Discussion Forum: Identifying Priority Chemicals for Review and Assessment http://blog.epa.gov/chemprioritization Office of Pollution Prevention and Toxics Mon, 16 Apr 2012 17:45:26 +0000 en-US hourly 1 http://wordpress.org/?v=3.5.1 Step 2 Topic: Data Sources for Further Analysis http://blog.epa.gov/chemprioritization/2011/08/step-2-topic/?utm_source=rss&utm_medium=rss&utm_campaign=step-2-topic http://blog.epa.gov/chemprioritization/2011/08/step-2-topic/#comments Fri, 05 Aug 2011 16:50:38 +0000 rbrinkhu https://blog.epa.gov/chemprioritization/?p=28 After identifying a group of chemicals for priority review using the factors and data sources in Step 1, EPA in Step 2 plans to use information from additional exposure and hazard data sources to further analyze the chemicals to select specific chemicals for further assessment, including possible risk assessment and risk management action under TSCA.

EPA invites your thoughts on the exposure data sources listed in Table 2 and the hazard data sources listed in Table 3 that the Agency intends to use in this further analysis, including:

  • Should additional data sources beyond those listed in Tables 2 and 3 be included? What sources, and why?
  • Please explain your concerns or comments, if any, relating to the data sources featured in Tables 2 and 3.
  • Please discuss which data sources, if any, should receive greater consideration for analysis than others.

  • Which other data sources, in addition to those listed in Table 1, should the Agency consider in order identifying chemicals that meet the listed factors?  Why should such data sources be added?
  • For any additional priority criteria factors you might propose, what data sources should be considered to identify chemicals meeting those factors?
  • Please explain your concerns or comments, if any, relating to the data sources featured in Table 1.
  • Please discuss which data sources, if any, should receive greater consideration than others.

In Step 1, EPA plans to use a specific set of data sources to identify candidate chemicals that meet one or more of these priority factors:

  • Chemicals identified as potentially of concern for children’s health (e.g., chemicals with reproductive or developmental effects).
  • Chemicals identified as persistent, bioaccumulative, and toxic (PBT).
  • Chemicals identified as probable or known carcinogens.
  • Chemicals used in children’s products.
  • Chemicals used in consumer products.
  • Chemicals detected in biomonitoring programs.

EPA invites your thoughts on these prioritization factors, including:

  • What other factors, if any, should the Agency add, and why?
  • Please discuss which prioritization factors, if any, should receive greater consideration than others.
