New York scientists to study environmental toxins impact

ALBANY, N.Y. (AP) - New York scientists have been awarded a $5 million federal grant to study long-term human exposure to chemicals in the environment.

Chemicals can pop up anywhere: From plastic bottles to toys, medical equipment, pillows and upholstery. Scientists are studying whether humans exposed to small amounts of environmental compounds retain the chemical or if they have lasting effects.

To test exposure, scientists take samples of urine, blood and saliva. They're measuring how much and what kinds of chemicals are in blood and fat tissue. Some chemicals are metabolized and leave the body, others stay around.

Scientists want to track exposure so they can learn if these compounds increase in humans over time.
