Increasing Nitrogen Pollution Overwhelms Filtering Capability of Streams
Nationwide study says excess nitrogen loading reduces pollution-filtering efficiency of stream and river networks
MBL, Woods Hole, MA—Increasing nitrogen runoff from urban and agriculture land-use is interfering with our streams’ and rivers’ natural processes for reducing this pollutant before it endangers delicate downstream ecosystems, reports a nationwide team of 31 ecologists, including two from the MBL (Marine Biological Laboratory) Ecosystems Center....More>>>
