Problem
The concentration of a pesticide (chlorpyrifos) measured in air from a foggy atmosphere in Parlier, CA, was 17.2 ng/m3 at about 25oC. The Henry's constant for chlorpyrifos at 25oC is 170 × 10-6 and the air-water partition constant is 6.4 × 10-4 at 12.5oC. The average fog diameter is 1μm. If the fog deposition rate is 0.2 mm/h, and the fog lasts for 4 h, what is the surface flux of chlorpyrifos?
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.
