EPA scientists are exploring ways to use some very small materials to clean up some very big environmental problems. Research chemist Dr. Souhail Al-Abed and his colleagues have synthesized activated carbon with nanoparticles of iron/palladium bimetallic to produce a new nano-scale treatment to clean up pollutants. The new, tiny technology is offering promise where conventional technologies have been limited in detecting, treating, removing, and preventing environmental contaminants.
The research is proving particularly useful in dealing with PCBs, a family of persistent organic chemicals that have been linked to a host of dangerous health effects, including cancer. Dr. Al-Abed and his research group found that infusing the carbon with nanoparticles not only made it more effective at adsorbing contaminants, but also degraded the PCBs to less harmful compounds.

This summer, EPA scientists began sampling air across Cleveland, Ohio, to better understand the links between sources of air pollution and adverse health effects. The research will be used to develop new tools and models for air quality managers to reduce and control air pollutants at their source.
Air pollution sources are varied, ranging from motor vehicles to industry, power plants, agriculture and home equipment such as lawn mowers. They can also be formed photochemically in the air from different sources. As scientists analyze the air samples obtained in the study, they look for chemical components that can lead them to their source or sources. They will also measure the amount or concentration of pollutants, which is important in determining potential health impacts.
A scientist's notebook is a career staple. Home to ideas, questions, drawings and data, it's a treasure trove of information about the scientific process. EPA's Science Notebook offers a similar view into science at EPA, featuring stories, scientist interviews, videos, podcasts and more.
The TTN is a collection of technical Web sites containing information about many areas of air pollution science, technology, regulation, measurement, and prevention.
EPA uses environmental databases and scientific tools to learn more about chemical risks and conditions of the environment, whether locally or for the whole nation.

EPA uses a wide variety of scientific and technical models to support our decisions and policies. Models increase the level of understanding about natural systems and the way in which they react to varying conditions.
EPA's multi-year plans enable the Agency to focus on the highest priority needs for science and to coordinate research across its laboratories and centers to achieve research goals.
EPA's National Research Programs coordinate research planning across the Agency in areas like drinking water research and global change research.
The Office of Research and Development (ORD) is the scientific research arm of EPA. ORD's leading-edge research helps provide the solid underpinning of science and technology for the Agency.
Research strategies frame the scientific questions associated with important environmental issues and delineate the research needs and relative priorities required to address those questions.
