NYC 9/11 Public Portal Document
Lead 13 samples were above the health-based benchmark of 25 ug/ft2 and 17 samples were below the analytical sensitivity of 20 ug/ft2. PAH 30 samples were below the reporting limit of 5ug. The resulting TEF for each sample would be 580 ug/m2 which is above the current health-based benchmark of 300 ug/m2. This is why a reporting limit of I ug should be used (i.e., item #1 above). I look forward to seeing the dioxin and silica data when it is ready to be released. Thanks, Chuck Nace Environmental Toxicologist
