Waterways contribute to growth of potent greenhouse gas
Date:12/20/2010

ers and streams and ran their findings through a global river network model. They studied the production of nitrous oxide from the process of denitrification, in which bacteria convert nitrates to nitrogen gases.

"Even with more than 99 percent of denitrified nitrogen in streams and rivers being converted to the inert gas, dinitrogen, river networks still contribute to at least 10 percent of global anthropogenic nitrous oxide emissions," Hamilton said.

Reducing use of agricultural fertilizer and other sources of nitrogen are examples of how to decrease humanity's contribution to the growth of nitrous oxide produced in waterways, the study concluded.
