The world we live in today has become almost totally chemical oriented.
Most of the man made chemicals are so unsafe that we can do without them.I request all of you to teach your children the dangers of the chemical time bomb that is ticking.

  Continued .........................
  
  Rarely can an MSDS be found that discusses harm from chronic exposures and equally rare is any mention of the synergistic effect of chemicals. Open any of these Material Safety Data Sheet sites to confirm that fact:
  
  Material Safety Data Sheets at Oxford University, UK -- http://physchem.ox.ac.uk:80/MSDS
  Material Safety Data Sheets at Case Western Reserve -- http://research.nwfsc.noaa.gov/msds.html
  Synergism is the simultaneous action of separate agencies which, together, have greater total effect than the sum of their individual effects. The phenomenon is readily seen in the impact of drugs, but never mentioned on Material Safety Data Sheets required for the sale of toxic chemicals in the United States by the Environmental Protection Agency.
  
  A recent breakthrough in the understanding of Gulf War Syndrome may be changing scientific thinking and promoting further research on chemical synergy.
  
  Researchers at the Duke University Medical Center and the Texas Southwestern Medical School reported in April, 1996 that the simultaneous exposure to topical insecticides [DEET and permethrin] and pyrido-stigmine bromide, a drug taken prophylactically to counteract toxic gas warfare agents, causes nervous system damage in chickens. The full written report is scheduled for publication in the May,1996 issue of the Journal of Toxicology and Environmental Health.
  
  Both the team led by Robert Haley at Texas Southwestern and Modhamed Abou-Donia's group of researchers at Duke found that the many symptoms experienced by Gulf War veterans, including headaches, fatigue, aches, decreased attention and rashes, were similar to the symptoms that presented in exposed chickens.
  
  Chickens given any two chemicals became lethargic, unable to fly, lost weight and coordination and demonstrated tremors. For those administered all three chemicals, paralysis and death occurred.
  
  This observed impact on nerve functioning is significant because survivors of the Gulf War who were exposed to these toxic agents also have demonstrated abnormal nerve function.
  
  Further studies of Gulf War veterans who were exposed are being conducted at Texas Southwestern and are focusing on comparisons between physical findings in humans and those found in exposed chickens.
  
  The results of that work is awaited by veterans, who until now, have been unable to show any relationship between their multiple symptoms and their exposures during the Gulf War.
  
  More significantly, if these discoveries prove correct all manufacturers of commercial and household chemicals will be obligated to begin testing and instituting warnings of the synergistic effects of their products with other commonly used chemicals.
  
  It is this new testing that holds promise for a better understanding of the impact of chemicals on health that has long been advocated by environmental activists, occupational health specialists, recipients of breast implants, those exposed to chlorinated hydrocarbons and sufferers of multiple chemical sensitivity.
  
  Addendum July 22, 1996
  
  The research of Steven F. Arnold and others at Tulane University published in June, 1996 shocked the scientific community. It proves that hormone-disrupting chemicals, known to cause mild effects, when used in combination produce significantly dramatic hormonal effects "Synergistic Activation of Estrogen Receptor with Combinations of Environmental Chemicals," 272 Science 1489-1492 (June 7, 1996).
  
  Combinations of two or three pesticides, which are commonly found in the environment at low levels, are up to 1600 times more powerful than any of the pesticides individually in their impact on hormones.
  
  Some chemicals, which individually do not disrupt hormones, tremendously magnifies the ability of other chemicals to disrupt hormones. That was the finding with chlordane.
  
  The study focused on endosulfan, chlordane, toxaphene and dieldrin, all of which impact a gene making estrogen in animals. Estrogen controls the formation and development of female organs and is strongly associated with both breast cancer and causing male sex organs to be deformed.
  
  This is the beginning of a revolution in scientific knowledge that will profoundly effect the way pesticides are screened and tested.
  
  This research should prompt EPA to immediately require appropriate warnings. Regulations have long been based on studies of individual chemicals and their individual effects. Now EPA must take steps to regulate combinations of chemicals in order to assure appropriate levels of public safety.
  
  The policy implications of the synergistic effect of chemicals will cause a top to bottom re-vamping of chemical regulations. For years, EPA has not tested pesticide products as sold in containers in combination with other chemicals.
  
  The example of chlordane is particularly disturbing because it means that EPA, manufacturers and the scientific community must now assess and evaluate of chemicals long believed to have minor hormonal impacts. Accomplishing such testing will take years and all the while significant damage to people will continue unabated.
  
  The prevailing view that chemicals are safe until proven otherwise is no longer valid and all manufacturers must be required to prove the safety of their products when used in conjunction with other chemicals.
  
  In the meantime, we must reduced the wide variety of chemicals used today and eliminate the use of pesticides until proven safe.
  
  Addendum November 27, 2000
  
  A medical research team headed by Dr. Robert Haley of the University of Texas Southwestern Medical Center at Dallas has discovered and reported brain damage in veterans of the Gulf War.
  
  Doctors believe this brain damage to have been caused by exposure to combinations of low level nerve gas, anti-nerve gas tablets and DEET contained in insect pesticides and repellents. Magnetic Resonance Imaging has identified specific abnormalities in the basal ganglia that impact cognitive skills, including memory, sense of direction, inability to understand instructions and decision-making, often resulting in depression.
  
  The findings were presented at the annual meeting of the Radiological Society of North America at it¹s November, 2000 meeting in Chicago.

  Hermant could just have posted the urls instead of wasting space.
  
  Got to demote back to Trivedi again!

  Mr. Trivedi,
  Not to mention GM food. That is another scare...

  Hello Ivete, ,
  Yes, GM foods are another thing of concern.This is because, defence of body against alteration in Genetic code of natural foods is not at all known.What will be the reactions over a period of time are an unknown and grey area.
  Research is going on at fast pace to know and understand GM foods.
  I would be happy if you can dig deep in some archives and bring out some thing of interest.

  The Effects of Neurotoxins on Human Health:
  Mercury, Lead, and, Pesticides
  
  by Waterose
  
  --------------------------------------------------------------------------------
  The word "neurotoxic" literally translates as "nerve poison". Broadly described, a neurotoxicant is any chemical substance which adversely acts on the structure or function of the nervous system. It is important to understand not only the effects and types of neurotoxicants, but also the sources and pathways by which these substances enter the environment. Neurotoxicants are ubiquitous in the environment and they have a serious impact on human health (Isaacson,1992). Neurotoxicants affect the nervous system in different ways; this depends on the molecular structure of the neurotoxic chemical substance and the specific function and structure of the nervous system tissue (Isaacson, 1992). In order to understand the effects and classes of neurotoxicants, it is important to understand the functions and structures of the nervous system.
  The nervous system has three overlapping functions: sensory input, integration, and motor output (Campbell, 1993). The peripheral nervous system (PNS) carries signals from the sensory input organs to the brain and carries output instructions from the brain to the motor controls. The integration of the input/output signals is controlled by the central nervous system (CNS) which includes the brain and the spinal cord. The nervous system has two types of cells; transmitting neuron cells which conduct electrical impulses or signals, and supporting glial cells which provide structural integrity for the nervous system (Campbell, 1993). The neuron cells, from receiving end to transmitting end, are comprised of several components. The branched dendrites receive the incoming signal. The cell body houses the nucleus and other organelles. The axon and the axon hillock conduct signals away from the cell body. The axon is wrapped by the Myelin sheath which is made of a series of Schwann cells which grow around the axon. Schwann cells are high in lipids and are therefore poor electrical conductors, they serve to focus the electrical impulses inside the axon. The axon is terminated by the branched synaptic terminal where the signal is passed onto another neuron via the neuron pathway. The flow of electrical impulses is controlled by the ion gradient across the membrane wall. The interaction between the sending neuron, or the presynaptic cell, and the receiving cell, or the postsynaptic cell, is controlled by both electrical synapses and chemical synapses.
  
  Neurotoxicants are chemical substances that injure the neurotransmission of signals. There are three basic types of damage that can occur (Internet, Neurotoxicity Scorecard). Neuronopathy refers to general damage to the neuron cell body. Axonopathy refers to damage to the neuron axon. Myelinopathy refers to damage to the Myelin sheath. The symptoms of neurotoxic poisoning in the CNS and the PNS differ because each of these nervous systems have different functions. Neurotoxins that act on the CNS impair neurotransmission in the brain and the spinal cord causing confusion, irritability, fatigue, and other behavioural changes. Metals, such as mercury and lead, affect the CNS. Neurotoxins that act on the PNS impair neurotransmission in the other biological systems causing weakness, prickling or tingling in the limbs and loss of motor control. Organic pesticides, such as organophosphates, affect the PNS. Neurotoxicants, whether in the form of metals, organics, or pesticides, are omnifarious and pose a serious threat to human health.........

  Hemant dislikes chemistry! He says:

  Dear Hubbers,
  I’ve seen some useless posts with the same IP address of Idiappam (@ cache139.156ce.maxonline.com.sg) in Tamil Films section as well. But the poster uses different handles every time. If this is idiappam you can understand his standard by reading the posts in the following thread ;
  http://www.forumhub.com/tfilms/15128.05.05.09.html
  
  Idiappam,
  I’ve enjoyed most of your posts in Thamizh Histroy section and I thought you were a knowledgeable and mature person. But after reading all the craps posted by you here in Indian Food section and Tamil Films section(if it is you actually), I think I was wrong in my opinion about you

  Roshan, my boy, don't try to be too smart. Idon't appear in any other handles on Forumhub.
  
  YOu don't understand this issue with Herman. Herman is a kind of man who thinks he can put down anyone who disagrees with him by insults. I have talken a lot a abuses on Tn history section. But I tolerate them = the only reason is that I had more respect for them - Karuvaayan and the likes- for they dared to look at me in the eyes when they attack me. Unlilke this 'Trivedi' big gut who hasn't got the guts to behave the same.
  
  This is a public forum, my boy, Roshan. So just ask you beloved Herman to use more tact.
  
  I don't really care about opinions about me!
