Pentachlorophenol (PCP) is a man-made substance often found as dark gray to brown dust, beads, or flakes, primarily used industrially as a fungicide and wood preservative. Pure Pentachlorophenol forms colorless crystals and is slightly soluble in water, but humans usually encounter the impure form. It is toxic through inhalation, ingestion, and skin absorption, and is classified as a possible carcinogen. Pentachlorophenol′s primary biochemical effect is the active uncoupling of oxidative phosphorylation, inhibiting energy release from ATP breakdown. Exposure can affect the liver, kidneys, and central nervous system, and cause dermatitis and chloracne. It increases cellular oxygen demand, leading to a rise in respiration rate. Laboratory studies suggest it influences genes related to apoptosis, oxidative stress, glutathione metabolism, and mitogenic response.
