  • Federal grant $$ cover staff salary and training.
  • The mission of the partnership is to protect the

public health of the people of Ohio through:

  • Evaluating chemical levels in environmental media

across the state in order to identify potential exposure to toxic chemicals through contact with contaminated water, air, soil and the food chain (fish).

What is the Agency for Toxic Substances and Disease Registry (ATSDR)?

  • The ATSDR is a sister agency of the CDC
  • ATSDR is the principal federal public health

agency involved with hazardous waste and human health issues.

  • ATSDR’s headquarters are in Atlanta, GA , with

10 regional offices throughout the nation.

  • Ohio is in Region V, Chicago.

HAS works closely with ATSDR, the U.S. EPA, Ohio EPA, local health districts and concerned communities at hazardous waste sites throughout Ohio.

  • ODH was contacted by ODOT in July of 2012.
  • We were asked to look at the

available data in order to determine if there was a public health hazard posed to the residents that lived around ODOT’s Former Garage Site.

  • In order for ODH to determine if

there is public health threat, we needed to determine if people were coming into contact with site related chemicals.

  • As people were not drinking TCE-

contaminated water, our main concern focused on the vapor intrusion threat.

Site Chemical of Concern: TCE

What is TCE?

TCE is a man-made chemical that is not naturally found in the environment. It is mainly used as a cleaner in industry to remove grease from metal

  • parts. TCE can also be found in

common household items such as glues, paint removers, typewriter correction fluids and spot removers.

TCE (continued)

How does TCE affect your health?

  • Breathing (Inhalation): Breathing high levels of TCE may cause headaches, lung

irritation, dizziness, poor coordination (clumsy) and difficulty concentrating. Breathing very high levels of TCE for long periods may cause nerve, kidney and liver damage.

  • Drinking (Ingestion): Drinking high concentrations of TCE in the water for long

periods may cause liver and kidney damage, harm the immune system and damage fetal heart development in pregnant women.

  • Skin (Dermal) Contact: Short periods of skin contact with high levels of TCE may

cause skin irritation and rash.

Does TCE cause cancer?

In September of 2011 the U.S. EPA revised their Integrated Risk Information System (IRIS) numbers for cancer and non-cancer effects for Trichloroethylene (TCE). The U.S. EPA newly revised IRIS document has classified TCE as “carcinogenic to humans.” Cancer Studies in Humans found that occupational exposure to TCE was associated with excess incidences of liver cancer, kidney cancer, non-Hodgkin’s lymphoma, prostate cancer, and multiple myeloma, with the strongest evidence for the first three types of cancer.
