A child in a household using home and garden pesticides has a 6.5 times greater risk of developing leukemia.
Dog owners who use the herbicide 2, 4-D* four or more times per season increase their dog’s chances of suffering lymphoma by two times.
* 2,4-Dichlorophenoxyacetic acid (2,4-D) is a common systemic herbicide used in the control of broadleaf weeds. It is the most widely used herbicide in the world, and the third most commonly used in North America.  2,4-D is also an important synthetic auxin, often used in laboratories for plant research and as a supplement in plant cell culture media such as MS medium.
2,4-D is sold in various formulations under a wide variety of brand names. 2,4-D can be found in lawn herbicide mixtures such as “Weed B Gon MAX”, “PAR III”, “Trillion”, “Tri-Kil”, “Killex” and “Weedaway Premium 3-Way XP Turf Herbicide”. All of these mixtures typically contain three active ingredients: 2,4-D, mecoprop and dicamba. Over 1,500 herbicide products contain 2,4-D as an active ingredient.
2,4-D is most commonly used for:
Myth: Pesticide exposure is only a problem where the pesticides are applied.
Facts: An EPA study found 23 pesticides in indoor dust and air- many of which had not been used on the premises. 17
Another found 26 different chemicals in dust and 19 in air samples of Cape Cod residences. 18
Herbicides are easily tracked indoors, contaminating the air and surfaces inside residences and exposing children at levels ten times higher than pre-application levels.
Children are the sector of the public most likely to be exposed to lawn pesticides.
Children take in more pesticides relative to body weight than adults and have developing organ systems that are more vulnerable and less able to detoxify toxic chemicals.
Between 1973 and 1991, the overall incidence of childhood cancer increased 10%. Soft tissue sarcoma and brain cancer incidence increased more than 25%.
A study sponsored by the National Cancer Institute indicates that household and garden pesticide use can increase risk of childhood leukemia as much as seven-fold.
Of the 36 most common lawn pesticides:
50 chemicals are on EPA’s list of unregulated drinking water contaminants, including herbicide ingredients such as Diazinon, Diuron, Naphthalene, and various Triazines, including the most common: Atrazine.
Myth: Inerts are just fillers, like water, of no health significance.
Facts: “Inerts” is a soothing term for ingredients that go generally unregulated and untested by EPA due to their “Trade Secret” status, however, many are cited as hazardous to human health by state, federal and international agencies. Despite their name, these ingredients are neither chemically, biologically nor toxicologically inert. Oftentimes these secret ingredients are more toxic than the active ingredient.
Notable Secret Ingredients Include:
Xylene and Toluene (nerve Poisons linked to birth defects, bone marrow and kidney damage.)
Monochlorobenzene (nerve poison and carcinogen, links to birth defects.)
Ethylene Chloride (nerve poison, linked with damage to heart, eyes, liver and adrenal glands.)
<!–[endif]–>Secret ingredients make up 95% of almost three-fourths (72%) of over-the-counter pesticide products.
Of the over 2300 substances EPA believes are used as _inerts_, most (over 1700) are classified as _of unknown toxicity,_
50 as highly toxic with known carcinogenicity, neurotoxicity, adverse reproductive effects, birth defects or other chronic effects, and 60 as potentially toxic.
More than 200 chemicals used as inert ingredients are considered hazardous pollutants and/or hazardous waste under federal environmental statutes.
NOTE: In a 1995 list of inert ingredients, 394 chemicals were listed as active ingredients in other pesticide products.
