Reports on E.H. Barnett's contribution of a newspaper warning addressed to people living in Big Flats Water District Two, New York about the nitrate levels in District Two wells that exceed the state recommended maximum of 10 ppm.ReeseK.M.Chemical & Engineering News (00092347)...
Groundwater ammonia pollution is well investigated worldwide as well as in Viet Nam. The products of its conversion process, namely nitrite and nitrate, cause the toxicity of ammonia in water. In addition, the existence of ammonia in water causes the modification of water taste and smell, ...

(2015) noted that several Fragilaria species are particularly competitive in waters with higher N:P ratio generated by relatively high nitrate values in oligotrophic waters, a situation found also in Lake Balma. On the other hand, Michelutti et al. (2015) associated Fragilaria nanana and Tab...
Plants adjust their RSA in response to the changing environment; for example, in the case of nutrient absorption, when roots encounter soil zones or patches containing rich nutrients, such as nitrate, ammonium, phosphate, or potassium, plants increase the lateral root biomass in the area, in ...
Given that there was documented evidence of an association between diarrhea and high nitrate ingestion, the authors examined drinking water nitrate concentration and its possible correlation(s) with methemoglobin levels, cytochrome b5 reductase activity, and recurrent diarrhea. In addition, the authors st...
We describe a new approach that couples hydrograph separation with high-frequency nitrate data to quantify time-variable groundwater and runoff loading of nitrate to streams, and the net in-stream fate of nitrate at the watershed-scale. The approach was applied at three sites spanning gradients in...
