Atrazine is an herbicide widely used for corn and is a common groundwater pollutant in the corn-producing regions of the United States. The log Kow for atrazine is 2.65. A typical application rate is 0.25 g/m2. Assume a volume of soil of 1 m3 and calculate the fraction of total atrazine that will be adsorbed to the soil given that the soil has an organic carbon content of 2.5%. The bulk density of the soil is 1.25 g/cm3; this means that each cubic centimeter of soil (soil plus water) contains 1.25 g of soil particles. The porosity of the soil is 0.4.
