NOx (pronounced "knocks") refers to nitrogen oxides, which are air pollutants that environmental professionals monitor and help reduce. Think of it like measuring and controlling car exhaust, but for bigger sources like factories and power plants. When companies need to follow environmental rules or want to be more environmentally friendly, they hire experts who understand NOx. These professionals help measure these emissions, suggest ways to reduce them, and make sure companies stay within legal limits. It's a key term that shows up in environmental consulting, especially when dealing with air quality and pollution control.
