Which of the following describes sources of ethylene glycol exposure?

• A. Antifreeze and automotive coolant only.
• B. Industrial solvents and rust removers.
• C. Antifreeze and coolant for automobiles; industrial solvents; rust removers; color film processing fluids; heat exchange fluids.
• D. Household cleaners only.

Answer: (C)

Ethylene glycol exposure comes from a wide range of products, not just car antifreeze. In addition to automotive antifreeze and coolants, it can be found in industrial solvents, rust removers, color film processing fluids, and heat exchange fluids. This broad presence means the best description of exposure sources includes all these categories, capturing real-world scenarios from automotive leaks to occupational exposures in manufacturing and photography, as well as cooling-system fluids. The other options are too narrow, omitting several legitimate sources such as film processing fluids or heat exchange fluids, or focusing only on household cleaners.
