    Please read the attached paper and answer the following questions.

    1. Calculate the total cumulative Zn and Cu loading (kg/ha) from sludge on the West Bennett B site between 1982-1992. Note that there are three application rates: 7, 14, 28 Mg/ha (metric tons of sludge added per hectare), and therefore three loadings for each metal.

    2. Convert the Zn and Cu loadings in question 2 into expected increases in soil concentrations (mg/kg) when the sludges are tilled into the 0-15 cm soil layer. Assume a soil bulk density of 1.3 g/cm 3 .
