by Brianna Crandall — March 11, 2016—The U.S. Environmental protection Agency (EPA) released for public comment and scientific peer review last week a draft risk assessment for 1-Bromopropane (1-BP) used in spray adhesives, dry-cleaning applications (including spot cleaners), and degreasing uses. EPA says the release supports “much-needed reform” of the nation’s chemicals management legislation.
The draft assessment of 1-BP, also known as n-propyl bromide, was conducted as part of EPA’s Toxic Substances Control Act (TSCA) Chemical Work Plan assessment effort. The chemical showed acute risks to women of childbearing age from adverse developmental effects. Other non-cancer and cancer health risks were identified for workers with repeated and chronic exposures, including neurotoxicity; kidney, liver and reproductive toxicity; and lung cancer.
In addition to EPA’s assessment, the National Institute of Occupational Safety and Health (NIOSH) has issued a draft criteria document for worker exposure to 1-BP, and the Agency for Toxic Substances and Disease Registry (ATSDR) examined the hazards of 1-BP associated with different exposure durations.
While each agency’s review has a distinct focus based on their mandates, they draw similar conclusions about the health hazards of 1-BP, says EPA. EPA, NIOSH, and ATSDR will continue to coordinate in addressing concerns associated with this chemical.
EPA recommends the public carefully follow product label directions and take precautions that can reduce exposures, such as using the product outside or in an extremely well ventilated area and wearing appropriate protective equipment to reduce exposure, particularly inhalation.
EPA is seeking public comment of this draft assessment for 60 days, until May 9, 2016. The document is available on Regulations.gov, docket number: EPA-HQ-OPPT-2015-0084, and will be peer reviewed by the EPA’s Chemical Safety Advisory Committee (CSAC) in the spring of 2016.
Additional information on the 1-BP draft Risk Assessment and other Work Plan Chemicals can be found on the EPA Web site.
