Research Includes Health Impacts and Conditions Linked to Toxic Exposure

Attorney General Charity Clark joined a coalition of 14 attorneys general today in sending a letter to Congress, urging members to oppose two Congressional bills that would prohibit the U.S. Environmental Protection Agency (EPA) from relying on scientific assessments from the Integrated Risk Information System (IRIS) program, which are critical to protect against deadly exposure to toxic chemicals.

The letter also urges Congress to oppose the Trump Administration’s effort to dismantle the EPA Office of Research and Development (ORD), which is the research arm of the EPA that provides the scientific basis for EPA’s work.

In the letter, Attorney General Clark and the coalition explain IRIS assessments are the result of an unbiased, scientific review that determines at what level the many chemicals that enter the environment through industry and other sources are harmful to human health. Without knowing the level at which these chemicals can cause a risk to human health, such as cancer and birth defects, it would be difficult for EPA to adequately protect the public from exposure, which will jeopardize the health and safety of the entire county.

The letter goes on to state ORD conducts critical scientific research that is used in a wide range of areas, including protecting drinking water sources from natural disasters and terrorist attacks, studying air pollution caused by wildfire smoke and researching PFAS and other emerging contaminants. The reported plan to dissolve ORD and fire more than 1,000 scientists would have immediate consequences and make it difficult for EPA to meet its statutory requirements of using the best available science to inform its work.

ORD provides integral scientific and technical resources to states that helps states protect residents from environmental pollutants that can cause significant health risks. The letter also highlights that IRIS assessments are used by EPA to determine which communities across the country face higher risks from exposure to hundreds of toxic chemicals, such as ethylene oxide.  

Joining Attorney General Clark in sending the letter are attorneys general of Arizona, California, Colorado, the District of Columbia, Illinois, Maryland, Massachusetts, Minnesota, New Jersey, New York, North Carolina, Washington and Wisconsin.
