WASHINGTON – The U.S. Environmental Protection Agency (EPA) released a final risk assessment for trichloroethylene (TCE). The assessment identified health risks from TCE exposures to consumers using spray aerosol degreasers and spray fixatives. It also identifies health risks to workers when TCE is used as a degreaser in small commercial shops and as a stain removing agent in dry cleaning.
“EPA calls on Congress to enact legislation that strengthens our current federal toxics law,” said Jim Jones, assistant administrator for chemical safety and pollution prevention. “Until that time, we are using the best available science to assess and address chemical risks of TCE that now show that it may harm human health and the environment.”
The final TCE risk assessment was developed as part of the agency’s Toxic Substances Control Act (TSCA) Work Plan, which identified chemicals for review and assessment of potential risks to people’s health and the environment. EPA developed the draft TCE risk assessment based on the best available information and finalized the assessment after careful consideration of comments from the public and experts during an independent, scientific peer review of the assessment. TCE is the first chemical to complete the work plan risk assessment process under TSCA.

Methylene chloride is a volatile organic compound widely used as a solvent in numerous applications, including adhesives, pharmaceuticals, metal degreasers, chemical processes, and aerosols, as well as paint strippers. EPA classifies the chemical as “likely to be carcinogenic in humans.”

EPA is considering voluntary and regulatory actions to reduce the risks to workers and consumers from exposure to methylene chloride. The agency says it plans to meet with stakeholders and the public to determine potential alternatives to DCM in paint strippers and other ways to reduce exposure to the chemical.

Also on Aug. 28, EPA released assessments for two other chemicals—antimony trioxide, used in halogenated flame retardants, and 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[γ]-2-benzopyran (HHCB), a fragrance ingredient. The agency did not identify any significant ecological risks with either substance. EPA says it did not examine the human health risks of either of the chemicals because the agency determined that such risks are likely to be low.

The just-released assessments are three of dozens expected to be released under an EPA effort to review the safety of 83 chemicals under the Toxic Substances Control Act. The results could lead EPA to ban, restrict, or require labeling of the chemicals or declare them safe for current uses.

Ethylene Glycol Toxicity

Written by

Several toxic alcohols are of medical and toxicological importance; the principal ones include ethanol, ethylene glycol (EG), methanol, and isopropanol. See Alcohol Toxicity. This article discusses ethylene glycol, which is extremely toxic. If untreated, ingestion of ethylene glycol can be fatal.

Ethylene glycol is the major ingredient of almost all radiator fluid products in the United States. It is used to increase the boiling point and decrease the freezing point of radiator fluid, which circulates through the automotive radiator. These changes to the boiling and freezing points result from the colligative properties of the solute (ie, they depend on the number of particles in the solution). Hence, ethylene glycol is added to prevent the radiator from overheating or freezing, depending on the season. Fluorescein dye is often added to radiator fluid to help mechanics identify the source of a radiator leak. The fluorescein in the fluid fluoresces when viewed under ultraviolet light.

Ethylene glycol tastes sweet, which is why some animals are attracted to it. Many veterinarians are familiar with ethylene glycol toxicity because of the frequent cases that involve dogs or cats that drink radiator fluid.

Initially, patients with ethylene glycol intoxication may be asymptomatic; with time they will develop altered mental status and dyspnea. The classic laboratory profile is an early osmolar gap that later transitions to an anion gap metabolic acidosis. Initial treatment includes infusion of crystalloids to enhance renal clearance of the toxic metabolites. Ethyl alcohol has traditionally been used for antidotal treatment, but it has largely been supplanted by fomepizole.

Dibutyl Phthalate

Dibutyl Phthalate (DBP) is a commonly used plasticizer. It is also used as an additive to adhesives or printing inks. It is soluble in various solvents, e.g. in alcohol, ether and benzene. Dibutyl Phthalate (DBP) is also used as an ectoparasiticide. If your organization is in need of this material….We've got it in stock Drum quantities available! Call 855-TEX-CHEM for details!
