A total of 2 metric tons of atrazine was released into the environment (20oC) after an accidental spill. The soil has the following properties: fraction of organic carbon 2.5%, bulk density 1.75 g/cm3, empirical equation, log Koc = 0.937 log Kow 0.006. The fish has the following properties: density 2.1 g/cm3, bioconcentration factor (BCF) 8.1 cm3/g. The volumes in the four phases are as follows: Volume of air: 1 x 1010 m3 Volume of water: 8 x 108 m3 Volume of soil: 7 x 107 m3 Volume of fish: 4 x 104 m3 Given infinite time for the released atrazine to spread with no remedial action taken, what will be the mass and percentage of atrazine (in kg) in each of the four phases?
