"This report was developed by the Agency for Toxic Substances and Disease Registry (ATSDR) in response to a request by the International Joint Commission (IJC) regarding the public health implications of hazardous substances found at the U.S. Areas of Concern (AOCs). This report should not be construed as a traditional analytic epidemiologic evaluation. Instead, it should be viewed as an assessment to identify the co-occurrence of elevated patterns of morbidity and mortality and environmental contamination that may merit further hypothesis-based epidemiologic study. Despite limitations, this report provides a comprehensive evaluation of patterns of environmental contamination and the demographics of vulnerable populations in the 26 AOCs."
