Problem
Phthalate esters are used as plasticizers. Di-n-butyl phthalate (DBP) is found both in marine waters and the atmosphere. The mean concentrations in the Gulf of Mexico are 94 ng/L in surface water and 0.3 ng/m3 in air. Estimate the direction and magnitude of the annual flux of DBP. The reported vapor pressure and aqueous solubility of DBP at 25oC are 1.4 × 10-5 mm Hg and 3.25 mg/L, respectively (Giam et al., 1978).
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
