Estimating Production Data for Five Engineered Nano-materials As a Basis for Exposure Assessment

An inadvertent production problem resulted in an error in the text of the version published on March 10, 2011. The section entitled Data Quality on page 2564 was corrected to read "The uncertainty inherent to these estimations is such a barrier to identifying true ENM production levels that it warrants explicit inclusion in the results; it is not only important because it affects the final results but is actually a key finding in itself.
