1,2-Dichloroethane is a volatile organic compound that was once added to gasoline along with the
heavy metal lead. At many former gasoline storage sites, the unsaturated soil and groundwater are
still contaminated with 1,2-dichloroethane.
One of the concerns with volatile organic compounds in the unsaturated zone of soil is that
they can diffuse into buildings and contaminate the air. Calculate the concentration of 1,2-
dichloroethane in air that will result in a carcinogenic risk of 104, based on a breathing rate
of 11.3 m/d, exposure for 10 hours per day, and an inhalation PF of 9.1x102 kg•d/mg.
Express your answer in µg/m³.
А.
Calculate the concentration of 1,2-dichloroethane in groundwater that will result in a hazard
quotient of 1, based on drinking 2 L of water per day for a lifetime and an oral RfD of 0.012
mg/(kg d). Express your answer in ppb.
В.
The enthalpy change for the dissolution of
sulphuric acid in water is -75.0kJ/mol.
Concentrated sulphuric acid is an 18.1M
solution. Calculate how much the temperature
of the solution would change if you were
making 1.38L of pH -0.56 H2SO4. Assume the
solution has the same heat of solution as
water, 4.186 kJ/Kg °C and the density of
concentrated H2SO4 is 1.840 kg/L. Only your
final answer is required to three sig figs.
