Pentachlorophenol

PENTACHLOROPHENOL

Pentachlorophenol is a manufactured chemical that does not occur naturally. It has a molecular weight of 266.34 g/mol. In its molecular form, it looks like C6HCl5O. It has a melting point of 174 degrees C. It has a boiling point of 310 degrees C. Its density is 1.978 g/mol. Pure pentachlorophenol exists as colorless crystals. Impure pentachlorophenol (the form usually found at hazardous waste sites) is dark gray to brown . The impure form exists as dust, beads, or flakes. Humans are usually exposed to impure pentachlorophenol, also known as technical grade pentachlorophenol.

Pentachlorophenol was widely used as a pesticide and wood preservative. In 1984, the purchase and use of pentachlorophenol became restricted and only certified applicators had access to the chemical. Hence, pentachlorophenol is no longer available to the general public. However, pentachlorophenol is still used industrially as a wood preservative for utility poles, railroad ties, and wharf pilings.

In general, populations are exposed to low levels of pentachlorophenol in things such as: contaminated indoor and outdoor air, drinking water, food and soil. Populations who live near a wood treatment facility or near a factory where utility poles or railroad ties are produced may be exposed to pentachlorophenol in the air or by coming in contact with the wood. In addition, people who live near hazardous waste sites may be at risk for being exposed to higher than usual levels of pentachlorophenol.

When people are exposed to higher than normal levels of pentachlorphenol, it can cause the cells in the body to produce excess heat. Therefore, these people may run a very high fever, sweat immensely and have a hard time breathing. Your body temperature could potentially increase to dangerous levels causing damage to various organs and tissue. Death is possible in extreme cases. Damage to your liver as well as your immune
