What is trichloropropane used for?
1,2,3, TCP is an exclusively man-made chlorinated hydrocarbon commonly used as an industrial solvent, cleaner, and degreaser, as well in the production of paint thinners and varnish removers.
Is 123 TCP a VOC?
The USEPA considers 1,2,3-TCP to be a carcinogenic VOC and is therefore included in the included in the unregulated included in the unregulated carcinogenic volatile organic compound rule (UCMR3). The current reporting level at the national level is set at 30 ng/l.
Does TCP cause cancer?
TCP is recognized in California as a human carcinogen, and extensive animal studies have shown that it causes cancer. Short term exposure to TCP can cause throat and eye irritation and can affect muscle coordination and concentration. Long term exposure can affect body weight and kidney function.
What is TCP in toxicology?
Tricresyl phosphate (TCP), is a mixture of three isomeric organophosphate compounds most notably used as a fire retardant and in manufacturing for lacquers and varnishes as a plasticizer. TCP, especially the all-ortho isomer, is the causative agent in a number of acute poisonings.
Does boiling water remove TCP?
Boiling the water does not remove 1,2,3-TCP. Home filtration systems using activated carbon can remove the pollution from water, though filters must be changed more often than usual.
Can water filters remove TCP?
If your home’s water is contaminated with TCP, and large-scale treatment isn’t happening in an acceptable time frame, some residential water filters do remove TCP.
Is TCP safe to drink?
Harmful effects Published advice states that TCP should not be swallowed, and recommends drinking plenty of water if 30ml or more of TCP is swallowed, and seeking medical advice if discomfort persists.
Is TCP toxic to humans?
How dangerous is TCP? The Environmental Protection Agency has concluded it’s “likely to be carcinogenic to humans,” and the California water board warns residents not to shower with tainted water because they might inhale the chemical.
Is TCP toxic?
TCP is a contaminant of interest to the government, private sector and other parties. It is a persistent pollutant in groundwater and has been classified as “likely to be carcinogenic to humans” by the EPA.
How does TCP antiseptic work?
How does TCP antiseptic work? TCP contains halogenated phenols, which helps fight infection and provide relief for various ailments. It can be used for internal infections, such as cold, flu and sore throats, and external problems like boils, acne, cuts, and grazes.
How can TCP be removed from water?
TCP can be removed with traditional methods such as, “pump and treat granular activated carbon filters (GAC), in-situ oxidation, permeable reactive barriers (zero-valent zinc), dechlorination by hydrogen-releasing compounds, and emerging biodegradation techniques.” A new method was developed recently using, “in-line.
What is the use of 1, 2, 3 trichloropropane?
1,2,3-Trichloropropane is used as both a chemical intermediate and cross-linking agent in the production of polymers. 1,2,3-Trichloropropane is flammable and, when heated to decomposition, emits toxic fumes of hydrogen chloride.
How is trichloropropane regulated in the United States?
The state of Alaska has promulgated standards establishing cleanup levels for 1,2,3-trichloropropane contamination in soils and groundwater. The state of California considers 1,2,3-trichloropropane to be a regulated contaminant that must be monitored.
What are the half lives of trichloropropane?
Initial and termination half-lives of unchanged 1,2,3-trichloropropane (TCP) in the blood were 0.29 and 23 hours, in the liver 0.57 and 40 hours, in the kidney 0.31 and 30 hours, in adipose tissue 1.8 and 44 hours, in the skin 0.87 and 36 hours and in muscles 1 and 45 hours.
Is there a MCL for trichloropropane in air?
On a federal scale, there is no MCL for this contaminant. The Permissible Exposure Limit (PEL) in occupational setting for air is 50 ppm or 300 mg/m 3. The concentration in air at which TCP becomes an Immediate Danger to Life and Health (IDLH) is at 100 ppm.
