ANNOUNCEMENTS On Wednesday we will have Jamie Levin speak, who works for AC Transit. He is adamant that hydrogen is involved in the energy mix and can be used as fuel. Hydrogen can come from water or from natural gases. Both processes require energy. It is very a novel idea. On Monday, we will have the Food Services talk. Hopefully they’ll answer your questions about green products. In a week from Wednesday there will be our midterm, which will consist of true-false and multiple choice questions. It will be scantron based. You are responsible for doing one environmental sustainability audit. You can do one regarding food, water use, or energy. I sent the assignment out through bSpace. LECTURE Today I wanted to go over the issues of air and air quality. Basically, last time, I pointed out smog. Smog is free ozone plus usually some other things. It forms by photochemical reactions. The energy from the sun binds the nitrous oxides and unburned hydrocarbons together to make smog plus other nasty gases. A lot of cities in the world have the smog problem. Basically in this state we have smog problems that are worse than anywhere else in the country, in the central valley and in LA. It is a health issue in this state. When we talk about the fossil fuels, the emphasis is on global warming, climate change, and carbon dioxide. In California the biggest issue is looking at the health of the citizens living in LA and in the Central Valley. It is also bad in other parts of the world, like in China and India. When you burn anything, one reaction yields nitrous oxides, and when nitrous oxide is put in the atmosphere it reacts with water to make nitric acid. In the petroleum we burn, we do not have sulfur. Although we don’t burn coal in California, we get a lot of coal energy from Arizona and Utah. The acidity can land on fields and on lakes to make them acidic. When the lakes are high in limestone, the limestone tends to drive the acidity towards neutral or basic. The big issue with acid deposition involves the sulfur that comes out of the coal. Some petroleum has sulfur, but mostly it is refined to not
