What are trichlorophenols?
Trichlorophenols are part of a group of human-made chemicals called chlorophenols that are produced by adding chlorines to phenol. Trichlorophenols do not occur naturally. Most trichlorophenols are no longer produced in the United States but are still available in other countries. In the past, they were used mostly as disinfectants and pesticides such as fungicides and herbicides. They also were used to preserve wood, glue, and leather. The human body can change other chemicals to trichlorophenols. When you are exposed to hexachlorobenzene, pentachlorophenol, and hexachlorocyclohexane, your body forms trichlorophenols. Two different trichlorophenols were measured in your urine sample: 2,4,5-trichlorophenol and 2,4,6-trichlorophenol. Hexachlorocyclohexane has several forms: alpha, beta, gamma, and delta. The gamma form is usually called lindane. It is a persistent pesticide once used in agriculture and still used to treat scabies and lice on people. The other forms were once used as fun
