Newly Published Weight of Evidence Manuscript
Supports US EPA Proposed Criteria for NP
April 19, 2005
A recently published manuscript1 in the Human and Ecological Risk Assessment journal provided a weight of evidence hazard assessment using a robust statistical technique known as Species Sensitivities Distribution (SSD). About 90 chronic toxicity values from high quality peer-reviewed studies were evaluated. Using the SSD analysis for nonylphenol (NP) the authors calculated a chronic safe level of 5.7 ug/L, which supports the draft US EPA criteria for NP of 5.9 ug/L.
