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.

HUH? Is the DDT scare back on again? Barrels of the stuff dumped off Santa Barbara? No mosquitos found near the dump site?
So could and does malaria.
Now that they’ve “discovered” this, how about giving us how many millions of people died from Malaria, etc in the world because DDT was stopped? MILLIONS!!! But that somehow doesn’t count. Thanks to “Silent Spring”, the liberals found a way to kill more people.
Linked? Lol, iow totally made up bs.
Could last for multiple generations = we can’t find enough problems in one generation
SA has long ago lost trust. I tend to agree that DDT is not a good thing, but being a math/STEM type, I’d go over that “study” with a fine tooth comb before proceeding any further. Just sayin’.
Just as the eugenicists like Rachel Carlson wanted.
every kid what rode his bike behind the foggers should be dead by now then...
Siblings and I were sprayed by crop dusters in the 50's and 60's.

I for one............................
Maggots would soon arrive and we used the DDT. There was no other "garbage" option back then.
We did in Florida in the early 50’s. Still kickin’. Then again, that may explain a lot........... Just sayin’. :-}
Or at least having early menstruation......

What about grandsons? Collateral damage?
