While the Agency agrees that the observed nephrotoxic effects may be chemical-specific and not characteristic of the entire class of trialkoxysilanes, in the absence of more definitive information, a concern for nephrotoxicity should be included with the already pre- sent concern for respiratory toxicity when assessing the potential toxicity of these types of chemicals. Although EPA's receipt of information under Section 8 e does not necessarily trigger immediate regulatory action, the information that is submitted pursuant to Section 8 e does receive priority review and evaluation by EPA in order to determine an appropriate course of Agency action.
