We use a formula to convert workplace limits to home limits. Most people can't smell chloroform until levels reach 133 ppm or higher. If you can smell the chemical, the level is too high to be safe. The Wisconsin Department of Natural Resources regulates the amount of chloroform that can be released by industries. Immediately or shortly after exposure to a level of 100 ppm of chloroform in air, a person may feel tired, dizzy, and have a headache.
Chloroform is suspected of causing cancer.
Liver and kidney tumors have been reported in laboratory animals. Any exposure to a cancer-causing chemical may increase your risk of developing cancer. The reproductive and developmental effects of chloroform are not known. However, chloroform can enter the bloodstream of a developing baby. Damaged liver or kidney function can result when levels of chloroform reach 300 ppb in water or 0.25 ppm in air.
