At a glance
CDC conducts epidemiologic studies to better understand the relationship between human health and emerging environmental hazards. Areas of research include harmful algal and cyanobacterial blooms (HABs) and per- and polyfluoroalkyl substances (PFAS).
Background
Environmental epidemiologists at CDC develop innovative approaches to collect and analyze exposure and health data. The data helps them better understand the relationship between human health and emerging environmental exposures. Information gathered from their studies translates environmental public health science into actionable guidance, resources, and tools for environmental public health practitioners.
Key research areas include:
Additionally, emerging hazards identified through the surveillance of poison center data are prioritized for future research activities.
Examples of current research activities are listed below. For information on the results of past research activities, visit the environmental health studies publications webpage.
Harmful algal and cyanobacterial blooms
Cyanotoxins in Air Study (CAST)
CDC is conducting a study in South Florida to assess the health effects of exposure to cyanotoxins in the air. CAST evaluates exposures to cyanotoxins among people who live or work near:
- Lake Okeechobee
- St. Lucie River
- Caloosahatchee River
- Cape Coral Canals
CDC is conducting this study to determine if breathing in cyanotoxins can make people sick or cause symptoms. Cyanotoxins are toxins (poisons) sometimes produced when small, plant-like organisms called cyanobacteria (blue-green algae) rapidly grow out of control or bloom.
Using electronic health records to assess exposures to cyanobacterial blooms
CDC is studying the relationship between symptoms identified through electronic health records and cyanobacterial blooms. This is being done in collaboration with:
Per- and polyfluoroalkyl substances
CDC is conducting research projects with the Agency for Toxic Substances and Disease Registry and other partners to study the health effects of PFAS.
Specifically, CDC is researching the associations between PFAS and:
- Cardiovascular disease
- Birth and mortality outcomes
- Cancer
