RISK CHARACTERIZATION of CARCINOGENS (STEP 4 OF EPA MODEL)
|
|
Let's start with the table we
calculated in steps 2/3... (for more worked intake examples see here)
|
|
4.186E-05 Clearly exceeds 1 in a million by almost
42 times 0.00004186 0.00000100
|
| You may also be asked WHICH chemicals must be removed (cleaned up) to reduce the risk to no more than the de-minimis level. |
|
Risk Characterization of non-carcinogens |
|
Risk-Characterization when there are multiple pathways.. |
| You can combine on INTAKE, blending the two column 6 (IF the route (oral or inhalation) is the SAME, or can blend the RISK (col 7) together if the route is different. WHEN IN DOUBT combine col. 7. |
