My previous post was narrowly focussed on the effects of DDT and DDE on male reproductive health. I will now expand.

Testing at the GHNS showed the presence of pesticides including DDD, DDE, DDT, Aldrin, and Chlordane.There is a  quote on the effects of some of the pesticides at the bottom of this post.

Study links DDT, obesity in women

Muskegon Chronicle (via
Organic Consumers Association ) - MI, March 20, 2009 Straight to the Source

WEST MICHIGAN — The daughters of women who eat Lake Michigan fish laced with the toxic remnants of DDT are at greater risk of becoming obese, according to a new study.

Researchers at Michigan State University have discovered that prenatal exposure to a derivative of DDT — an insecticide commonly used until it was banned in the 1970s — may play a role in the obesity epidemic in women.

Mothers’ Pesticide Exposure Linked to Deficits in Children

Updated: Mar 17th 2010

WEDNESDAY, March 17 (HealthDay News) — Prenatal exposure to pesticides may lead to persistent adverse effects on brain development in children, according to research published online Feb. 25 in Environmental Health Perspectives.

… Children with prenatal exposure from their mothers’ greenhouse work had deficits related to motor speed and coordination, visuospatial performance, and visual memory.

Tiny pesticide exposure during pregnancy can have long-term impact on female offspring

Study confirms chlorpyrifos levels far below “toxic” threshold can impair learning, change brain function and alter thyroid levels into adulthood for tested mice.

By Greg Bowman
A new animal study accentuates the risk of ultra-low levels of the common pesticide chlorpyrifos to cause long-lasting birth defects in female offspring of exposed mothers. The daughters exhibited learning delays, disturbed brain function and altered thyroid levels. Significantly, these symptoms resulted from low toxicity exposure during late gestation—an impact route not even part of current regulatory pesticide testing.

The Few, The Proud, The Forgotten



The Department of Health and Human Services (DHHS) determined that DDT may reasonable be anticipated to be a human carcinogen. The International Agency for Research on Cancer (IARC) determined that DDT may possibly cause cancer in humans. The EPA determined that DDT, DDE, and DDD are probable human carcinogens.

Chlordane affects the nervous system, the digestive system, and the liver in people and animals. Headaches, irritability, confusion, weakness, vision problems, vomiting, stomach cramps, diarrhea, and jaundice have occurred in people who breathed air containing high concentrations of chlordane or accidentally swallowed small amounts of chlordane. Large amounts of chlordane taken by mouth can cause convulsions and death in people.


People who intentionally or accidentally ingested large amounts of aldrin or dieldrin suffered convulsions and some died. Health effects may also occur after a longer period of exposure to smaller amounts because these chemicals build up in the body.


Exposure to endrin can cause various harmful effects including death and severe central nervous system (brain and spinal cord) injury. Swallowing large amounts of endrin may cause convulsions and kill you in a few minutes or hours.


There is no reliable information on health effects in humans. Liver damage, excitability, and decreases in fertility have been observed in animals ingesting heptachlor. The effects are worse when the exposure levels were high or when exposure lasted many weeks.


Endosulfan affects the central nervous system and prevents it from working properly. Hyperactivity, nausea, dizziness, headache, or convulsions have been observed in adults exposed to high doses. Severe poisoning may result in death.


There is very little information on how methoxychlor can affect people’s health. Animals exposed to very high amounts of methoxychlor suffered tremors and convulsions and seizures.
