Climate change in Washington The main Global greenhouse Gas released in Washington include carbon dioxide (CO), methane (CH4), nitrous oxide (N2O), and other gases that contribute to global warming. The different emission types are placed into three categories: energy, industrial processes and agriculture. Different greenhouse gases range in their individual impact on global warming. For instance, one pound of nitrous oxide is 296 times more potent than a pound of carbon dioxide in contributing to global warming. This means even small quantities of gases emitted into the environment, like nitrous oxide, can have significant impacts on global warming. For Washington state in particular, energy
Nitrous oxide Because nitrous oxide is minimally metabolised in humans (with a rate of 0.004%), it retains its potency when exhaled into the room by the patient, and can pose an intoxicating and prolonged exposure hazard to the clinic staff if the room is poorly ventilated. Where nitrous oxide is administered, a continuous-flow fresh-air ventilation system or scavenger system is used to prevent a waste-gas buildup. The National Institute for Occupational Safety and Health recommends that workers' exposure to nitrous oxide should be controlled during the administration of anaesthetic gas in medical, dental, and veterinary operators. It set a recommended exposure limit
