Using geographic information system (GIS) and remote sensing (RS) in zoning nitrate concentration in the groundwater of Birjand, Iran [PDF]

open access: yesJournal of Advances in Environmental Health Research, 2016
Previous studies have shown that the presence of nitrate in drinking water can cause several diseases especially in the infants, such as cancer and blue baby. The Environmental Protection Agency (EPA) has since adopted the 50 mg/l standard as the maximum

Decadal changes in summertime reactive oxidized nitrogen and surface ozone over the Southeast United States [PDF]

open access: yes, 2018
Widespread efforts to abate ozone (O3) smog have significantly reduced emissions of nitrogen oxides (NOx) over the past 2 decades in the Southeast US, a place heavily influenced by both anthropogenic and biogenic emissions.

Effect of biostimulant raw materials on soybean (Glycine max) crop, when applied alone or in combination with herbicides

open access: yesFrontiers in Agronomy, 2023
IntroductionBiostimulants exert positive functions in plants, improving yield and quality, and alleviating the negative effects of abiotic stresses. Among them, the application of herbicides may cause damage to nontarget plants.

Nutrient Balance from Agricultural Pollution Sources on Selected Tributaries to the Švihov Reservoir

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2022
Agriculture is the leading source of non-point sources of water pollution, especially in terms of the runoff process. Agricultural management promotes extensive water contamination, soil erosion and sedimentation in streams and reservoirs.

Ozone and alkyl nitrate formation from the Deepwater Horizon oil spill atmospheric emissions [PDF]

open access: yes, 2012
Ozone (O3), alkyl nitrates (RONO2), and other photochemical products were formed in the atmosphere downwind from the Deepwater Horizon (DWH) oil spill by photochemical reactions of evaporating hydrocarbons with NOx (=NO+NO2) emissions from spill response
