2)
A property located one half mile downwind from the former site of a
specialty chemical company has undergone air monitoring with the
following average concentrations detected for three VOCs:
|
VOC |
24 Hr Ave. Conc. (mg/m3) |
RfC (mg/m3) |
|
Perchloroethylene |
0.025 |
0.0400 |
|
Trichloroethylene |
0.002 |
0.0019 |
|
Toluene |
0.100 |
5.0000 |
a)
Calculate the hazard ratio for each individual VOC
b)
Assuming that the toxic effects are additive, evaluate whether
exposure to this mixture would be hazardous
