The previous studies have shown Attention Deficit Hyperactive Disorder occurs with greater frequency in children exposed to pesticides. This study, using mice and post-mortem brain analysis, attempted to provide a biological explanation as to why ADHD would result from pesticide exposure.
After exposing pregnant mice to pyrethroid pesticides, the offspring were observed and brain structures analyzed.
According to the researchers, mice exposed to pyrethroid pesticides during development exhibit hyperactivity, impusive-like behavior, deficits in working memory and deficits in attention. Brain analysis showed the exposed mice also had elevated levels of what is called dopamine transporter and dopamine receptor levels.
Dopamine is a neurotransmitter used in communication between brain cells. The picture at left is not from this study but does show a normal brain of a 20 year old young man with Learning Disabilities who died in a construction accident and reported by Dr. Albert Galaburda at Harvard Medical School.
More on this and abnormal brain structures in special-ed students can be see here. Environmental Toxicology, Volume 19 6: This will tell him the number of immune system fighting white blood cells you have.
People with the lowest 2. As far as the numbers go, it is better to be in the upper half of this range thereby giving you more immune cells to fight bacteria, viruses and cancer. People at the very low end of "normal" are typically predisposed to higher rates of infection. These cells perform a critical role in destroying early stages of viral infections and cancer.
In a study done at the Department of Chemistry, Tennessee State University, researchers found that very low levels of carbamate pesticides used in agriculture could weaken the ability of natural killer cells to destroy viruses or cancer cells. The toxicity of each of the compounds studied increased very significantly with length of exposure.
Krigbaum, Gregory Yeh, et. Unfortunately, DDT can still be manufactured in the U. Therefore, exposure comes not only from chemically grown foods but also from living close to agriculture in Florida and California.
Breast Cancer Research and Treatment, Volume Breast cancer rates in the U. This study conducted at the US Army Institute of Surgical Research and Texas Tech University Health Science Center in Lubbock Texas found that cancerous human breast tissue contained the chemical heptachlor epoxide found in the common home pesticide chlordane at levels 4 times higher than non-cancerous breast tissue.
Chlordane was the primary termite prevention pesticide used in over 30 million U. An estimated 50 million U. For more information on chlordane go to www. Cassidy, Sridhar, George M.
Vaughan Tox Free, Inc. Environmental Health Perspectives Volume 9: The pesticide category believed to be the culprit is known as chlorophenoxy herbicides that contain the chemical 2,4-D.
Chlorophenoxy herbicides are used to kill a variety of weeds and are also commonly used by city and county maintenance departments for grass and weed control along roads, canals etc.
Infant deaths for male babies from congenital anomalies related to the birth defects was over 2. In conclusion, the scientists stated - "These results are especially of concern because of widespread use of chlorophenoxy herbicides.
Researchers said frogs appear to be made more vulnerable to a common parasite when exposed to the pesticides atrazine and malathion.
The parasite, a burrowing trematode worm, tends to infect the hindquarters of developing tadpoles.— iii — preface This publication, Organic Agriculture: African Experiences in Resilience and Sustainability, demonstrates that organic management can benefit people, the economy and ecosystems and that this can be achieved in Africa, where hunger and degradation stubbornly persist, despite decades of development efforts.
Founded in , Biodynamic farming is the oldest 'green' farming movement, and forerunner of organics. All biodynamic farmers and growers practice organic methods of cultivation, are against genetic modification (GM), and share its ideals, but there are important differences.

The Natural Resources Defense Council works to safeguard the earth - its people, its plants and animals, and the natural systems on which all life depends. Americans are consuming more dangerous chemicals than ever before. Agriculture is the cultivation of land and breeding of animals and plants to provide food, fiber, medicinal plants and other products to sustain and enhance life. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The study of agriculture is known as agricultural.
INTRODUCTION: While new studies on the negative effects of pesticides on human health are completed each year by major government and university research centers, the majority of these studies remain "silent" in medical journals and do not reach the public via major news schwenkreis.com reduction in public awareness appears to have worsened over the past several decades.
07 Mark Lynas from Oxford Farming Conference on Vimeo.. I want to start with some apologies. For the record, here and upfront, I apologise for having spent several years ripping up GM crops. The USDA has recently embraced hydroponics as organic and has dropped the proposed rule on animal welfare.
This has created a disconnect between organic farming’s role in fostering healthy soils and practices now allowed under the organic seal.
