Global Warming Solutions Act of 2006 a 30% reduction statewide, with mandatory caps beginning in 2012 for significant emissions sources. The bill also allows the Governor to suspend the emissions caps for up to a year in case of emergency or significant economic harm. The State of California leads the nation in energy efficiency standards and plays a lead role in environmental protection, but is also the 12th largest emitter of carbon worldwide. Greenhouse gas emissions are defined in the bill to include all of the following: carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons and perfluorocarbons. These are the same greenhouse gases listed in Annex
Nitrous oxide B levels should be checked in people with risk factors for vitamin B deficiency prior to using nitrous oxide anaesthesia. Several experimental studies in rats indicate that chronic exposure of pregnant females to nitrous oxide may have adverse effects on the developing fetus. At room temperature (20 °C (68 °F)) the saturated vapour pressure is 50.525 bar, rising up to 72.45 bar at —the critical temperature. The pressure curve is thus unusually sensitive to temperature. Liquid nitrous oxide acts as a good solvent for many organic compounds; liquid mixtures may form shock sensitive explosives. As with many strong oxidisers, contamination
