CHEMICALS & PESTICIDES


LATEST MATERIAL PUBLISHED DURING THE WEEK
Updated SEPTEMBER, 26th, 2013


  After the failure of pharmaceutical monotherapies the world rediscovers medicinal plants or the miraculous Artemisia family: by Dr. Pierre Lutgen, Luxembourg - In the absence of efficient primary health care systems, traditional medicine occupies a central place in the provision of health care, especially among rural communities of developing countries. According to WHO 80% of the world population are relying on herbal medicine. This is attributable to accessibility, reliability and affordability. The number of scientific papers related to plants is exploding. (26-sept-2012)

Artemisia annua tea stronger than chloroquine: Recent results obtained at the AlQuds University in partnership with IFBV-BELHERB from Luxembourg show that freshly prepared infusion of Artemisia annua is stronger than chloroquine in the inhibition of beta-hematin (hemozoin) formation. In the infected erythrocyte the malaria parasite generates large quantities of toxic heme which it has to render innocuous by polymerizing it into hemozoin. The mechanism of quinine and all its derivates, chloroquine, amodiaquine operates by inhibiting this hemozoin crystallization. (12-august-2012)

A "vaccine"against malaria from Africa: ARTAVOL: by Dr. Pierre Lutgen, Luxembourg. Since 5 years ago a group of scientists at the Ministry of Health of Uganda was working on plant extracts which might have a prophylactic effect against malaria. Since 12 months ago a product is available in the pharmacies of Uganda. The product has been released after clinical and community trials over 3 years which have demonstrated that if taken regularly during one year it renders a person immune against malaria. It also reduced the asymptomatic malaria cases in an adult population by 60%. (16-may-2012)

Toxic Effects of Artemisinine Derivatives at High Doses: Some recent research, mostly in relation with the resistance to ACT pills and/or artesunate injections, has highlighted serious secundary health effects at the doses prescribed by WHO. Fears of emerging artemisinine resistance in western Cambodia have promoted a series of clinical trials investigating if resistance can be overcome by increasing doses of drug. (16-may-2012)

The essential role of sulfated polysaccharides in artemisia annua tea infusion: So far the presence of polysaccharides in Artemisia annua has been barely covered in the scientific literature. The reason may be that they are only soluble in water and most of the Artemisia extracts for research are obtained by organic solvents. Polysaccharides are polymeric carbohydrates of high molecular weight. They have probably been overlooked in the research on Artemisia annua. (31-october-2011)

Artemisia annua tea: prophylaxis against malaria: In recent years several NGO's, like IFBV, promote artemisia annua tea in tropical countries. This plant has excellent therapeutical properties against malaria, as demonstrated by several clinical trials. Recently a scientific paper confirmed the prophylactic effect against malaria on several hundred farmers in Uganda. (PE Ogwang et al., Brit J Pharm Res ISSN 2231-2919). A medical team at Luxembourg had already found in 2010 that Artemisia annua tea activates the lymphocytes in human blood, but only if the tea was poor in artemisinine. (26-august-2011)

Artemisia annua prevents the transmission of malaria from man to mosquito: The killing effect of artemisinin on gametocytes is known since twenty years and was first mentioned in in vitro trials at the John Hopkins University. These results were confirmed in 1993 by research teams in China and India and mentioned in the document WHO/MAL/ 98.1086. The Malaria Journal published a review article [1] in 2008 describing similar studies involving a few thousand people in several countries. (27-june-2011)

Bactericidal properties of Artemisia annua tea and dosimetry of artemisinin in water by fluorescence under UV light.: paper presented at the International Conference « Maladies tropicales, aspects humanitaires et économiques », Luxembourg, June 3-4 2008, giving results of tests and research on Artemisia annua and its healing effect on malaria. (11-july-2008)

Is the Concept of a Linear Relationship Between Dose and Effect Still a Valid Model for Assessing Risks Related to Low Doses of Carcinogens - the DDT Example.: by Dr. William Hazeltine, - For Presentation to a Seminar Sponsored by the International Center for Scientific Ecology, May 10, 1993, at Paris, France. (1-october-2006)

DDT - A Weapon of Mass Survival: by Steven Milloy - The U.S. Government has finally begun to reverse policy on the insecticide DDT. Let's hope that this policy shift represents the beginning of the end of what can only be called a crime against humanity: the decades-old withholding of the world's most effective anti-malarial weapon from billions of adults and children at risk of dying from the disease. (5-MAY-2006)

ACSH Holiday Dinner Menu: Full of carcinogens - what did you expect? And they are all natural! Will they harm you? Of course not -ingested at the naturally ocurring dose in the environment. (18-DEC-2005)

It's the alcohol!: Virtually everyone "knows" that red wine is the best type of alcoholic beverage to consume if you're concerned about health. After all, the French eat lots of cheese and other high fat foods, yet their rate of heart disease is lower than ours. But, as with much other common knowledge, it's simply not true. There's no magic to red wine. (8-APR-2005)

The Growing Public Anxiety About Lung Cancer : Dr. Elizabeth Whelan, ACSH. Ever since ABC News anchor Peter Jennings announced last week that he had been diagnosed with lung cancer, we have observed an increased interest in the disease--particularly the probability of it occurring in former smokers.  We have spoken with dozens of former smokers and read reports of anxiety in this group, and, drawing on the American Council on Science and Health's past research, we offer facts and advice on lung cancer.  Our advice is tailored to three different groups: a) ex-smokers, b) current smokers, and c) non-smokers who are candidates to take up the habit. (8-APR-2005)

Breast Cancer: News is Too Good: Editorial by Dr. Elizabeth Whelan, ACSH. "What if there was growing evidence that an already-existing drug, taken daily, might dramatically reduce the risk of breast cancer? Shouldn't that be more newsworthy than fund-raising walkathons done in the quixotic pursuit of a simple cure? More noteworthy than the latest lab test which classifies an environmental chemical as a rodent carcinogen?" - There is such a drug. Read on. (8-APR-2005)

Buzzing in the bush: (By WC Douglass Daily Dose April 23, 2004) - Sometimes, I hate being right. It was nearly 2 years ago when I first wrote about the westward spread of the West Nile virus in this country after its initial 1999 New York outbreak - and about how our green-leaning government refuses to employ the simplest, safest, cheapest and most effective weapon against it (and against all mosquito-borne illnesses, for that matter), DDT.(18-APR-04)

What the world needs now is DDT: Article by Tina Rosenberg, published in The New Times magazine edition of April 11th, 2004. Finally, common sense seems to be returning to journalists. We would have never thought we'd published here a The New York article - and be praising it. (18-APR-04)

Bring Back DDT - and Science With It!: full text of Editorial from Summer 2002 issue by Marjorie Mazel Hecht: The 1972 U.S. ban on DDT is responsible for a genocide 10 times larger than that for which we sent Nazis to the gallows at Nuremberg. It is also responsible for a menticide which has already condemned one entire generation to a dark age of anti-science ignorance, and is now infecting a new one.

Mosquitoes, DDT, and Human Health: J. Gordon Edwards, a leading entomologist, describes the death and suffering caused by insect-borne diseases, and tells why we must bring back DDT.

To Control Malaria, We Need DDT!: The following is adapted from a presentation by Donald R. Roberts, Ph.D., Professor of Tropical Public Health at the Uniformed Services University of the Health Sciences in Bethesda, Maryland. Roberts's talk, titled "DDT and Malaria Control: Past, Present, and Future," was given to a conference sponsored by Accuracy in Media in Washington, D.C., in October 2002.

The Medical Effects of Marijuana on the Brain: New research on marijuana confirms that it damage cognitive functioning. Pot legalization would spread this disabilty. The marijuana plant contains more than 400 chemical compounds, of which 60 are cannabinoids – psychoactive compounds that can be extracted from the cannabis plant, or produced within the body after ingestion and metabolism of cannabis. Here, we analyze the ramifications of some of the most important scientific discoveries about marijuana and its negative impact on the brain.

Malaria: The Killer That Could Have Been Conquered: Malaria, which could have been conquered 20 years ago, is still the single most important tropical disease and a major obstacle to the economic and social development of vast areas of the world. Before the discovery of the pesticide DDT in the early 1940s, there were at least 300 million cases in the world annually, and more than 3 million of those who were stricken died each year. Thanks to the pesticide DI3T, millions of lives were saved from malaria's grip in the years immediately following World War II. There was hope that DDT would bring an end to this mass killer, once and for all. (by Prof. J. Gordon Edwards)

The Lies of Rachel Carson: (by Prof. J. Gordon Edwards) As I neared the middle of the book, the feeling grew in my mind that Rachel Carson was really playing loose with the facts and was also deliberately wording many sentences in such a way as to make them imply certain things without actually saying them. She was carefully omitting everything that failed to support her thesis that pesticides were bad, that industry was bad, and that any scientists who did not support her views were bad. I then took notice of her bibliography and realized that it was filled with references from very unscientific sources. Also, each reference was cited separately each time it appeared in the book, thus producing an impressive array of "references" even though not many different sources were actually cited. I began to lose confidence in Rachel Carson, even though I thought that as an ecologist I really should continue to support her.



New material next week!




  What is Malaria? : (by Prof. J. Gordon Edwards) An excellent and comprehensive article on what is malaria, the medical and health problems malaria posses to people in tropical areas, and the future of this disease.

  Does Nature Know Best?: (by Dr. William Hazeltine) "Another often-used term is "Nature Knows Best," but this phrase is also misleading. Nature has no safe or kind meaning. Nature is not benign; it operates under a harsh set of realities, such as eat or be eaten, the weak are the first to die, and high rates of reproduction are necessary for survival in areas of high death rates."

EPA's Rol: Politics, Not Science: (by Prof. J. Gordon Edwards) Why is all of this so important? Simply because it reveals the nature of the leadership and the methods of operation of the powerful EPA. Can responsible public health, agriculture, or industry long survive under an EPA whose capricious zeal so greatly surpasses its expertise?

  Holiday Dinner Full of Carcinogens: November, 2001. The traditional American holiday meal, which typically includes mushroom soup, roast turkey, potatoes, green salad, fruit and pumpkin pie, is really a chemical feast of toxins and carcinogens—all courtesy of Mother Nature. That was the conclusion of the American Council on Science and Health (ACSH) in its annual "Holiday Dinner Menu". Happily, the scientists at ACSH assure us that these natural chemicals are safe. ACSH's Holiday Dinner Menu highlights the chemical carcinogens that Mother Nature has put in our food to make the point that the mere presence of a supposed cancer-causing agent—whether natural or synthetic—does not necessarily make that food dangerous.

Nature's Chemicals and Synthetic Chemicals: Comparative Toxicology: Scientific study by Drs. Bruce Ames, Margie Profet and Lois Swirsky Gold, from the University of California, at Berkeley: a report to "Proceedings of the US National Acadamy of Sciences"-- ABSTRACT: "The toxicology of synthetic chemicals is compared to that of natural chemicals, which represent the vast bulk of the chemicals to which humans are exposed. It is argued that animals have a broad array of inducible general defenses to combat the changing array of toxic chemicals in plant food (nature's pesticides) and that these defenses are effective against both natural and synthetic toxins. Synthetic toxins such as dioxin are compared to naturai chemicals, such as indole rarbinol (in broccoli) and alcohol. Trade-offs between synthetic and natural pesticides are discussed. The finding that in high dose tests a high proportion of both natural and synthetic chemicals are carcinogens, mutagens, teratogens, and clastogens (30 to 50% for each group) undermines current regulatory efforts to protect public health from synthetic chemicals based on these tests." 62 references and 5 Tables included.

Tables of the study by Dr. Bruce Ames:
Table1: Review of epidemiological studies on cancer, showing protection by comparison of fruits
           and vegetables.
Table 2: Carcinogenicity of natural plants pesticides tested for rodents
            (Fungal toxins are not included)
Table 3: Carcinogenicity in rodents of natural chemicals in roasted coffe
Table 4: Proportion of chemical evaluated as carcinogenics
Table 5: Ranking Possible Carcinogenic Hazards from Average U.S. Exposures

Natural vs. Synthetic Chemical Pesticides: The effort to eliminate synthetic pesticides because of unsubstantiated fears about residues in food will make fruits and vegetables more expensive, decrease consumption, and thus increase cancer rates. The levels of synthetic pesticide residues are trivial in comparison to natural chemicals, and thus their potential for cancer causation is extremely low.

Silent Spring and The Betrayal of Environmentalism: (By Dr. Thomas H. Jukes) If an environmentalist organization wishes to protect human health, its priorities should be set. The biggest threats are from tobacco, alcohol, and drug abuse. Instead, as a result of Rachel Carson's 1962 book, Silent Spring major environmentalist groups are preoccupied with the non-problem of pesticide residues in foods, when actually the use of pesticides increases the supply of health-improving fruits and vegetables. Carson's Silent Spring presents an account so dramatically contrary to facts, so eloquently and persuasively, and so permanently influential that its negative impact is difficult to overestimate.

The Case for DDT: What do you do when a dreaded environmental pollutant saves lives? The pesticide DDT has a long and checkered history. Today, it evokes particularly contentious argument. Though environmentalists have come to demand this poison's elimination from the face of the Earth, some tropical-disease specialists laud DDT as an irreplaceable weapon in their fight against malaria. Which view prevails may be a life-and-death matter for nearly a half-billion people.

DDT: FAQs and FACTS : everything you need to know about DDT, why it was banned, the fraud behind the ban, and the disastrous consequences it inflicted upon people in the Third World.

The Alar Scare: ten years later.
On the tenth anniversary of the onset of the "Great Apple Scare," the American Council on Science and Health (ACSH) recalls the events that led to a nation-wide hysteria.

Perchlorate in Drinking Water: Scientific Collaboration in Defining Safety Since the mid-1990s, there has been an increasing amount of research effort aimed at evaluating the potential human health risk of perchlorate (ClO4) because of its presence at trace levels in some water systems. Concern over potential effects on the thyroid gland in humans from perchlorate exposure and whether environmental levels pose a risk to human health have surfaced recently. In response to this concern, a broad collaborative effort spanning both private and government sectors has been engaged in extensive toxicological testing of perchlorate to add to our knowledge about how and under what exposure conditions perchlorate may cause effects in laboratory animals and in humans. The collaboration between the U.S. Environmental Protection Agency (EPA), the Department of Defense (Air Force) and an inter-industry Perchlorate Study Group (PSG) is unique in its focus on development of state-of-the art science for accurately determining what constitutes a safe level for humans.

How to Understand Scientific Studies and Epidemiology: This article takes a look at the basic rules of epidemiology. Some of those rules look really basic, even simple, but you'd be surprised at the trouble some people have with them. Learn how not to be misguided by biased or dishonest statistics in studies pretending to create false alarms and scares about imaginaries "clusters" of disease among the population.

Chemical toxicity: A matter of massive miscalculation: Due to the multiplicity of chemicals and our limited understanding of how the human organism works, questions often arise as to whether an adverse effect has actually occurred, even if some biological change can be detected. Toxicology can provide answers to many questions we wish to address, but those answers must be looked at cautiously. We should not use these data to develop a false sense of what we know and unrealistic expectations for what our actions can accomplish.

The Mediterranean Diet: "Since the beginning of the 70's Americans have dropped their consumption of fat to about 34% of their calories from fat, down from over 40% beforehand. The incidence of heart disease does not seem to have declined, as a 10-year study reported in the New England Journal of Medicine in 1998. Nonetheless, the treatment of heart disease has improved enormously - with more than 5.4 million heart-related procedures compared with 1.2 million in l979. This may provide the questionable impression that it is dietary change which is responsible for improved coronary experience." Is wine and olive oil good for your health? Find out here.

CHRISTINE WHITMAN'S FOLLY: On December 4, the Environmental Protection Agency, now headed by Christine Todd Whitman, ordered General Electric to dredge or pay for the dredging of 40 miles of the upper Hudson River at an estimated cost of half a billion dollars. The purpose of the dredging is to remove some 2.65 million cubic yards of sediment containing PCBs, one of the first targets in the chemophobe craze that swept America in the 1970s.

Environmental and Health Costs of Regulations: Is there anyone opposed to a safe working environment? Is there someone who likes dirty air, polluted water, or an unsafe car? Surely not. Unfortunately, both print and electronic media have confused "safe" as being the same as "risk free." This confusion is perpetuated in the public and there is a constituency (in fact, an industry) that benefits from the retention or enhancement of such a confusion.

FUMENTO ON ASBESTOS The greatly exaggerated asbestos issue is covered here. But he has not yet written an article on the certain probability that if asbstos had not been banned, the Twin Towers could could have not collapsed.:

MICHAEL FUMENTO ON DIOXIN AND AGENT ORANGE A great hoax of olddata clearly exposed.
