Bio-Tag: Genetically Modified Organisms (GMO)
The following text was sourced from here.
Genetically modified organisms (GMO’s) are a broad group of plants, animals, and bacteria that are engineered for a wide variety of applications ranging from agricultural production to scientific research. The types of potential hazards posed by GMO’s vary according to the type of organism being modified and its intended application. Most of the concern surrounding GMO’s relates to their potential for negative effects on the environment and human health. Because GMO’s that could directly effect human health are primarily products that can enter the human food supply, this website focuses on genetically modified food. To date, the only types of products that have been approved for human consumption in the U.S. are genetically modified plants (FDA website).
All genetically modified foods that have been approved are considered by the government to be as safe as their traditional counterparts and are generally unregulated (FDA website). However, there are several types of potential health effects that could result from the insertion of a novel gene into an organism. Health effects of primary concern to safety assessors are production of new allergens, increased toxicity, decreased nutrition, and antibiotic resistance (Bernstein et al., 2003).
Food Allergy
Food Allergy affects approximately 5% of children and 2% of adults in the U.S. and is a significant public health threat (Bakshi, 2003). Allergic reactions in humans occur when a normally harmless protein enters the body and stimulates an immune response (Bernstein et al., 2003). If the novel protein in a GM food comes from a source that is know to cause allergies in humans or a source that has never been consumed as human food, the concern that the protein could elicit an immune response in humans increases. Although no allergic reactions to GM food by consumers have been confirmed, in vitro evidence suggesting that some GM products could cause an allergic reaction has motivated biotechnology companies to discontinue their development (Bakshi, 2003).
Increased Toxicity
Most plants produce substances that are toxic to humans. Most of the plants that humans consume produce toxins at levels low enough that they do not produce any adverse health effects. There is concern that inserting an exotic gene into a plant could cause it to produce toxins at higher levels that could be dangerous to humans. This could happen through the process of inserting the gene into the plant. If other genes in the plant become damaged during the insertion process it could cause the plant to alter its production of toxins. Alternatively, the new gene could interfere with a metabolic pathway causing a stressed plant to produce more toxins in response. Although these effects have not been observed in GM plants, they have been observed through conventional breeding methods creating a safety concern for GM plants. For example, potatoes conventionally bred for increased diseased resistance have produced higher levels of glycoalkaloids (GEO-PIE website).
Decreased Nutritional Value
A genetically modified plant could theoretically have lower nutritional quality than its traditional counterpart by making nutrients unavailable or indigestible to humans. For example, phytate is a compound common in seeds and grains that binds with minerals and makes them unavailable to humans. An inserted gene could cause a plant to produce higher levels of phytate decreasing the mineral nutritional value of the plant (GEO-PIE). Another example comes from a study showing that a strain of genetically modified soybean produced lower levels of phytoestrogen compounds, believed to protect against heart disease and cancer, than traditional soybeans (Bakshi, 2003).
Antibiotic resistance
In recent years health professionals have become alarmed by the increasing number of bacterial strains that are showing resistance to antibiotics. Bacteria develop resistance to antibiotics by creating antibiotic resistance genes through natural mutation. Biotechnologists use antibiotic resistance genes as selectable markers when inserting new genes into plants. In the early stages of the process scientists do not know if the target plant will incorporate the new gene into its genome. By attaching the desired gene to an antibiotic resistance gene the new GM plant can be tested by growing it in a solution containing the corresponding antibiotic. If the plant survives scientists know that it has taken up the antibiotic resistance gene along with the desired gene. There is concern that bacteria living in the guts of humans and animals could pick up an antibiotic resistance gene from a GM plant before the DNA becomes completely digested (GEO-PIE website).
It is not clear what sort of risk the possibility of conferring antibiotic resistance to bacteria presents. No one has ever observed bacteria incorporating new DNA from the digestive system under controlled laboratory conditions. The two types of antibiotic resistance genes used by biotechnologists are ones that already exist in bacteria in nature so the process would not introduce new antibiotic resistance to bacteria. Never the less it is a concern and the FDA is encouraging biotechnologists to phase out the practice of using antibiotic resistance genes (GEO-PIE website).

Bush bans oil drilling...just kidding
Bush lifts oil drilling ban, wants Congress to act.
Totally frustrating when there are so many alternatives right in front of us.

Bio-Tag:Triclosan

©2007 COX Washington News Bureau. Story about how using antibacterial soap and hand sanitizers are actually bad for you and can lead to you being more prone to get sick.
Click here to watch video.
Wikipedia states:
Resistance concerns: An article coauthored by Dr. Stuart Levy in the August 6, 1998 issue of Nature[12] warned that triclosan's overuse could cause resistant strains of bacteria to develop, in much the same way that antibiotic-resistant bacterial strains are emerging, based on speculation that triclosan behaved like an antibiotic. Based on this speculation, in 2003, the Sunday Herald newspaper reported that some UK supermarkets and other retailers were considering phasing out products containing triclosan.
It has since been shown that the laboratory method used by Dr. Levy was not effective in predicting bacterial resistance for biocides like triclosan, based on work by Dr. Peter Gilbert in the UK, whose research is supported by Procter & Gamble [1].[13] At least seven peer-reviewed and published studies have been conducted demonstrating that triclosan is not significantly associated with bacterial resistance over the short term, including one study coauthored by Dr. Levy, published in August of 2004 in Antimicrobial Agents and Chemotherapy.[14]
Some level of triclosan resistance can occur in some microorganisms, but the larger concern is with the potential for cross-resistance or co-resistance to other antimicrobials. Studies investigating this possibility have been limited.[15]
Health concerns:Reports have suggested that triclosan can combine with chlorine in tap water to form chloroform gas,[16] which the United States Environmental Protection Agency classifies as a probable human carcinogen. As a result, triclosan was the target of a UK cancer alert, even though the study showed that the amount of chloroform generated was less than amounts often present in chlorinated drinking waters.
Triclosan reacts with the free chlorine in tap water to also produce lesser amounts of other compounds, like 2,4-dichlorophenol.[16] Most of these intermediates convert into dioxins upon exposure to UV radiation (from the sun or other sources). Although small amounts of dioxins are produced, there is a great deal of concern over this effect because dioxins are extremely toxic and are very potent endocrine disruptors. They are also chemically very stable, so that they are eliminated from the body very slowly (they can bioaccumulate to dangerous levels), and they persist in the environment for a very long time.
Triclosan is chemically somewhat similar to the dioxin class of compounds. Its production leads to small amounts of residual polychlorinated dioxins, and polychlorinated furans which are contained in small amounts, in the products that are using it.
A 2006 study concluded that low doses of triclosan act as an endocrine disruptor in the North American bullfrog.[17] The hypothesis proposed is that triclosan blocks the metabolism of thyroid hormone, because it chemically mimics thyroid hormone, and binds to the hormone receptor sites, blocking them, so that normal hormones cannot be utilized. Triclosan has also been found in both the bile of fish living downstream from waste water processing plants and in human breast milk.[18] The negative effects of Triclosan on the environment and its questionable benefits in toothpastes[19] has led to the Swedish Naturskyddsföreningen to recommend not using triclosan in toothpaste.[20]
Triclosan is used in many common household products including Clearasil Daily Face Wash, Dentyl mouthwash, Dawn, the Colgate Total range, Crest Cavity Protection, Softsoap, Dial, Right Guard deodorant, Sensodyne Total Care, Old Spice and Mentadent.
At this time, in the United States, manufacturers of products containing triclosan must say so somewhere on the label.
The ADA (American Dental Association) published a response to the concerns stemming from the Virginia Tech study stating that Triclosan in toothpaste is not relevant.
In one study, recently accepted for publication in the journal Environmental Health Perspectives and made available online, Isaac Pessah, PhD, director of the U.C. Davis Children's Center for Environmental Health, looked at how triclosan may affect the brain. Pessah's test-tube study found that the chemical attached itself to special "receptor" molecules on the surface of cells. This raises calcium levels inside the cell. Cells overloaded with calcium get overexcited. In the brain, these overexcited cells may burn out neural circuits, which could lead to an imbalance that affects mental development. Some people may carry a mutated gene that makes it easier for triclosan to attach to their cells. That could make them more vulnerable to any effects triclosan may cause.[21]

Bio-Tag: Fluoride
The Senior Vice President of the EPA Headquarters Union discusses the dangers of fluoride in our drinking water. For more information about fluoride go to: http://www.fluoridealert.org
Here is the site conclusion:
"When it comes to controversies surrounding toxic chemicals, invested interests traditionally do their very best to discount animal studies and quibble with epidemiological findings. In the past, political pressures have led government agencies to drag their feet on regulating asbestos, benzene, DDT, PCBs, tetraethyl lead, tobacco and dioxins. With fluoridation we have had a fifty year delay. Unfortunately, because government officials have put so much of their credibility on the line defending fluoridation, and because of the huge liabilities waiting in the wings if they admit that fluoridation has caused an increase in hip fracture, arthritis, bone cancer, brain disorders or thyroid problems, it will be very difficult for them to speak honestly and openly about the issue. But they must, not only to protect millions of people from unnecessary harm, but to protect the notion that, at its core, public health policy must be based on sound science not political expediency. They have a tool with which to do this: it's called the Precautionary Principle. Simply put, this says: if in doubt leave it out. This is what most European countries have done and their children's teeth have not suffered, while their public's trust has been strengthened.
It is like a question from a Kafka play. Just how much doubt is needed on just one of the health concerns identified above, to override a benefit, which when quantified in the largest survey ever conducted in the US, amounts to less than one tooth surface (out of 128) in a child's mouth?
For those who would call for further studies, I say fine. Take the fluoride out of the water first and then conduct all the studies you want. This folly must end without further delay."

Bio-Tag: VOCs
Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOCs are emitted by a wide array of products numbering in the thousands. Examples include: paints and lacquers, paint strippers, cleaning supplies, pesticides, building materials and furnishings, office equipment such as copiers and printers, correction fluids and carbonless copy paper, graphics and craft materials including glues and adhesives, permanent markers, and photographic solutions.
Organic chemicals are widely used as ingredients in household products. Paints, varnishes, and wax all contain organic solvents, as do many cleaning, disinfecting, cosmetic, degreasing, and hobby products. Fuels are made up of organic chemicals. All of these products can release organic compounds while you are using them, and, to some degree, when they are stored.
EPA's Total Exposure Assessment Methodology (TEAM) studies found levels of about a dozen common organic pollutants to be 2 to 5 times higher inside homes than outside, regardless of whether the homes were located in rural or highly industrial areas. Additional TEAM studies indicate that while people are using products containing organic chemicals, they can expose themselves and others to very high pollutant levels, and elevated concentrations can persist in the air long after the activity is completed....Eye, nose, and throat irritation; headaches, loss of coordination, nausea; damage to liver, kidney, and central nervous system. Some organics can cause cancer in animals; some are suspected or known to cause cancer in humans. Key signs or symptoms associated with exposure to VOCs include conjunctival irritation, nose and throat discomfort, headache, allergic skin reaction, dyspnea, declines in serum cholinesterase levels, nausea, emesis, epistaxis, fatigue, dizziness.
The ability of organic chemicals to cause health effects varies greatly from those that are highly toxic, to those with no known health effect. As with other pollutants, the extent and nature of the health effect will depend on many factors including level of exposure and length of time exposed. Eye and respiratory tract irritation, headaches, dizziness, visual disorders, and memory impairment are among the immediate symptoms that some people have experienced soon after exposure to some organics. At present, not much is known about what health effects occur from the levels of organics usually found in homes. Many organic compounds are known to cause cancer in animals; some are suspected of causing, or are known to cause, cancer in humans.

Bio-Tag: Lead
via youtube
Recently covered in the news, massive recalls of toys and baby products have raised the concerns of parents everywhere. Dr. Philip J. Landrigan of Mount Sinai's Children's Environmental Health Center talks on lead in toys from China giving parents practical advice on how they can protect their children and themselves.
Lead in toys has become a major problem in the USA. Lead-painted trains, lead-painted dolls and lead-contaminated plastic lunch boxes imported from China and other nations have become a major new threat to the health of American children. This is a very serious issue. Tens of thousands of children have been placed at risk of lead exposure this year because of contaminated imports. Millions of toys have been recalled. This situation reflects the grave weakness of the U.S. Consumer Product Safety Commission and the lack of federal controls on imported toys.
What can parents do? Most importantly, parents should avoid all painted toys this holiday season. Also they should avoid brightly colored plastic toys, because some of them have been shown to contain high levels of lead. Our recommended toys this year are:
• unpainted wooden toys
• sports equipment such as balls and gloves
• books
Parents should consider writing letters or sending emails to their Senators, Congressional representatives, state and local officials, and the White House to complain about the current situation. It is simply not right that this country should allow the entry of millions of dangerous toys in the weeks before the holidays.
