4. Diesel Particulate Matter (10 points) a.) What are some of the challenges in controlling the levels of diesel particulate matter in air? b.) Why would controlling diesel particulate matter be beneficial for mitigating climate change? c) The NAAQS for PM2 s is set at 35 g/m3 (24-hr average). The 24-hr average PMs concentration in Klamath Falls, a small town in Oregon, from 2007-2009 was 45 ug/m. Let's assume that 4 % of the PM2.5 concentration is diesel. The ambient benchmark concentration for diesel PM is 0.1 ug/m i.) Calculate the excess cancer risk due to diesel PM in Klamath Falls .) What does the number that you calculated mean in terms of risk?

Explanation / Answer

Control of diesel particulate matter is extremely beneficial, as diesel emissions contain NOx, SOx, methane and other greenhouse gas emissions that lead to global warming. These gases cause acid rain, and are known to cause human respiratory problems and other health complications. Hence, controlling such emissions is highly essential.
