The importance of taking the organic forms of nitrogen (ON) into account when estimating atmospheric nitrogen deposition has been known for a long time. However, there is still only a modest amount of data on organic nitrogen in rainwater worldwide,

The global wet deposition flux of ethanol is estimated to be 2.4 ± 1.6 Tg/yr with a conservative range of 0.2–4.6 Tg/yr based upon analyses of 219 wet deposition samples collected at 12 locations globally. This estimate calculated by using observe

Publikováno v: Analytical Methods. 9:2915-2922

Although there has been a dramatic increase in the use of ethanol fuel in several countries, there is a great lack of data related to the abundance of this alcohol and associated species in the atmosphere and in natural waters. This data paucity is m

Publikováno v: Atmospheric Environment. 45:5260-5265

This work concerns the influence of industrialized agriculture in the tropics on precipitation chemistry. A total of 264 rain events were sampled using a wet-only collector in central Sao Paulo State, Brazil, between January 2003 and July 2007. Elect

Publikováno v: Journal of Electroanalytical Chemistry. 584:124-130

This work presents a new electrochemically modified electrode which is chemically and mechanically stable, and can be easily constructed. It is being proposed here for the first time, a synthetic route for the monomer 5-(4-allyloxi-fenilazo)-quinolin
