In the earlier problem it was found that

the city water was contaminated with

benzene and a resident has been

exposed to benzene through, ingestion,

dermal $($swimming and shower$),$

inhalation pathways. Following daily

intake values were determined:

CDI $-$ ingestion $={1\mathrm{.}24}^{**}{10}^{-4}m\frac{g}{k}g.d$

CDI $-$ ingestion $($swimming$)=4\mathrm{.}11**{10}^{-7}$

$m\frac{g}{k}g.$d

CDI$-$Dermal $($shower$)={1\mathrm{.}04}^{**}{10}^{-6}$

$m\frac{g}{k}g.d$

CDI$-$Dermal $($swimming$)={3\mathrm{.}19}^{**}{10}^{-5}$

$m\frac{g}{k}g.d$

Inhalation $($showering$)=1\mathrm{.}71**{10}^{-5}$

$m\frac{g}{k}g.d$

Estimate the risk from exposure to drinking

water containing the MCL of benzene
