Pentachlorophenol (PCP) is an ... to large amounts of PCP can cause harmful effects on the liver, kidneys ... PCP have half-lives in blood of 30 to 50 hours in humans.
Well established developmental effects are cleft palate, hydronephrosis, disturbances in tooth development and sexual development, and endocrine effects. [24] Surprisingly, enzyme induction, several developmental effects and aversion to novel foods occur at similar dose levels in animals that respond differently to acute high-dose toxicity.
In 1994, the US EPA reported that dioxins are a probable carcinogen, but noted that non-cancer effects (reproduction and sexual development, immune system) may pose a greater threat to human health. TCDD, the most toxic of the dibenzodioxins, is classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC).
The halflife of heptachlorodibenzo-p-dioxin is calculated to be 3.6 years. This estimation was based on the analysis of fat tissue biopsies collected with an interval of 28 months from on 14-year-old girl who for a period of about 2–3 years had been exposed to technical pentachlorophenol.
Chemical structure of 2-chlorophenol. A chlorophenol is any organochloride of phenol that contains one or more covalently bonded chlorine atoms. There are five basic types of chlorophenols (mono- to pentachlorophenol) and 19 different chlorophenols in total when positional isomerism is taken into account.
Many organochlorine compounds have been isolated from natural sources ranging from bacteria to humans. [3] [4] Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.
People are ingesting borax. Also known by its chemical name sodium borate decahydrate, borax is a salt typically used to kill ants and boost laundry detergent, among other household cleaning needs ...
In 1963, an on-site fire released 20,000 gallons of pentachlorophenol (PCP) from tanks onto the soil. Another fire was documented in 1987 releasing high levels of dioxins. With many orders and remedial actions to clean up the site, KCI Superfund Site is under monitored recovery to clean the affected groundwater and soil contamination .
