Hey, everybody. I'm really happy to have one of my old old friends, David Carpenter.

So David Carpenter is a public health physician who received his MD degree from Harvard Medical School.

He has focused primarily on neurobiology and electric physiological techniques.

And he has become one of the leading global experts on the impact of

endocrine disruptors on sexual development of neuro-toxicological chemicals on IQ and behavior

in children and adults. He had a research physician at the National Institute of Mental Health

in the Armed Forces Radiology Research Institute, but as Marilyn, before he was recruited as the

director of the Lazarus Center of Laboratories and Research at New York State Department of

Health, and I'm not going to read your other credentials because there are too many pages and

that is boring for it that this guy is really smart and he knows what he's talking about and he's

feared by defense attorneys. I want to just get your take on a couple of issues. We'll just play

again because I've written three papers the last two months that are amazing. We really need to think

and explore before we bring these chemicals on the market. As you said, I've been very involved

in health effects of PCBs. They were manufactured from the late 1920s. Nobody thought they

did anything harmful till they were banned by the toxic substance control act in the late 70s.

Now, what we find is our knowledge of how dangerous they are is growing much more rapidly

than these chemicals which are persistent are being reduced in our environment and also in our

in our bodies. It was just on another case yesterday of the harm that children in a school

near Seattle, Washington have suffered because of the PCBs in the air in their school. And if you

have a chemical in the air, you breathe it every moment of the day that you're in that building.

And these children have serious neurobehavioral effects and are going to be at risk for other

more chronic diseases as they grow older. And people should know this. At the time when
