Agency for Toxic Substances and Disease Registry

The Agency for Toxic Substances and Disease Registry (ATSDR) is a group of people who study the chemicals and other things in the environment that could make people sick. They look for things like pollution in the air we breathe or chemicals in the water we drink. They also study how these things can hurt our bodies and make us sick.

The ATSDR works with other organizations to make sure we are safe from these harmful things. They make rules and laws about how much of these things can be in our environment and work to clean up areas where these things are found. They also work with doctors to help people who may have been exposed to these things and to keep them from getting even sicker.

Overall, the ATSDR is like a team of superheroes who work to keep us safe from harmful things in our environment.
