Table 6. Definition of parameters and notes to tables
| Parameter/Value | Definition |
| CAS No. | Chemical Abstract Service Identification Number for Chemical Substances |
| Surrogate? | "Yes" indicates compound was quantified by GC/MS total-ion-current (TIC) method using mixture of 12 common hydrocarbons as calibration references |
| Chronic REL | Chronic Reference Exposure Level (REL) established by Cal/EPA Office of Environmental Health Hazard Assessment, Aug. 2003 and adopted by Section 01350 as target IAQ limit for building; for formaldehyde, IAQ limit is 33 µg m-3 rather than REL. No material may contribute more than ½ IAQ limit for any REL compound |
| CARB TAC Cat. | Toxic Air Contaminant (TAC) on Cal/EPA Air Resources Board list, Dec. 1999, with toxic category indicated |
| Prop 65 List? | "Yes" indicates compound is chemical known to cause cancer or reproductive toxicity listed by Calf. Sate Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65), Feb. 2003 |
| 96-hr Chamber Conc. | Measured chamber VOC concentration at final 96-hr time point minus any analytical blank or blank concentration for empty chamber operated following same procedure. Lower limit of quantitation (LOQ) for individual VOCs on list of toxicants is 2 µg m-3. Based on a 2 ng limit for a 1-liter sample. LOQ for TVOC is 20 µg m-3. LOQ for formaldehyde and acetaldehyde is given below. |
| Emission Factor | Mass of compound emitted per square meter of material per hour (calculations shown below). Reporting limits for emission factors are established by LOQ or reporting limit for chamber concentration and material's exposed surface area. |
| Classroom/Office/Other Bldg Conc. | Concentrations for standard school classroom, hypothetical office building, or specific project building calculated using parameters given in Table 3 (calculations shown below). |
| TVOC | Total Volatile Organic Compounds quantified by GC/MS TIC method using mixture of 12 common hydrocarbons as calibration references |
| Formaldehyde & Acetaldehyde | Volatile aldehydes quantified by HPLC following ASTM Method D 5197-97. LOQ for formaldehyde and acetaldehyde is approximately 1 µg m-3. |
| Individual VOCs | Quantified by thermal desorption GC/MS following EPA methods TO-1 and TO-17. Compound was quantified using multi-point calibration prepared with pure substance unless otherwise indicated (see Surrogate?). VOCs with chronic RELs are listed first, followed by other TAC and Prop. 65 compounds. Additional abundant VOCs at or above reporting limit of 5 µg m-3 are listed last. VOCs are listed in order of decreasing volatility within each group. |
| "<" | "Less than" concentrations established by LOQ |
| "LQ" | Indicates calculated value is below quantitation based on concentration LOQ |
| "na" | Not applicable |
