane. This means that invisible toxins in our air, including Chemtrails and other highly dangerous chemicals, go right into our skin. Poisoned rainwater (or snow touching our skin) does the same thing. When the air we breathe is filled with a dangerous assortment of toxins, with each breath we take, these poisons assault our entire immune system. These poisons also affect our brain and, thus, our cognitive function. Aluminum is a major component in these aerosols. Although it is our planet's most abundant metal, our body has no biological need for it. Pesticide Action Network North America [PANNA] lists it as "toxic to humans, including carcinogenicity, reproductive and developmental toxicity, neurotoxicity, and acute toxicity."(12) Yet, aluminum is commonly used [this is a very short list] in vaccines, deodorants and anti-perspirants, over-the-counter medications, soft drink and beer cans [aluminum leeches from the cans], baking powder, cake mixes, processed cheeses, and other food products and additives. Over years ...
  • Formation of a carcinogen (polycyclic aromatic hydrocarbons) This 3D animation shows how the heat from tobacco combustion causes molecules to fragment into unstable arrangements, which recombine to form carcinogenic compounds of polycyclic aromatic hydrocarbons.
  • Pyrethroid Project v3.avi Although the use of pyrethroids for mosquito adulticide has been in use for several decades, it has increased in recent years with the introduction of West Nile virus in the United States. Several studies have indicated that pyrethroids may have adverse effects on the human body. Research on mice has linked it to tumor growth and reproductive toxicity; however, EPA examination and reports have found Resmetherin, a pyrethroid, to be non-genotoxic but still at risk for carcinogenicity. This project summarizes our risk ***ysis conclusion and recommendations for decreasing exposure.
  • The Home Scientist 006 - Forensic Fingerprinting I: Iodine Fuming Use a tiny amount of crystal iodine (or substitute drugstore tincture of iodine) to reveal latent fingerprints on paper and other porous surfaces. Iodine fuming is the oldest method for revealing latent fingerprints, and is still in very wide use by professional forensics technicians. More information: Forensic Latent Fingerprinting Kit: Before anyone comments, a note about pronunciation. Many scientists pronounce iodine as eye-oh-deen--by ***ogy to the other halide elements, fluorine, chlorine, bromine, and astatine--rather than eye-oh-dyne. Many people born before 1940 pronounce it eye-oh-dinn. Any of the three is correct.

Just a few weeks later on March 8, Rumsfeld became the CEO of GD Searle to take point on a mission to force the Food and Drug Administration to approve for human consumption a known carcinogen and neurotoxic poison. Mission accomplished Today some 9000 commonly consumed products are laced with this weapon of mass misery and millions of people live with chronic illnesses linked to the artificial sweetener aspartame. It is our belief at The Idaho Observer that if some guy named Parkinson can have a disease named after him, then Donald Rumsfeld ought to have his own disease, too. Hence the term Rumsfeld disease A.

  • Artificial Sweeteners Warning: Long, science-heavy video. No funny cats or guys getting hit in the nuts. Artificial sweeteners, or as they are usually referred to in the literature "non-caloric" sweeteners or "high-intensity" sweeteners, address the problem of sugar calorie excess in our diet. They've been demonstrated to support weight loss or maintenance, reduce cavities and can be part of a healthy lifestyle.
