See book keywords and concepts |  Talking about adding insult to male injury, researchers also found that mature male frogs exposed to atrazine had a decrease in testosterone to levels equivalent to that found in females. "I was very much surprised at the impact of atrazine on developing frogs," said Tyrone B. Hayes, professor of biology at the University of California at Berkeley. Hayes's study has gotten a cold reception from agricultural interests. Environmental Health News reports: "The Minnesota Pollution Control Agency last fall canceled Hayes' keynote speech on atrazine scheduled for a conference this month. | | The scary part of-what Hayes found is that the doses at which atrazine profoundly feminizes frogs were as low as 0.1 part per billion. "As the amount of atrazine increased, as many as 20 percent of frogs exposed during their early development produced multiple sex organs or had both male and female organs. Many had small, feminized larynxes."
Hayes's research team said that the effect on the frogs could have resulted from atrazine causing the body to produce more of the enzyme aromatase, which is present in vertebrates. |

Finally, let me offer in evidence the following: atrazine is a powerful herbicide that, according to Michael Pollan in the New York Times, is applied to 70 percent of America's cornfields. At concentrations as low as 0.1 part per billion, the herbicide will chemically emasculate a male frog, causing its gonads to produce eggs. According to Pollan, who is a superb journalist and reporter known for his detail and accuracy, traces of atrazine routinely turn up in American waterways at concentrations much higher than 0.1 part per billion. |

Meanwhile, unbeknown to her, her two-year-old is coming down with a coxsackievirus she picked up at daycare, and Mom just shared the end of a Popsicle with her, so the virus is beginning to work on her mast cells as well. |

It isn't only the fish of the Northwest or frogs in the Midwest that face tough times. Polar bears don't have it any easier. The same chemicals that produce endocrine disruptions and genetic mutations in the Midwest's wildlife are part of the fossil fuel mentality that is also having an impact in the Arctic. | | Nebraska drinking water was routinely contaminated with atrazine, acetochlor, and alachlor, three chemical herbicides with a record of causing either ovarian or other cancers, endocrine disruption, and other serious health problems.2'3-4'5
That night as I lay down to sleep, Sioux Indian thunderclouds clapped above me, shook the room, and made me feel like a leaf on the prairie. All night, lightning and thunder filled the sky, and the rain fell furiously like arrows into the earth. I turned on CNN halfway through the night and listened to the news. It was August 23, 2005. | | Hayes's research team said that the effect on the frogs could have resulted from atrazine causing the body to produce more of the enzyme aromatase, which is present in vertebrates. Aro-matase is used by the body to convert the male hormone testosterone to the female hormone estrogen.32
Although these effects are being found at a fraction of a part per billion in tiny vulnerable amphibians, we are consuming water with amounts around three parts per billion. |

See book keywords and concepts | | According to Pollan, who is a superb journalist and reporter known for his detail and accuracy, traces of atrazine routinely turn up in American waterways at concentrations much higher than 0.1 part per billion. But American regulators generally won't ban a pesticide till the bodies or cancer cases start to really pile up—that is, until scientists can prove beyond a reasonable doubt that the suspected molecule "causes" illness in humans or ecological disaster. |

For the dog, there is tick and flea killer: more pesticides. | | Despite such danger signals, in the United States we apply greater quantities of pesticides, such as the weed killer atrazine, to suburban tracts than to agricultural land. Just think back again to Becky, who pulled into her suburban driveway just as the lawn company was pulling away after spraying the crab-grass and dandelions.
Throughout Becky's day, we can trace chemical triggers that tax her immune system and those of her children. As Becky and her children prepare to cross the street in the morning, they are blasted with microparticle bursts of exhaust from a diesel bus, then a truck. |

Animal studies show liver, heart, and kidney damage, tumors in the uterus and breast, and hormone disruption.
Ciba-Geigy has spent more than $25 million, submitted 14,000 pages of defense in response to the epa desire to tighten restrictions on atrazine, and launched a letter-writing campaign (the epa has received more than 87,000 letters) in order to keep atrazine on the market. |

Chlorine has long been added to public water supplies to kill disease-causing bacteria. However, the levels of chlorine in drinking water today can be quite high, and some by-products of chlorine are known carcinogens. As a result, the U.S. |

All DCPA metabolite detections were at a small fraction (0.2% or less) of the HAL. The median atrazine levels were also low. Five pesticides (alachlor, atrazine, dibromochloropropane, ethylene dibromide, and y hexachlorohexane [lindane]) were detected in a small number of samples at levels above their MCLs.

By 1988, 96 percent of the annual corn crop (grown on 65 million acres of land in the United States) was sprayed. atrazine is the best-selling pesticide in the nation (68-73 million pounds in 1995) and accounts for one-quarter of Ciba-Geigy's crop chemical business.

In Hens
• Hens fed malathion and carbaryl are reported to develop a number of health problems which increase as the dose of pesticide in their mash is increased. Studies indicated they had defective eggs, decreased hatchability and more birth defects. The liver and kidney of the affected chicks stored more malathion than usual. |
