Hydrologists find Mississippi River network's buffering system nitrates is overwhelmed
2014/6/12
AUSTIN, Texas — A new method of measuring the interaction of surface water and groundwater along the length of the Mississippi River network adds fresh evidence that the network’s natural ability to c...
Attempts to Answer on the Origin of the High Nitrates Concentrations in Groundwaters of the Sourou Valley in Burkina Faso
Burkina Faso Sourou Groundwaters Nitrates Pollution
2013/3/19
Within the framework of the contract of Sourou River, a survey of the groundwater quality was performed through 7 campaigns of water sampling and analysis from 2006 till 2012. The water samples result...
Isoprene nitrates: preparation, separation, identification, yields, and atmospheric chemistry
Isoprene nitrates atmospheric chemistry
2010/8/16
Isoprene is an important atmospheric volatile organic compound involved in ozone production and NOx (NO+NO2) sequestration and transport. Isoprene reaction with OH in the presence of NO can form eithe...

Closing the peroxy acetyl nitrate budget: observations of acyl peroxy nitrates (PAN, PPN, and MPAN) during BEARPEX 2007
peroxy acetyl nitrate budget acyl peroxy nitrates BEARPEX 2007
2009/10/13
Acyl peroxy nitrates (APNs, also known as PANs) are formed from the oxidation of aldehydes and other oxygenated VOC (oVOC) in the presence of NO2. There are both anthropogenic and biogenic oVOC precur...
