The cradle-to-gate inventory of acetic acid includes the following emissions to air: 5.70E-04 kg of ammonia, 1.76E-03 kg of carbon dioxide, 3.97E-03 kg of carbon monoxide, and 4.00E-05 kg of methanol. Emissions to water include 9.60E-04 kg of acetic acid and 5.20E-05 kg of ammonia. Using the information in Table 15.10, determine the mid-point environmental impact of this life cycle inventory.
