Homing in on sources and yields of nitrogen and phosphorus throughout the Mississippi/Atchafalaya River Basin
A new USGS study estimates total nitrogen (N) and total phosphorus (P) yields from catchments throughout the Mississippi/Atchafalaya River Basin, which drains about 41% of the conterminous United States.
Chemical mixtures are common in small streams in the U.S.
Mixtures of organic chemicals are ubiquitous in small U.S. streams, reports a new study by the U.S. Geological Survey. In many streams the mixtures could be affecting stream organisms.
