State-of-the-art and perspectives of the catalytic and electrocatalytic reduction of aqueous nitrates

, 2017
Nitrate pollution of groundwater, which is mainly caused by the application of nitrogen-based fertilizers in intensive agriculture, is a widespread problem all over the world and a potential risk for public health.

Aircraft based four-channel thermal dissociation laser induced fluorescence instrument for simultaneous measurements of NO2, total peroxy nitrate, total alkyl nitrate, and HNO3 [PDF]

, 2013
A four-channel thermal dissociation laser induced fluorescence (TD-LIF) instrument has been developed for simultaneous measurements of nitrogen dioxide (NO2), total peroxy nitrate (∑PNs), total alkyl nitrate (∑ANs) and nitric acid (HNO3). NO2 is measured

Vasodilator Therapy: Nitrates and Nicorandil

Cardiovascular Drugs and Therapy, 2016
Nitrates have been used to treat symptoms of chronic stable angina for over 135 years. These drugs are known to activate nitric oxide (NO)-cyclic guanosine-3′,-5′-monophasphate (cGMP) signaling pathways underlying vascular smooth muscle cell relaxation ...

The glycogen accumulation in cells of Chlorobium limicola under the conditions of the disruption of some steps of the Arnon’ cycle

Біологічні студії, 2010
Nitrates are not utilized by photosynthetic green sulfur bacteria Chlorobium limicola as the nitrogen source. Addition of these compounds into the medium inhibits the growth of bacteria but stimulates the glycogen accumulation.

The influence of nitrate leaching through unsaturated soil on groundwater pollution in an agricultural area of the Basque country: a case study [PDF]

, 2003
The average nitrate concentration in the groundwater of the Vitoria-Gasteiz (Basque Country) quaternary aquifer rose from 50 mg NO3−/l during 1986 to over 200 mg/l in 1995, which represents an increase of some 20 mg NO3−/l per year.
