Consequences of DDT Exposure Could Last Generations
scientific american ^

Hailed as a miracle in the 1950s, the potent bug killer DDT (dichloro-diphenyl-trichloroethane) promised freedom from malaria, typhus and other insect-borne diseases. Manufacturers promoted it as a “benefactor of all humanity” in advertisements that declared, “DDT Is Good for Me!” Americans sprayed more than 1.35 billion tons of the insecticide—nearly 7.5 pounds per person—on crops, lawns and pets and in their homes before biologist Rachel Carson and others sounded the alarm about its impacts on humans and wildlife. The fledgling U.S. Environmental Protection Agency banned DDT in 1972.

Friends and family often ask Barbara Cohn, an epidemiologist at Oakland's Public Health Institute, why she studies the effects of the long-banned pesticide. Her answer: DDT continues to haunt human bodies. In earlier studies, she found that the daughters of mothers exposed to the highest DDT levels while pregnant had elevated rates of breast cancer, hypertension and obesity.

Cohn's newest study, on the exposed women's grandchildren, documents the first evidence that DDT's health effects can persist for at least three generations. The study linked grandmothers' higher DDT exposure rates to granddaughters' higher body mass index (BMI) and earlier first menstruation, both of which can signal future health issues.

“This study changes everything,” says Emory University reproductive epidemiologist Michele Marcus, who was not involved in the new research. “We don't know if [other human-made, long-lasting] chemicals like PFAS will have multigenerational impacts—but this study makes it imperative that we look.” Only these long-term studies, Marcus says, can illuminate the full consequences of DDT and other biologically disruptive chemicals to help guide regulations.

The science is settled. It doesn’t hang around nor is it harmful to humans.

I agree that is the dumbest grab at a conclusion I have ever seen. Could it possibly be all the hormones in the food that is making their fat granddaughter’s menstruate earlier?

When the president of the company that made DDT testified before Congress he had a bowl of DDT on the table. Once in a while he swallowed a teaspoon of it in a vain attempt to show it was harmless.

So they have ruled out all other factors that could explain the obesity and breast cancer risk?

Like diet, not nursing, smoking, drinking, etc?

I bought a 2.5-gallon jug of 46% glyphosate for $55 bucks from Tractor Supply recently. That’s enough to last me for many years. Beats the pants off Round-Up for $20 a quart.

The same stuff just doesn’t have some of the fast-acting salts added to the Round-Up formulation. Kills em dead, just a little slower.

Oh, and I have a mosquito fogger too! How on earth am I still here?

BS.

I mean, pure unadulterated BS.

If you do not have an exoskeleton DDT is harmless to you.

The old post hoc ergo propter hoc fallacy.

Correlation and causation are not the same thing.

Too funny. I did exactly that. The siren on top of the slow moving truck looked so cool with the fog distortion.

The roads at our summer cottage used to be sprayed with used oil every month to hold down the dust. I miss that smell too.

They just found the guy next door dead. Agent Orange sufferer. We can make some nasty stuff.

Every campground we parked our travel trailer at on summer vacations, had Jeeps with foggers that ran the whole campground every day at dusk.

We all rode our bikes behind them.
