Section 10.4 of Chapter 10 examines a case study concerning air pollution in a real-world environment. Describe the sampling site locations and particulate matter sizes sampled; list three PAH’s that were sampled. Explain how the AirmetricsMiniVol portable air sampler works. Which location in the case study had the highest average mass concentration of PM2.5? Why? What type of cooking (deep-frying, stir-frying, or boiling) results in the highest PM2.5 concentrations and thereby poses the highest health risks?
