Comments to Emails between Steve Tvedten, and Scott Dideon, pesticide guy

[ Site Map ] [ Back to Emails ]

Everyone,

This might even get interesting! If anyone wants to comment on the fact Dr. Scott Dideon told Linda that he does not know anyone who was ever poisoned, you now have his e-mail address. My Mother died at 1:20 PM today, 1/4/01, so she can no longer write him. But by G-d, I can, and I was also POISONED by the "industry" he wants to promote! Truth is not something you sell, it is something you are willing to die for. 

Steve


Dear Scott,

 

I have received some of your correspondence with Steve Tvedten.  It appears that you have not been introduced to the walking wounded - those of us who, for various reasons, have bodies that cannot withstand the foreign chemicals in pesticides.  I say "walking wounded" yet some of us have been or still are wheelchair-bound.  We are in all walks of life.  We have many different levels of education, many different religious beliefs, and used to practice many different professions before pesticide poisoning stole our lives.

So, let me introduce myself.  Before pesticide poisoning (BPP), I was a minister, had founded a church, and was doing workshops in jails and prisons for former substance abusers.  Working with two other churches, we were putting together a non-profit to help the folks in the welfare to workfare programs learn how to be successful in making the transition our government was insisting they make.

BPP, I had no idea RoundUp herbicide existed.  I refused to use things like that on general principals because I care about the legacy we are leaving future generations, and because a 1994 allergy test showed I had an allergy to organophosphates.

Unfortunately, the lawn maintenance contractor was not as concerned about his legacy.  He inundated our former townhouse community with Roundup without telling anyone.  I worked out in our back yard the following day, and chewed on some of the vegetation that had been sprayed.  Our cat ate some of the grass that had been sprayed.

To make a long story short, our cat died from this exposure.  I had to go on oxygen round the clock just to be able to walk because of it.  Between April and late July 1996, I sustained four more exposures via inhalation of the drift of the RoundUp used in our former community.  After the last exposure, I could no longer stand or walk without assistance.  I was bed-bound and in a wheelchair for the next four months.  The first time I was told I was dying was because the RoundUp had caused my pseudocholinesterase to drop precipitously.  Fortunately, I found a researcher who had found a way to reverse pseudocholinesterase loss in rats, but not before calling all over the US and being told there was no way to help me.  I was also told that RoundUp could not possible do this.

A wonderful EI doctor helped me beat the Grim Reaper the second time I was at his doorstep.  From her testing I have learned that RouundUp caused Toxic Encephalopathy, Seizure Disorder, Toxin Acquired Porphyria, Mastocytosis, Wilson's Syndrome, Impaired Tissue Perfusion, chemical sensitivity to petrochemicals, and damage to my liver's P-450 enzyme system.  I have now been on oxygen since 1996 when this happened.

Getting help for Roundup poisoning has been an uphill battle because of the misinformation put out by its manufacturer.  Even the initial registration for the product was fraudulent.  It has also been advertised by its manufacturer as "safe as table salt."  You would not believe how many people, when I was calling to find help for RoundUp poisoning, offered to drink it to prove to me how "safe" it supposedly is.  (They would be singing that song in a different choir if they had actually done it.)

I recently wrote a paper on all that I had learned about RoundUp since my experience with it turned my life upside down.  FYI, you will find it below, along with some new information that shows that RoundUp is an endocrine disruptor.

I am not an unusual member of the "walking wounded."  I was more susceptible to pesticide poisoning because I had a chronic disease when it happened, and because I was taking Axid and estrogen.  But, I am by no means an isolated incidence.  You might also find some good information at www.home1.gte.net/revision/disposable.htm - another article that shows that over 50% of our population is in the category of being more susceptible to pesticide poisoning.  It is a Find law document that gets a lot of traffic.

I think what Steve was attempting to bring to your attention is the fact that pesticides kill more than bugs or weeds, and seriously harm a lot of people.  You said in your post that you are a scientist, so I would assume you are open to new information.  If that is the case, you will probably enjoy the articles below.  If not (a closed mind gathers no facts), then just delete the post.

Steve Tvedten has a lot of credibility with a lot of people. He is not the only former pesticide applicator I know who was harmed by the products he used, but he is certainly one of the most knowledgeable when it comes to IPM.

Peace and Light

Suzanne Fisher

The Toxicity of RoundUp Herbicide by S. Suzanne Fisher

RoundUp Herbicide has been touted by its maker, Monsanto, as safe and environmentally friendly.  As such, it has become the most popular herbicide in use today.  Advertising by Monsanto has led the public to believe that RoundUp is "safe as table salt," a phrase used quite often by its proponents to describe it.

Studies used for RoundUp's initial registration were fraudulent. There is no indication that these studies have been replaced with other, more valid, studies.  The public perception of RoundUp as safe, environmentally friendly, and no more harmful than table salt has impeded the normal scientific study to which a pesticide would normally be subjected.  Research grants have been concentrated in the areas of pesticides perceived to be more detrimental to humans.

New York State's Attorney General has sued Monsanto for claiming that RoundUp is "safe" and "environmentally friendly."  This suit ended in a settlement with Monsanto in which Monsanto agreed to cease and desist from using these terms in advertising RoundUp in the state of New York.  Monsanto, while not admitting any wrongdoing, paid the state of New York $250,000 in settlement of this suit.  When Monsanto violated the first settlement agreement by advertising within New York that RoundUp is "safe," a second agreement was negotiated.

Most of the studies identifying RoundUp's true toxicity are recent, and certain areas of RoundUp's toxicity have yet to be thoroughly studied.  Case law involving RoundUp victims is almost non-existent due to this lack of scientific information with which to prove causation.  It is for these reasons that it is important to also look to anecdotal information about RoundUp's toxicity to humans in order to develop a full picture of the symptomology it causes.

The narrative below offers the following information about RoundUp Herbicide:

I. Ingredients in RoundUp
II. Anecdotal evidence of RoundUp's toxicity to humans
III. Research evidence of RoundUp's toxicity to humans
IV. Additional factors affecting the toxicity of RoundUp

I.      RoundUp herbicide by Monsanto contains the following ingredients:

A.      In a letter forwarded to Northwest Coalition for Alternatives to Pesticides, Monsanto identified RoundUp's ingredients as:

1. Isopropylamine salt of glyphosate (active ingredient)
2. Water
3. The ethoxylated tallowamine surfactant
4. Related organic acids of glyphosate
5. Excess isopropylamine

B.      According to the US Environmental Protection Agency in a letter dated April 30, 1999, in response to a Freedom of Information Request, the following inert ingredients are in RoundUp Super Concentrate Weed & Grass Killer:

1. Polyoxyethylene alkylamine (CAS #61791-2)
2.   Water (CAS #7732-18-5)
3. FD&C Blue No. 1 (CAS #3844-45-9)

C.      David H. Monroe, and Industrial and Environmental Toxicologist, stated in an October 16, 1989 letter to the National Campaign Against the Misuse of Pesticides (NCAMP) that most polyalkoxylated surfactants such as the polyoxyethylene alkylamine in RoundUp are contaminated with 1,4-dioxane.  A study done by Monroe on Vision, a glyphosate product by Monsanto, revealed that it contained 1,4-dioxane at a level of 350 ppm.

(Monroe D, 1989.  Letter to NCAMP.)

1,4-dioxane is carcinogenic, and is known to damage the liver, kidney, brain and lungs.

II.     Anecdotal evidence of RoundUp's toxicity to humans:

A.      From July 1987 edition of The Progressive, and article entitled 'Weed Killer':

Eduardo Neaves, a 12-year-old, went swimming in a canal in Coral Gables, Florida that was contaminated with four times the recommended amount of RoundUp herbicide. The child became completely paralyzed, and five years after the incident suffers residual nervous system damage.

The EPA, according to this article, in 1985 reported on the case of a 59-year-old woman in Tennessee who has suffered central nervous system damage after exposure to RoundUp.

Monsanto's original neurotoxicity studies on RoundUp were ruled invalid by the EPA due to "extensive gaps in the raw data supporting study findings and conclusions.  There has been no requirement for a new study on the neurotoxicity of RoundUp.

Other persons have experienced swelling in legs, arms, and joints after exposure to RoundUp.

Still others have experienced the following after exposures to RoundUp: central nervous system damage,  body swelling in legs, face and abdomen. Other RoundUp overexposure symptoms reported include visual, hearing, taste, and smell disturbances; balance disorder; body-wide muscle twitches and tics; seizure disorder; muscle paralysis; peripheral neuropathy; loss of gross motor skills and loss of fine motor skills.

B.      From a paper entitled 'Glyphosate' prepared by Pesticide Action Network - Asia and Pacific

"Glyphosate is the most frequent cause of complaints and poisoning incidents recorded by the Health and Safety Executive in the UK." (Pesticides Trust 1996)

Dr. Ricky Goring of New Zealand estimates that 1 in 20 people in New Zealand are sensitive to glyphosate, with the most common symptoms including: fatigue, headaches, spaciness, rashes, and unexplained drops in blood pressure.  Dr. Gorringe states these symptoms are the result of inhalation exposures.

In 1980 the EPA reported that among 94 people reporting exposures to glyphosate in the US, "the following symptoms were noted: bronchial constriction, pleuritic chest pain and nasal congestion; blurred vision, corneal erosion, and conjunctivitis; contact dermatitis; headache; nausea, diarrhoea and abdominal pain; irritability; excessive sweating; vertigo; malaise; swelling of the extremities; and nervous system disorders."

III.    Research evidence of RoundUp's toxicity to humans 

A.      Ingestion of RoundUp has been shown to cause "irritation of the oral mucous membrane and gastrointestinal tract…pulmonary dysfunction, oliguria, metabolic acidosis, hypotension, leukocytosis and fever."

Monsanto's own toxicologist, Rebecca Tominack, participated in this study.

(Tominack RL, Yang GY, Tsai WJ, Chung HM, Deng JF, 1991.  Taiwan National Poison Center survey of glyphosate-surfactant herbicide ingestions. J Toxicol Clin Toxicol 1991; 29 (1): 91-109)

Many people report experiencing severe digestive problems related to irritation of their gastrointestinal tract after overexposure to RoundUp, limiting the foods their bodies will tolerate to a very few bland foods.

B.      Cholinesterase Inhibition of RoundUp

1.      Monsanto states that glyphosate is not a cholinesterase inhibitor. The MSDS on RoundUp also says that glyphosate is not a cholinesterase inhibitor.  Yet, glyphosate is a an organophosphorus, and the "toxic effects of organophosphorus (OP) compounds are predicated on their irreversible inhibition of acetylcholinesterase (AchE) and other serine hydrolases."

(Viragh C, Kovach IM, Pannell L, 1999. Small Molecular Products of Dealkylation in Soman-Inhibited Electric Eel Acetylcholinesterase.  American Chemical Society, June 11, 1999.)

2.      Merely saying glyohosate is not a cholinesterase inhibitor, however, does not define whether RoundUp itself in full formulation is a cholinesterase inhibitor, and there are no published studies that purport to answer this question.

In 1988, Yusuke Sawada, et al. did a study in which they concluded that the surfactant in RoundUp (POEA) is more toxic than RoundUp's main ingredient, glyphosate.  A study by Servizi et al in 1987 found that POEA is two to three times more toxic than glyphosate, and that the synergy of the two ingredients may even be more acutely toxic than the two ingredients combined.

The answer to whether RoundUp in full formulation is a cholinesterase inhibitor can only be determined by looking at anecdotal evidence such as Suzanne Fisher's experience.  Many doctors, based on Monsanto's advertising that glyphosate is not a cholinesterase inhibitor, refuse to test RoundUp poisoning victims for cholinesterase inhibition, so even anecdotal evidence is not readily available.

(Sawada Y, Nagai Y, Ueyama M, Yamamoto I, 1988. Probable toxicity of surface-active agent in commercial herbicide containing glyphosate.  Lancet. 1988 Feb 6;1(8580):299.)

(Servizi JA, Gordon RW, Martens DW, 1987. Acute toxicity of Garlon 4 and Roundup herbicides to salmon, Daphnia, and trout. Bull Environ Contam Toxicol. 1987 Jul;39(1):15-22. )

3.      An October 27, 1999 article by PANUPS (Pesticide Action Network Updates Service) offers the information that according to a European Community report on glyphosate (not released at that time), glyphosate poses a significant risk to certain beneficial insects.

(PANUPS, 1999. Glyphosate May Harm Beneficial Organisms, October 27, 1999)

In a 1993 article on organophosphate poisoning, British researcher, T. C. Marrs, indicated that "certain OPs are exploited for their anticholinesterase effects, including defoliants such as 'DEF', herbicides such as glyphosate."  The article goes on to say that the cholinergic syndrome is "caused by acetylcholinesterase inhibition."

(Marrs, TC, 1993.  Organophosphate poisoning.  Pharmacol Ther 1993; 58(1): 51-66.)

4.      An area that has yet to be explored is the impact of the degradation process for glyphosate on the serine cycle. The serine cycle plays a strong part in cholinesterase inhibition in humans.  From available research, it is easy to conclude that, while glyphosate itself might not technically be anticholinergic, the degradants of glyphosate might very well be cholinesterase inhibitors.

Glyphosate degrades into sarcosine and formaldehyde.  Formaldehyde is not only carcinogenic, but impairs the serine cycle, an important part of the human metabolic process.  According to a document on the ESTHER database, "cholinesterases are readily phosphorylated at the active site serine by a variety of organophosphorus agents (OP) and carbamates."

(www.ensam.inra.fr/cholinesterase/chem/chemInhibition2.html.  The ESTHER "Chemical Mechanism of Acetylcholinesterase Inhibition" introduction.)

(Goldberg I, Mateles RI , 1975. Growth of Pseudomonas C on C1 compounds: enzyme activities in extracts of Pseudomonas C cells grown on methanol, formaldehyde, and formate as sole carbon sources. J Bacteriol 1975 Apr;122(1):47-53)

5.      There is reported evidence of a patient who, after exposures to RoundUp, showed a depressed pseudocholinesterase. SmithKline Beecham's Normal Values reference range is 3200 - 6600.  On 6/4/96, after three major exposures to RoundUp, this patient’s pseudocholinesterase was 2887.  On 7/8/96, after an additional major exposure to RoundUp, this patient’s pseudocholinesterase was 2700.  The last reading during the period of this patient’s exposures to RoundUp was 2733 on 8/7/96.  Only with the assistance of successful drug therapy (large doses of dextromethorophan) was this reading reversed to 3586 on 10/22/96.

C.      RoundUp causes damage to the liver that inhibits the liver's ability to process toxic substances.

1.      Research subject animals injected with glyphosate evidenced a depressed function of the liver.  "Glyphosate decreased the hepatic function of cytochrome P-450 and monoxygnease activities and the intestinal activity of aryl hydrocarbon hydrolase." (Heitanen et al, 1983).  The P-450 enzyme system is one of the main body systems for detoxifying harmful chemicals.  When it becomes impaired by those same chemicals it is supposed to be detoxifying, the effects of a given chemical on the body increase dramatically.

(Heitanen, et al., 1983.  Effects of phenoxyherbicides and glyphosate on the hepatic and intestinal biotransformation activities in the rat.  Acta Pharmacol Toxicol (Copenh) 1983 Aug; 53(2):103-12.)

2.      Testing of patients suffering RoundUp overexposure has indicated damage to their P-450 enzyme system.

D.      Roundup produces significant increases in sister-chromatid exchanges (SCE), albeit in higher concentrations over those used for other pesticides.  This suggests that it should be evaluated in other genetic tests measuring mutations and chromosome aberrations, although few studies of this nature have yet been done.

1.      A 1980 study by Vigfusson and Vyse noted sister-chromatid exchanges in human lymphocytes in vitro.  This lymphocyte disturbance correlates with the swelling experienced by persons poisoned by RoundUp. (Vigfusson, N.V. and Vyse, E.R. (1980), "The effect of the pesticides, Dexon, Captan, and Roundup, on sister-chromatid exchanges in human lymphocytes in vitro". MUTATION RESEARCH, v.79 p.53-57.)

2.      William Meggs, M.D., Ph.D., School of Medicine, East Carolina University:

In patients who have been chemically injured, Meggs has noted significant lymphatic hyperplasia, lymphatic tissue that is swollen and engorged. He has also found significant cobblestoning in upper airway passages.  This represents chronic inflammation caused by lymphocytes migrating out of the blood stream and seeping into the tissues. Meggs has also noted thickening of the structure called the basement membrane, the structure on which the lining of cells that lines the interior of the nose sits.  Meggs' study also found a defect in the tight junctions (the joining of cells together) and a proliferation of nerve fibers.

"Chemicals bind to receptors on nerve fibers and produce something called neurogenic inflammation. These chemicals bind to these receptors and cause the release of potent substances that produce inflammation in tissue.

When chemicals bind to nerve fibers, they can produce inflammation.  Inflammation, in turn, produces other changes in the tissue, and it brings in these lymphocytes. We believe that inflammation causes these barrier cells to open up and sometimes even come off the basement membrane.  Below the basement membrane is the nerve fibers, so we have a process whereby a chemical exposure will damage the lining of the nose.

What happens is people have a large chemical exposure, they breathe in noxious chemicals, and this damages the epithelium.  This huge exposure is able to penetrate this barrier we have between the chemicals we breathe in and these nerve cells beneath the lining layer that react to chemicals by producing inflammation. The inflammation, in turn, produces substances that cause further damage to the lining cell, and actually produce the substances which cause the tight junctions between these cells to open up.  In some cases the cells actually come off and just leave these bare nerves exposed.  Once you have the bare nerves exposed, low levels of chemicals that we all experience every day are enough to produce inflammation which in turn keeps the epithelium damaged."

E.      RoundUp was found to cause significant DNA damage to erythrocytes (red blood cells) in a study done in 1997 by Clements, Ralph and Petras.  RoundUp's surfactant, POEA, is known to cause haemolysis.

(Clements C, Ralph S, Pertas M, 1997.  Genotoxicity of select herbicides in Rana catesbeiana tadpoles using the alkaline single-cell gel DNA electrophoresis (comet) assay. Environ Mol Mutagen 1997; 29(3):277-288.)

(Sawada Y, Nagai Y, Ueyama M, Yamamoto I, 1988. Probable toxicity of surface-active agent in commercial herbicide containing glyphosate.  Lancet. 1988 Feb 6;1(8580):299.)

1.      In haemolysis, hemoglobin leaks from the red blood cells, leaving them unable to transport sufficient supplies of oxygen to the body's tissues.

2.      The chest pains, difficulty breathing, and impaired cognitive skills reported by persons who have sustained RoundUp poisoning also point to impairment of the blood's oxygen transport system, hemoglobin, as being responsible for these symptoms.  This impairment of the erythrocytes' ability to deliver adequate oxygen to both brain and body results in impaired tissue perfusion and hypoxia.

3.      "The brain is particularly vulnerable to hypoxia, and exposure to toxins that interfere with the intake, transport and utilization of oxygen provoke rapid and major neuronal damage.  Compounds crossing the blood-brain barrier may induce both general and extremely localized neurotoxic effects."

(Kyvik KR, Morn BE, 1995.  Environmental poisons and the nervous system.  Tidsskr  Nor Laegeforen 1995.  June 10; 115(15):1834-8.)

4.      According to both the EPA and the World Health Organization in 1993 and 1994, glyphosate appears to mimic adrenaline.  This would explain the sleeping problems encountered by many persons exposed to RoundUp, as for them, cortisol appears to no longer be properly regulated by their bodies' adrenal glands.

(US EPA, 1993. EPA Reregistration Eligibility Document, Glyphosate, Office of Prevention, Pesticides and Toxic Substances, Washington, D.C., September 1993.)

(IPCS, 1994.  Environmental health criteria 159: Glyphosate.  International Programme of Chemical Safety, World Health Organization, Geneva.)

5.      The paralytic seizures that began for one patient in August 1996, right after the patient’s last exposure to RoundUp herbicide, involve impaired erythrocytes.  In a blood test done in December 1996, five months after the patient’s exposures to RoundUp herbicide, over 90 per cent of this patient’s erythrocytes were damaged, showing up as either flat or misshapen.  This patient also experienced reduced cognitive capacities, and a vast assortment of neurological symptoms since sustaining RoundUp overexposure.  The first year and a half after the patient’s exposures to RoundUp, this individual got between 0 - 2 hours of sleep per night.

IV.     Additional factors affecting the toxicity of RoundUp

A.      From http://www.safe2use.com/ca-ipm/00-03-02.htm. 

Pesticides and Deadly Tagamet Synergism by Steve Tvedten (former pesticide applicator).

1.      Tagamet and other H-2 Blockers such as Axid and Pepcid, all now readily available over the counter, increase the vulnerability of persons taking these drugs to pesticide poisoning.  Taken by millions, these drugs vie for the same detoxification pathways in the body as pesticides do, making people taking the drugs more susceptible to the devastating effects of pesticide poisoning.

B.       Estrogen can also an important factor in the severity of the impact RoundUp has on people.

1.      Iris Bell, M.D., Ph. D., University of Arizona Health Sciences Center:

"In the sensitization process, we know that female animals are more likely to sensitize than are male animals, and, in research that has been done, picking apart the hormonal factors that may contribute, they found that a higher ratio of estrogen to progesterone seems to make the female animal more vulnerable for sensitization.  Testosterone appears to protect the male animal."

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

RoundUp works in plants by damaging the P-450 enzyme system.  Its effect on me was quite similar in that it damaged my liver's detoxification system.  I could never prove the hormonal disruption caused by RoundUp until now even though I suffered the consequences of it.

This is the first study I have seen that addresses the fact that RoundUp damages the P-450 enzyme system in humans also.  It goes even further, and says, "StAR protein mediates the rate-limiting and acutely regulated step in steroidogenesis, the transfer of cholesterol from the outer to the inner mitochondrial membrane where the cytochrome P450 side chain cleavage (P450scc) enzyme initiates the synthesis of all steroid hormones."

AND

"Roundup inhibited steroidogenesis by disrupting StAR protein expression, further demonstrating the susceptibility of StAR to environmental pollutants."

(See below also a definition of steroid hormone.)

***************************

My Conclusion: RoundUp has just been conclusively identified as an Endocrine Disruptor, and as such needs to be banned.
