Human activities add large quantities of nitrogen to the environment, much of which gets washed into streams and rivers. These waterways transport some of that nitrogen to the oceans, but they also ...

An study led by researchers from the Harbin Institute of Technology has unveiled a substantial development in wastewater treatment technology. Published in Engineering, the research introduces an ...

After more than a decade of inquiry, a team of scientists has turned the tables on a long-standing controversy to re-establish an old truth about nitrogen mixing in the oceans. After more than a ...

Limnology and Oceanography, Vol. 61, No. 2 (2016), pp. 610-624 (15 pages) To evaluate the relation of isotope fractionation during sedimentary nitrate reduction with sediment reactivity, we measured ...

Excess nitrogen from agricultural and urban lands is contaminating groundwater, streams, lakes and estuaries, where it causes harmful algal blooms and contributes to fish kills. Cost-effective ...

Denitrification is a microbial respiratory process in which oxidized nitrogen species, primarily nitrate (NO₃⁻) and nitrite (NO₂⁻), are sequentially reduced to gaseous forms such as nitric oxide (NO), ...

By tracing the exact microbial pathways responsible for N₂O production, the scientists reveal why the same soil amendment ...

Zhang Y.K. and Yang, H. (2026) Research on the Application of Nitrogen Removal Technology for Rural Sewage Based on Embedded ...
