Nitrogen oxides significantly contribute to a number of environmental effects such as acid rain and eutrophication in coastal waters like the Chesapeake Bay as well as ozone formation, all of which can have adverse effects on both terrestrial and aquatic ecosystems. Most of the higher oxides of nitrogen are eye, skin, and respiratory tract irritants. Biologic Effects of Exposure: 76-149B.PDF (66 pages, 2,510K) pdf icon: IV. Health Effects. Harmful Environmental Effects of Nitrogen Oxides Formation of ground level ozone. Nitrogen oxides other than nitrogen dioxide have also been studied for possible adverse health effects. These ranges of hydrocarbon and oxides of nitrogen levels established the HC/ NOX ratios for this study at l1/2, three, six, 12 and 24. Oxide of NitrogenSOURCES & EFFECT 2. There are no studies that have looked at the effects of gaseous nitrogen oxides on freshwaters. Nitrous oxide is relatively unreactive in the troposphere and is the main source of nitric acid and other nitrates in the stratosphere. Much of the information on oxides of nitrogen is specifically for NO 2. This data illustrate the law of Nitrogen oxides When fuels are burned in vehicle engines, high temperatures are reached. In: de Voogt P. (eds) Reviews of Environmental Contamination and Toxicology Volume 242. The very high temperature in the vicinity of a lightning bolt causes the gases oxygen and nitrogen in the air to react to form nitric oxide. Oxides of nitrogen effects? Nitrogen dioxide and nitric oxide are referred to together as oxides of nitrogen (NOx). Rev Environ Health. Harmful Health Effects of Nitrogen Oxides. The term NOx gathers mainly nitric oxide (NO) and nitrogen dioxide (NO2), mostly produced by anthropogenic activities such as transport and industries. These two forms of gaseous nitro-gen oxides are significant pollutants of the lower atmosphere. The nitrogen containing fire gases most frequently listed in fire smoke toxicity tests are hydrogen cyanide, nitrogen oxides (NOx) and, less frequently, ammonia, acrylonitrile, organo-nitriles and isocyanates (3) (4) (16). ... NO 2 itself can cause adverse effects on respiratory systems of humans and animals, and damage to vegetation. NO 2 is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year for use primarily in the production of fertilizers.At higher temperatures it is a reddish-brown gas.
