New TSCA Work Plan Chemicals
TSCA/Work Plan for Existing Chemicals/Chemical Risk Assessment
June 1, 2012 EPA announced the addition of 18 chemicals to its work plan for existing chemicals risk assessment. The 18 chemicals include flame retardants, fragrance chemicals, and chlorinated hydrocarbons. Many of these chemicals are potentially carcinogenic, or pose reproductive or developmental toxicity. In addition, some of these chemicals present persistent, bioaccumulative, and toxic potential or are found in consumer products. New and existing work plan chemicals are listed on EPA’s website.
As part of the Agency’s strategy to manage existing chemicals (see EPA’s Existing Chemicals Program Strategy (PDF), EPA has been screening chemicals against risk criteria (see e.g., Identifying Priority Chemicals for Review and Assessment). Chemicals are likely to be flagged for further review and assessment if screening indicates:
- children’s health effects (e.g., chemicals with reproductive or developmental effects);
- persistence, bioaccumulation, and toxicity (PBT);
- carcinogenic effect ;
- presence in children’s products;
- presence in consumer products; and
- detection by biomonitoring programs.
In the June 1 announcement, EPA solicited unpublished health and safety studies on these chemicals. Research should be submitted to docket EPA-HQ-OPPT-20110-516 by August 31, 2012. Health and safety studies comprise “any study of any effect of a chemical substance or mixture on health or the environment or on both,” including but not limited to:
- Epidemiological or clinical studies;
- Studies of occupational exposure;
- In vivo and in vitro toxicological studies; and
- Ecotoxicological studies;
Risks assessments on the new work plan chemicals will be conducted in 2013 and 2014.
