Summertime distribution and relations of reactive odd nitrogen species and NOyin the troposphere over Canada [PDF]
We report here large-scale features of the distribution of NOx, HNO3, PAN, particle (NO3) (-) and NOy in the troposphere from 0.15 to 6 km altitude over central Canada.

Biological aspects of reactive nitrogen species
Nitric oxide (NO) plays an important role as a cell-signalling molecule, anti-infective agent and, as most recently recognised, an antioxidant. The metabolic fate of NO gives rise to a further series of compounds, collectively known as the reactive nitrogen species (RNS), which possess their own unique characteristics.

This research studies the effects that Sb toxicity (0.0, 0.5, and 1.0 mM) has on the growth, reactive oxygen and nitrogen species, and antioxidant systems in tomato plants.

Oxygen (O2) toxicity remains a concern, particularly to the lung. This is mainly related to excessive production of reactive oxygen species (ROS). Supplemental O 2 , i.e. inspiratory O2 concentrations (FIO2) > 0.21 may cause hyperoxaemia (i.e.

Interplay between oxidant species and energy metabolism
It has long been recognized that energy metabolism is linked to the production of reactive oxygen species (ROS) and critical enzymes allied to metabolic pathways can be affected by redox reactions. This interplay between energy metabolism and ROS becomes

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

Santa Giusta Lagoon (Sardinia): phytoplankton and nutrients before and after waste water diversion [PDF]
The purpose of this paper was to assess the effect of the diversion of waste water on the trophic status of the Stagno di Santa Giusta, a hypertrophic lagoon on the centre-western coast of Sardinia.

Macrophages, reactive nitrogen species, and lung injury [PDF]
Evidence has accumulated over the past several years demonstrating that lung injury following inhalation of irritants like ozone is due, not only to direct effects of the chemical, but also indirectly to the actions of inflammatory mediators released by infiltrating macrophages.

Detection of reactive oxygen and nitrogen species by electron paramagnetic resonance (EPR) technique [PDF]
During the last decade there has been growing interest in physical-chemical oxidation processes and the behavior of free radicals in living systems. Radicals are known as intermediate species in a variety of biochemical reactions.
