Health Effects

On this page:

There is increasing evidence that many chronic diseases and disabilities can be attributed to pollutants in the environment. In this clearinghouse, we look at seven main categories of diseases and disabilities that have been linked with environmental exposures:

For each type of disease or disability, we prepared a separate webpage that compiles the information that is available for Washington State under each of the following headings:

Proportion of Health Effects Attributable to Environmental Contaminants

This section contains a statement summarizing the scientific consensus on the proportion of each type of disease or disability that can reasonably be attributed to exposure to environmental contaminants.

To access some of the most recent peer reviewed papers on the health effects of environmental contaminants, visit the Collaborative on Health and the Environment's (CHE) website at


Summary of Information on Washington State

In this section, we summarize and provide references to scientific information on each disease and disability. The information is categorized into information available from national organizations (e.g. Centers for Disease Control and Prevention), state organizations (e.g. Washington State Department of Health), local organizations (e.g. Public Health-Seattle and King County), and academic institutions (e.g. the University of Washington). We have included data for the entire state, as well as on county or localized levels whenever possible. We also looked for information on race/ethnicity, gender, age, and income levels.


Information on Washington State in Context

This section contains a brief description of how information on each disease or disability in Washington State compares with information from other states or nationally. In some cases, these comparisons were difficult to make because of a lack of information.


Quality of Information on Washington State

In this section, we have assessed the information on Washington State for each disease and disability. We have done this by considering

  • How much information was available;
  • Whether time trend information is available; and
  • Whether information for different locations in the state was available (spatial trends).

In some cases, we have identified areas where there is room for improvement.

We have also noted whether or not each disease or disability is listed on Washington State's "Notifiable Conditions" list. In Washington State, there are legal requirements that require health care providers, health care facilities, laboratories, veterinarians, food service establishments, child day care facilities, and schools to notify public health authorities of suspected or confirmed cases of selected diseases or conditions; these are referred to as "notifiable conditions."

Within each of the health effects pages, we linked all pieces of information back to their original sources, either via a web link to an external site or to a cited hardcopy document.


General Sources of Information

In this section we provide general sources of information for each disease and disability.

As you read through the clearinghouse's health effects page, please direct any questions or additional information sources to We hope to update the health effects pages with the latest Washington State information approximately once a year.
